----------------------------------------
8 May 2018. Summary of changes for version 20180508:


1) ACPICA kernel-resident subsystem:

Completed the new (recently deployed) package resolution mechanism for 
the Load and LoadTable ASL/AML operators. This fixes a regression that 
was introduced in version 20180209 that could result in an 
AE_AML_INTERNAL exception during the loading of a dynamic ACPI/AML table 
(SSDT) that contains package objects.


2) iASL Compiler/Disassembler and Tools:

AcpiDump and AcpiXtract: Implemented support for ACPI tables larger than 
1 MB. This change allows for table offsets within the acpidump file to be 
up to 8 characters. These changes are backwards compatible with existing 
acpidump files.


----------------------------------------
27 April 2018. Summary of changes for version 20180427: 


1) ACPICA kernel-resident subsystem:

Debugger: Added support for Package objects in the "Test Objects" 
command. This command walks the entire namespace and evaluates all named 
data objects (Integers, Strings, Buffers, and now Packages).

Improved error messages for the namespace root node. Originally, the root 
was referred to by the confusing string "\___". This has been replaced by 
"Namespace Root" for clarification.

Fixed a potential infinite loop in the AcpiRsDumpByteList function. Colin 
Ian King <colin.king@canonical.com>.


2) iASL Compiler/Disassembler and Tools: 

iASL: Implemented support to detect and flag illegal forward references. 
For compatibility with other ACPI implementations, these references are 
now illegal at the root level of the DSDT or SSDTs. Forward references 
have always been illegal within control methods. This change should not 
affect existing ASL/AML code because of the fact that these references 
have always been illegal in the other ACPI implementation.

iASL: Added error messages for the case where a table OEM ID and OEM 
TABLE ID strings are longer than the ACPI-defined length. Previously, 
these strings were simply silently truncated.

iASL: Enhanced the -tc option (which creates an AML hex file in C, 
suitable for import into a firmware project):
  1) Create a unique name for the table, to simplify use of multiple 
SSDTs.
  2) Add a protection #ifdef in the file, similar to a .h header file.
With assistance from Sami Mujawar, sami.mujawar@arm.com and Evan Lloyd, 
evan.lloyd@arm.com

AcpiExec: Added a new option, -df, to disable the local fault handler. 
This is useful during debugging, where it may be desired to drop into a 
debugger on a fault.

----------------------------------------
13 March 2018. Summary of changes for version 20180313:


1) ACPICA kernel-resident subsystem:

Implemented various improvements to the GPE support:

1) Dispatch all active GPEs at initialization time so that no GPEs are 
lost.
2) Enable runtime GPEs earlier. Some systems expect GPEs to be enabled 
before devices are enumerated.
3) Don't unconditionally clear ACPI IRQs during suspend/resume, so that 
IRQs are not lost.
4) Add parallel GPE handling to eliminate the possibility of dispatching 
the same GPE twice.
5) Dispatch any pending GPEs after enabling for the first time.

AcpiGetObjectInfo - removed support for the _STA method. This was causing 
problems on some platforms.

Added a new _OSI string, "Windows 2017.2".

Cleaned up and simplified the module-level code support. These changes 
are in preparation for the eventual removal of the legacy MLC support 
(deferred execution), replaced by the new MLC architecture which executes 
the MLC as a table is loaded (DSDT/SSDTs).

Changed a compile-time option to a runtime option. Changes the option to 
ignore ACPI table load-time package resolution errors into a runtime 
option. Used only for platforms that generate many AE_NOT_FOUND errors 
during boot. AcpiGbl_IgnorePackageResolutionErrors.

Fixed the ACPI_ERROR_NAMESPACE macro. This change involves putting some 
ACPI_ERROR_NAMESPACE parameters inside macros. By doing so, we avoid 
compilation errors from unused variables (seen with some compilers).


2) iASL Compiler/Disassembler and Tools:

ASLTS: parallelized execution in order to achieve an (approximately) 2X 
performance increase.

ASLTS: Updated to use the iASL __LINE__ and __METHOD__ macros. Improves 
error reporting.

----------------------------------------
09 February 2018. Summary of changes for version 20180209:


1) ACPICA kernel-resident subsystem:

Completed the final integration of the recent changes to Package Object 
handling and the module-level AML code support. This allows forward 
references from individual package elements when the package object is 
declared from within module-level code blocks. Provides compatibility 
with other ACPI implementations.

The new architecture for the AML module-level code has been completed and 
is now the default for the ACPICA code. This new architecture executes 
the module-level code in-line as the ACPI table is loaded/parsed instead 
of the previous architecture which deferred this code until after the 
table was fully loaded. This solves some ASL code ordering issues and 
provides compatibility with other ACPI implementations. At this time, 
there is an option to fallback to the earlier architecture, but this 
support is deprecated and is planned to be completely removed later this 
year.

Added a compile-time option to ignore AE_NOT_FOUND exceptions during 
resolution of named reference elements within Package objects. Although 
this is potentially a serious problem, it can generate a lot of 
noise/errors on platforms whose firmware carries around a bunch of unused 
Package objects. To disable these errors, define 
ACPI_IGNORE_PACKAGE_RESOLUTION_ERRORS in the OS-specific header. All 
errors are always reported for ACPICA applications such as AcpiExec.

Fixed a regression related to the explicit type-conversion AML operators 
(ToXXXX). The regression was introduced early in 2017 but was not seen 
until recently because these operators are not fully supported by other 
ACPI implementations and are thus rarely used by firmware developers. The 
operators are defined by the ACPI specification to not implement the 
"implicit result object conversion". The regression incorrectly 
introduced this object conversion for the following explicit conversion 
operators:
    ToInteger
    ToString
    ToBuffer
    ToDecimalString
    ToHexString
    ToBCD
    FromBCD


2) iASL Compiler/Disassembler and Tools:

iASL: Fixed a problem with the compiler constant folding feature as 
related to the ToXXXX explicit conversion operators. These operators do 
not support the "implicit result object conversion" by definition. Thus, 
ASL expressions that use these operators cannot be folded to a simple 
Store operator because Store implements the implicit conversion. This 
change uses the CopyObject operator for the ToXXXX operator folding 
instead. CopyObject is defined to not implement implicit result 
conversions and is thus appropriate for folding the ToXXXX operators.

iASL: Changed the severity of an error condition to a simple warning for 
the case where a symbol is declared both locally and as an external 
symbol. This accommodates existing ASL code.

AcpiExec: The -ep option to enable the new architecture for module-level 
code has been removed. It is replaced by the -dp option which instead has 
the opposite effect: it disables the new architecture (the default) and 
enables the legacy architecture. When the legacy code is removed in the 
future, the -dp option will be removed also.

----------------------------------------
05 January 2018. Summary of changes for version 20180105:


1) ACPICA kernel-resident subsystem:

Updated all copyrights to 2018. This affects all source code modules.

Fixed a possible build error caused by an unresolved reference to the 
AcpiUtSafeStrncpy function.

Removed NULL pointer arithmetic in the various pointer manipulation 
macros. All "(void *) NULL" constructs are converted to "(void *) 0". 
This eliminates warnings/errors in newer C compilers. Jung-uk Kim.

Added support for A32 ABI compilation, which uses the ILP32 model. Anuj 
Mittal.


2) iASL Compiler/Disassembler and Tools:

ASLTS: Updated all copyrights to 2018.

Tools: Updated all signon copyrights to 2018.

AcpiXtract: Fixed a regression related to ACPI table signatures where the 
signature was truncated to 3 characters (instead of 4).

AcpiExec: Restore the original terminal mode after the use of the -v and 
-vd options.

ASLTS: Deployed the iASL __METHOD__ macro across the test suite.

----------------------------------------
14 December 2017. Summary of changes for version 20171214:


1) ACPICA kernel-resident subsystem:

Fixed a regression in the external (public) AcpiEvaluateObjectTyped 
interface where the optional "pathname" argument had inadvertently become 
a required argument returning an error if omitted (NULL pointer 
argument).

Fixed two possible memory leaks related to the recently developed "late 
resolution" of reference objects within ASL Package Object definitions.

Added two recently defined _OSI strings: "Windows 2016" and "Windows 
2017". Mario Limonciello.

Implemented and deployed a safer version of the C library function 
strncpy:  AcpiUtSafeStrncpy. The intent is to at least prevent the 
creation of unterminated strings as a possible result of a standard 
strncpy.

Cleaned up and restructured the global variable file (acglobal.h). There 
are many changes, but no functional changes.


2) iASL Compiler/Disassembler and Tools:

iASL Table Compiler: Fixed a problem with the DBG2 ACPI table where the 
optional OemData field at the end of the table was incorrectly required 
for proper compilation. It is now correctly an optional field.

ASLTS: The entire suite was converted from standard ASL to the ASL+ 
language, using the ASL-to-ASL+ converter which is integrated into the 
iASL compiler. A binary compare of all output files has verified the 
correctness of the conversion.

iASL: Fixed the source code build for platforms where "char" is unsigned. 
This affected the iASL lexer only. Jung-uk Kim.

----------------------------------------
10 November 2017. Summary of changes for version 20171110:


1) ACPICA kernel-resident subsystem:

This release implements full support for ACPI 6.2A:
    NFIT - Added a new subtable, "Platform Capabilities Structure"
No other changes to ACPICA were required, since ACPI 6.2A is primarily an 
errata release of the specification.

Other ACPI table changes:
    IORT: Added the SMMUv3 Device ID mapping index. Hanjun Guo
    PPTT: Added cache attribute flag definitions to actbl1.h. Jeremy 
Linton

Utilities: Modified the string/integer conversion functions to use 
internal 64-bit divide support instead of a native divide. On 32-bit 
platforms, a 64-bit divide typically requires a library function which 
may not be present in the build (kernel or otherwise).

Implemented a targeted error message for timeouts returned from the 
Embedded Controller device driver. This is seen frequently enough to 
special-case an AE_TIME returned from an EC operation region access:
    "Timeout from EC hardware or EC device driver"

Changed the "ACPI Exception" message prefix to "ACPI Error" so that all 
runtime error messages have the identical prefix.


2) iASL Compiler/Disassembler and Tools:

AcpiXtract: Fixed a problem with table header detection within the 
acpidump file. Processing a table could be ended early if a 0x40 (@) 
appears in the original binary table, resulting in the @ symbol appearing 
in the decoded ASCII field at the end of the acpidump text line. The 
symbol caused acpixtract to incorrectly think it had reached the end of 
the current table and the beginning of a new table.

AcpiXtract: Added an option (-f) to ignore some errors during table 
extraction. This initial implementation ignores non-ASCII and non-
printable characters found in the acpidump text file.

TestSuite(ASLTS)/AcpiExec: Fixed and restored the memory usage statistics 
for ASLTS. This feature is used to track memory allocations from 
different memory caches within the ACPICA code. At the end of an ASLTS 
run, these memory statistics are recorded and stored in a log file.

Debugger (user-space version): Implemented a simple "Background" command. 
Creates a new thread to execute a control method in the background, while 
control returns to the debugger prompt to allow additional commands.
    Syntax: Background <Namepath> [Arguments]

----------------------------------------
29 September 2017. Summary of changes for version 20170929:


1) ACPICA kernel-resident subsystem:

Redesigned and implemented an improved ASL While() loop timeout 
mechanism. This mechanism is used to prevent infinite loops in the kernel 
AML interpreter caused by either non-responsive hardware or incorrect AML 
code. The new implementation uses AcpiOsGetTimer instead of a simple 
maximum loop count, and is thus more accurate and constant across 
different machines. The default timeout is currently 30 seconds, but this 
may be adjusted later.

Renamed the ACPI_AML_INFINITE_LOOP exception to AE_AML_LOOP_TIMEOUT to 
better reflect the new implementation of the loop timeout mechanism.

Updated the AcpiGetTimerDuration interface to cleanup the 64-bit support 
and to fix an off-by-one error. Jung-uk Kim.

Fixed an EFI build problem by updating the makefiles to for a new file 
that was added, utstrsuppt.c


2) iASL Compiler/Disassembler and Tools:

Implemented full support for the PDTT, SDEV, and TPM2 ACPI tables. This 
includes support in the table disassembler, compiler, and template 
generator.

iASL: Added an exception for an illegal type of recursive method 
invocation. If a method creates named objects, the first recursive call 
will fail at runtime. This change adds an error detection at compile time 
to catch the problem up front. Note: Marking such a method as 
"serialized" will not help with this problem, because the same thread can 
acquire the method mutex more than once. Example compiler and runtime 
output:

    Method (MTH1)
    {
        Name (INT1, 1)
        MTH1 ()
    }

    dsdt.asl     22: MTH1 ()
    Error    6152 -  ^ Illegal recursive call to method
                       that creates named objects (MTH1)

Previous runtime exception:
    ACPI Error: [INT1] Namespace lookup failure,
    AE_ALREADY_EXISTS (20170831/dswload2-465)

iASL: Updated support for External() opcodes to improve namespace 
management and error detection. These changes are related to issues seen 
with multiple-segment namespace pathnames within External declarations, 
such as below:

    External(\_SB.PCI0.GFX0, DeviceObj)
    External(\_SB.PCI0.GFX0.ALSI)

iASL: Implemented support for multi-line error/warning messages. This 
enables more detailed and helpful error messages as below, from the 
initial deployment for the duplicate names error:

    DSDT.iiii   1692:       Device(PEG2) {
    Error    6074 -                  ^ Name already exists in scope 
(PEG2)

        Original name creation/declaration below:
        DSDT.iiii     93:   External(\_SB.PCI0.PEG2, DeviceObj)

AcpiXtract: Added additional flexibility to support differing input hex 
dump formats. Specifically, hex dumps that contain partial disassembly 
and/or comments within the ACPI table data definition. There exist some 
dump utilities seen in the field that create this type of hex dump (such 
as Simics). For example:

    DSDT @ 0xdfffd0c0 (10999 bytes)
        Signature DSDT
        Length 10999
        Revision 1
        Checksum 0xf3 (Ok)
        OEM_ID BXPC
        OEM_table_id BXDSDT
        OEM_revision 1
        Creator_id 1280593481
        Creator_revision 537399345
      0000: 44 53 44 54 f7 2a 00 00 01 f3 42 58 50 43 00 00
      ...
      2af0: 5f 4c 30 46 00 a4 01

Test suite: Miscellaneous changes/fixes:
    More cleanup and simplification of makefiles
    Continue compilation of test cases after a compile failure
    Do not perform binary compare unless both files actually exist

iASL: Performed some code/module restructuring. Moved all memory 
allocation functions to new modules. Two new files, aslallocate.c and 
aslcache.c

----------------------------------------
31 August 2017. Summary of changes for version 20170831:


1) ACPICA kernel-resident subsystem:

Implemented internal support for full 64-bit addresses that appear in all 
Generic Address Structure (GAS) structures. Previously, only the lower 32 
bits were used. Affects the use of GAS structures in the FADT and other 
tables, as well as the GAS structures passed to the AcpiRead and 
AcpiWrite public external interfaces that are used by drivers. Lv Zheng.

Added header support for the PDTT ACPI table (Processor Debug Trigger 
Table). Full support in the iASL Data Table Compiler and disassembler is 
forthcoming.


2) iASL Compiler/Disassembler and Tools:

iASL/Disassembler: Fixed a problem with the PPTT ACPI table (Processor 
Properties Topology Table) where a flag bit was specified in the wrong 
bit position ("Line Size Valid", bit 6).

iASL: Implemented support for Octal integer constants as defined by the 
ASL language grammar, per the ACPI specification. Any integer constant 
that starts with a zero is an octal constant. For example,
    Store (037777, Local0) /* Octal constant */
    Store (0x3FFF, Local0) /* Hex equivalent */
    Store (16383,  Local0) /* Decimal equivalent */

iASL: Improved overflow detection for 64-bit string conversions during 
compilation of integer constants. "Overflow" in this case means a string 
that represents an integer that is too large to fit into a 64-bit value. 
Any 64-bit constants within a 32-bit DSDT or SSDT are still truncated to 
the low-order 32 bits with a warning, as previously implemented. Several 
new exceptions are defined that indicate a 64-bit overflow, as well as 
the base (radix) that was used during the attempted conversion. Examples:
    Local0 = 0xAAAABBBBCCCCDDDDEEEEFFFF        // AE_HEX_OVERFLOW
    Local0 = 01111222233334444555566667777     // AE_OCTAL_OVERFLOW
    Local0 = 11112222333344445555666677778888  // AE_DECIMAL_OVERFLOW

iASL: Added a warning for the case where a ResourceTemplate is declared 
with no ResourceDescriptor entries (coded as "ResourceTemplate(){}"). In 
this case, the resulting template is created with a single END_TAG 
descriptor, which is essentially useless.

iASL: Expanded the -vw option (ignore specific warnings/remarks) to 
include compilation error codes as well.

----------------------------------------
28 July 2017. Summary of changes for version 20170728:


1) ACPICA kernel-resident subsystem:

Fixed a regression seen with small resource descriptors that could cause 
an inadvertent AE_AML_NO_RESOURCE_END_TAG exception.

AML interpreter: Implemented a new feature that allows forward references 
from individual named references within package objects that are 
contained within blocks of "module-level code". This provides 
compatibility with other ACPI implementations and supports existing 
firmware that depends on this feature. Example:

    Name (ABCD, 1)
    If (ABCD)                       /* An If() at module-level */
    {
        Name (PKG1, Package()
        {
            INT1                    /* Forward reference to object INT1 
*/
        })
        Name (INT1, 0x1234)
    }

AML Interpreter: Fixed a problem with the Alias() operator where aliases 
to some ASL objects were not handled properly. Objects affected are: 
Mutex, Event, and OperationRegion.

AML Debugger: Enhanced to properly handle AML Alias objects. These 
objects have one level of indirection which was not fully supported by 
the debugger.

Table Manager: Added support to detect and ignore duplicate SSDTs within 
the XSDT/RSDT. This error in the XSDT has been seen in the field.

EFI and EDK2 support:
    Enabled /WX flag for MSVC builds
    Added support for AcpiOsStall, AcpiOsSleep, and AcpiOsGetTimer
    Added local support for 64-bit multiply and shift operations
    Added support to compile acpidump.efi on Windows
    Added OSL function stubs for interfaces not used under EFI

Added additional support for the _DMA predefined name. _DMA returns a 
buffer containing a resource template. This change add support within the 
resource manager (AcpiWalkResourceBuffer) to walk and parse this list of 
resource descriptors. Lorenzo Pieralisi <lorenzo.pieralisi@arm.com>


2) iASL Compiler/Disassembler and Tools:

iASL: Fixed a problem where the internal input line buffer(s) could 
overflow if there are very long lines in the input ASL source code file. 
Implemented buffer management that automatically increases the size of 
the buffers as necessary.

iASL: Added an option (-vx) to "expect" particular remarks, warnings and 
errors. If the specified exception is not raised during compilation, the 
compiler emits an error. This is intended to support the ASL test suite, 
but may be useful in other contexts.

iASL: Implemented a new predefined macro, __METHOD__, which returns a 
string containing the name of the current control method that is being 
compiled.

iASL: Implemented debugger and table compiler support for the SDEI ACPI 
table (Software Delegated Exception Interface). James Morse 
<james.morse@arm.com>

Unix/Linux makefiles: Added an option to disable compile optimizations. 
The disable occurs when the NOOPT flag is set to TRUE. 
theracermaster@gmail.com

Acpidump: Added support for multiple DSDT and FACS tables. This can occur 
when there are different tables for 32-bit versus 64-bit.

Enhanced error reporting for the ASL test suite (ASLTS) by removing 
unnecessary/verbose text, and emit the actual line number where an error 
has occurred. These changes are intended to improve the usefulness of the 
test suite.

----------------------------------------
29 June 2017. Summary of changes for version 20170629:


1) ACPICA kernel-resident subsystem:

Tables: Implemented a deferred ACPI table verification. This is useful 
for operating systems where the tables cannot be verified in the early 
initialization stage due to early memory mapping limitations on some 
architectures. Lv Zheng.

Tables: Removed the signature validation for dynamically loaded tables. 
Provides compatibility with other ACPI implementations. Previously, only 
SSDT tables were allowed, as per the ACPI specification. Now, any table 
signature can be used via the Load() operator. Lv Zheng.

Tables: Fixed several mutex issues that could cause errors during table 
acquisition. Lv Zheng.

Tables: Fixed a problem where an ACPI warning could be generated if a 
null pointer was passed to the AcpiPutTable interface. Lv Zheng.

Tables: Added a mechanism to handle imbalances for the AcpiGetTable and 
AcpiPutTable interfaces. This applies to the "late stage" table loading 
when the use of AcpiPutTable is no longer required (since the system 
memory manager is fully running and available). Lv Zheng.

Fixed/Reverted a regression during processing of resource descriptors 
that contain only a single EndTag. Fixes an AE_AML_NO_RESOURCE_END_TAG 
exception in this case.

Headers: IORT/SMMU support: Updated the SMMU models for Revision C of the 
I/O Remapping specification. Robin Murphy <robin.murphy@arm.com>

Interpreter: Fixed a possible fault if an Alias operator with an invalid 
or duplicate target is encountered during Alias creation in 
AcpiExCreateAlias. Alex James <theracermaster@gmail.com>

Added an option to use designated initializers for function pointers. 
Kees Cook <keescook@google.com>


2) iASL Compiler/Disassembler and Tools:

iASL: Allow compilation of External declarations with target pathnames 
that refer to existing named objects within the table. Erik Schmauss.

iASL: Fixed a regression when compiling FieldUnits. Fixes an error if a 
FieldUnit name also is declared via External in the same table. Erik 
Schmauss.

iASL: Allow existing scope names within pathnames used in External 
statements. For example:
    External (ABCD.EFGH) // ABCD exists, but EFGH is truly external
    Device (ABCD)

iASL: IORT ACPI table: Implemented changes required to decode the new 
Proximity Domain for the SMMUv3 IORT. Disassembler and Data Table 
compiler. Ganapatrao Kulkarni <ganapatrao.kulkarni@cavium.com>

Disassembler: Don't abort disassembly on errors from External() 
statements. Erik Schmauss.

Disassembler: fixed a possible fault when one of the Create*Field 
operators references a Resource Template. ACPICA Bugzilla 1396.

iASL: In the source code, resolved some naming inconsistences across the 
parsing support. Fixes confusion between "Parse Op" and "Parse Node". 
Adds a new file, aslparseop.c

----------------------------------------
31 May 2017. Summary of changes for version 20170531:


0) ACPI 6.2 support:

The ACPI specification version 6.2 has been released and is available at
http://uefi.org/specifications

This version of ACPICA fully supports the ACPI 6.2 specification. Changes 
are summarized below.

New ACPI tables (Table Compiler/Disassembler/Templates):
    HMAT (Heterogeneous Memory Attributes Table)
    WSMT (Windows SMM Security Mitigation Table)
    PPTT (Processor Properties Topology Table)

New subtables for existing ACPI tables:
    HEST (New subtable, Arch-deferred machine check)
    SRAT (New subtable, Arch-specific affinity structure)
    PCCT (New subtables, Extended PCC subspaces (types 3 and 4))

Simple updates for existing ACPI tables:
    BGRT (two new flag bits)
    HEST (New bit defined for several subtables, GHES_ASSIST)

New Resource Descriptors and Resource macros (Compiler/Disassembler):
    PinConfig()
    PinFunction()
    PinGroup()
    PinGroupConfig()
    PinGroupFunction()
    New type for hardware error notification (section 18.3.2.9)

New predefined names/methods (Compiler/Interpreter):
    _HMA (Heterogeneous Memory Attributes)
    _LSI (Label Storage Information)
    _LSR (Label Storage Read)
    _LSW (Label Storage Write)

ASL grammar/macro changes (Compiler):
    For() ASL macro, implemented with the AML while operator
    Extensions to Concatenate operator
    Support for multiple definition blocks in same ASL file
    Clarification for Buffer operator
    Allow executable AML code underneath all scopes (Devices, etc.)
    Clarification/change for the _OSI return value
    ASL grammar update for reference operators
    Allow a zero-length string for AML filename in DefinitionBlock

Miscellaneous:
    New device object notification value
    Remove a notify value (0x0C) for graceful shutdown
    New UUIDs for processor/cache properties and
        physical package property
    New _HID, ACPI0014 (Wireless Power Calibration Device)


1) ACPICA kernel-resident subsystem:

Added support to disable ACPI events on hardware-reduced platforms. 
Eliminates error messages of the form "Could not enable fixed event". Lv 
Zheng

Fixed a problem using Device/Thermal objects with the ObjectType and 
DerefOf ASL operators. This support had not been fully/properly 
implemented.

Fixed a problem where if a Buffer object containing a resource template 
was longer than the actual resource template, an error was generated -- 
even though the AML is legal. This case has been seen in the field.

Fixed a problem with the header definition of the MADT PCAT_COMPAT flag. 
The values for DUAL_PIC and MULTIPLE_APIC were reversed.

Added header file changes for the TPM2 ACPI table. Update to new version 
of the TCG specification. Adds a new TPM2 subtable for ARM SMC.

Exported the external interfaces AcpiAcquireMutex and AcpiReleaseMutex. 
These interfaces are intended to be used only in conjunction with the 
predefined _DLM method (Device Lock Method). "This object appears in a 
device scope when AML access to the device must be synchronized with the 
OS environment".

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a much larger code and data size.

  Current Release:
    Non-Debug Version: 143.1K Code, 60.0K Data, 203.1K Total
    Debug Version:     204.0K Code, 84.3K Data, 288.3K Total
  Previous Release:
    Non-Debug Version: 141.7K Code, 58.5K Data, 200.2K Total
    Debug Version:     207.5K Code, 82.7K Data, 290.2K Total


2) iASL Compiler/Disassembler and Tools:

iASL: Fixed a problem where an External() declaration could not refer to 
a Field Unit. Erik Schmauss.

Disassembler: Improved support for the Switch/Case operators. This 
feature will disassemble AML code back to the original Switch operators 
when possible, instead of an If..Else sequence. David Box

iASL and disassembler: Improved the handling of multiple extraneous 
parentheses for both ASL input and disassembled ASL output.

Improved the behavior of the iASL compiler and disassembler to detect 
improper use of external declarations

Disassembler: Now aborts immediately upon detection of an unknown AML 
opcode. The AML parser has no real way to recover from this, and can 
result in the creation of an ill-formed parse tree that causes errors 
later during the disassembly.

All tools: Fixed a problem where the Unix application OSL did not handle 
control-c correctly. For example, a control-c could incorrectly wake the 
debugger.

AcpiExec: Improved the Control-C handling and added a handler for 
segmentation faults (SIGSEGV). Supports both Windows and Unix-like 
environments.

Reduced the verbosity of the generic unix makefiles. Previously, each 
compilation displayed the full set of compiler options. This has been 
eliminated as the options are easily inspected within the makefiles. Each 
compilation now results in a single line of output.

----------------------------------------
03 March 2017. Summary of changes for version 20170303:


0) ACPICA licensing:

The licensing information at the start of each source code module has 
been updated. In addition to the Intel license, the dual GPLv2/BSD 
license has been added for completeness. Now, a single version of the 
source code should be suitable for all ACPICA customers. This is the 
major change for this release since it affects all source code modules.


1) ACPICA kernel-resident subsystem: 

Fixed two issues with the common asltypes.h header that could cause 
problems in some environments: (Kim Jung-uk)
    Removed typedef for YY_BUFFER_STATE ?
       Fixes an error with earlier versions of Flex.
    Removed use of FILE typedef (which is only defined in stdio.h)


2) iASL Compiler/Disassembler and Tools: 

Disassembler: fixed a regression introduced in 20170224. A fix for a 
memory leak related to resource descriptor tags (names) could fault when 
the disassembler was generated with 64-bit compilers.

The ASLTS test suite has been updated to implement a new testing 
architecture. During generation of the suite from ASL source, both the 
ASL and ASL+ compilers are now validated, as well as the disassembler 
itself (Erik Schmauss). The architecture executes as follows:

    For every ASL source module:
        Compile (legacy ASL compilation)
        Disassemble the resulting AML to ASL+ source code
        Compile the new ASL+ module
        Perform a binary compare on the legacy AML and the new ASL+ AML
    The ASLTS suite then executes normally using the AML binaries.

----------------------------------------
24 February 2017. Summary of changes for version 20170224:


1) ACPICA kernel-resident subsystem:

Interpreter: Fixed two issues with the control method return value auto-
repair feature, where an attempt to double-delete an internal object 
could result in an ACPICA warning (for _CID repair and others). No fault 
occurs, however, because the attempted deletion (actually a release to an 
internal cache) is detected and ignored via object poisoning.

Debugger: Fixed an AML interpreter mutex issue during the single stepping 
of control methods. If certain debugger commands are executed during 
stepping, a mutex aquire/release error could occur. Lv Zheng.

Fixed some issues generating ACPICA with the Intel C compiler by 
restoring the original behavior and compiler-specific include file in 
acenv.h. Lv Zheng.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a much larger code and data size.

  Current Release:
    Non-Debug Version: 141.7K Code, 58.5K Data, 200.2K Total
    Debug Version:     207.5K Code, 82.7K Data, 290.2K Total
  Previous Release:
    Non-Debug Version: 137.4K Code, 52.6K Data, 190.0K Total
    Debug Version:     201.5K Code, 82.2K Data, 283.7K Total


2) iASL Compiler/Disassembler and Tools:

iASL/Disassembler: A preliminary version of a new ASL-to-ASL+ conversion 
tool has been designed, implemented, and included in this release. The 
key feature of this utility is that the original comments within the 
input ASL file are preserved during the conversion process, and included 
within the converted ASL+ file -- thus creating a transparent conversion 
of existing ASL files to ASL+ (ASL 2.0). Erik Schmauss.

    Usage: iasl -ca <ASL-filename>  // Output is a .dsl file with 
converted code

iASL/Disassembler: Improved the detection and correct disassembly of 
Switch/Case operators. This feature detects sequences of if/elseif/else 
operators that originated from ASL Switch/Case/Default operators and 
emits the original operators. David Box.

iASL: Improved the IORT ACPI table support in the following areas. Lv 
Zheng:
    Clear MappingOffset if the MappingCount is zero.
    Fix the disassembly of the SMMU GSU interrupt offset.
    Update the template file for the IORT table.

Disassembler: Enhanced the detection and disassembly of resource 
template/descriptor within a Buffer object. An EndTag descriptor is now 
required to have a zero second byte, since all known ASL compilers emit 
this. This helps eliminate incorrect decisions when a buffer is 
disassembled (false positives on resource templates).

----------------------------------------
19 January 2017. Summary of changes for version 20170119:


1) General ACPICA software:

Entire source code base: Added the 2017 copyright to all source code 
legal/licensing module headers and utility/tool signons. This includes 
the standard Linux dual-license header. This affects virtually every file 
in the ACPICA core subsystem, iASL compiler, all ACPICA utilities, and 
the ACPICA test suite.


2) iASL Compiler/Disassembler and Tools:

iASL: Removed/fixed an inadvertent remark when a method argument 
containing a reference is used as a target operand within the method (and 
never used as a simple argument), as in the example below. Jeffrey Hugo.

    dsdt.asl   1507:    Store(0x1, Arg0)
    Remark   2146 -                ^ Method Argument is never used (Arg0)

All tools: Removed the bit width of the compiler that generated the tool 
from the common signon for all user space tools. This proved to be 
confusing and unnecessary. This includes similar removal of HARDWARE_NAME 
from the generic makefiles (Thomas Petazzoni). Example below.

    Old:
    ASL+ Optimizing Compiler version 20170119-32
    ASL+ Optimizing Compiler version 20170119-64

    New:
    ASL+ Optimizing Compiler version 20170119

----------------------------------------
22 December 2016. Summary of changes for version 20161222:


1) ACPICA kernel-resident subsystem:

AML Debugger: Implemented a new mechanism to simplify and enhance 
debugger integration into all environments, including kernel debuggers 
and user-space utilities, as well as remote debug services. This 
mechanism essentially consists of new OSL interfaces to support debugger 
initialization/termination, as well as wait/notify interfaces to perform 
the debugger handshake with the host. Lv Zheng.

    New OSL interfaces:
        AcpiOsInitializeDebugger (void)
        AcpiOsTerminateDebugger (void)
        AcpiOsWaitCommandReady (void)
        AcpiOsNotifyCommandComplete (void)

    New OS services layer:
        osgendbg.c -- Example implementation, and used for AcpiExec

Update for Generic Address Space (GAS) support: Although the AccessWidth 
and/or BitOffset fields of the GAS are not often used, this change now 
fully supports these fields. This affects the internal support for FADT 
registers, registers in other ACPI data tables, and the AcpiRead and 
AcpiWrite public interfaces. Lv Zheng.

Sleep support: In order to simplify integration of ACPI sleep for the 
various host operating systems, a new OSL interface has been introduced. 
AcpiOsEnterSleep allows the host to perform any required operations 
before the final write to the sleep control register(s) is performed by 
ACPICA. Lv Zheng.

    New OSL interface:
        AcpiOsEnterSleep(SleepState, RegisterAValue, RegisterBValue)

    Called from these internal interfaces:
        AcpiHwLegacySleep
        AcpiHwExtendedSleep

EFI support: Added a very small EFI/ACPICA example application. Provides 
a simple demo for EFI integration, as well as assisting with resolution 
of issues related to customer ACPICA/EFI integration. Lv Zheng. See:

    source/tools/efihello/efihello.c

Local C library: Implemented several new functions to enhance ACPICA 
portability, for environments where these clib functions are not 
available (such as EFI). Lv Zheng:
    putchar
    getchar
    strpbrk
    strtok
    memmove

Fixed a regression where occasionally a valid resource descriptor was 
incorrectly detected as invalid at runtime, and a 
AE_AML_NO_RESOURCE_END_TAG was returned.

Fixed a problem with the recently implemented support that enables 
control method invocations as Target operands to many ASL operators. 
Warnings of this form: "Needed type [Reference], found [Processor]" were 
seen at runtime for some method invocations.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a much larger code and data size.

  Current Release:
    Non-Debug Version: 141.5K Code, 58.5K Data, 200.0K Total
    Debug Version:     201.7K Code, 82.7K Data, 284.4K Total
  Previous Release:
    Non-Debug Version: 140.5K Code, 58.5K Data, 198.9K Total
    Debug Version:     201.3K Code, 82.7K Data, 284.0K Total


2) iASL Compiler/Disassembler and Tools:

Disassembler: Enhanced output by adding the capability to detect and 
disassemble ASL Switch/Case statements back to the original ASL source 
code instead of if/else blocks. David Box.

AcpiHelp: Split a large file into separate files based upon 
functionality/purpose. New files are:
    ahaml.c
    ahasl.c

----------------------------------------
17 November 2016. Summary of changes for version 20161117:


1) ACPICA kernel-resident subsystem:

Table Manager: Fixed a regression introduced in 20160729, "FADT support 
cleanup". This was an attempt to remove all references in the source to 
the FADT version 2, which never was a legal version number. It was 
skipped because it was an early version of 64-bit support that was 
eventually abandoned for the current 64-bit support.

Interpreter: Fixed a problem where runtime implicit conversion was 
incorrectly disabled for the ASL operators below. This brings the 
behavior into compliance with the ACPI specification:
    FromBCD
    ToBCD
    ToDecimalString
    ToHexString
    ToInteger
    ToBuffer

Table Manager: Added a new public interface, AcpiPutTable, used to 
release and free an ACPI table returned by AcpiGetTable and related 
interfaces. Lv Zheng.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a much larger code and data size.

  Current Release:
    Non-Debug Version: 140.5K Code, 58.5K Data, 198.9K Total
    Debug Version:     201.3K Code, 82.7K Data, 284.0K Total
  Previous Release:
    Non-Debug Version: 140.4K Code, 58.1K Data, 198.5K Total
    Debug Version:     200.7K Code, 82.1K Data, 282.8K Total


2) iASL Compiler/Disassembler and Tools:

Disassembler: Fixed a regression for disassembly of Resource Template. 
Detection of templates in the AML stream missed some types of templates.

iASL: Fixed a problem where an Access Size error was returned for the PCC 
address space when the AccessSize of the GAS register is greater than a 
DWORD. Hoan Tran.

iASL: Implemented several grammar changes for the operators below. These 
changes are slated for the next version of the ACPI specification:
    RefOf        - Disallow method invocation as an operand
    CondRefOf    - Disallow method invocation as an operand
    DerefOf      - Disallow operands that use the result from operators 
that
                   do not return a reference (Changed TermArg to 
SuperName).

iASL: Control method invocations are now allowed for Target operands, as 
per the ACPI specification. Removed error for using a control method 
invocation as a Target operand.

Disassembler: Improved detection of Resource Templates, Unicode, and 
Strings within Buffer objects. These subtypes do not contain a specific 
opcode to indicate the originating ASL code, and they must be detected by 
other means within the disassembler. 

iASL: Implemented an optimization improvement for 32-bit ACPI tables 
(DSDT/SSDT). For the 32-bit case only, compute the optimum integer opcode 
only after 64-bit to 32-bit truncation. A truncation warning message is 
still emitted, however.

AcpiXtract: Implemented handling for both types of line terminators (LF 
or CR/LF) so that it can accept AcpiDump output files from any system. 
Peter Wu.

AcpiBin: Added two new options for comparing AML files:
    -a: compare and display ALL mismatches
    -o: start compare at this offset into the second file

----------------------------------------
30 September 2016. Summary of changes for version 20160930:


1) ACPICA kernel-resident subsystem:

Fixed a regression in the internal AcpiTbFindTable function where a non 
AE_OK exception could inadvertently be returned even if the function did 
not fail. This problem affects the following operators:
    DataTableRegion
    LoadTable

Fixed a regression in the LoadTable operator where a load to any 
namespace location other than the root no longer worked properly.

Increased the maximum loop count value that will result in the 
AE_AML_INFINITE_LOOP exception. This is a mechanism that is intended to 
prevent infinite loops within the AML interpreter and thus the host OS 
kernel. The value is increased from 0xFFFF to 0xFFFFF loops (65,535 to 
1,048,575).

Moved the AcpiGbl_MaxLoopIterations configuration variable to the public 
acpixf.h file. This allows hosts to easily configure the maximum loop 
count at runtime.

Removed an illegal character in the strtoul64.c file. This character 
caused errors with some C compilers.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a much larger code and data size.

  Current Release:
    Non-Debug Version: 140.4K Code, 58.1K Data, 198.5K Total
    Debug Version:     200.7K Code, 82.1K Data, 282.8K Total
  Previous Release:
    Non-Debug Version: 140.0K Code, 58.1K Data, 198.1K Total
    Debug Version:     200.3K Code, 82.1K Data, 282.4K Total


2) iASL Compiler/Disassembler and Tools:

Disassembler: Fixed a problem with the conversion of Else{If{ blocks into 
the simpler ASL ElseIf keyword. During the conversion, a trailing If 
block could be lost and missing from the disassembled output.

iASL: Fixed a missing parser rule for the ObjectType operator. For ASL+, 
the missing rule caused a parse error when using the Index operator as an 
operand to ObjectType. This construct now compiles properly. Example:
    ObjectType(PKG1[4]).

iASL: Correctly handle unresolved symbols in the hardware map file (-lm 
option). Previously, unresolved symbols could cause a protection fault. 
Such symbols are now marked as unresolved in the map file.

iASL: Implemented support to allow control method invocations as an 
operand to the ASL DeRefOf operator. Example:
    DeRefOf(MTH1(Local0))

Disassembler: Improved support for the ToPLD ASL macro. Detection of a 
possible _PLD buffer now includes examination of both the normal buffer 
length (16 or 20) as well as the surrounding AML package length.

Disassembler: Fixed a problem with the decoding of complex expressions 
within the Divide operator for ASL+. For the case where both the quotient 
and remainder targets are specified, the entire statement cannot be 
disassembled. Previously, the output incorrectly contained a mix of ASL- 
and ASL+ operators. This mixed statement causes a syntax error when 
compiled. Example:
    Divide (Add (INT1, 6), 128, RSLT, QUOT)  // was incorrectly 
disassembled to:
    Divide (INT1 + 6, 128, RSLT, QUOT)

iASL/Tools: Added support to process AML and non-AML ACPI tables 
consistently. For the disassembler and AcpiExec, allow all types of ACPI 
tables (AML and data tables). For the iASL -e option, allow only AML 
tables (DSDT/SSDT).

----------------------------------------
31 August 2016. Summary of changes for version 20160831:


1) ACPICA kernel-resident subsystem:

Improve support for the so-called "module-level code", which is defined 
to be math, logical and control AML opcodes that appear outside of any 
control method. This change improves the support by adding more opcodes 
that can be executed in the manner. Some other issues have been solved, 
and the ASL grammar changes to support such code under all scope 
operators (Device, etc.) are complete. Lv Zheng.

UEFI support: these OSL functions have been implemented. This is an 
additional step toward supporting the AcpiExec utility natively (with 
full hardware access) under UEFI. Marcelo Ferreira.
    AcpiOsReadPciConfiguration
    AcpiOsWritePciConfiguration

Fixed a possible mutex error during control method auto-serialization. Lv 
Zheng. 

Updated support for the Generic Address Structure by fully implementing 
all GAS fields when a 32-bit address is expanded to a 64-bit GAS. Lv 
Zheng.

Updated the return value for the internal _OSI method. Instead of 
0xFFFFFFFF, the "Ones" value is now returned, which is 0xFFFFFFFFFFFFFFFF 
for 64-bit ACPI tables. This fixes an incompatibility with other ACPI 
implementations, and will be reflected and clarified in the next version 
of the ACPI specification.

Implemented two new table events that can be passed to an ACPICA table 
handler. These events are used to indicate a table installation or 
uninstallation. These events are used in addition to existed table load 
and unload events. Lv Zheng.

Implemented a cleanup for all internal string-to-integer conversions. 
Consolidate multiple versions of this functionality and limit possible 
bases to either 10 or 16 to simplify the code. Adds a new file, 
utstrtoul64.

Cleanup the inclusion order of the various compiler-specific headers. 
This simplifies build configuration management. The compiler-specific 
headers are now split out from the host-specific headers. Lv Zheng.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a much larger code and data size.

  Current Release:
    Non-Debug Version: 140.1K Code, 58.1K Data, 198.1K Total
    Debug Version:     200.3K Code, 82.1K Data, 282.4K Total


2) iASL Compiler/Disassembler and Tools:

iASL/AcpiExec: Added a command line option to display the build date/time 
of the tool (-vd). This can be useful to verify that the correct version 
of the tools are being used.

AML Debugger: Implemented a new subcommand ("execute predef") to execute 
all predefined control methods and names within the current namespace. 
This can be useful for debugging problems with ACPI tables and the ACPI 
namespace.

----------------------------------------
29 July 2016. Summary of changes for version 20160729:


1) ACPICA kernel-resident subsystem:

Implemented basic UEFI support for the various ACPICA tools. This 
includes:
1) An OSL to implement the various AcpiOs* interfaces on UEFI.
2) Support to obtain the ACPI tables on UEFI.
3) Local implementation of required C library functions not available on 
UEFI.
4) A front-end (main) function for the tools for UEFI-related 
initialization.

The initial deployment of this support is the AcpiDump utility executing 
as an UEFI application via EDK2 (EDKII, "UEFI Firmware Development Kit"). 
Current environments supported are Linux/Unix. MSVC generation is not 
supported at this time. See the generate/efi/README file for build 
instructions. Lv Zheng.

Future plans include porting the AcpiExec utility to execute natively on 
the platform with I/O and memory access. This will allow viewing/dump of 
the platform namespace and native execution of ACPI control methods that 
access the actual hardware. To fully implement this support, the OSL 
functions below must be implemented with UEFI interfaces. Any community 
help in the implementation of these functions would be appreciated:
    AcpiOsReadPort
    AcpiOsWritePort
    AcpiOsReadMemory
    AcpiOsWriteMemory
    AcpiOsReadPciConfiguration
    AcpiOsWritePciConfiguration

Restructured and standardized the C library configuration for ACPICA, 
resulting in the various configuration options below. This includes a 
global restructuring of the compiler-dependent and platform-dependent 
include files. These changes may affect the existing platform-dependent 
configuration files on some hosts. Lv Zheng. 

The current C library configuration options appear below. For any issues, 
it may be helpful to examine the existing compiler-dependent and 
platform-dependent files as examples. Lv Zheng. 

1) Linux kernel:
    ACPI_USE_STANDARD_HEADERS=n in order not to use system-provided C 
library.
    ACPI_USE_SYSTEM_CLIBRARY=y in order not to use ACPICA mini C library.
2) Unix/Windows/BSD applications:
    ACPI_USE_STANDARD_HEADERS=y in order to use system-provided C 
library.
    ACPI_USE_SYSTEM_CLIBRARY=y in order not to use ACPICA mini C library.
3) UEFI applications:
    ACPI_USE_STANDARD_HEADERS=n in order not to use system-provided C 
library.
    ACPI_USE_SYSTEM_CLIBRARY=n in order to use ACPICA mini C library.
4) UEFI applications (EDK2/StdLib):
    ACPI_USE_STANDARD_HEADERS=y in order to use EDK2 StdLib C library.
    ACPI_USE_SYSTEM_CLIBRARY=y in order to use EDK2 StdLib C library.


AML interpreter: "module-level code" support. Allows for execution of so-
called "executable" AML code (math/logical operations, etc.) outside of 
control methods not just at the module level (top level) but also within 
any scope declared outside of a control method - Scope{}, Device{}, 
Processor{}, PowerResource{}, and ThermalZone{}. Lv Zheng. 

Simplified the configuration of the "maximum AML loops" global option by 
adding a global public variable, "AcpiGbl_MaxLoopIterations" which can be 
modified at runtime.


Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a much larger code and data size.

  Current Release:
    Non-Debug Version: 139.1K Code, 22.9K Data, 162.0K Total
    Debug Version:     199.0K Code, 81.8K Data, 280.8K Total


2) iASL Compiler/Disassembler and Tools:

iASL: Add full support for the RASF ACPI table (RAS Features Table). 
Includes disassembler, data table compiler, and header support.

iASL Expand "module-level code" support. Allows for 
compilation/disassembly of so-called "executable" AML code (math/logical 
operations, etc.) outside of control methods not just at the module level 
(top level) but also within any scope declared outside of a control 
method - Scope{}, Device{}, Processor{}, PowerResource{}, and 
ThermalZone{}.

AcpiDump: Added support for dumping all SSDTs on newer versions of 
Windows. These tables are now easily available -- SSDTs are not available 
through the registry on older versions.

----------------------------------------
27 May 2016. Summary of changes for version 20160527:


1) ACPICA kernel-resident subsystem:

Temporarily reverted the new arbitrary bit length/alignment support in 
AcpiHwRead/AcpiHwWrite for the Generic Address Structure. There have been 
a number of regressions with the new code that need to be fully resolved 
and tested before this support can be finally integrated into ACPICA. 
Apologies for any inconveniences these issues may have caused.

The ACPI message macros are not configurable (ACPI_MSG_ERROR, 
ACPI_MSG_EXCEPTION, ACPI_MSG_WARNING, ACPI_MSG_INFO, ACPI_MSG_BIOS_ERROR, 
and ACPI_MSG_BIOS_WARNING). Lv Zheng.

Fixed a couple of GCC warnings associated with the use of the -Wcast-qual 
option. Adds a new return macro, return_STR. Junk-uk Kim.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a much larger code and data size.

----------------------------------------
22 April 2016. Summary of changes for version 20160422:

1) ACPICA kernel-resident subsystem:

Fixed a regression in the GAS (generic address structure) arbitrary bit 
support in AcpiHwRead/AcpiHwWrite. Problem could cause incorrect behavior 
and incorrect return values. Lv Zheng. ACPICA BZ 1270.

ACPI 6.0: Added support for new/renamed resource macros. One new argument 
was added to each of these macros, and the original name has been 
deprecated. The AML disassembler will always disassemble to the new 
names. Support for the new macros was added to iASL, disassembler, 
resource manager, and the acpihelp utility. ACPICA BZ 1274.

    I2cSerialBus  -> I2cSerialBusV2
    SpiSerialBus  -> SpiSerialBusV2
    UartSerialBus -> UartSerialBusV2

ACPI 6.0: Added support for a new integer field that was appended to the 
package object returned by the _BIX method. This adds iASL compile-time 
and AML runtime error checking. ACPICA BZ 1273.

ACPI 6.1: Added support for a new PCCT subtable, "HW-Reduced Comm 
Subspace Type2" (Headers, Disassembler, and data table compiler).

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a much larger code and data size.

  Current Release:
    Non-Debug Version: 137.4K Code, 52.6K Data, 190.0K Total
    Debug Version:     201.5K Code, 82.2K Data, 283.7K Total
  Previous Release:
    Non-Debug Version: 137.1K Code, 51.5K Data, 188.6K Total
    Debug Version:     201.0K Code, 82.0K Data, 283.0K Total


2) iASL Compiler/Disassembler and Tools:

iASL: Implemented an ASL grammar extension to allow/enable executable 
"module-level code" to be created and executed under the various 
operators that create new scopes. This type of AML code is already 
supported in all known AML interpreters, and the grammar change will 
appear in the next version of the ACPI specification. Simplifies the 
conditional runtime creation of named objects under these object types: 

    Device
    PowerResource
    Processor
    Scope
    ThermalZone

iASL: Implemented a new ASL extension, a "For" loop macro to add greater 
ease-of-use to the ASL language. The syntax is similar to the 
corresponding C operator, and is implemented with the existing AML While 
opcode -- thus requiring no changes to existing AML interpreters.

    For (Initialize, Predicate, Update) {TermList}

Grammar:
    ForTerm :=
        For (
            Initializer    // Nothing | TermArg => ComputationalData
            Predicate      // Nothing | TermArg => ComputationalData
            Update         // Nothing | TermArg => ComputationalData
        ) {TermList}


iASL: The _HID/_ADR detection and validation has been enhanced to search 
under conditionals in order to allow these objects to be conditionally 
created at runtime.

iASL: Fixed several issues with the constant folding feature. The 
improvement allows better detection and resolution of statements that can 
be folded at compile time. ACPICA BZ 1266. 

iASL/Disassembler: Fixed a couple issues with the Else{If{}...} 
conversion to the ASL ElseIf operator where incorrect ASL code could be 
generated.

iASL/Disassembler: Fixed a problem with the ASL+ code disassembly where 
sometimes an extra (and extraneous) set of parentheses were emitted for 
some combinations of operators. Although this did not cause any problems 
with recompilation of the disassembled code, it made the code more 
difficult to read. David Box. ACPICA BZ 1231.

iASL: Changed to ignore the unreferenced detection for predefined names 
of resource descriptor elements, when the resource descriptor is 
created/defined within a control method.

iASL: Disassembler: Fix a possible fault with externally declared Buffer 
objects.

----------------------------------------
18 March 2016. Summary of changes for version 20160318:

1) ACPICA kernel-resident subsystem:

Added support for arbitrary bit lengths and bit offsets for registers 
defined by the Generic Address Structure. Previously, only aligned bit 
lengths of 8/16/32/64 were supported. This was sufficient for many years, 
but recently some machines have been seen that require arbitrary bit-
level support. ACPICA BZ 1240. Lv Zheng.

Fixed an issue where the \_SB._INI method sometimes must be evaluated 
before any _REG methods are evaluated. Lv Zheng.

Implemented several changes related to ACPI table support 
(Headers/Disassembler/TableCompiler):
NFIT: For ACPI 6.1, updated to add some additional new fields and 
constants.
FADT: Updated a warning message and set compliance to ACPI 6.1 (Version 
6).
DMAR: Added new constants per the 10/2014 DMAR spec.
IORT: Added new subtable per the 10/2015 IORT spec.
HEST: For ACPI 6.1, added new constants and new subtable.
DBG2: Added new constants per the 12/2015 DBG2 spec.
FPDT: Fixed several incorrect fields, add the FPDT boot record structure. 
ACPICA BZ 1249.
ERST/EINJ: Updated disassembler with new "Execute Timings" actions.

Updated header support for the DMAR table to match the current version of 
the related spec.

Added extensions to the ASL Concatenate operator to allow any ACPI object 
to be passed as an operand. Any object other than Integer/String/Buffer 
simply returns a string containing the object type. This extends the 
usefulness of the Printf macros. Previously, Concatenate would abort the 
control method if a non-data object was encountered.

ACPICA source code: Deployed the C "const" keyword across the source code 
where appropriate. ACPICA BZ 732. Joerg Sonnenberger (NetBSD).

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a much larger code and data size.

  Current Release:
    Non-Debug Version: 137.1K Code, 51.5K Data, 188.6K Total
    Debug Version:     201.0K Code, 82.0K Data, 283.0K Total
  Previous Release:
    Non-Debug Version: 136.2K Code, 51.5K Data, 187.7K Total
    Debug Version:     200.4K Code, 82.0K Data, 282.4K Total


2) iASL Compiler/Disassembler and Tools:

iASL/Disassembler: Improved the heuristic used to determine the number of 
arguments for an externally defined control method (a method in another 
table). Although this is an improvement, there is no deterministic way to 
"guess" the number of method arguments. Only the ACPI 6.0 External opcode 
will completely solve this problem as it is deployed (automatically) in 
newer BIOS code.

iASL/Disassembler: Fixed an ordering issue for emitted External() ASL 
statements that could cause errors when the disassembled file is 
compiled. ACPICA BZ 1243. David Box.

iASL: Fixed a regression caused by the merger of the two versions of the 
local strtoul64. Because of a dependency on a global variable, strtoul64 
could return an error for integers greater than a 32-bit value. ACPICA BZ 
1260.

iASL: Fixed a regression where a fault could occur for an ASL Return 
statement if it invokes a control method that is not resolved. ACPICA BZ 
1264.

AcpiXtract: Improved input file validation: detection of binary files and 
non-acpidump text files.

----------------------------------------
12 February 2016. Summary of changes for version 20160212:

1) ACPICA kernel-resident subsystem:

Implemented full support for the ACPI 6.1 specification (released in 
January). This version of the specification is available at:  
http://www.uefi.org/specifications

Only a relatively small number of changes were required in ACPICA to 
support ACPI 6.1, in these areas:
- New predefined names
- New _HID values
- A new subtable for HEST
- A few other header changes for new values

Ensure \_SB_._INI is executed before any _REG methods are executed. There 
appears to be existing BIOS code that relies on this behavior. Lv Zheng.

Reverted a change made in version 20151218 which enabled method 
invocations to be targets of various ASL operators (SuperName and Target 
grammar elements). While the new behavior is supported by the ACPI 
specification, other AML interpreters do not support this behavior and 
never will. The ACPI specification will be updated for ACPI 6.2 to remove 
this support. Therefore, the change was reverted to the original ACPICA 
behavior.

ACPICA now supports the GCC 6 compiler.

Current Release: (Note: build changes increased sizes)
    Non-Debug Version: 136.2K Code, 51.5K Data, 187.7K Total
    Debug Version:     200.4K Code, 82.0K Data, 282.4K Total
Previous Release:
    Non-Debug Version: 102.7K Code, 28.4K Data, 131.1K Total
    Debug Version:     200.4K Code, 81.9K Data, 282.3K Total


2) iASL Compiler/Disassembler and Tools:

Completed full support for the ACPI 6.0 External() AML opcode. The 
compiler emits an external AML opcode for each ASL External statement. 
This opcode is used by the disassembler to assist with the disassembly of 
external control methods by specifying the required number of arguments 
for the method. AML interpreters do not use this opcode. To ensure that 
interpreters do not even see the opcode, a block of one or more external 
opcodes is surrounded by an "If(0)" construct. As this feature becomes 
commonly deployed in BIOS code, the ability of disassemblers to correctly 
disassemble AML code will be greatly improved. David Box.

iASL: Implemented support for an optional cross-reference output file. 
The -lx option will create a the cross-reference file with the suffix 
"xrf". Three different types of cross-reference are created in this file:
- List of object references made from within each control method
- Invocation (caller) list for each user-defined control method
- List of references to each non-method object in the namespace

iASL: Method invocations as ASL Target operands are now disallowed and 
flagged as errors in preparation for ACPI 6.2 (see the description of the 
problem above).

----------------------------------------
8 January 2016. Summary of changes for version 20160108:

1) ACPICA kernel-resident subsystem:

Updated all ACPICA copyrights and signons to 2016: Added the 2016 
copyright to all source code module headers and utility/tool signons. 
This includes the standard Linux dual-license header. This affects 
virtually every file in the ACPICA core subsystem, iASL compiler, all 
ACPICA utilities, and the ACPICA test suite.

Fixed a regression introduced in version 20151218 concerning the 
execution of so-called module-level ASL/AML code. Namespace objects 
created under a module-level If() construct were not properly/fully 
entered into the namespace and could cause an interpreter fault when 
accessed.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a much larger code and data size.

Current Release:
    Non-Debug Version: 102.7K Code, 28.4K Data, 131.1K Total
    Debug Version:     200.4K Code, 81.9K Data, 282.4K Total
  Previous Release:
    Non-Debug Version: 102.6K Code, 28.4K Data, 131.0K Total
    Debug Version:     200.3K Code, 81.9K Data, 282.3K Total


2) iASL Compiler/Disassembler and Tools:

Fixed a problem with the compilation of the GpioIo and GpioInt resource 
descriptors. The _PIN field name was incorrectly defined to be an array 
of 32-bit values, but the _PIN values are in fact 16 bits each. This 
would cause incorrect bit width warnings when using Word (16-bit) fields 
to access the descriptors.


----------------------------------------
18 December 2015. Summary of changes for version 20151218:

1) ACPICA kernel-resident subsystem:

Implemented per-AML-table execution of "module-level code" as individual 
ACPI tables are loaded into the namespace during ACPICA initialization. 
In other words, any module-level code within an AML table is executed 
immediately after the table is loaded, instead of batched and executed 
after all of the tables have been loaded. This provides compatibility 
with other ACPI implementations. ACPICA BZ 1219. Bob Moore, Lv Zheng, 
David Box.

To fully support the feature above, the default operation region handlers 
for the SystemMemory, SystemIO, and PCI_Config address spaces are now 
installed before any ACPI tables are loaded. This enables module-level 
code to access these address spaces during the table load and module-
level code execution phase. ACPICA BZ 1220. Bob Moore, Lv Zheng, David 
Box.

Implemented several changes to the internal _REG support in conjunction 
with the changes above. Also, changes to the AcpiExec/AcpiNames/Examples 
utilities for the changes above. Although these tools were changed, host 
operating systems that simply use the default handlers for SystemMemory, 
SystemIO, and PCI_Config spaces should not require any update. Lv Zheng.

For example, in the code below, DEV1 is conditionally added to the 
namespace by the DSDT via module-level code that accesses an operation 
region. The SSDT references DEV1 via the Scope operator. DEV1 must be 
created immediately after the DSDT is loaded in order for the SSDT to 
successfully reference DEV1. Previously, this code would cause an 
AE_NOT_EXIST exception during the load of the SSDT. Now, this code is 
fully supported by ACPICA.

    DefinitionBlock ("", "DSDT", 2, "Intel", "DSDT1", 1)
    {
        OperationRegion (OPR1, SystemMemory, 0x400, 32)
        Field (OPR1, AnyAcc, NoLock, Preserve)
        {
            FLD1, 1
        }
        If (FLD1)
        {
            Device (\DEV1)
            {
            }
        }
    }
    DefinitionBlock ("", "SSDT", 2, "Intel", "SSDT1", 1)
    {
        External (\DEV1, DeviceObj)
        Scope (\DEV1)
        {
        }
    }

Fixed an AML interpreter problem where control method invocations were 
not handled correctly when the invocation was itself a SuperName argument 
to another ASL operator. In these cases, the method was not invoked. 
ACPICA BZ 1002. Affects the following ASL operators that have a SuperName 
argument:
    Store
    Acquire, Wait
    CondRefOf, RefOf
    Decrement, Increment
    Load, Unload
    Notify
    Signal, Release, Reset
    SizeOf

Implemented automatic String-to-ObjectReference conversion support for 
packages returned by predefined names (such as _DEP). A common BIOS error 
is to add double quotes around an ObjectReference namepath, which turns 
the reference into an unexpected string object. This support detects the 
problem and corrects it before the package is returned to the caller that 
invoked the method. Lv Zheng.

Implemented extensions to the Concatenate operator. Concatenate now 
accepts any type of object, it is not restricted to simply 
Integer/String/Buffer. For objects other than these 3 basic data types, 
the argument is treated as a string containing the name of the object 
type. This expands the utility of Concatenate and the Printf/Fprintf 
macros. ACPICA BZ 1222.

Cleaned up the output of the ASL Debug object. The timer() value is now 
optional and no longer emitted by default. Also, the basic data types of 
Integer/String/Buffer are simply emitted as their values, without a data 
type string -- since the data type is obvious from the output. ACPICA BZ 
1221.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a much larger code and data size.

  Current Release:
    Non-Debug Version: 102.6K Code, 28.4K Data, 131.0K Total
    Debug Version:     200.3K Code, 81.9K Data, 282.3K Total
  Previous Release:
    Non-Debug Version: 102.0K Code, 28.3K Data, 130.3K Total
    Debug Version:     199.6K Code, 81.8K Data, 281.4K Total


2) iASL Compiler/Disassembler and Tools:

iASL: Fixed some issues with the ASL Include() operator. This operator 
was incorrectly defined in the iASL parser rules, causing a new scope to 
be opened for the code within the include file. This could lead to 
several issues, including allowing ASL code that is technically illegal 
and not supported by AML interpreters. Note, this does not affect the 
related #include preprocessor operator. ACPICA BZ 1212.

iASL/Disassembler: Implemented support for the ASL ElseIf operator. This 
operator is essentially an ASL macro since there is no AML opcode 
associated with it. The code emitted by the iASL compiler for ElseIf is 
an Else opcode followed immediately by an If opcode. The disassembler 
will now emit an ElseIf if it finds an Else immediately followed by an 
If. This simplifies the decoded ASL, especially for deeply nested 
If..Else and large Switch constructs. Thus, the disassembled code more 
closely follows the original source ASL. ACPICA BZ 1211. Example:

    Old disassembly:
        Else
        {
            If (Arg0 == 0x02)
            {
                Local0 = 0x05
            }
        }

    New disassembly:
        ElseIf (Arg0 == 0x02)
        {
            Local0 = 0x05
        }

AcpiExec: Added support for the new module level code behavior and the 
early region installation. This required a small change to the 
initialization, since AcpiExec must install its own operation region 
handlers.

AcpiExec: Added support to make the debug object timer optional. Default 
is timer disabled. This cleans up the debug object output -- the timer 
data is rarely used.

AcpiExec: Multiple ACPI tables are now loaded in the order that they 
appear on the command line. This can be important when there are 
interdependencies/references between the tables.

iASL/Templates. Add support to generate template files with multiple 
SSDTs within a single output file. Also added ommand line support to 
specify the number of SSDTs (in addition to a single DSDT). ACPICA BZ 
1223, 1225.


----------------------------------------
24 November 2015. Summary of changes for version 20151124:

1) ACPICA kernel-resident subsystem:

Fixed a possible regression for a previous update to FADT handling. The 
FADT no longer has a fixed table ID, causing some issues with code that 
was hardwired to a specific ID. Lv Zheng.

Fixed a problem where the method auto-serialization could interfere with 
the current SyncLevel. This change makes the auto-serialization support 
transparent to the SyncLevel support and management.

Removed support for the _SUB predefined name in AcpiGetObjectInfo. This 
interface is intended for early access to the namespace during the 
initial namespace device discovery walk. The _SUB method has been seen to 
access operation regions in some cases, causing errors because the 
operation regions are not fully initialized.

AML Debugger: Fixed some issues with the terminate/quit/exit commands 
that can cause faults. Lv Zheng.

AML Debugger: Add thread ID support so that single-step mode only applies 
to the AML Debugger thread. This prevents runtime errors within some 
kernels. Lv Zheng. 

Eliminated extraneous warnings from AcpiGetSleepTypeData. Since the _Sx 
methods that are invoked by this interface are optional, removed warnings 
emitted for the case where one or more of these methods do not exist. 
ACPICA BZ 1208, original change by Prarit Bhargava.

Made a major pass through the entire ACPICA source code base to 
standardize formatting that has diverged a bit over time. There are no 
functional changes, but this will of course cause quite a few code 
differences from the previous ACPICA release.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a much larger code and data size.

  Current Release:
    Non-Debug Version: 102.0K Code, 28.3K Data, 130.3K Total
    Debug Version:     199.6K Code, 81.8K Data, 281.4K Total
  Previous Release:
    Non-Debug Version: 101.7K Code, 27.9K Data, 129.6K Total
    Debug Version:     199.3K Code, 81.4K Data, 280.7K Total


2) iASL Compiler/Disassembler and Tools:

iASL/acpiexec/acpixtract/disassembler: Added support to allow multiple 
definition blocks within a single ASL file and the resulting AML file. 
Support for this type of file was also added to the various tools that 
use binary AML files: acpiexec, acpixtract, and the AML disassembler. The 
example code below shows two definition blocks within the same file:

    DefinitionBlock ("dsdt.aml", "DSDT", 2, "Intel", "Template", 
0x12345678)
    {
    }
    DefinitionBlock ("", "SSDT", 2, "Intel", "Template", 0xABCDEF01)
    {
    }

iASL: Enhanced typechecking for the Name() operator. All expressions for 
the value of the named object must be reduced/folded to a single constant 
at compile time, as per the ACPI specification (the AML definition of 
Name()).

iASL: Fixed some code indentation issues for the -ic and -ia options (C 
and assembly headers). Now all emitted code correctly begins in column 1.

iASL: Added an error message for an attempt to open a Scope() on an 
object defined in an SSDT. The DSDT is always loaded into the namespace 
first, so any attempt to open a Scope on an SSDT object will fail at 
runtime.


----------------------------------------
30 September 2015. Summary of changes for version 20150930:

1) ACPICA kernel-resident subsystem:

Debugger: Implemented several changes and bug fixes to assist support for 
the in-kernel version of the AML debugger. Lv Zheng.
- Fix the "predefined" command for in-kernel debugger.
- Do not enter debug command loop for the help and version commands.
- Disallow "execute" command during execution/single-step of a method.

Interpreter: Updated runtime typechecking for all operators that have 
target operands. The operand is resolved and validated that it is legal. 
For example, the target cannot be a non-data object such as a Device, 
Mutex, ThermalZone, etc., as per the ACPI specification.

Debugger: Fixed the double-mutex user I/O handshake to work when local 
deadlock detection is enabled.

Debugger: limited display of method locals and arguments (LocalX and 
ArgX) to only those that have actually been initialized. This prevents 
lines of extraneous output.

Updated the definition of the NFIT table to correct the bit polarity of 
one flag: ACPI_NFIT_MEM_ARMED --> ACPI_NFIT_MEM_NOT_ARMED

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a much larger code and data size.

  Current Release:
    Non-Debug Version: 101.7K Code, 27.9K Data, 129.6K Total
    Debug Version:     199.3K Code, 81.4K Data, 280.7K Total
  Previous Release:
    Non-Debug Version: 101.3K Code, 27.7K Data, 129.0K Total
    Debug Version:     198.6K Code, 80.9K Data, 279.5K Total


2) iASL Compiler/Disassembler and Tools:

iASL: Improved the compile-time typechecking for operands of many of the 
ASL operators:

-- Added an option to disable compiler operand/operator typechecking (-
ot).

-- For the following operators, the TermArg operands are now validated 
when possible to be Integer data objects: BankField, OperationRegion, 
DataTableRegion, Buffer, and Package.

-- Store (Source, Target): Both the source and target operands are 
resolved and checked that the operands are both legal. For example, 
neither operand can be a non-data object such as a Device, Mutex, 
ThermalZone, etc. Note, as per the ACPI specification, the CopyObject 
operator can be used to store an object to any type of target object.

-- Store (Source, Target): If the source is a Package object, the target 
must be a Package object, LocalX, ArgX, or Debug. Likewise, if the target 
is a Package, the source must also be a Package.

-- Store (Source, Target): A warning is issued if the source and target 
resolve to the identical named object.

-- Store (Source, <method invocation>): An error is generated for the 
target method invocation, as this construct is not supported by the AML 
interpreter.

-- For all ASL math and logic operators, the target operand must be a 
data object (Integer, String, Buffer, LocalX, ArgX, or Debug). This 
includes the function return value also.

-- External declarations are also included in the typechecking where 
possible. External objects defined using the UnknownObj keyword cannot be 
typechecked, however.

iASL and Disassembler: Added symbolic (ASL+) support for the ASL Index 
operator:
- Legacy code: Index(PKG1, 3)
- New ASL+ code: PKG1[3]
This completes the ACPI 6.0 ASL+ support as it was the only operator not 
supported.

iASL: Fixed the file suffix for the preprocessor output file (.i). Two 
spaces were inadvertently appended to the filename, causing file access 
and deletion problems on some systems.

ASL Test Suite (ASLTS): Updated the master makefile to generate all 
possible compiler output files when building the test suite -- thus 
exercising these features of the compiler. These files are automatically 
deleted when the test suite exits.


----------------------------------------
18 August 2015. Summary of changes for version 20150818:

1) ACPICA kernel-resident subsystem:

Fix a regression for AcpiGetTableByIndex interface causing it to fail. Lv 
Zheng. ACPICA BZ 1186.

Completed development to ensure that the ACPICA Disassembler and Debugger 
are fully standalone components of ACPICA. Removed cross-component 
dependences. Lv Zheng.

The max-number-of-AML-loops is now runtime configurable (previously was 
compile-time only). This is essentially a loop timeout to force-abort 
infinite AML loops. ACPCIA BZ 1192.

Debugger: Cleanup output to dump ACPI names and namepaths without any 
trailing underscores. Lv Zheng. ACPICA BZ 1135.

Removed unnecessary conditional compilations across the Debugger and 
Disassembler components where entire modules could be left uncompiled.

The aapits test is deprecated and has been removed from the ACPICA git 
tree. The test has never been completed and has not been maintained, thus 
becoming rather useless. ACPICA BZ 1015, 794.

A batch of small changes to close bugzilla and other reports:
- Remove duplicate code for _PLD processing. ACPICA BZ 1176.
- Correctly cleanup after a ACPI table load failure. ACPICA BZ 1185.
- iASL: Support POSIX yacc again in makefile. Jung-uk Kim.
- ACPI table support: general cleanup and simplification. Lv Zheng, Bob 
Moore.
- ACPI table support: fix for a buffer read overrun in AcpiTbFindTable. 
ACPICA BZ 1184.
- Enhance parameter validation for DataTableRegion and LoadTable ASL/AML 
operators.
- Debugger: Split debugger initialization/termination interfaces. Lv 
Zheng.
- AcpiExec: Emit OemTableId for SSDTs during the load phase for table 
identification.
- AcpiExec: Add debug message during _REG method phase during table 
load/init.
- AcpiNames: Fix a regression where some output was missing and no longer 
emitted.
- Debugger: General cleanup and simplification. Lv Zheng.
- Disassembler: Cleanup use of several global option variables. Lv Zheng.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a much larger code and data size.

  Current Release:
    Non-Debug Version: 101.3K Code, 27.7K Data, 129.0K Total
    Debug Version:     198.6K Code, 80.9K Data, 279.5K Total
  Previous Release:
    Non-Debug Version: 100.9K Code, 24.5K Data, 125.4K Total
    Debug Version:     197.8K Code, 81.5K Data, 279.3K Total


2) iASL Compiler/Disassembler and Tools:

AcpiExec: Fixed a problem where any more than 32 ACPI tables in the XSDT 
were not handled properly and caused load errors. Now, properly invoke 
and use the ACPICA auto-reallocate mechanism for ACPI table data 
structures. ACPICA BZ 1188

AcpiNames: Add command-line wildcard support for ACPI table files. ACPICA 
BZ 1190.

AcpiExec and AcpiNames: Add -l option to load ACPI tables only. For 
AcpiExec, this means that no control methods (like _REG/_INI/_STA) are 
executed during initialization. ACPICA BZ 1187, 1189.

iASL/Disassembler: Implemented a prototype "listing" mode that emits AML 
that corresponds to each disassembled ASL statement, to simplify 
debugging. ACPICA BZ 1191.

Debugger: Add option to the "objects" command to display a summary of the 
current namespace objects (Object type and count). This is displayed if 
the command is entered with no arguments.

AcpiNames: Add -x option to specify debug level, similar to AcpiExec.


----------------------------------------
17 July 2015. Summary of changes for version 20150717:

1) ACPICA kernel-resident subsystem:

Improved the partitioning between the Debugger and Disassembler 
components. This allows the Debugger to be used standalone within kernel 
code without the Disassembler (which is used for single stepping also). 
This renames and moves one file, dmobject.c to dbobject.c. Lv Zheng.

Debugger: Implemented a new command to trace the execution of control 
methods (Trace). This is especially useful for the in-kernel version of 
the debugger when file I/O may not be available for method trace output. 
See the ACPICA reference for more information. Lv Zheng.

Moved all C library prototypes (used for the local versions of these 
functions when requested) to a new header, acclib.h
Cleaned up the use of non-ANSI C library functions. These functions are 
implemented locally in ACPICA. Moved all such functions to a common 
source file, utnonansi.c

Debugger: Fixed a problem with the "!!" command (get last command 
executed) where the debugger could enter an infinite loop and eventually 
crash.

Removed the use of local macros that were used for some of the standard C 
library functions to automatically cast input parameters. This mostly 
affected the is* functions where the input parameter is defined to be an 
int. This required a few modifications to the main ACPICA source code to 
provide casting for these functions and eliminate possible compiler 
warnings for these parameters.

Across the source code, added additional status/error checking to resolve 
issues discovered by static source code analysis tools such as Coverity.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a much larger code and data size.

  Current Release:
    Non-Debug Version: 100.9K Code, 24.5K Data, 125.4K Total
    Debug Version:     197.8K Code, 81.5K Data, 279.3K Total
  Previous Release:
    Non-Debug Version: 100.6K Code, 27.6K Data, 128.2K Total
    Debug Version:     196.2K Code, 81.0K Data, 277.2K Total


2) iASL Compiler/Disassembler and Tools:

iASL: Fixed a regression where the device map file feature no longer 
worked properly when used in conjunction with the disassembler. It only 
worked properly with the compiler itself.

iASL: Implemented a new warning for method LocalX variables that are set 
but never used (similar to a C compiler such as gcc). This also applies 
to ArgX variables that are not defined by the parent method, and are 
instead (legally) used as local variables.

iASL/Preprocessor: Finished the pass-through of line numbers from the 
preprocessor to the compiler. This ensures that compiler errors/warnings 
have the correct original line numbers and filenames, regardless of any 
#include files.

iASL/Preprocessor: Fixed a couple of issues with comment handling and the 
pass-through of comments to the preprocessor output file (which becomes 
the compiler input file). Also fixed a problem with // comments that 
appear after a math expression.

iASL: Added support for the TCPA server table to the table compiler and 
template generator. (The client table was already previously supported)

iASL/Preprocessor: Added a permanent #define of the symbol "__IASL__" to 
identify the iASL compiler.

Cleaned up the use of the macros NEGATIVE and POSITIVE which were defined 
multiple times. The new names are ACPI_SIGN_NEGATIVE and 
ACPI_SIGN_POSITIVE.

AcpiHelp: Update to expand help messages for the iASL preprocessor 
directives.


----------------------------------------
19 June 2015. Summary of changes for version 20150619:

Two regressions in version 20150616 have been addressed:

Fixes some problems/issues with the C library macro removal (ACPI_STRLEN, 
etc.) This update changes ACPICA to only use the standard headers for 
functions, or the prototypes for the local versions of the C library 
functions. Across the source code, this required some additional casts 
for some Clib invocations for portability. Moved all local prototypes to 
a new file, acclib.h

Fixes several problems with recent changes to the handling of the FACS 
table that could cause some systems not to boot.


----------------------------------------
16 June 2015. Summary of changes for version 20150616:


1) ACPICA kernel-resident subsystem:

Across the entire ACPICA source code base, the various macros for the C 
library functions (such as ACPI_STRLEN, etc.) have been removed and 
replaced by the standard C library names (strlen, etc.) The original 
purpose for these macros is no longer applicable. This simplification 
reduces the number of macros used in the ACPICA source code 
significantly, improving readability and maintainability.

Implemented support for a new ACPI table, the OSDT. This table, the 
"override" SDT, can be loaded directly by the host OS at boot time. It 
enables the replacement of existing namespace objects that were installed 
via the DSDT and/or SSDTs. The primary purpose for this is to replace 
buggy or incorrect ASL/AML code obtained via the BIOS. The OSDT is slated 
for inclusion in a future version of the ACPI Specification. Lv Zheng/Bob 
Moore.

Added support for systems with (improperly) two FACS tables -- a "32-bit" 
table (via FADT 32-bit legacy field) and a "64-bit" table (via the 64-bit 
X field). This change will support both automatically. There continues to 
be systems found with this issue. This support requires a change to the 
AcpiSetFirmwareWakingVector interface. Also, a public global variable has 
been added to allow the host to select which FACS is desired 
(AcpiGbl_Use32BitFacsAddresses). See the ACPICA reference for more 
details Lv Zheng.

Added a new feature to allow for systems that do not contain an FACS. 
Although this is already supported on hardware-reduced platforms, the 
feature has been extended for all platforms. The reasoning is that we do 
not want to abort the entire ACPICA initialization just because the 
system is seriously buggy and has no FACS.

Fixed a problem where the GUID strings for NFIT tables (in acuuid.h) were 
not correctly transcribed from the ACPI specification in ACPICA version 
20150515.

Implemented support for the _CLS object in the AcpiGetObjectInfo external 
interface.

Updated the definitions of the TCPA and TPM2 ACPI tables to the more 
recent TCG ACPI Specification, December 14, 2014. Table disassembler and 
compiler also updated. Note: The TCPA "server" table is not supported by 
the disassembler/table-compiler at this time.

ACPI 6.0: Added definitions for the new GIC version field in the MADT.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a much larger code and data size.

  Current Release:
    Non-Debug Version: 100.6K Code, 27.6K Data, 128.2K Total
    Debug Version:     196.2K Code, 81.0K Data, 277.2K Total
  Previous Release:
    Non-Debug Version:  99.9K Code, 27.5K Data, 127.4K Total
    Debug Version:     195.2K Code, 80.8K Data, 276.0K Total


2) iASL Compiler/Disassembler and Tools:

Disassembler: Fixed a problem with the new symbolic operator disassembler 
where incorrect ASL code could be emitted in some cases for the "non-
commutative" operators -- Subtract, Divide, Modulo, ShiftLeft, and 
ShiftRight. The actual problem cases seem to be rather unusual in common 
ASL code, however. David Box.

Modified the linux version of acpidump to obtain ACPI tables from not 
just /dev/mem (which may not exist) and /sys/firmware/acpi/tables. Lv 
Zheng.

iASL: Fixed a problem where the user preprocessor output file (.i) 
contained extra data that was not expected. The compiler was using this 
file as a temporary file and passed through #line directives in order to 
keep compiler error messages in sync with the input file and line number 
across multiple include files. The (.i) is no longer a temporary file as 
the compiler uses a new, different file for the original purpose.

iASL: Fixed a problem where comments within the original ASL source code 
file were not passed through to the preprocessor output file, nor any 
listing files.

iASL: Fixed some issues for the handling of the "#include" preprocessor 
directive and the similar (but not the same) "Include" ASL operator.

iASL: Add support for the new OSDT in both the disassembler and compiler.

iASL: Fixed a problem with the constant folding support where a Buffer 
object could be incorrectly generated (incorrectly formed) during a 
conversion to a Store() operator.

AcpiHelp: Updated for new NFIT GUIDs, "External" AML opcode, and new 
description text for the _REV predefined name. _REV now permanently 
returns 2, as per the ACPI 6.0 specification.

Debugger: Enhanced the output of the Debug ASL object for references 
produced by the Index operator. For Buffers and strings, only output the 
actual byte pointed to by the index. For packages, only print the single 
package element decoded by the index. Previously, the entire 
buffer/string/package was emitted.

iASL/Table-compiler: Fixed a regression where the "generic" data types 
were no longer recognized, causing errors.


----------------------------------------
15 May 2015. Summary of changes for version 20150515:

This release implements most of ACPI 6.0 as described below.

1) ACPICA kernel-resident subsystem:

Implemented runtime argument checking and return value checking for all 
new ACPI 6.0 predefined names. This includes: _BTH, _CR3, _DSD, _LPI, 
_MTL, _PRR, _RDI, _RST, _TFP, _TSN.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a much larger code and data size.

  Current Release:
    Non-Debug Version:  99.9K Code, 27.5K Data, 127.4K Total
    Debug Version:     195.2K Code, 80.8K Data, 276.0K Total
  Previous Release:
    Non-Debug Version:  99.1K Code, 27.3K Data, 126.4K Total
    Debug Version:     192.8K Code, 79.9K Data, 272.7K Total


2) iASL Compiler/Disassembler and Tools:

iASL compiler: Added compile-time support for all new ACPI 6.0 predefined 
names (argument count validation and return value typechecking.)

iASL disassembler and table compiler: implemented support for all new 
ACPI 6.0 tables. This includes: DRTM, IORT, LPIT, NFIT, STAO, WPBT, XENV. 

iASL disassembler and table compiler: Added ACPI 6.0 changes to existing 
tables: FADT, MADT.

iASL preprocessor: Added a new directive to enable inclusion of binary 
blobs into ASL code. The new directive is #includebuffer. It takes a 
binary file as input and emits a named ascii buffer object into the ASL 
code.

AcpiHelp: Added support for all new ACPI 6.0 predefined names.

AcpiHelp: Added a new option, -d, to display all iASL preprocessor 
directives.

AcpiHelp: Added a new option, -t, to display all known/supported ACPI 
tables.


----------------------------------------
10 April 2015. Summary of changes for version 20150410:

Reverted a change introduced in version 20150408 that caused
a regression in the disassembler where incorrect operator
symbols could be emitted.


----------------------------------------
08 April 2015. Summary of changes for version 20150408:


1) ACPICA kernel-resident subsystem:

Permanently set the return value for the _REV predefined name. It now 
returns 2 (was 5). This matches other ACPI implementations. _REV will be 
deprecated in the future, and is now defined to be 1 for ACPI 1.0, and 2 
for ACPI 2.0 and later. It should never be used to differentiate or 
identify operating systems.

Added the "Windows 2015" string to the _OSI support. ACPICA will now 
return TRUE to a query with this string.

Fixed several issues with the local version of the printf function.

Added the C99 compiler option (-std=c99) to the Unix makefiles.

  Current Release:
    Non-Debug Version:  99.9K Code, 27.4K Data, 127.3K Total
    Debug Version:     195.2K Code, 80.7K Data, 275.9K Total
  Previous Release:
    Non-Debug Version:  98.8K Code, 27.3K Data, 126.1K Total
    Debug Version:     192.1K Code, 79.8K Data, 271.9K Total


2) iASL Compiler/Disassembler and Tools:

iASL: Implemented an enhancement to the constant folding feature to 
transform the parse tree to a simple Store operation whenever possible:
    Add (2, 3, X) ==> is converted to: Store (5, X)
    X = 2 + 3     ==> is converted to: Store (5, X)

Updated support for the SLIC table (Software Licensing Description Table) 
in both the Data Table compiler and the disassembler. The SLIC table 
support now conforms to "Microsoft Software Licensing Tables (SLIC and 
MSDM). November 29, 2011. Copyright 2011 Microsoft". Note: Any SLIC data 
following the ACPI header is now defined to be "Proprietary Data", and as 
such, can only be entered or displayed as a hex data block.

Implemented full support for the MSDM table as described in the document 
above. Note: The format of MSDM is similar to SLIC. Any MSDM data 
following the ACPI header is defined to be "Proprietary Data", and can 
only be entered or displayed as a hex data block.

Implemented the -Pn option for the iASL Table Compiler (was only 
implemented for the ASL compiler). This option disables the iASL 
preprocessor.

Disassembler: For disassembly of Data Tables, added a comment field 
around the Ascii equivalent data that is emitted as part of the "Raw 
Table Data" block. This prevents the iASL Preprocessor from possible 
confusion if/when the table is compiled.

Disassembler: Added an option (-df) to force the disassembler to assume 
that the table being disassembled contains valid AML. This feature is 
useful for disassembling AML files that contain ACPI signatures other 
than DSDT or SSDT (such as OEMx or other signatures).

Changes for the EFI version of the tools:
1) Fixed a build error/issue
2) Fixed a cast warning

iASL: Fixed a path issue with the __FILE__ operator by making the 
directory prefix optional within the internal SplitInputFilename 
function.

Debugger: Removed some unused global variables.

Tests: Updated the makefile for proper generation of the AAPITS suite.


----------------------------------------
04 February 2015. Summary of changes for version 20150204:

ACPICA kernel-resident subsystem:

Updated all ACPICA copyrights and signons to 2014. Added the 2014 
copyright to all module headers and signons, including the standard Linux 
header. This affects virtually every file in the ACPICA core subsystem, 
iASL compiler, all ACPICA utilities, and the test suites.

Events: Introduce ACPI_GPE_DISPATCH_RAW_HANDLER to fix GPE storm issues.
A raw gpe handling mechanism was created to allow better handling of GPE
storms that aren't easily managed by the normal handler. The raw handler
allows disabling/renabling of the the GPE so that interrupt storms can be
avoided in cases where events cannot be timely serviced. In this 
scenario, handlers should use the AcpiSetGpe() API to disable/enable the 
GPE. This API will leave the reference counts undisturbed, thereby 
preventing unintentional clearing of the GPE when the intent in only to 
temporarily disable it. Raw handlers allow enabling and disabling of a 
GPE by removing GPE register locking. As such, raw handlers much provide 
their own locks while using GPE API's to protect access to GPE data 
structures.
Lv Zheng

Events: Always modify GPE registers under the GPE lock.
Applies GPE lock around AcpiFinishGpe() to protect access to GPE register
values. Reported as bug by joe.liu@apple.com.

Unix makefiles: Separate option to disable optimizations and 
_FORTIFY_SOURCE. This change removes the _FORTIFY_SOURCE flag from the 
NOOPT disable option and creates a separate flag (NOFORTIFY) for this 
purpose. Some toolchains may define _FORTIFY_SOURCE which leads redefined 
errors when building ACPICA. This allows disabling the option without 
also having to disable optimazations.
David Box

--------------------------------------
07 November 2014. Summary of changes for version 20141107:

This release is available at https://acpica.org/downloads

This release introduces and implements language extensions to ASL that 
provide support for symbolic ("C-style") operators and expressions. These 
language extensions are known collectively as ASL+.


1) iASL Compiler/Disassembler and Tools:

Disassembler: Fixed a problem with disassembly of the UartSerialBus 
macro. Changed "StopBitsNone" to the correct "StopBitsZero". David E. 
Box.

Disassembler: Fixed the Unicode macro support to add escape sequences. 
All non-printable ASCII values are emitted as escape sequences, as well 
as the standard escapes for quote and backslash. Ensures that the 
disassembled macro can be correctly recompiled.

iASL: Added Printf/Fprintf macros for formatted output. These macros are 
translated to existing AML Concatenate and Store operations. Printf 
writes to the ASL Debug object. Fprintf allows the specification of an 
ASL name as the target. Only a single format specifier is required, %o, 
since the AML interpreter dynamically converts objects to the required 
type. David E. Box.

    (old)    Store (Concatenate (Concatenate (Concatenate (Concatenate
                 (Concatenate (Concatenate (Concatenate ("", Arg0),
                 ": Unexpected value for "), Arg1), ", "), Arg2),
                 " at line "), Arg3), Debug)

    (new)    Printf ("%o: Unexpected value for %o, %o at line %o",
                 Arg0, Arg1, Arg2, Arg3)

    (old)    Store (Concatenate (Concatenate (Concatenate (Concatenate
                 ("", Arg1), ": "), Arg0), " Successful"), STR1)

    (new)    Fprintf (STR1, "%o: %o Successful", Arg1, Arg0)

iASL: Added debug options (-bp, -bt) to dynamically prune levels of the 
ASL parse tree before the AML code is generated. This allows blocks of 
ASL code to be removed in order to help locate and identify problem 
devices and/or code. David E. Box.

AcpiExec: Added support (-fi) for an optional namespace object 
initialization file. This file specifies initial values for namespace 
objects as necessary for debugging and testing different ASL code paths 
that may be taken as a result of BIOS options.


2) Overview of symbolic operator support for ASL (ASL+)
-------------------------------------------------------

As an extension to the ASL language, iASL implements support for symbolic 
(C-style) operators for math and logical expressions. This can greatly 
simplify ASL code as well as improve both readability and 
maintainability. These language extensions can exist concurrently with 
all legacy ASL code and expressions.

The symbolic extensions are 100% compatible with existing AML 
interpreters, since no new AML opcodes are created. To implement the 
extensions, the iASL compiler transforms the symbolic expressions into 
the legacy ASL/AML equivalents at compile time.

Full symbolic expressions are supported, along with the standard C 
precedence and associativity rules.

Full disassembler support for the symbolic expressions is provided, and 
creates an automatic migration path for existing ASL code to ASL+ code 
via the disassembly process. By default, the disassembler now emits ASL+ 
code with symbolic expressions. An option (-dl) is provided to force the 
disassembler to emit legacy ASL code if desired.

Below is the complete list of the currently supported symbolic operators 
with examples. See the iASL User Guide for additional information.


ASL+ Syntax      Legacy ASL Equivalent
-----------      ---------------------

    // Math operators

Z = X + Y        Add (X, Y, Z)
Z = X - Y        Subtract (X, Y, Z)
Z = X * Y        Multiply (X, Y, Z)
Z = X / Y        Divide (X, Y, , Z)
Z = X % Y        Mod (X, Y, Z)
Z = X << Y       ShiftLeft (X, Y, Z)
Z = X >> Y       ShiftRight (X, Y, Z)
Z = X & Y        And (X, Y, Z)
Z = X | Y        Or (X, Y, Z)
Z = X ^ Y        Xor (X, Y, Z)
Z = ~X           Not (X, Z)
X++              Increment (X)
X--              Decrement (X)

    // Logical operators

(X == Y)         LEqual (X, Y)
(X != Y)         LNotEqual (X, Y)
(X < Y)          LLess (X, Y)
(X > Y)          LGreater (X, Y)
(X <= Y)         LLessEqual (X, Y)
(X >= Y)         LGreaterEqual (X, Y)
(X && Y)         LAnd (X, Y)
(X || Y)         LOr (X, Y)
(!X)             LNot (X)

    // Assignment and compound assignment operations

X = Y           Store (Y, X)
X += Y          Add (X, Y, X)
X -= Y          Subtract (X, Y, X)
X *= Y          Multiply (X, Y, X)
X /= Y          Divide (X, Y, , X)
X %= Y          Mod (X, Y, X)
X <<= Y         ShiftLeft (X, Y, X)
X >>= Y         ShiftRight (X, Y, X)
X &= Y          And (X, Y, X)
X |= Y          Or (X, Y, X)
X ^= Y          Xor (X, Y, X)


3) ASL+ Examples:
-----------------

Legacy ASL:
        If (LOr (LOr (LEqual (And (R510, 0x03FB), 0x02E0), LEqual (
            And (R520, 0x03FB), 0x02E0)), LOr (LEqual (And (R530, 
0x03FB), 
            0x02E0), LEqual (And (R540, 0x03FB), 0x02E0))))
        {
            And (MEMB, 0xFFFFFFF0, SRMB)
            Store (MEMB, Local2)
            Store (PDBM, Local1)
            And (PDBM, 0xFFFFFFFFFFFFFFF9, PDBM)
            Store (SRMB, MEMB)
            Or (PDBM, 0x02, PDBM)
        }

ASL+ version:
        If (((R510 & 0x03FB) == 0x02E0) ||
            ((R520 & 0x03FB) == 0x02E0) ||
            ((R530 & 0x03FB) == 0x02E0) || 
            ((R540 & 0x03FB) == 0x02E0))
        {
            SRMB = (MEMB & 0xFFFFFFF0)
            Local2 = MEMB
            Local1 = PDBM
            PDBM &= 0xFFFFFFFFFFFFFFF9
            MEMB = SRMB
            PDBM |= 0x02
        }

Legacy ASL:

        Local3 = (((Local1 + TEST) + 0x20) * ToBCD (Local1))


----------------------------------------
26 September 2014. Summary of changes for version 20140926:

1) ACPICA kernel-resident subsystem:

Updated the GPIO operation region handler interface (GeneralPurposeIo). 
In order to support GPIO Connection objects with multiple pins, along 
with the related Field objects, the following changes to the interface 
have been made: The Address is now defined to be the offset in bits of 
the field unit from the previous invocation of a Connection. It can be 
viewed as a "Pin Number Index" into the connection resource descriptor. 
The BitWidth is the exact bit width of the field. It is usually one bit, 
but not always. See the ACPICA reference guide (section 8.8.6.2.1) for 
additional information and examples.

GPE support: During ACPICA/GPE initialization, ensure that all GPEs with 
corresponding _Lxx/_Exx methods are disabled (they may have been enabled 
by the firmware), so that they cannot fire until they are enabled via 
AcpiUpdateAllGpes. Rafael J. Wysocki.

Added a new return flag for the Event/GPE status interfaces -- 
AcpiGetEventStatus and AcpiGetGpeStatus. The new 
ACPI_EVENT_FLAGS_HAS_HANDLER flag is used to indicate that the event or 
GPE currently has a handler associated with it, and can thus actually 
affect the system. Lv Zheng.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a much larger code and data size.

  Current Release:
    Non-Debug Version:  99.1K Code, 27.3K Data, 126.4K Total
    Debug Version:     192.8K Code, 79.9K Data, 272.7K Total
  Previous Release:
    Non-Debug Version:  98.8K Code, 27.3K Data, 126.1K Total
    Debug Version:     192.1K Code, 79.8K Data, 271.9K Total

2) iASL Compiler/Disassembler and Tools:

iASL: Fixed a memory allocation/free regression introduced in 20140828 
that could cause the compiler to crash. This was introduced inadvertently 
during the effort to eliminate compiler memory leaks. ACPICA BZ 1111, 
1113.

iASL: Removed two error messages that have been found to create false 
positives, until they can be fixed and fully validated (ACPICA BZ 1112):
1) Illegal forward reference within a method
2) Illegal reference across two methods

iASL: Implemented a new option (-lm) to create a hardware mapping file 
that summarizes all GPIO, I2C, SPI, and UART connections. This option 
works for both the compiler and disassembler. See the iASL compiler user 
guide for additional information and examples (section 6.4.6).

AcpiDump: Added support for the version 1 (ACPI 1.0) RSDP in addition to 
version 2. This corrects the AE_BAD_HEADER exception seen on systems with 
a version 1 RSDP. Lv Zheng ACPICA BZ 1097.

AcpiExec: For Unix versions, don't attempt to put STDIN into raw mode 
unless STDIN is actually a terminal. Assists with batch-mode processing. 
ACPICA BZ 1114.

Disassembler/AcpiHelp: Added another large group of recognized _HID 
values.


----------------------------------------
28 August 2014. Summary of changes for version 20140828:

1) ACPICA kernel-resident subsystem:

Fixed a problem related to the internal use of the Timer() operator where 
a 64-bit divide could cause an attempted link to a double-precision math 
library. This divide is not actually necessary, so the code was 
restructured to eliminate it. Lv Zheng.

ACPI 5.1: Added support for the runtime validation of the _DSD package 
(similar to the iASL support).

ACPI 5.1/Headers: Added support for the GICC affinity subtable to the 
SRAT table. Hanjun Guo <hanjun.guo@linaro.org>.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a much larger code and data size.

  Current Release:
    Non-Debug Version:  98.8K Code, 27.3K Data, 126.1K Total
    Debug Version:     192.1K Code, 79.8K Data, 271.9K Total
  Previous Release:
    Non-Debug Version:  98.7K Code, 27.3K Data, 126.0K Total1
    Debug Version:     192.0K Code, 79.7K Data, 271.7K Total

2) iASL Compiler/Disassembler and Tools:

AcpiExec: Fixed a problem on unix systems where the original terminal 
state was not always properly restored upon exit. Seen when using the -v 
option. ACPICA BZ 1104.

iASL: Fixed a problem with the validation of the ranges/length within the 
Memory24 resource descriptor. There was a boundary condition when the 
range was equal to the (length -1) caused by the fact that these values 
are defined in 256-byte blocks, not bytes. ACPICA BZ 1098

Disassembler: Fixed a problem with the GpioInt descriptor interrupt 
polarity 
flags. The flags are actually 2 bits, not 1, and the "ActiveBoth" keyword 
is 
now supported properly.

ACPI 5.1: Added the GICC affinity subtable to the SRAT table. Supported 
in the disassembler, data table compiler, and table template generator.

iASL: Added a requirement for Device() objects that one of either a _HID 
or _ADR must exist within the scope of a Device, as per the ACPI 
specification. Remove a similar requirement that was incorrectly in place 
for the _DSD object.

iASL: Added error detection for illegal named references within control 
methods that would cause runtime failures. Now trapped as errors are: 1) 
References to objects within a non-parent control method. 2) Forward 
references (within a method) -- for control methods, AML interpreters use 
a one-pass parse of control methods. ACPICA BZ 1008.

iASL: Added error checking for dependencies related to the _PSx power 
methods. ACPICA BZ 1029.
1) For _PS0, one of these must exist within the same scope: _PS1, _PS2, 
_PS3.
2) For _PS1, _PS2, and PS3: A _PS0 object must exist within the same 
scope.

iASL and table compiler: Cleanup miscellaneous memory leaks by fully 
deploying the existing object and string caches and adding new caches for 
the table compiler.

iASL: Split the huge parser source file into multiple subfiles to improve 
manageability. Generation now requires the M4 macro preprocessor, which 
is part of the Bison distribution on both unix and windows platforms.

AcpiSrc: Fixed and removed all extraneous warnings generated during 
entire ACPICA source code scan and/or conversion.


----------------------------------------

24 July 2014. Summary of changes for version 20140724: 

The ACPI 5.1 specification has been released and is available at: 
http://uefi.org/specs/access


0) ACPI 5.1 support in ACPICA:

ACPI 5.1 is fully supported in ACPICA as of this release.

New predefined names. Support includes iASL and runtime ACPICA 
validation.
    _CCA (Cache Coherency Attribute).
    _DSD (Device-Specific Data). David Box.

Modifications to existing ACPI tables. Support includes headers, iASL 
Data Table compiler, disassembler, and the template generator.
    FADT - New fields and flags. Graeme Gregory.
    GTDT - One new subtable and new fields. Tomasz Nowicki.
    MADT - Two new subtables. Tomasz Nowicki.
    PCCT - One new subtable.

Miscellaneous.
    New notification type for System Resource Affinity change events.


1) ACPICA kernel-resident subsystem:

Fixed a regression introduced in 20140627 where a fault can happen during 
the deletion of Alias AML namespace objects. The problem affected both 
the core ACPICA and the ACPICA tools including iASL and AcpiExec.

Implemented a new GPE public interface, AcpiMarkGpeForWake. Provides a 
simple mechanism to enable wake GPEs that have no associated handler or 
control method. Rafael Wysocki.

Updated the AcpiEnableGpe interface to disallow the enable if there is no 
handler or control method associated with the particular GPE. This will 
help avoid meaningless GPEs and even GPE floods. Rafael Wysocki.

Updated GPE handling and dispatch by disabling the GPE before clearing 
the status bit for edge-triggered GPEs. Lv Zheng.

Added Timer() support to the AML Debug object. The current timer value is 
now displayed with each invocation of (Store to) the debug object to 
enable simple generation of execution times for AML code (method 
execution for example.) ACPICA BZ 1093.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a much larger code and data size.

  Current Release:
    Non-Debug Version:  98.7K Code, 27.3K Data, 126.0K Total
    Debug Version:     192.0K Code, 79.7K Data, 271.7K Total
  Previous Release:
    Non-Debug Version:  98.7K Code, 27.2K Data, 125.9K Total
    Debug Version:     191.7K Code, 79.6K Data, 271.3K Total


2) iASL Compiler/Disassembler and Tools:

Fixed an issue with the recently added local printf implementation, 
concerning width/precision specifiers that could cause incorrect output. 
Lv Zheng. ACPICA BZ 1094.

Disassembler: Added support to detect buffers that contain UUIDs and 
disassemble them to an invocation of the ToUUID operator. Also emit 
commented descriptions of known ACPI-related UUIDs.

AcpiHelp: Added support to display known ACPI-related UUIDs. New option, 
-u. Adds three new files. 

iASL: Update table compiler and disassembler for DMAR table changes that 
were introduced in September 2013. With assistance by David Woodhouse.

----------------------------------------
27 June 2014. Summary of changes for version 20140627:

1) ACPICA kernel-resident subsystem:

Formatted Output: Implemented local versions of standard formatted output 
utilities such as printf, etc. Over time, it has been discovered that 
there are in fact many portability issues with printf, and the addition 
of this feature will fix/prevent these issues once and for all. Some 
known issues are summarized below:

1) Output of 64-bit values is not portable. For example, UINT64 is %ull 
for the Linux kernel and is %uI64 for some MSVC versions.
2) Invoking printf consistently in a manner that is portable across both 
32-bit and 64-bit platforms is difficult at best in many situations.
3) The output format for pointers varies from system to system (leading 
zeros especially), and leads to inconsistent output from ACPICA across 
platforms.
4) Certain platform-specific printf formats may conflict with ACPICA use.
5) If there is no local C library available, ACPICA now has local support 
for printf.

-- To address these printf issues in a complete manner, ACPICA now 
directly implements a small subset of printf format specifiers, only 
those that it requires. Adds a new file, utilities/utprint.c. Lv Zheng.

Implemented support for ACPICA generation within the EFI environment. 
Initially, the AcpiDump utility is supported in the UEFI shell 
environment. Lv Zheng.

Added a new external interface, AcpiLogError, to improve ACPICA 
portability. This allows the host to redirect error messages from the 
ACPICA utilities. Lv Zheng.

Added and deployed new OSL file I/O interfaces to improve ACPICA 
portability:
  AcpiOsOpenFile
  AcpiOsCloseFile
  AcpiOsReadFile
  AcpiOsWriteFile
  AcpiOsGetFileOffset
  AcpiOsSetFileOffset
There are C library implementations of these functions in the new file 
service_layers/oslibcfs.c -- however, the functions can be implemented by 
the local host in any way necessary. Lv Zheng.

Implemented a mechanism to disable/enable ACPI table checksum validation 
at runtime. This can be useful when loading tables very early during OS 
initialization when it may not be possible to map the entire table in 
order to compute the checksum. Lv Zheng.

Fixed a buffer allocation issue for the Generic Serial Bus support. 
Originally, a fixed buffer length was used. This change allows for 
variable-length buffers based upon the protocol indicated by the field 
access attributes. Reported by Lan Tianyu. Lv Zheng.

Fixed a problem where an object detached from a namespace node was not 
properly terminated/cleared and could cause a circular list problem if 
reattached. ACPICA BZ 1063. David Box.

Fixed a possible recursive lock acquisition in hwregs.c. Rakib Mullick.

Fixed a possible memory leak in an error return path within the function 
AcpiUtCopyIobjectToIobject. ACPICA BZ 1087. Colin Ian King.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a much larger code and data size.

  Current Release:
    Non-Debug Version:  98.7K Code, 27.2K Data, 125.9K Total
    Debug Version:     191.7K Code, 79.6K Data, 271.3K Total
  Previous Release:
    Non-Debug Version:  96.8K Code, 27.2K Data, 124.0K Total
    Debug Version:     189.5K Code, 79.7K Data, 269.2K Total


2) iASL Compiler/Disassembler and Tools:

Disassembler: Add dump of ASCII equivalent text within a comment at the 
end of each line of the output for the Buffer() ASL operator.

AcpiDump: Miscellaneous changes:
  Fixed repetitive table dump in -n mode.
  For older EFI platforms, use the ACPI 1.0 GUID during RSDP search if 
the ACPI 2.0 GUID fails.

iASL: Fixed a problem where the compiler could fault if incorrectly given 
an acpidump output file as input. ACPICA BZ 1088. David Box.

AcpiExec/AcpiNames: Fixed a problem where these utilities could fault if 
they are invoked without any arguments.

Debugger: Fixed a possible memory leak in an error return path. ACPICA BZ 
1086. Colin Ian King.

Disassembler: Cleaned up a block of code that extracts a parent Op 
object. Added a comment that explains that the parent is guaranteed to be 
valid in this case. ACPICA BZ 1069.


----------------------------------------
24 April 2014. Summary of changes for version 20140424:

1) ACPICA kernel-resident subsystem:

Implemented support to skip/ignore NULL address entries in the RSDT/XSDT. 
Some of these tables are known to contain a trailing NULL entry. Lv 
Zheng.

Removed an extraneous error message for the case where there are a large 
number of system GPEs (> 124). This was the "32-bit FADT register is too 
long to convert to GAS struct" message, which is irrelevant for GPEs 
since the GPEx_BLK_LEN fields of the FADT are always used instead of the 
(limited capacity) GAS bit length. Also, several changes to ensure proper 
support for GPE numbers > 255, where some "GPE number" fields were 8-bits 
internally.

Implemented and deployed additional configuration support for the public 
ACPICA external interfaces. Entire classes of interfaces can now be 
easily modified or configured out, replaced by stubbed inline functions 
by default. Lv Zheng.

Moved all public ACPICA runtime configuration globals to the public 
ACPICA external interface file for convenience. Also, removed some 
obsolete/unused globals. See the file acpixf.h. Lv Zheng.

Documentation: Added a new section to the ACPICA reference describing the 
maximum number of GPEs that can be supported by the FADT-defined GPEs in 
block zero and one. About 1200 total. See section 4.4.1 of the ACPICA 
reference.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a much larger code and data size.

  Current Release:
    Non-Debug Version:  96.8K Code, 27.2K Data, 124.0K Total
    Debug Version:     189.5K Code, 79.7K Data, 269.2K Total
  Previous Release:
    Non-Debug Version:  97.0K Code, 27.2K Data, 124.2K Total
    Debug Version:     189.7K Code, 79.5K Data, 269.2K Total


2) iASL Compiler/Disassembler and Tools:

iASL and disassembler: Add full support for the LPIT table (Low Power 
Idle Table). Includes support in the disassembler, data table compiler, 
and template generator.

AcpiDump utility:
1) Add option to force the use of the RSDT (over the XSDT).
2) Improve validation of the RSDP signature (use 8 chars instead of 4).

iASL: Add check for predefined packages that are too large.  For 
predefined names that contain subpackages, check if each subpackage is 
too large. (Check for too small already exists.)

Debugger: Updated the GPE command (which simulates a GPE by executing the 
GPE code paths in ACPICA). The GPE device is now optional, and defaults 
to the GPE 0/1 FADT-defined blocks.

Unix application OSL: Update line-editing support. Add additional error 
checking and take care not to reset terminal attributes on exit if they 
were never set. This should help guarantee that the terminal is always 
left in the previous state on program exit.


----------------------------------------
25 March 2014. Summary of changes for version 20140325:

1) ACPICA kernel-resident subsystem:

Updated the auto-serialize feature for control methods. This feature 
automatically serializes all methods that create named objects in order 
to prevent runtime errors. The update adds support to ignore the 
currently executing AML SyncLevel when invoking such a method, in order 
to prevent disruption of any existing SyncLevel priorities that may exist 
in the AML code. Although the use of SyncLevels is relatively rare, this 
change fixes a regression where an AE_AML_MUTEX_ORDER exception can 
appear on some machines starting with the 20140214 release.

Added a new external interface to allow the host to install ACPI tables 
very early, before the namespace is even created. AcpiInstallTable gives 
the host additional flexibility for ACPI table management. Tables can be 
installed directly by the host as if they had originally appeared in the 
XSDT/RSDT. Installed tables can be SSDTs or other ACPI data tables 
(anything except the DSDT and FACS). Adds a new file, tbdata.c, along 
with additional internal restructuring and cleanup. See the ACPICA 
Reference for interface details. Lv Zheng.

Added validation of the checksum for all incoming dynamically loaded 
tables (via external interfaces or via AML Load/LoadTable operators). Lv 
Zheng.

Updated the use of the AcpiOsWaitEventsComplete interface during Notify 
and GPE handler removal. Restructured calls to eliminate possible race 
conditions. Lv Zheng.

Added a warning for the use/execution of the ASL/AML Unload (table) 
operator. This will help detect and identify machines that use this 
operator if and when it is ever used. This operator has never been seen 
in the field and the usage model and possible side-effects of the drastic 
runtime action of a full table removal are unknown.

Reverted the use of #pragma push/pop which was introduced in the 20140214 
release. It appears that push and pop are not implemented by enough 
compilers to make the use of this feature feasible for ACPICA at this 
time. However, these operators may be deployed in a future ACPICA 
release.

Added the missing EXPORT_SYMBOL macros for the install and remove SCI 
handler interfaces.

Source code generation:
1) Disabled the use of the "strchr" macro for the gcc-specific 
generation. For some versions of gcc, this macro can periodically expose 
a compiler bug which in turn causes compile-time error(s).
2) Added support for PPC64 compilation. Colin Ian King.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a much larger code and data size.

  Current Release:
    Non-Debug Version:  97.0K Code, 27.2K Data, 124.2K Total
    Debug Version:     189.7K Code, 79.5K Data, 269.2K Total
  Previous Release:
    Non-Debug Version:  96.5K Code, 27.2K Data, 123.7K Total
    Debug Version:     188.6K Code, 79.0K Data, 267.6K Total


2) iASL Compiler/Disassembler and Tools:

Disassembler: Added several new features to improve the readability of 
the resulting ASL code. Extra information is emitted within comment 
fields in the ASL code:
1) Known _HID/_CID values are decoded to descriptive text.
2) Standard values for the Notify() operator are decoded to descriptive 
text.
3) Target operands are expanded to full pathnames (in a comment) when 
possible.

Disassembler: Miscellaneous updates for extern() handling:
1) Abort compiler if file specified by -fe option does not exist.
2) Silence unnecessary warnings about argument count mismatches.
3) Update warning messages concerning unresolved method externals.
4) Emit "UnknownObj" keyword for externals whose type cannot be 
determined.

AcpiHelp utility:
1) Added the -a option to display both the ASL syntax and the AML 
encoding for an input ASL operator. This effectively displays all known 
information about an ASL operator with one AcpiHelp invocation.
2) Added substring match support (similar to a wildcard) for the -i 
(_HID/PNP IDs) option.

iASL/Disassembler: Since this tool does not yet support execution on big-
endian machines, added detection of endianness and an error message if 
execution is attempted on big-endian. Support for big-endian within iASL 
is a feature that is on the ACPICA to-be-done list.

AcpiBin utility:
1) Remove option to extract binary files from an acpidump; this function 
is made obsolete by the AcpiXtract utility.
2) General cleanup of open files and allocated buffers.


----------------------------------------
14 February 2014. Summary of changes for version 20140214:

1) ACPICA kernel-resident subsystem:

Implemented a new mechanism to proactively prevent problems with ill-
behaved reentrant control methods that create named ACPI objects. This 
behavior is illegal as per the ACPI specification, but is nonetheless 
frequently seen in the field. Previously, this could lead to an 
AE_ALREADY_EXISTS exception if the method was actually entered by more 
than one thread. This new mechanism detects such methods at table load 
time and marks them "serialized" to prevent reentrancy. A new global 
option, AcpiGbl_AutoSerializeMethods, has been added to disable this 
feature if desired. This mechanism and global option obsoletes and 
supersedes the previous AcpiGbl_SerializeAllMethods option.

Added the "Windows 2013" string to the _OSI support. ACPICA will now 
respond TRUE to _OSI queries with this string. It is the stated policy of 
ACPICA to add new strings to the _OSI support as soon as possible after 
they are defined. See the full ACPICA _OSI policy which has been added to 
the utilities/utosi.c file.

Hardened/updated the _PRT return value auto-repair code:
1) Do not abort the repair on a single subpackage failure, continue to 
check all subpackages.
2) Add check for the minimum subpackage length (4).
3) Properly handle extraneous NULL package elements.

Added support to avoid the possibility of infinite loops when traversing 
object linked lists. Never allow an infinite loop, even in the face of 
corrupted object lists.

ACPICA headers: Deployed the use of #pragma pack(push) and #pragma 
pack(pop) directives to ensure that the ACPICA headers are independent of 
compiler settings or other host headers.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a much larger code and data size.

  Current Release:
    Non-Debug Version:  96.5K Code, 27.2K Data, 123.7K Total
    Debug Version:     188.6K Code, 79.0K Data, 267.6K Total
  Previous Release:
    Non-Debug Version:  96.2K Code, 27.0K Data, 123.2K Total
    Debug Version:     187.5K Code, 78.3K Data, 265.8K Total


2) iASL Compiler/Disassembler and Tools:

iASL/Table-compiler: Fixed a problem with support for the SPMI table. The 
first reserved field was incorrectly forced to have a value of zero. This 
change correctly forces the field to have a value of one. ACPICA BZ 1081.

Debugger: Added missing support for the "Extra" and "Data" subobjects 
when displaying object data.

Debugger: Added support to display entire object linked lists when 
displaying object data.

iASL: Removed the obsolete -g option to obtain ACPI tables from the 
Windows registry. This feature has been superseded by the acpidump 
utility. 


----------------------------------------
14 January 2014. Summary of changes for version 20140114:

1) ACPICA kernel-resident subsystem:

Updated all ACPICA copyrights and signons to 2014. Added the 2014 
copyright to all module headers and signons, including the standard Linux 
header. This affects virtually every file in the ACPICA core subsystem, 
iASL compiler, all ACPICA utilities, and the test suites.

Improved parameter validation for AcpiInstallGpeBlock. Added the 
following checks:
1) The incoming device handle refers to type ACPI_TYPE_DEVICE.
2) There is not already a GPE block attached to the device.
Likewise, with AcpiRemoveGpeBlock, ensure that the incoming object is a 
device.

Correctly support "references" in the ACPI_OBJECT. This change fixes the 
support to allow references (namespace nodes) to be passed as arguments 
to control methods via the evaluate object interface. This is probably 
most useful for testing purposes, however.

Improved support for 32/64 bit physical addresses in printf()-like 
output. This change improves the support for physical addresses in printf 
debug statements and other output on both 32-bit and 64-bit hosts. It 
consistently outputs the appropriate number of bytes for each host. The 
%p specifier is unsatisfactory since it does not emit uniform output on 
all hosts/clib implementations (on some, leading zeros are not supported, 
leading to difficult-to-read output).

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a much larger code and data size.

  Current Release:
    Non-Debug Version:  96.2K Code, 27.0K Data, 123.2K Total

2) iASL Compiler/Disassembler and Tools:

iASL: Fix a possible fault when using the Connection() operator. Fixes a 
problem if the parent Field definition for the Connection operator refers 
to an operation region that does not exist. ACPICA BZ 1064.

AcpiExec: Load of local test tables is now optional. The utility has the 
capability to load some various tables to test features of ACPICA. 
However, there are enough of them that the output of the utility became 
confusing. With this change, only the required local tables are displayed 
(RSDP, XSDT, etc.) along with the actual tables loaded via the command 
line specification. This makes the default output simler and easier to 
understand. The -el command line option restores the original behavior 
for testing purposes.

AcpiExec: Added support for overlapping operation regions. This change 
expands the simulation of operation regions by supporting regions that 
overlap within the given address space. Supports SystemMemory and 
SystemIO. ASLTS test suite updated also. David Box. ACPICA BZ 1031.

AcpiExec: Added region handler support for PCI_Config and EC spaces. This 
allows AcpiExec to simulate these address spaces, similar to the current 
support for SystemMemory and SystemIO.

Debugger: Added new command to read/write/compare all namespace objects. 
The command "test objects" will exercise the entire namespace by writing 
new values to each data object, and ensuring that the write was 
successful. The original value is then restored and verified.

Debugger: Added the "test predefined" command. This change makes this 
test public and puts it under the new "test" command. The test executes 
each and every predefined name within the current namespace.


----------------------------------------
18 December 2013. Summary of changes for version 20131218:

Global note: The ACPI 5.0A specification was released this month. There 
are no changes needed for ACPICA since this release of ACPI is an 
errata/clarification release. The specification is available at 
acpi.info. 


1) ACPICA kernel-resident subsystem:

Added validation of the XSDT root table if it is present. Some older 
platforms contain an XSDT that is ill-formed or otherwise invalid (such 
as containing some or all entries that are NULL pointers). This change 
adds a new function to validate the XSDT before actually using it. If the 
XSDT is found to be invalid, ACPICA will now automatically fall back to 
using the RSDT instead. Original implementation by Zhao Yakui. Ported to 
ACPICA and enhanced by Lv Zheng and Bob Moore.

Added a runtime option to ignore the XSDT and force the use of the RSDT. 
This change adds a runtime option that will force ACPICA to use the RSDT 
instead of the XSDT (AcpiGbl_DoNotUseXsdt). Although the ACPI spec 
requires that an XSDT be used instead of the RSDT, the XSDT has been 
found to be corrupt or ill-formed on some machines. Lv Zheng.

Added a runtime option to favor 32-bit FADT register addresses over the 
64-bit addresses. This change adds an option to favor 32-bit FADT 
addresses when there is a conflict between the 32-bit and 64-bit versions 
of the same register. The default behavior is to use the 64-bit version 
in accordance with the ACPI specification. This can now be overridden via 
the AcpiGbl_Use32BitFadtAddresses flag. ACPICA BZ 885. Lv Zheng.

During the change above, the internal "Convert FADT" and "Verify FADT" 
functions have been merged to simplify the code, making it easier to 
understand and maintain. ACPICA BZ 933.

Improve exception reporting and handling for GPE block installation. 
Return an actual status from AcpiEvGetGpeXruptBlock and don't clobber the 
status when exiting AcpiEvInstallGpeBlock. ACPICA BZ 1019.

Added helper macros to extract bus/segment numbers from the HEST table. 
This change adds two macros to extract the encoded bus and segment 
numbers from the HEST Bus field - ACPI_HEST_BUS and ACPI_HEST_SEGMENT. 
Betty Dall <betty.dall@hp.com>

Removed the unused ACPI_FREE_BUFFER macro. This macro is no longer used 
by ACPICA. It is not a public macro, so it should have no effect on 
existing OSV code. Lv Zheng.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a much larger code and data size.

  Current Release:
    Non-Debug Version:  96.1K Code, 27.0K Data, 123.1K Total
    Debug Version:     185.6K Code, 77.3K Data, 262.9K Total
  Previous Release:
    Non-Debug Version:  95.9K Code, 27.0K Data, 122.9K Total
    Debug Version:     185.1K Code, 77.2K Data, 262.3K Total


2) iASL Compiler/Disassembler and Tools:

Disassembler: Improved pathname support for emitted External() 
statements. This change adds full pathname support for external names 
that have been resolved internally by the inclusion of additional ACPI 
tables (via the iASL -e option). Without this change, the disassembler 
can emit multiple externals for the same object, or it become confused 
when the Scope() operator is used on an external object. Overall, greatly 
improves the ability to actually recompile the emitted ASL code when 
objects a referenced across multiple ACPI tables. Reported by Michael 
Tsirkin (mst@redhat.com).

Tests/ASLTS: Updated functional control suite to execute with no errors. 
David Box. Fixed several errors related to the testing of the interpreter 
slack mode. Lv Zheng.

iASL: Added support to detect names that are declared within a control 
method, but are unused (these are temporary names that are only valid 
during the time the method is executing). A remark is issued for these 
cases. ACPICA BZ 1022.

iASL: Added full support for the DBG2 table. Adds full disassembler, 
table compiler, and template generator support for the DBG2 table (Debug 
Port 2 table).

iASL: Added full support for the PCCT table, update the table definition. 
Updates the PCCT table definition in the actbl3.h header and adds table 
compiler and template generator support.

iASL: Added an option to emit only error messages (no warnings/remarks). 
The -ve option will enable only error messages, warnings and remarks are 
suppressed. This can simplify debugging when only the errors are 
important, such as when an ACPI table is disassembled and there are many 
warnings and remarks -- but only the actual errors are of real interest.

Example ACPICA code (source/tools/examples): Updated the example code so 
that it builds to an actual working program, not just example code. Added 
ACPI tables and execution of an example control method in the DSDT. Added 
makefile support for Unix generation.


----------------------------------------
15 November 2013. Summary of changes for version 20131115:

This release is available at https://acpica.org/downloads


1) ACPICA kernel-resident subsystem:

Resource Manager: Fixed loop termination for the "get AML length" 
function. The loop previously had an error termination on a NULL resource 
pointer, which can never happen since the loop simply increments a valid 
resource pointer. This fix changes the loop to terminate with an error on 
an invalid end-of-buffer condition. The problem can be seen as an 
infinite loop by callers to AcpiSetCurrentResources with an invalid or 
corrupted resource descriptor, or a resource descriptor that is missing 
an END_TAG descriptor. Reported by Dan Carpenter 
<dan.carpenter@oracle.com>. Lv Zheng, Bob Moore.

Table unload and ACPICA termination: Delete all attached data objects 
during namespace node deletion. This fix updates namespace node deletion 
to delete the entire list of attached objects (attached via 
AcpiAttachObject) instead of just one of the attached items. ACPICA BZ 
1024. Tomasz Nowicki (tomasz.nowicki@linaro.org).

ACPICA termination: Added support to delete all objects attached to the 
root namespace node. This fix deletes any and all objects that have been 
attached to the root node via AcpiAttachData. Previously, none of these 
objects were deleted. Reported by Tomasz Nowicki. ACPICA BZ 1026.

Debug output: Do not emit the function nesting level for the in-kernel 
build. The nesting level is really only useful during a single-thread 
execution. Therefore, only enable this output for the AcpiExec utility. 
Also, only emit the thread ID when executing under AcpiExec (Context 
switches are still always detected and a message is emitted). ACPICA BZ 
972.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a much larger code and data size.

  Current Release:
    Non-Debug Version:  95.9K Code, 27.0K Data, 122.9K Total
    Debug Version:     185.1K Code, 77.2K Data, 262.3K Total
  Previous Release:
    Non-Debug Version:  95.8K Code, 27.0K Data, 122.8K Total
    Debug Version:     185.2K Code, 77.2K Data, 262.4K Total


2) iASL Compiler/Disassembler and Tools:

AcpiExec/Unix-OSL: Use <termios.h> instead of <termio.h>. This is the 
correct portable POSIX header for terminal control functions.

Disassembler: Fixed control method invocation issues related to the use 
of the CondRefOf() operator. The problem is seen in the disassembly where 
control method invocations may not be disassembled properly if the 
control method name has been used previously as an argument to CondRefOf. 
The solution is to not attempt to emit an external declaration for the 
CondRefOf target (it is not necessary in the first place). This prevents 
disassembler object type confusion. ACPICA BZ 988.

Unix Makefiles: Added an option to disable compiler optimizations and the 
_FORTIFY_SOURCE flag. Some older compilers have problems compiling ACPICA 
with optimizations (reportedly, gcc 4.4 for example). This change adds a 
command line option for make (NOOPT) that disables all compiler 
optimizations and the _FORTIFY_SOURCE compiler flag. The default 
optimization is -O2 with the _FORTIFY_SOURCE flag specified. ACPICA BZ 
1034. Lv Zheng, Bob Moore.

Tests/ASLTS: Added options to specify individual test cases and modes. 
This allows testers running aslts.sh to optionally specify individual 
test modes and test cases. Also added an option to disable the forced 
generation of the ACPICA tools from source if desired. Lv Zheng.

----------------------------------------
27 September 2013. Summary of changes for version 20130927:

This release is available at https://acpica.org/downloads


1) ACPICA kernel-resident subsystem:

Fixed a problem with store operations to reference objects. This change 
fixes a problem where a Store operation to an ArgX object that contained 
a 
reference to a field object did not complete the automatic dereference 
and 
then write to the actual field object. Instead, the object type of the 
field object was inadvertently changed to match the type of the source 
operand. The new behavior will actually write to the field object (buffer 
field or field unit), thus matching the correct ACPI-defined behavior.

Implemented support to allow the host to redefine individual OSL 
prototypes. This change enables the host to redefine OSL prototypes found 
in the acpiosxf.h file. This allows the host to implement OSL interfaces 
with a macro or inlined function. Further, it allows the host to add any 
additional required modifiers such as __iomem, __init, __exit, etc., as 
necessary on a per-interface basis. Enables maximum flexibility for the 
OSL interfaces. Lv Zheng.

Hardcoded the access width for the FADT-defined reset register. The ACPI 
specification requires the reset register width to be 8 bits. ACPICA now 
hardcodes the width to 8 and ignores the FADT width value. This provides 
compatibility with other ACPI implementations that have allowed BIOS code 
with bad register width values to go unnoticed. Matthew Garett, Bob 
Moore, 
Lv Zheng.

Changed the position/use of the ACPI_PRINTF_LIKE macro. This macro is 
used 
in the OSL header (acpiosxf). The change modifies the position of this 
macro in each instance where it is used (AcpiDebugPrint, etc.) to avoid 
build issues if the OSL defines the implementation of the interface to be 
an inline stub function. Lv Zheng.

Deployed a new macro ACPI_EXPORT_SYMBOL_INIT for the main ACPICA 
initialization interfaces. This change adds a new macro for the main init 
and terminate external interfaces in order to support hosts that require 
additional or different processing for these functions. Changed from 
ACPI_EXPORT_SYMBOL to ACPI_EXPORT_SYMBOL_INIT for these functions. Lv 
Zheng, Bob Moore.

Cleaned up the memory allocation macros for configurability. In the 
common 
case, the ACPI_ALLOCATE and related macros now resolve directly to their 
respective AcpiOs* OSL interfaces. Two options:
1) The ACPI_ALLOCATE_ZEROED macro uses a simple local implementation by 
default, unless overridden by the USE_NATIVE_ALLOCATE_ZEROED define.
2) For AcpiExec (and for debugging), the macros can optionally be 
resolved 
to the local ACPICA interfaces that track each allocation (local tracking 
is used to immediately detect memory leaks).
Lv Zheng.

Simplified the configuration for ACPI_REDUCED_HARDWARE. Allows the kernel 
to predefine this macro to either TRUE or FALSE during the system build.

Replaced __FUNCTION_ with __func__ in the gcc-specific header.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a much larger code and data size.

  Current Release:
    Non-Debug Version:  95.8K Code, 27.0K Data, 122.8K Total
    Debug Version:     185.2K Code, 77.2K Data, 262.4K Total
  Previous Release:
    Non-Debug Version:  96.7K Code, 27.1K Data, 123.9K Total
    Debug Version:     184.4K Code, 76.8K Data, 261.2K Total


2) iASL Compiler/Disassembler and Tools:

iASL: Implemented wildcard support for the -e option. This simplifies use 
when there are many SSDTs that must be included to resolve external 
method 
declarations. ACPICA BZ 1041. Example:
    iasl -e ssdt*.dat -d dsdt.dat

AcpiExec: Add history/line-editing for Unix/Linux systems. This change 
adds a portable module that implements full history and limited line 
editing for Unix and Linux systems. It does not use readline() due to 
portability issues. Instead it uses the POSIX termio interface to put the 
terminal in raw input mode so that the various special keys can be 
trapped 
(such as up/down-arrow for history support and left/right-arrow for line 
editing). Uses the existing debugger history mechanism. ACPICA BZ 1036.

AcpiXtract: Add support to handle (ignore) "empty" lines containing only 
one or more spaces. This provides compatible with early or different 
versions of the AcpiDump utility. ACPICA BZ 1044.

AcpiDump: Do not ignore tables that contain only an ACPI table header. 
Apparently, some BIOSs create SSDTs that contain an ACPI table header but 
no other data. This change adds support to dump these tables. Any tables 
shorter than the length of an ACPI table header remain in error (an error 
message is emitted). Reported by Yi Li.

Debugger: Echo actual command along with the "unknown command" message.

----------------------------------------
23 August 2013. Summary of changes for version 20130823:

1) ACPICA kernel-resident subsystem:

Implemented support for host-installed System Control Interrupt (SCI) 
handlers. Certain ACPI functionality requires the host to handle raw 
SCIs. For example, the "SCI Doorbell" that is defined for memory power 
state support requires the host device driver to handle SCIs to examine 
if the doorbell has been activated. Multiple SCI handlers can be 
installed to allow for future expansion. New external interfaces are 
AcpiInstallSciHandler, AcpiRemoveSciHandler; see the ACPICA reference for 
details. Lv Zheng, Bob Moore. ACPICA BZ 1032.

Operation region support: Never locally free the handler "context" 
pointer. This change removes some dangerous code that attempts to free 
the handler context pointer in some (rare) circumstances. The owner of 
the handler owns this pointer and the ACPICA code should never touch it. 
Although not seen to be an issue in any kernel, it did show up as a 
problem (fault) under AcpiExec. Also, set the internal storage field for 
the context pointer to zero when the region is deactivated, simply for 
sanity. David Box. ACPICA BZ 1039.

AcpiRead: On error, do not modify the return value target location. If an 
error happens in the middle of a split 32/32 64-bit I/O operation, do not 
modify the target of the return value pointer. Makes the code consistent 
with the rest of ACPICA. Bjorn Helgaas.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a much larger code and data size.

  Current Release:
    Non-Debug Version:  96.7K Code, 27.1K Data, 123.9K Total
    Debug Version:     184.4K Code, 76.8K Data, 261.2K Total
  Previous Release:
    Non-Debug Version:  96.2K Code, 27.1K Data, 123.3K Total
    Debug Version:     185.4K Code, 77.1K Data, 262.5K Total


2) iASL Compiler/Disassembler and Tools:

AcpiDump: Implemented several new features and fixed some problems:
1) Added support to dump the RSDP, RSDT, and XSDT tables.
2) Added support for multiple table instances (SSDT, UEFI).
3) Added option to dump "customized" (overridden) tables (-c).
4) Fixed a problem where some table filenames were improperly 
constructed.
5) Improved some error messages, removed some unnecessary messages.

iASL: Implemented additional support for disassembly of ACPI tables that 
contain invocations of external control methods. The -fe<file> option 
allows the import of a file that specifies the external methods along 
with the required number of arguments for each -- allowing for the 
correct disassembly of the table. This is a workaround for a limitation 
of AML code where the disassembler often cannot determine the number of 
arguments required for an external control method and generates incorrect 
ASL code. See the iASL reference for details. ACPICA BZ 1030.

Debugger: Implemented a new command (paths) that displays the full 
pathnames (namepaths) and object types of all objects in the namespace. 
This is an alternative to the namespace command.

Debugger: Implemented a new command (sci) that invokes the SCI dispatch 
mechanism and any installed handlers.

iASL: Fixed a possible segfault for "too many parent prefixes" condition. 
This can occur if there are too many parent prefixes in a namepath (for 
example, ^^^^^^PCI0.ECRD). ACPICA BZ 1035.

Application OSLs: Set the return value for the PCI read functions. These 
functions simply return AE_OK, but should set the return value to zero 
also. This change implements this. ACPICA BZ 1038.

Debugger: Prevent possible command line buffer overflow. Increase the 
size of a couple of the debugger line buffers, and ensure that overflow 
cannot happen. ACPICA BZ 1037.

iASL: Changed to abort immediately on serious errors during the parsing 
phase. Due to the nature of ASL, there is no point in attempting to 
compile these types of errors, and they typically end up causing a 
cascade of hundreds of errors which obscure the original problem.

----------------------------------------
25 July 2013. Summary of changes for version 20130725:

1) ACPICA kernel-resident subsystem:

Fixed a problem with the DerefOf operator where references to FieldUnits 
and BufferFields incorrectly returned the parent object, not the actual 
value of the object. After this change, a dereference of a FieldUnit 
reference results in a read operation on the field to get the value, and 
likewise, the appropriate BufferField value is extracted from the target 
buffer.

Fixed a problem where the _WAK method could cause a fault under these 
circumstances: 1) Interpreter slack mode was not enabled, and 2) the _WAK 
method returned no value. The problem is rarely seen because most kernels 
run ACPICA in slack mode.

For the DerefOf operator, a fatal error now results if an attempt is made 
to dereference a reference (created by the Index operator) to a NULL 
package element. Provides compatibility with other ACPI implementations, 
and this behavior will be added to a future version of the ACPI 
specification.

The ACPI Power Management Timer (defined in the FADT) is now optional. 
This provides compatibility with other ACPI implementations and will 
appear in the next version of the ACPI specification. If there is no PM 
Timer on the platform, AcpiGetTimer returns AE_SUPPORT. An address of 
zero in the FADT indicates no PM timer.

Implemented a new interface for _OSI support, AcpiUpdateInterfaces. This 
allows the host to globally enable/disable all vendor strings, all 
feature strings, or both. Intended to be primarily used for debugging 
purposes only. Lv Zheng.

Expose the collected _OSI data to the host via a global variable. This 
data tracks the highest level vendor ID that has been invoked by the BIOS 
so that the host (and potentially ACPICA itself) can change behaviors 
based upon the age of the BIOS.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a much larger code and data size.

  Current Release:
    Non-Debug Version:  96.2K Code, 27.1K Data, 123.3K Total
    Debug Version:     184.4K Code, 76.8K Data, 261.2K Total
  Previous Release:
    Non-Debug Version:  95.9K Code, 26.9K Data, 122.8K Total
    Debug Version:     184.1K Code, 76.7K Data, 260.8K Total


2) iASL Compiler/Disassembler and Tools:

iASL: Created the following enhancements for the -so option (create 
offset table):
1)Add offsets for the last nameseg in each namepath for every supported 
object type
2)Add support for Processor, Device, Thermal Zone, and Scope objects
3)Add the actual AML opcode for the parent object of every supported 
object type
4)Add support for the ZERO/ONE/ONES AML opcodes for integer objects

Disassembler: Emit all unresolved external symbols in a single block. 
These are external references to control methods that could not be 
resolved, and thus, the disassembler had to make a guess at the number of 
arguments to parse.

iASL: The argument to the -T option (create table template) is now 
optional. If not specified, the default table is a DSDT, typically the 
most common case.

----------------------------------------
26 June 2013. Summary of changes for version 20130626:

1) ACPICA kernel-resident subsystem:

Fixed an issue with runtime repair of the _CST object. Null or invalid 
elements were not always removed properly. Lv Zheng. 

Removed an arbitrary restriction of 256 GPEs per GPE block (such as the 
FADT-defined GPE0 and GPE1). For GPE0, GPE1, and each GPE Block Device, 
the maximum number of GPEs is 1016. Use of multiple GPE block devices 
makes the system-wide number of GPEs essentially unlimited.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a much larger code and data size.

  Current Release:
    Non-Debug Version:  95.9K Code, 26.9K Data, 122.8K Total
    Debug Version:     184.1K Code, 76.7K Data, 260.8K Total
  Previous Release:
    Non-Debug Version:  96.0K Code, 27.0K Data, 123.0K Total
    Debug Version:     184.1K Code, 76.8K Data, 260.9K Total


2) iASL Compiler/Disassembler and Tools:

Portable AcpiDump: Implemented full support for the Linux and FreeBSD 
hosts. Now supports Linux, FreeBSD, and Windows.

Disassembler: Added some missing types for the HEST and EINJ tables: "Set 
Error Type With Address", "CMCI", "MCE", and "Flush Cacheline".

iASL/Preprocessor: Implemented full support for nested 
#if/#else/#elif/#endif blocks. Allows arbitrary depth of nested blocks.

Disassembler: Expanded maximum output string length to 64K. Was 256 bytes 
max. The original purpose of this constraint was to limit the amount of 
debug output. However, the string function in question (UtPrintString) is 
now used for the disassembler also, where 256 bytes is insufficient. 
Reported by RehabMan@GitHub.

iASL/DataTables: Fixed some problems and issues with compilation of DMAR 
tables. ACPICA BZ 999. Lv Zheng.

iASL: Fixed a couple of error exit issues that could result in a "Could 
not delete <file>" message during ASL compilation.

AcpiDump: Allow "FADT" and "MADT" as valid table signatures, even though 
the actual signatures for these tables are "FACP" and "APIC", 
respectively.

AcpiDump: Added support for multiple UEFI tables. Only SSDT and UEFI 
tables are allowed to have multiple instances.

----------------------------------------
17 May 2013. Summary of changes for version 20130517:

1) ACPICA kernel-resident subsystem:

Fixed a regression introduced in version 20130328 for _INI methods. This 
change fixes a problem introduced in 20130328 where _INI methods are no 
longer executed properly because of a memory block that was not 
initialized correctly. ACPICA BZ 1016. Tomasz Nowicki 
<tomasz.nowicki@linaro.org>.

Fixed a possible problem with the new extended sleep registers in the 
ACPI 
5.0 FADT. Do not use these registers (even if populated) unless the HW-
reduced bit is set in the FADT (as per the ACPI specification). ACPICA BZ 
1020. Lv Zheng.

Implemented return value repair code for _CST predefined objects: Sort 
the 
list and detect/remove invalid entries. ACPICA BZ 890. Lv Zheng.

Implemented a debug-only option to disable loading of SSDTs from the 
RSDT/XSDT during ACPICA initialization. This can be useful for debugging 
ACPI problems on some machines. Set AcpiGbl_DisableSsdtTableLoad in 
acglobal.h - ACPICA BZ 1005. Lv Zheng.

Fixed some issues in the ACPICA initialization and termination code: 
Tomasz Nowicki <tomasz.nowicki@linaro.org>
1) Clear events initialized flag upon event component termination. ACPICA 
BZ 1013.
2) Fixed a possible memory leak in GPE init error path. ACPICA BZ 1018. 
3) Delete global lock pending lock during termination. ACPICA BZ 1012.
4) Clear debug buffer global on termination to prevent possible multiple 
delete. ACPICA BZ 1010.

Standardized all switch() blocks across the entire source base. After 
many 
years, different formatting for switch() had crept in. This change makes 
the formatting of every switch block identical. ACPICA BZ 997. Chao Guan.

Split some files to enhance ACPICA modularity and configurability:
1) Split buffer dump routines into utilities/utbuffer.c
2) Split internal error message routines into utilities/uterror.c
3) Split table print utilities into tables/tbprint.c
4) Split iASL command-line option processing into asloptions.c

Makefile enhancements:
1) Support for all new files above.
2) Abort make on errors from any subcomponent. Chao Guan.
3) Add build support for Apple Mac OS X. Liang Qi.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and

    Debug Version:     183.5K Code, 76.6K Data, 260.1K Total


2) iASL Compiler/Disassembler and Tools:

New utility: Implemented an easily portable version of the acpidump 
utility to extract ACPI tables from the system (or a file) in an ASCII 
hex 
dump format. The top-level code implements the various command line 
options, file I/O, and table dump routines. To port to a new host, only 
three functions need to be implemented to get tables -- since this 
functionality is OS-dependent. See the tools/acpidump/apmain.c module and 
the ACPICA reference for porting instructions. ACPICA BZ 859. Notes:
1) The Windows version obtains the ACPI tables from the Registry.
2) The Linux version is under development.
3) Other hosts - If an OS-dependent module is submitted, it will be 
distributed with ACPICA.

iASL: Fixed a regression for -D preprocessor option (define symbol). A 
restructuring/change to the initialization sequence caused this option to 
no longer work properly.

iASL: Implemented a mechanism to disable specific warnings and remarks. 
Adds a new command line option, "-vw <messageid> as well as "#pragma 
disable <messageid>". ACPICA BZ 989. Chao Guan, Bob Moore.

iASL: Fix for too-strict package object validation. The package object 
validation for return values from the predefined names is a bit too 
strict, it does not allow names references within the package (which will 
be resolved at runtime.) These types of references cannot be validated at 
compile time. This change ignores named references within package objects 
for names that return or define static packages.

Debugger: Fixed the 80-character command line limitation for the History 
command. Now allows lines of arbitrary length. ACPICA BZ 1000. Chao Guan.

iASL: Added control method and package support for the -so option 
(generates AML offset table for BIOS support.)

iASL: issue a remark if a non-serialized method creates named objects. If 
a thread blocks within the method for any reason, and another thread 
enters the method, the method will fail because an attempt will be made 
to 
create the same (named) object twice. In this case, issue a remark that 
the method should be marked serialized. NOTE: may become a warning later. 
ACPICA BZ 909.

----------------------------------------
18 April 2013. Summary of changes for version 20130418:

1) ACPICA kernel-resident subsystem:

Fixed a possible buffer overrun during some rare but specific field unit 
read operations. This overrun can only happen if the DSDT version is 1 -- 
meaning that all AML integers are 32 bits -- and the field length is 
between 33 and 55 bits long. During the read, an internal buffer object 
is 
created for the field unit because the field is larger than an integer 
(32 
bits). However, in this case, the buffer will be incorrectly written 
beyond the end because the buffer length is less than the internal 
minimum 
of 64 bits (8 bytes) long. The buffer will be either 5, 6, or 7 bytes 
long, but a full 8 bytes will be written.

Updated the Embedded Controller "orphan" _REG method support. This refers 
to _REG methods under the EC device that have no corresponding operation 
region. This is allowed by the ACPI specification. This update removes a 
dependency on the existence an ECDT table. It will execute an orphan _REG 
method as long as the operation region handler for the EC is installed at 
the EC device node and not the namespace root. Rui Zhang (original 
update), Bob Moore (update/integrate).

Implemented run-time argument typechecking for all predefined ACPI names 
(_STA, _BIF, etc.) This change performs object typechecking on all 
incoming arguments for all predefined names executed via 
AcpiEvaluateObject. This ensures that ACPI-related device drivers are 
passing correct object types as well as the correct number of arguments 
(therefore identifying any issues immediately). Also, the ASL/namespace 
definition of the predefined name is checked against the ACPI 
specification for the proper argument count. Adds one new file, 
nsarguments.c

Changed an exception code for the ASL UnLoad() operator. Changed the 
exception code for the case where the input DdbHandle is invalid, from 
AE_BAD_PARAMETER to the more appropriate AE_AML_OPERAND_TYPE.

Unix/Linux makefiles: Removed the use of the -O2 optimization flag in the 
global makefile. The use of this flag causes compiler errors on earlier 
versions of GCC, so it has been removed for compatibility.

Miscellaneous cleanup:
1) Removed some unused/obsolete macros
2) Fixed a possible memory leak in the _OSI support
3) Removed an unused variable in the predefined name support
4) Windows OSL: remove obsolete reference to a memory list field

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a much larger code and data size.

  Current Release:
    Non-Debug Version:  95.2K Code, 26.4K Data, 121.6K Total
    Debug Version:     183.0K Code, 76.0K Data, 259.0K Total
  Previous Release:
    Non-Debug Version:  95.6K Code, 26.8K Data, 122.4K Total
    Debug Version:     183.5K Code, 76.6K Data, 260.1K Total


2) iASL Compiler/Disassembler and Tools:

AcpiExec: Added installation of a handler for the SystemCMOS address 
space. This prevents control method abort if a method accesses this 
space.

AcpiExec: Added support for multiple EC devices, and now install EC 
operation region handler(s) at the actual EC device instead of the 
namespace root. This reflects the typical behavior of host operating 
systems.

AcpiExec: Updated to ensure that all operation region handlers are 
installed before the _REG methods are executed. This prevents a _REG 
method from aborting if it accesses an address space has no handler. 
AcpiExec installs a handler for every possible address space.

Debugger: Enhanced the "handlers" command to display non-root handlers. 
This change enhances the handlers command to display handlers associated 
with individual devices throughout the namespace, in addition to the 
currently supported display of handlers associated with the root 
namespace 
node.

ASL Test Suite: Several test suite errors have been identified and 
resolved, reducing the total error count during execution. Chao Guan.

----------------------------------------
28 March 2013. Summary of changes for version 20130328:

1) ACPICA kernel-resident subsystem:

Fixed several possible race conditions with the internal object reference 
counting mechanism. Some of the external ACPICA interfaces update object 
reference counts without holding the interpreter or namespace lock. This 
change adds a spinlock to protect reference count updates on the internal 
ACPICA objects. Reported by and with assistance from Andriy Gapon 
(avg@FreeBSD.org).

FADT support: Removed an extraneous warning for very large GPE register 
sets. This change removes a size mismatch warning if the legacy length 
field for a GPE register set is larger than the 64-bit GAS structure can 
accommodate. GPE register sets can be larger than the 255-bit width 
limitation of the GAS structure. Linn Crosetto (linn@hp.com).

_OSI Support: handle any errors from AcpiOsAcquireMutex. Check for error 
return from this interface. Handles a possible timeout case if 
ACPI_WAIT_FOREVER is modified by the host to be a value less than 
"forever". Jung-uk Kim.

Predefined name support: Add allowed/required argument type information 
to 
the master predefined info table. This change adds the infrastructure to 
enable typechecking on incoming arguments for all predefined 
methods/objects. It does not actually contain the code that will fully 
utilize this information, this is still under development. Also condenses 
some duplicate code for the predefined names into a new module, 
utilities/utpredef.c

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a much larger code and data size.

  Previous Release:
    Non-Debug Version:  95.0K Code, 25.9K Data, 120.9K Total
    Debug Version:     182.9K Code, 75.6K Data, 258.5K Total
  Current Release:
    Non-Debug Version:  95.2K Code, 26.4K Data, 121.6K Total
    Debug Version:     183.0K Code, 76.0K Data, 259.0K Total


2) iASL Compiler/Disassembler and Tools:

iASL: Implemented a new option to simplify the development of ACPI-
related 
BIOS code. Adds support for a new "offset table" output file. The -so 
option will create a C table containing the AML table offsets of various 
named objects in the namespace so that BIOS code can modify them easily 
at 
boot time. This can simplify BIOS runtime code by eliminating expensive 
searches for "magic values", enhancing boot times and adding greater 
reliability. With assistance from Lee Hamel.

iASL: Allow additional predefined names to return zero-length packages. 
Now, all predefined names that are defined by the ACPI specification to 
return a "variable-length package of packages" are allowed to return a 
zero length top-level package. This allows the BIOS to tell the host that 
the requested feature is not supported, and supports existing BIOS/ASL 
code and practices.

iASL: Changed the "result not used" warning to an error. This is the case 
where an ASL operator is effectively a NOOP because the result of the 
operation is not stored anywhere. For example:
    Add (4, Local0)
There is no target (missing 3rd argument), nor is the function return 
value used. This is potentially a very serious problem -- since the code 
was probably intended to do something, but for whatever reason, the value 
was not stored. Therefore, this issue has been upgraded from a warning to 
an error.

AcpiHelp: Added allowable/required argument types to the predefined names 
info display. This feature utilizes the recent update to the predefined 
names table (above).

----------------------------------------
14 February 2013. Summary of changes for version 20130214:

1) ACPICA Kernel-resident Subsystem:

Fixed a possible regression on some hosts: Reinstated the safe return 
macros (return_ACPI_STATUS, etc.) that ensure that the argument is 
evaluated only once. Although these macros are not needed for the ACPICA 
code itself, they are often used by ACPI-related host device drivers 
where 
the safe feature may be necessary.

Fixed several issues related to the ACPI 5.0 reduced hardware support 
(SOC): Now ensure that if the platform declares itself as hardware-
reduced 
via the FADT, the following functions become NOOPs (and always return 
AE_OK) because ACPI is always enabled by definition on these machines:
  AcpiEnable
  AcpiDisable
  AcpiHwGetMode
  AcpiHwSetMode

Dynamic Object Repair: Implemented additional runtime repairs for 
predefined name return values. Both of these repairs can simplify code in 
the related device drivers that invoke these methods:
1) For the _STR and _MLS names, automatically repair/convert an ASCII 
string to a Unicode buffer. 
2) For the _CRS, _PRS, and _DMA names, return a resource descriptor with 
a 
lone end tag descriptor in the following cases: A Return(0) was executed, 
a null buffer was returned, or no object at all was returned (non-slack 
mode only). Adds a new file, nsconvert.c
ACPICA BZ 998. Bob Moore, Lv Zheng.

Resource Manager: Added additional code to prevent possible infinite 
loops 
while traversing corrupted or ill-formed resource template buffers. Check 
for zero-length resource descriptors in all code that loops through 
resource templates (the length field is used to index through the 
template). This change also hardens the external AcpiWalkResources and 
AcpiWalkResourceBuffer interfaces.

Local Cache Manager: Enhanced the main data structure to eliminate an 
unnecessary mechanism to access the next object in the list. Actually 
provides a small performance enhancement for hosts that use the local 
ACPICA cache manager. Jung-uk Kim.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a much larger code and data size.

  Previous Release:
    Non-Debug Version:  94.5K Code, 25.4K Data, 119.9K Total
    Debug Version:     182.3K Code, 75.0K Data, 257.3K Total
  Current Release:
    Non-Debug Version:  95.0K Code, 25.9K Data, 120.9K Total
    Debug Version:     182.9K Code, 75.6K Data, 258.5K Total


2) iASL Compiler/Disassembler and Tools:

iASL/Disassembler: Fixed several issues with the definition of the ACPI 
5.0 RASF table (RAS Feature Table). This change incorporates late changes 
that were made to the ACPI 5.0 specification.

iASL/Disassembler: Added full support for the following new ACPI tables:
  1) The MTMR table (MID Timer Table)
  2) The VRTC table (Virtual Real Time Clock Table).
Includes header file, disassembler, table compiler, and template support 
for both tables.

iASL: Implemented compile-time validation of package objects returned by 
predefined names. This new feature validates static package objects 
returned by the various predefined names defined to return packages. Both 
object types and package lengths are validated, for both parent packages 
and sub-packages, if any. The code is similar in structure and behavior 
to 
the runtime repair mechanism within the AML interpreter and uses the 
existing predefined name information table. Adds a new file, aslprepkg.c. 
ACPICA BZ 938.

iASL: Implemented auto-detection of binary ACPI tables for disassembly. 
This feature detects a binary file with a valid ACPI table header and 
invokes the disassembler automatically. Eliminates the need to 
specifically invoke the disassembler with the -d option. ACPICA BZ 862.

iASL/Disassembler: Added several warnings for the case where there are 
unresolved control methods during the disassembly. This can potentially 
cause errors when the output file is compiled, because the disassembler 
assumes zero method arguments in these cases (it cannot determine the 
actual number of arguments without resolution/definition of the method).

Debugger: Added support to display all resources with a single command. 
Invocation of the resources command with no arguments will now display 
all 
resources within the current namespace.

AcpiHelp: Added descriptive text for each ACPICA exception code displayed 
via the -e option.

----------------------------------------
17 January 2013. Summary of changes for version 20130117:

1) ACPICA Kernel-resident Subsystem:

Updated the AcpiGetSleepTypeData interface: Allow the \_Sx methods to 
return either 1 or 2 integers. Although the ACPI spec defines the \_Sx 
objects to return a package containing one integer, most BIOS code 
returns 
two integers and the previous code reflects that. However, we also need 
to 
support BIOS code that actually implements to the ACPI spec, and this 
change reflects this.

Fixed two issues with the ACPI_DEBUG_PRINT macros:
1) Added the ACPI_DO_WHILE macro to the main DEBUG_PRINT helper macro for 
C compilers that require this support.
2) Renamed the internal ACPI_DEBUG macro to ACPI_DO_DEBUG_PRINT since 
ACPI_DEBUG is already used by many of the various hosts.

Updated all ACPICA copyrights and signons to 2013. Added the 2013 
copyright to all module headers and signons, including the standard Linux 
header. This affects virtually every file in the ACPICA core subsystem, 
iASL compiler, all ACPICA utilities, and the test suites.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a much larger code and data size.

  Previous Release:
    Non-Debug Version:  94.5K Code, 25.5K Data, 120.0K Total
    Debug Version:     182.2K Code, 74.9K Data, 257.1K Total
  Current Release:
    Non-Debug Version:  94.5K Code, 25.4K Data, 119.9K Total
    Debug Version:     182.3K Code, 75.0K Data, 257.3K Total


2) iASL Compiler/Disassembler and Tools:

Generic Unix OSL: Use a buffer to eliminate multiple vfprintf()s and 
prevent a possible fault on some hosts. Some C libraries modify the arg 
pointer parameter to vfprintf making it difficult to call it twice in the 
AcpiOsVprintf function. Use a local buffer to workaround this issue. This 
does not affect the Windows OSL since the Win C library does not modify 
the arg pointer. Chao Guan, Bob Moore.

iASL: Fixed a possible infinite loop when the maximum error count is 
reached. If an output file other than the .AML file is specified (such as 
a listing file), and the maximum number of errors is reached, do not 
attempt to flush data to the output file(s) as the compiler is aborting. 
This can cause an infinite loop as the max error count code essentially 
keeps calling itself.

iASL/Disassembler: Added an option (-in) to ignore NOOP 
opcodes/operators. 
Implemented for both the compiler and the disassembler. Often, the NOOP 
opcode is used as padding for packages that are changed dynamically by 
the 
BIOS. When disassembled and recompiled, these NOOPs will cause syntax 
errors. This option causes the disassembler to ignore all NOOP opcodes 
(0xA3), and it also causes the compiler to ignore all ASL source code 
NOOP 
statements as well.

Debugger: Enhanced the Sleep command to execute all sleep states. This 
change allows Sleep to be invoked with no arguments and causes the 
debugger to execute all of the sleep states, 0-5, automatically.

----------------------------------------
20 December 2012. Summary of changes for version 20121220:

1) ACPICA Kernel-resident Subsystem:

Implemented a new interface, AcpiWalkResourceBuffer. This interface is an 
alternate entry point for AcpiWalkResources and improves the usability of 
the resource manager by accepting as input a buffer containing the output 
of either a _CRS, _PRS, or _AEI method. The key functionality is that the 
input buffer is not deleted by this interface so that it can be used by 
the host later. See the ACPICA reference for details.

Interpreter: Add a warning if a 64-bit constant appears in a 32-bit table 
(DSDT version < 2). The constant will be truncated and this warning 
reflects that behavior.

Resource Manager: Add support for the new ACPI 5.0 wake bit in the IRQ, 
ExtendedInterrupt, and GpioInt descriptors. This change adds support to 
both get and set the new wake bit in these descriptors, separately from 
the existing share bit. Reported by Aaron Lu.

Interpreter: Fix Store() when an implicit conversion is not possible. For 
example, in the cases such as a store of a string to an existing package 
object, implement the store as a CopyObject(). This is a small departure 
from the ACPI specification which states that the control method should 
be 
aborted in this case. However, the ASLTS suite depends on this behavior.

Performance improvement for the various FUNCTION_TRACE and DEBUG_PRINT 
macros: check if debug output is currently enabled as soon as possible to 
minimize performance impact if debug is in fact not enabled.

Source code restructuring: Cleanup to improve modularity. The following 
new files have been added: dbconvert.c, evhandler.c, nsprepkg.c, 
psopinfo.c, psobject.c, rsdumpinfo.c, utstring.c, and utownerid.c. 
Associated makefiles and project files have been updated.

Changed an exception code for LoadTable operator. For the case where one 
of the input strings is too long, change the returned exception code from 
AE_BAD_PARAMETER to AE_AML_STRING_LIMIT.

Fixed a possible memory leak in dispatcher error path. On error, delete 
the mutex object created during method mutex creation. Reported by 
tim.gardner@canonical.com.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a much larger code and data size.

  Previous Release:
    Non-Debug Version:  94.3K Code, 25.3K Data, 119.6K Total
    Debug Version:     175.5K Code, 74.5K Data, 250.0K Total
  Current Release:
    Non-Debug Version:  94.5K Code, 25.5K Data, 120.0K Total
    Debug Version:     182.2K Code, 74.9K Data, 257.1K Total


2) iASL Compiler/Disassembler and Tools:

iASL: Disallow a method call as argument to the ObjectType ASL operator. 
This change tracks an errata to the ACPI 5.0 document. The AML grammar 
will not allow the interpreter to differentiate between a method and a 
method invocation when these are used as an argument to the ObjectType 
operator. The ACPI specification change is to disallow a method 
invocation 
(UserTerm) for the ObjectType operator.

Finish support for the TPM2 and CSRT tables in the headers, table 
compiler, and disassembler.

Unix user-space OSL: Fix a problem with WaitSemaphore where the timeout 
always expires immediately if the semaphore is not available. The 
original 
code was using a relative-time timeout, but sem_timedwait requires the 
use 
of an absolute time.

iASL: Added a remark if the Timer() operator is used within a 32-bit 
table. This operator returns a 64-bit time value that will be truncated 
within a 32-bit table.

iASL Source code restructuring: Cleanup to improve modularity. The 
following new files have been added: aslhex.c, aslxref.c, aslnamesp.c, 
aslmethod.c, and aslfileio.c. Associated makefiles and project files have 
been updated.


----------------------------------------
14 November 2012. Summary of changes for version 20121114:

1) ACPICA Kernel-resident Subsystem:

Implemented a performance enhancement for ACPI/AML Package objects. This 
change greatly increases the performance of Package objects within the 
interpreter. It changes the processing of reference counts for packages 
by 
optimizing for the most common case where the package sub-objects are 
either Integers, Strings, or Buffers. Increases the overall performance 
of 
the ASLTS test suite by 1.5X (Increases the Slack Mode performance by 
2X.) 
Chao Guan. ACPICA BZ 943.

Implemented and deployed common macros to extract flag bits from resource 
descriptors. Improves readability and maintainability of the code. Fixes 
a 
problem with the UART serial bus descriptor for the number of data bits 
flags (was incorrectly 2 bits, should be 3).

Enhanced the ACPI_GETx and ACPI_SETx macros. Improved the implementation 
of the macros and changed the SETx macros to the style of (destination, 
source). Also added ACPI_CASTx companion macros. Lv Zheng.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a much larger code and data size.

  Previous Release:
    Non-Debug Version:  93.9K Code, 25.2K Data, 119.1K Total
    Debug Version:     175.5K Code, 74.5K Data, 250.0K Total
  Current Release:
    Non-Debug Version:  94.3K Code, 25.3K Data, 119.6K Total
    Debug Version:     175.5K Code, 74.5K Data, 250.0K Total


2) iASL Compiler/Disassembler and Tools:

Disassembler: Added the new ACPI 5.0 interrupt sharing flags. This change 
adds the ShareAndWake and ExclusiveAndWake flags which were added to the 
Irq, Interrupt, and Gpio resource descriptors in ACPI 5.0. ACPICA BZ 986.

Disassembler: Fixed a problem with external declaration generation. Fixes 
a problem where an incorrect pathname could be generated for an external 
declaration if the original reference to the object includes leading 
carats (^). ACPICA BZ 984.

Debugger: Completed a major update for the Disassemble<method> command. 
This command was out-of-date and did not properly disassemble control 
methods that had any reasonable complexity. This fix brings the command 
up 
to the same level as the rest of the disassembler. Adds one new file, 
dmdeferred.c, which is existing code that is now common with the main 
disassembler and the debugger disassemble command. ACPICA MZ 978.

iASL: Moved the parser entry prototype to avoid a duplicate declaration. 
Newer versions of Bison emit this prototype, so moved the prototype out 
of 
the iASL header to where it is actually used in order to avoid a 
duplicate 
declaration.

iASL/Tools: Standardized use of the stream I/O functions:
  1) Ensure check for I/O error after every fopen/fread/fwrite
  2) Ensure proper order of size/count arguments for fread/fwrite
  3) Use test of (Actual != Requested) after all fwrite, and most fread
  4) Standardize I/O error messages
Improves reliability and maintainability of the code. Bob Moore, Lv 
Zheng. 
ACPICA BZ 981.

Disassembler: Prevent duplicate External() statements. During generation 
of external statements, detect similar pathnames that are actually 
duplicates such as these:
  External (\ABCD)
  External (ABCD)
Remove all leading '\' characters from pathnames during the external 
statement generation so that duplicates will be detected and tossed. 
ACPICA BZ 985.

Tools: Replace low-level I/O with stream I/O functions. Replace 
open/read/write/close with the stream I/O equivalents 
fopen/fread/fwrite/fclose for portability and performance. Lv Zheng, Bob 
Moore.

AcpiBin: Fix for the dump-to-hex function. Now correctly output the table 
name header so that AcpiXtract recognizes the output file/table.

iASL: Remove obsolete -2 option flag. Originally intended to force the 
compiler/disassembler into an ACPI 2.0 mode, this was never implemented 
and the entire concept is now obsolete.

----------------------------------------
18 October 2012. Summary of changes for version 20121018:


1) ACPICA Kernel-resident Subsystem:

Updated support for the ACPI 5.0 MPST table. Fixes some problems 
introduced by late changes to the table as it was added to the ACPI 5.0 
specification. Includes header, disassembler, and data table compiler 
support as well as a new version of the MPST template.

AcpiGetObjectInfo: Enhanced the device object support to include the ACPI 
5.0 _SUB method. Now calls _SUB in addition to the other PNP-related ID 
methods: _HID, _CID, and _UID.

Changed ACPI_DEVICE_ID to ACPI_PNP_DEVICE_ID. Also changed 
ACPI_DEVICE_ID_LIST to ACPI_PNP_DEVICE_ID_LIST. These changes prevent 
name collisions on hosts that reserve the *_DEVICE_ID (or *DeviceId) 
names for their various drivers. Affects the AcpiGetObjectInfo external 
interface, and other internal interfaces as well.

Added and deployed a new macro for ACPI_NAME management: ACPI_MOVE_NAME. 
This macro resolves to a simple 32-bit move of the 4-character ACPI_NAME 
on machines that support non-aligned transfers. Optimizes for this case 
rather than using a strncpy. With assistance from Zheng Lv.

Resource Manager: Small fix for buffer size calculation. Fixed a one byte 
error in the output buffer calculation. Feng Tang. ACPICA BZ 849.

Added a new debug print message for AML mutex objects that are force-
released. At control method termination, any currently acquired mutex 
objects are force-released. Adds a new debug-only message for each one 
that is released.

Audited/updated all ACPICA return macros and the function debug depth 
counter: 1) Ensure that all functions that use the various TRACE macros 
also use the appropriate ACPICA return macros. 2) Ensure that all normal 
return statements surround the return expression (value) with parens to 
ensure consistency across the ACPICA code base. Guan Chao, Tang Feng, 
Zheng Lv, Bob Moore. ACPICA Bugzilla 972.

Global source code changes/maintenance: All extra lines at the start and 
end of each source file have been removed for consistency. Also, within 
comments, all new sentences start with a single space instead of a double 
space, again for consistency across the code base.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a much larger code and data size.

  Previous Release:
    Non-Debug Version:  93.7K Code, 25.3K Data, 119.0K Total
    Debug Version:     175.0K Code, 74.4K Data, 249.4K Total
  Current Release:
    Non-Debug Version:  93.9K Code, 25.2K Data, 119.1K Total
    Debug Version:     175.5K Code, 74.5K Data, 250.0K Total


2) iASL Compiler/Disassembler and Tools:

AcpiExec: Improved the algorithm used for memory leak/corruption 
detection. Added some intelligence to the code that maintains the global 
list of allocated memory. The list is now ordered by allocated memory 
address, significantly improving performance. When running AcpiExec on 
the ASLTS test suite, speed improvements of 3X to 5X are seen, depending 
on the platform and/or the environment. Note, this performance 
enhancement affects the AcpiExec utility only, not the kernel-resident 
ACPICA code.

Enhanced error reporting for invalid AML opcodes and bad ACPI_NAMEs. For 
the disassembler, dump the 48 bytes surrounding the invalid opcode. Fix 
incorrect table offset reported for invalid opcodes. Report the original 
32-bit value for bad ACPI_NAMEs (as well as the repaired name.)

Disassembler: Enhanced the -vt option to emit the binary table data in 
hex format to assist with debugging.

Fixed a potential filename buffer overflow in osunixdir.c. Increased the 
size of file structure. Colin Ian King.

----------------------------------------
13 September 2012. Summary of changes for version 20120913:


1) ACPICA Kernel-resident Subsystem:

ACPI 5.0: Added two new notify types for the Hardware Error Notification 
Structure within the Hardware Error Source Table (HEST) table -- CMCI(5) 
and 
MCE(6).
 
Table Manager: Merged/removed duplicate code in the root table resize 
functions. One function is external, the other is internal. Lv Zheng, 
ACPICA 
BZ 846.

Makefiles: Completely removed the obsolete "Linux" makefiles under 
acpica/generate/linux. These makefiles are obsolete and have been 
replaced 
by 
the generic unix makefiles under acpica/generate/unix.

Makefiles: Ensure that binary files always copied properly. Minor rule 
change 
to ensure that the final binary output files are always copied up to the 
appropriate binary directory (bin32 or bin64.)

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 
debug 
version of the code includes the debug output trace mechanism and has a 
much 
larger code and data size.

  Previous Release:
    Non-Debug Version:  93.8K Code, 25.3K Data, 119.1K Total
    Debug Version:     175.7K Code, 74.8K Data, 250.5K Total
  Current Release:
    Non-Debug Version:  93.7K Code, 25.3K Data, 119.0K Total
    Debug Version:     175.0K Code, 74.4K Data, 249.4K Total


2) iASL Compiler/Disassembler and Tools:

Disassembler: Fixed a possible fault during the disassembly of resource 
descriptors when a second parse is required because of the invocation of 
external control methods within the table. With assistance from 
adq@lidskialf.net. ACPICA BZ 976.

iASL: Fixed a namepath optimization problem. An error can occur if the 
parse 
node that contains the namepath to be optimized does not have a parent 
node 
that is a named object. This change fixes the problem.

iASL: Fixed a regression where the AML file is not deleted on errors. The 
AML 
output file should be deleted if there are any errors during the 
compiler. 
The 
only exception is if the -f (force output) option is used. ACPICA BZ 974.

iASL: Added a feature to automatically increase internal line buffer 
sizes. 
Via realloc(), automatically increase the internal line buffer sizes as 
necessary to support very long source code lines. The current version of 
the 
preprocessor requires a buffer long enough to contain full source code 
lines. 
This change increases the line buffer(s) if the input lines go beyond the 
current buffer size. This eliminates errors that occurred when a source 
code 
line was longer than the buffer.

iASL: Fixed a problem with constant folding in method declarations. The 
SyncLevel term is a ByteConstExpr, and incorrect code would be generated 
if a 
Type3 opcode was used.

Debugger: Improved command help support. For incorrect argument count, 
display 
full help for the command. For help command itself, allow an argument to 
specify a command.

Test Suites: Several bug fixes for the ASLTS suite reduces the number of 
errors during execution of the suite. Guan Chao.

----------------------------------------
16 August 2012. Summary of changes for version 20120816:


1) ACPICA Kernel-resident Subsystem:

Removed all use of the deprecated _GTS and _BFS predefined methods. The 
_GTS 
(Going To Sleep) and _BFS (Back From Sleep) methods are essentially 
deprecated and will probably be removed from the ACPI specification. 
Windows 
does not invoke them, and reportedly never will. The final nail in the 
coffin 
is that the ACPI specification states that these methods must be run with 
interrupts off, which is not going to happen in a kernel interpreter. 
Note: 
Linux has removed all use of the methods also. It was discovered that 
invoking these functions caused failures on some machines, probably 
because 
they were never tested since Windows does not call them. Affects two 
external 
interfaces, AcpiEnterSleepState and AcpiLeaveSleepStatePrep. Tang Feng. 
ACPICA BZ 969.

Implemented support for complex bit-packed buffers returned from the _PLD 
(Physical Location of Device) predefined method. Adds a new external 
interface, AcpiDecodePldBuffer that parses the buffer into a more usable 
C 
structure. Note: C Bitfields cannot be used for this type of predefined 
structure since the memory layout of individual bitfields is not defined 
by 
the C language. In addition, there are endian concerns where a compiler 
will 
change the bitfield ordering based on the machine type. The new ACPICA 
interface eliminates these issues, and should be called after _PLD is 
executed. ACPICA BZ 954.

Implemented a change to allow a scope change to root (via "Scope (\)") 
during 
execution of module-level ASL code (code that is executed at table load 
time.) Lin Ming.

Added the Windows8/Server2012 string for the _OSI method. This change 
adds 
a 
new _OSI string, "Windows 2012" for both Windows 8 and Windows Server 
2012.

Added header support for the new ACPI tables DBG2 (Debug Port Table Type 
2) 
and CSRT (Core System Resource Table).

Added struct header support for the _FDE, _GRT, _GTM, and _SRT predefined 
names. This simplifies access to the buffers returned by these predefined 
names. Adds a new file, include/acbuffer.h. ACPICA BZ 956.

GPE support: Removed an extraneous parameter from the various low-level 
internal GPE functions. Tang Feng.

Removed the linux makefiles from the unix packages. The generate/linux 
makefiles are obsolete and have been removed from the unix tarball 
release 
packages. The replacement makefiles are under generate/unix, and there is 
a 
top-level makefile under the main acpica directory. ACPICA BZ 967, 912.

Updates for Unix makefiles:
1) Add -D_FORTIFY_SOURCE=2 for gcc generation. Arjan van de Ven.
2) Update linker flags (move to end of command line) for AcpiExec 
utility. 
Guan Chao.

Split ACPICA initialization functions to new file, utxfinit.c. Split from 
utxface.c to improve modularity and reduce file size.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a 
much larger code and data size.

  Previous Release:
    Non-Debug Version:  93.5K Code, 25.3K Data, 118.8K Total
    Debug Version:     173.7K Code, 74.0K Data, 247.7K Total
  Current Release:
    Non-Debug Version:  93.8K Code, 25.3K Data, 119.1K Total
    Debug Version:     175.7K Code, 74.8K Data, 250.5K Total


2) iASL Compiler/Disassembler and Tools:

iASL: Fixed a problem with constant folding for fixed-length constant 
expressions. The constant-folding code was not being invoked for constant 
expressions that allow the use of type 3/4/5 opcodes to generate 
constants 
for expressions such as ByteConstExpr, WordConstExpr, etc. This could 
result 
in the generation of invalid AML bytecode. ACPICA BZ 970.

iASL: Fixed a generation issue on newer versions of Bison. Newer versions 
apparently automatically emit some of the necessary externals. This 
change 
handles these versions in order to eliminate generation warnings.

Disassembler: Added support to decode the DBG2 and CSRT ACPI tables.

Disassembler: Add support to decode _PLD buffers. The decoded buffer 
appears 
within comments in the output file.

Debugger: Fixed a regression with the "Threads" command where 
AE_BAD_PARAMETER was always returned.

----------------------------------------
11 July 2012. Summary of changes for version 20120711:

1) ACPICA Kernel-resident Subsystem:

Fixed a possible fault in the return package object repair code. Fixes a 
problem that can occur when a lone package object is wrapped with an 
outer 
package object in order to force conformance to the ACPI specification. 
Can 
affect these predefined names: _ALR, _MLS, _PSS, _TRT, _TSS, _PRT, _HPX, 
_DLM, 
_CSD, _PSD, _TSD.

Removed code to disable/enable bus master arbitration (ARB_DIS bit in the 
PM2_CNT register) in the ACPICA sleep/wake interfaces. Management of the 
ARB_DIS bit must be implemented in the host-dependent C3 processor power 
state 
support. Note, ARB_DIS is obsolete and only applies to older chipsets, 
both 
Intel and other vendors. (for Intel: ICH4-M and earlier)

This change removes the code to disable/enable bus master arbitration 
during 
suspend/resume. Use of the ARB_DIS bit in the optional PM2_CNT register 
causes 
resume problems on some machines. The change has been in use for over 
seven 
years within Linux.

Implemented two new external interfaces to support host-directed dynamic 
ACPI 
table load and unload. They are intended to simplify the host 
implementation 
of hot-plug support:
  AcpiLoadTable: Load an SSDT from a buffer into the namespace.
  AcpiUnloadParentTable: Unload an SSDT via a named object owned by the 
table.
See the ACPICA reference for additional details. Adds one new file, 
components/tables/tbxfload.c

Implemented and deployed two new interfaces for errors and warnings that 
are 
known to be caused by BIOS/firmware issues:
  AcpiBiosError: Prints "ACPI Firmware Error" message.
  AcpiBiosWarning: Prints "ACPI Firmware Warning" message.
Deployed these new interfaces in the ACPICA Table Manager code for ACPI 
table 
and FADT errors. Additional deployment to be completed as appropriate in 
the 
future. The associated conditional macros are ACPI_BIOS_ERROR and 
ACPI_BIOS_WARNING. See the ACPICA reference for additional details. 
ACPICA 
BZ 
843.

Implicit notify support: ensure that no memory allocation occurs within a 
critical region. This fix moves a memory allocation outside of the time 
that a 
spinlock is held. Fixes issues on systems that do not allow this 
behavior. 
Jung-uk Kim.

Split exception code utilities and tables into a new file, 
utilities/utexcep.c

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 
debug 
version of the code includes the debug output trace mechanism and has a 
much 
larger code and data size.

  Previous Release:
    Non-Debug Version:  93.1K Code, 25.1K Data, 118.2K Total
    Debug Version:     172.9K Code, 73.6K Data, 246.5K Total
  Current Release:
    Non-Debug Version:  93.5K Code, 25.3K Data, 118.8K Total
    Debug Version:     173.7K Code, 74.0K Data, 247.7K Total


2) iASL Compiler/Disassembler and Tools:

iASL: Fixed a parser problem for hosts where EOF is defined as -1 instead 
of 
0. Jung-uk Kim.

Debugger: Enhanced the "tables" command to emit additional information 
about 
the current set of ACPI tables, including the owner ID and flags decode.

Debugger: Reimplemented the "unload" command to use the new 
AcpiUnloadParentTable external interface. This command was disable 
previously 
due to need for an unload interface.

AcpiHelp: Added a new option to decode ACPICA exception codes. The -e 
option 
will decode 16-bit hex status codes (ACPI_STATUS) to name strings.

----------------------------------------
20 June 2012. Summary of changes for version 20120620:


1) ACPICA Kernel-resident Subsystem:

Implemented support to expand the "implicit notify" feature to allow 
multiple 
devices to be notified by a single GPE. This feature automatically 
generates a 
runtime device notification in the absence of a BIOS-provided GPE control 
method (_Lxx/_Exx) or a host-installed handler for the GPE. Implicit 
notify is 
provided by ACPICA for Windows compatibility, and is a workaround for 
BIOS 
AML 
code errors. See the description of the AcpiSetupGpeForWake interface in 
the 
APCICA reference. Bob Moore, Rafael Wysocki. ACPICA BZ 918.

Changed some comments and internal function names to simplify and ensure 
correctness of the Linux code translation. No functional changes.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 
debug 
version of the code includes the debug output trace mechanism and has a 
much 
larger code and data size.

  Previous Release:
    Non-Debug Version:  93.0K Code, 25.1K Data, 118.1K Total
    Debug Version:     172.7K Code, 73.6K Data, 246.3K Total
  Current Release:
    Non-Debug Version:  93.1K Code, 25.1K Data, 118.2K Total
    Debug Version:     172.9K Code, 73.6K Data, 246.5K Total


2) iASL Compiler/Disassembler and Tools:

Disassembler: Added support to emit short, commented descriptions for the 
ACPI 
predefined names in order to improve the readability of the disassembled 
output. ACPICA BZ 959. Changes include:
  1) Emit descriptions for all standard predefined names (_INI, _STA, 
_PRW, 
etc.)
  2) Emit generic descriptions for the special names (_Exx, _Qxx, etc.)
  3) Emit descriptions for the resource descriptor names (_MIN, _LEN, 
etc.)

AcpiSrc: Fixed several long-standing Linux code translation issues. 
Argument 
descriptions in function headers are now translated properly to lower 
case 
and 
underscores. ACPICA BZ 961. Also fixes translation problems such as 
these: 
(old -> new)
  i_aSL -> iASL
  00-7_f -> 00-7F
  16_k -> 16K
  local_fADT -> local_FADT
  execute_oSI -> execute_OSI

iASL: Fixed a problem where null bytes were inadvertently emitted into 
some 
listing files.

iASL: Added the existing debug options to the standard help screen. There 
are 
no longer two different help screens. ACPICA BZ 957.

AcpiHelp: Fixed some typos in the various predefined name descriptions. 
Also 
expand some of the descriptions where appropriate.

iASL: Fixed the -ot option (display compile times/statistics). Was not 
working 
properly for standard output; only worked for the debug file case.

----------------------------------------
18 May 2012. Summary of changes for version 20120518:


1) ACPICA Core Subsystem:

Added a new OSL interface, AcpiOsWaitEventsComplete. This interface is 
defined 
to block until asynchronous events such as notifies and GPEs have 
completed. 
Within ACPICA, it is only called before a notify or GPE handler is 
removed/uninstalled. It also may be useful for the host OS within related 
drivers such as the Embedded Controller driver. See the ACPICA reference 
for 
additional information. ACPICA BZ 868.

ACPI Tables: Added a new error message for a possible overflow failure 
during 
the conversion of FADT 32-bit legacy register addresses to internal 
common 
64-
bit GAS structure representation. The GAS has a one-byte "bit length" 
field, 
thus limiting the register length to 255 bits. ACPICA BZ 953.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 
debug 
version of the code includes the debug output trace mechanism and has a 
much 
larger code and data size.

  Previous Release:
    Non-Debug Version:  92.9K Code, 25.0K Data, 117.9K Total
    Debug Version:     172.6K Code, 73.4K Data, 246.0K Total
  Current Release:
    Non-Debug Version:  93.0K Code, 25.1K Data, 118.1K Total
    Debug Version:     172.7K Code, 73.6K Data, 246.3K Total


2) iASL Compiler/Disassembler and Tools:

iASL: Added the ACPI 5.0 "PCC" keyword for use in the Register() ASL 
macro. 
This keyword was added late in the ACPI 5.0 release cycle and was not 
implemented until now.

Disassembler: Added support for Operation Region externals. Adds missing 
support for operation regions that are defined in another table, and 
referenced locally via a Field or BankField ASL operator. Now generates 
the 
correct External statement.

Disassembler: Several additional fixes for the External() statement 
generation 
related to some ASL operators. Also, order the External() statements 
alphabetically in the disassembler output. Fixes the External() 
generation 
for 
the Create* field, Alias, and Scope operators:
 1) Create* buffer field operators - fix type mismatch warning on 
disassembly
 2) Alias - implement missing External support
 3) Scope - fix to make sure all necessary externals are emitted.

iASL: Improved pathname support. For include files, merge the prefix 
pathname 
with the file pathname and eliminate unnecessary components. Convert 
backslashes in all pathnames to forward slashes, for readability. Include 
file 
pathname changes affect both #include and Include() type operators.

iASL/DTC/Preprocessor: Gracefully handle early EOF. Handle an EOF at the 
end 
of a valid line by inserting a newline and then returning the EOF during 
the 
next call to GetNextLine. Prevents the line from being ignored due to EOF 
condition.

iASL: Implemented some changes to enhance the IDE support (-vi option.) 
Error 
and Warning messages are now correctly recognized for both the source 
code 
browser and the global error and warning counts.

----------------------------------------
20 April 2012. Summary of changes for version 20120420:


1) ACPICA Core Subsystem:

Implemented support for multiple notify handlers. This change adds 
support 
to 
allow multiple system and device notify handlers on Device, Thermal Zone, 
and 
Processor objects. This can simplify the host OS notification 
implementation. 
Also re-worked and restructured the entire notify support code to 
simplify 
handler installation, handler removal, notify event queuing, and notify 
dispatch to handler(s). Note: there can still only be two global notify 
handlers - one for system notifies and one for device notifies. There are 
no 
changes to the existing handler install/remove interfaces. Lin Ming, Bob 
Moore, Rafael Wysocki.

Fixed a regression in the package repair code where the object reference 
count was calculated incorrectly. Regression was introduced in the commit 
"Support to add Package wrappers".

Fixed a couple possible memory leaks in the AML parser, in the error 
recovery 
path. Jesper Juhl, Lin Ming.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a 
much larger code and data size.

  Previous Release:
    Non-Debug Version:  92.9K Code, 25.0K Data, 117.9K Total
    Debug Version:     172.5K Code, 73.2K Data, 245.7K Total
  Current Release:
    Non-Debug Version:  92.9K Code, 25.0K Data, 117.9K Total
    Debug Version:     172.6K Code, 73.4K Data, 246.0K Total


2) iASL Compiler/Disassembler and Tools:

iASL: Fixed a problem with the resource descriptor support where the 
length 
of the StartDependentFn and StartDependentFnNoPrio descriptors were not 
included in cumulative descriptor offset, resulting in incorrect values 
for 
resource tags within resource descriptors appearing after a 
StartDependent* 
descriptor. Reported by Petr Vandrovec. ACPICA BZ 949.

iASL and Preprocessor: Implemented full support for the #line directive 
to 
correctly track original source file line numbers through the .i 
preprocessor 
output file - for error and warning messages.

iASL: Expand the allowable byte constants for address space IDs. 
Previously, 
the allowable range was 0x80-0xFF (user-defined spaces), now the range is 
0x0A-0xFF to allow for custom and new IDs without changing the compiler.

iASL: Add option to treat all warnings as errors (-we). ACPICA BZ 948.

iASL: Add option to completely disable the preprocessor (-Pn).

iASL: Now emit all error/warning messages to standard error (stderr) by 
default (instead of the previous stdout).

ASL Test Suite (ASLTS): Reduce iASL warnings due to use of Switch(). 
Update 
for resource descriptor offset fix above. Update/cleanup error output 
routines. Enable and send iASL errors/warnings to an error logfile 
(error.txt). Send all other iASL output to a logfile (compiler.txt). 
Fixed 
several extraneous "unrecognized operator" messages.

----------------------------------------
20 March 2012. Summary of changes for version 20120320:


1) ACPICA Core Subsystem:

Enhanced the sleep/wake interfaces to optionally execute the _GTS method 
(Going To Sleep) and the _BFS method (Back From Sleep). Windows 
apparently 
does not execute these methods, and therefore these methods are often 
untested. It has been seen on some systems where the execution of these 
methods causes errors and also prevents the machine from entering S5. It 
is 
therefore suggested that host operating systems do not execute these 
methods 
by default. In the future, perhaps these methods can be optionally 
executed 
based on the age of the system and/or what is the newest version of 
Windows 
that the BIOS asks for via _OSI. Changed interfaces: AcpiEnterSleepState 
and 
AcpileaveSleepStatePrep. See the ACPICA reference and Linux BZ 13041. Lin 
Ming.

Fixed a problem where the length of the local/common FADT was set too 
early. 
The local FADT table length cannot be set to the common length until the 
original length has been examined. There is code that checks the table 
length 
and sets various fields appropriately. This can affect older machines 
with 
early FADT versions. For example, this can cause inadvertent writes to 
the 
CST_CNT register. Julian Anastasov.

Fixed a mapping issue related to a physical table override. Use the 
deferred 
mapping mechanism for tables loaded via the physical override OSL 
interface. 
This allows for early mapping before the virtual memory manager is 
available. 
Thomas Renninger, Bob Moore.

Enhanced the automatic return-object repair code: Repair a common problem 
with 
predefined methods that are defined to return a variable-length Package 
of 
sub-objects. If there is only one sub-object, some BIOS ASL code 
mistakenly 
simply returns the single object instead of a Package with one sub-
object. 
This new support will repair this error by wrapping a Package object 
around 
the original object, creating the correct and expected Package with one 
sub-
object. Names that can be repaired in this manner include: _ALR, _CSD, 
_HPX, 
_MLS, _PLD, _PRT, _PSS, _TRT, _TSS, _BCL, _DOD, _FIX, and _Sx. ACPICA BZ 
939.

Changed the exception code returned for invalid ACPI paths passed as 
parameters to external interfaces such as AcpiEvaluateObject. Was 
AE_BAD_PARAMETER, now is the more sensible AE_BAD_PATHNAME.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 
debug 
version of the code includes the debug output trace mechanism and has a 
much 
larger code and data size.

  Previous Release:
    Non-Debug Version:  93.0K Code, 25.0K Data, 118.0K Total
    Debug Version:     172.5K Code, 73.2K Data, 245.7K Total
  Current Release:
    Non-Debug Version:  92.9K Code, 25.0K Data, 117.9K Total
    Debug Version:     172.5K Code, 73.2K Data, 245.7K Total


2) iASL Compiler/Disassembler and Tools:

iASL: Added the infrastructure and initial implementation of a integrated 
C-
like preprocessor. This will simplify BIOS development process by 
eliminating 
the need for a separate preprocessing step during builds. On Windows, it 
also 
eliminates the need to install a separate C compiler. ACPICA BZ 761. Some 
features including full #define() macro support are still under 
development. 
These preprocessor directives are supported:
    #define
    #elif
    #else
    #endif
    #error
    #if
    #ifdef
    #ifndef
    #include
    #pragma message
    #undef
    #warning
In addition, these new command line options are supported:
    -D <symbol> Define symbol for preprocessor use
    -li         Create preprocessed output file (*.i)
    -P          Preprocess only and create preprocessor output file (*.i)

Table Compiler: Fixed a problem where the equals operator within an 
expression 
did not work properly.

Updated iASL to use the current versions of Bison/Flex. Updated the 
Windows 
project file to invoke these tools from the standard location. ACPICA BZ 
904. 
Versions supported:
    Flex for Windows:  V2.5.4
    Bison for Windows: V2.4.1

----------------------------------------
15 February 2012. Summary of changes for version 20120215:


1) ACPICA Core Subsystem:

There have been some major changes to the sleep/wake support code, as 
described below (a - e).

a) The AcpiLeaveSleepState has been split into two interfaces, similar to 
AcpiEnterSleepStatePrep and AcpiEnterSleepState. The new interface is 
AcpiLeaveSleepStatePrep. This allows the host to perform actions between 
the 
time the _BFS method is called and the _WAK method is called. NOTE: all 
hosts 
must update their wake/resume code or else sleep/wake will not work 
properly. 
Rafael Wysocki.

b) In AcpiLeaveSleepState, now enable all runtime GPEs before calling the 
_WAK 
method. Some machines require that the GPEs are enabled before the _WAK 
method 
is executed. Thomas Renninger.

c) In AcpiLeaveSleepState, now always clear the WAK_STS (wake status) 
bit. 
Some BIOS code assumes that WAK_STS will be cleared on resume and use it 
to 
determine whether the system is rebooting or resuming. Matthew Garrett.

d) Move the invocations of _GTS (Going To Sleep) and _BFS (Back From 
Sleep) to 
match the ACPI specification requirement. Rafael Wysocki.

e) Implemented full support for the ACPI 5.0 SleepStatus and SleepControl 
registers within the V5 FADT. This support adds two new files: 
hardware/hwesleep.c implements the support for the new registers. Moved 
all 
sleep/wake external interfaces to hardware/hwxfsleep.c.


Added a new OSL interface for ACPI table overrides, 
AcpiOsPhysicalTableOverride. This interface allows the host to override a 
table via a physical address, instead of the logical address required by 
AcpiOsTableOverride. This simplifies the host implementation. Initial 
implementation by Thomas Renninger. The ACPICA implementation creates a 
single 
shared function for table overrides that attempts both a logical and a 
physical override.

Expanded the OSL memory read/write interfaces to 64-bit data 
(AcpiOsReadMemory, AcpiOsWriteMemory.) This enables full 64-bit memory 
transfer support for GAS register structures passed to AcpiRead and 
AcpiWrite.

Implemented the ACPI_REDUCED_HARDWARE option to allow the creation of a 
custom 
build of ACPICA that supports only the ACPI 5.0 reduced hardware (SoC) 
model. 
See the ACPICA reference for details. ACPICA BZ 942. This option removes 
about 
10% of the code and 5% of the static data, and the following hardware 
ACPI 
features become unavailable:
    PM Event and Control registers
    SCI interrupt (and handler)
    Fixed Events
    General Purpose Events (GPEs)
    Global Lock
    ACPI PM timer
    FACS table (Waking vectors and Global Lock)

Updated the unix tarball directory structure to match the ACPICA git 
source 
tree. This ensures that the generic unix makefiles work properly (in 
generate/unix).  Also updated the Linux makefiles to match. ACPICA BZ 
867.

Updated the return value of the _REV predefined method to integer value 5 
to 
reflect ACPI 5.0 support.

Moved the external ACPI PM timer interface prototypes to the public 
acpixf.h 
file where they belong.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 
debug 
version of the code includes the debug output trace mechanism and has a 
much 
larger code and data size.

2) iASL Compiler/Disassembler and Tools:

Disassembler: Fixed a problem with the new ACPI 5.0 serial resource 
descriptors (I2C, SPI, UART) where the resource produce/consumer bit was 
incorrectly displayed.

AcpiHelp: Add display of ACPI/PNP device IDs that are defined in the ACPI 
specification.

----------------------------------------
11 January 2012. Summary of changes for version 20120111:


1) ACPICA Core Subsystem:

Implemented a new mechanism to allow host device drivers to check for 
address 
range conflicts with ACPI Operation Regions. Both SystemMemory and 
SystemIO 
address spaces are supported. A new external interface, 
AcpiCheckAddressRange, 
allows drivers to check an address range against the ACPI namespace. See 
the 
ACPICA reference for additional details. Adds one new file, 
utilities/utaddress.c. Lin Ming, Bob Moore.

Fixed several issues with the ACPI 5.0 FADT support: Add the sleep 
Control 
and 
Status registers, update the ACPI 5.0 flags, and update internal data 
structures to handle an FADT larger than 256 bytes. The size of the ACPI 
5.0 
FADT is 268 bytes.

Updated all ACPICA copyrights and signons to 2012. Added the 2012 
copyright to 
all module headers and signons, including the standard Linux header. This 
affects virtually every file in the ACPICA core subsystem, iASL compiler, 
and 
all ACPICA utilities.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 
debug 
version of the code includes the debug output trace mechanism and has a 
much 
larger code and data size.

    Debug Version:     170.8K Code, 72.6K Data, 243.4K Total
  Current Release:

    Debug Version:     171.7K Code, 72.9K Data, 244.5K Total


2) iASL Compiler/Disassembler and Tools:

Disassembler: fixed a problem with the automatic resource tag generation 
support. Fixes a problem where the resource tags are inadvertently not 
constructed if the table being disassembled contains external references 
to 
control methods. Moved the actual construction of the tags to after the 
final 
namespace is constructed (after 2nd parse is invoked due to external 
control 
method references.) ACPICA BZ 941.

Table Compiler: Make all "generic" operators caseless. These are the 
operators 
like UINT8, String, etc. Making these caseless improves ease-of-use. 
ACPICA BZ 
934.

----------------------------------------
23 November 2011. Summary of changes for version 20111123:

0) ACPI 5.0 Support:

This release contains full support for the ACPI 5.0 specification, as 
summarized below.

Reduced Hardware Support:
-------------------------

This support allows for ACPI systems without the usual ACPI hardware. 
This 
support is enabled by a flag in the revision 5 FADT. If it is set, ACPICA 
will 
not attempt to initialize or use any of the usual ACPI hardware. Note, 
when 
this flag is set, all of the following ACPI hardware is assumed to be not 
present and is not initialized or accessed:

    General Purpose Events (GPEs)
    Fixed Events (PM1a/PM1b and PM Control)
    Power Management Timer and Console Buttons (power/sleep)
    Real-time Clock Alarm
    Global Lock
    System Control Interrupt (SCI)
    The FACS is assumed to be non-existent

ACPI Tables:
------------

All new tables and updates to existing tables are fully supported in the 
ACPICA headers (for use by device drivers), the disassembler, and the 
iASL 
Data Table Compiler. ACPI 5.0 defines these new tables:

    BGRT        /* Boot Graphics Resource Table */
    DRTM        /* Dynamic Root of Trust for Measurement table */
    FPDT        /* Firmware Performance Data Table */
    GTDT        /* Generic Timer Description Table */
    MPST        /* Memory Power State Table */
    PCCT        /* Platform Communications Channel Table */
    PMTT        /* Platform Memory Topology Table */
    RASF        /* RAS Feature table */

Operation Regions/SpaceIDs:
---------------------------

All new operation regions are fully supported by the iASL compiler, the 
disassembler, and the ACPICA runtime code (for dispatch to region 
handlers.) 
The new operation region Space IDs are:

    GeneralPurposeIo
    GenericSerialBus

Resource Descriptors:
---------------------

All new ASL resource descriptors are fully supported by the iASL 
compiler, 
the 
ASL/AML disassembler, and the ACPICA runtime Resource Manager code 
(including 
all new predefined resource tags). New descriptors are:

    FixedDma
    GpioIo
    GpioInt
    I2cSerialBus
    SpiSerialBus
    UartSerialBus

ASL/AML Operators, New and Modified:
------------------------------------

One new operator is added, the Connection operator, which is used to 
associate 
a GeneralPurposeIo or GenericSerialBus resource descriptor with 
individual 
field objects within an operation region. Several new protocols are 
associated 
with the AccessAs operator. All are fully supported by the iASL compiler, 
disassembler, and runtime ACPICA AML interpreter:

    Connection                      // Declare Field Connection 
attributes
    AccessAs: AttribBytes (n)           // Read/Write N-Bytes Protocol
    AccessAs: AttribRawBytes (n)        // Raw Read/Write N-Bytes 
Protocol
    AccessAs: AttribRawProcessBytes (n) // Raw Process Call Protocol
    RawDataBuffer                       // Data type for Vendor Data 
fields

Predefined ASL/AML Objects:
---------------------------

All new predefined objects/control-methods are supported by the iASL 
compiler 
and the ACPICA runtime validation/repair (arguments and return values.) 
New 
predefined names include the following:

Standard Predefined Names (Objects or Control Methods):
    _AEI, _CLS, _CPC, _CWS, _DEP,
    _DLM, _EVT, _GCP, _CRT, _GWS,
    _HRV, _PRE, _PSE, _SRT, _SUB.

Resource Tags (Names used to access individual fields within resource 
descriptors):
    _DBT, _DPL, _DRS, _END, _FLC,
    _IOR, _LIN, _MOD, _PAR, _PHA,
    _PIN, _PPI, _POL, _RXL, _SLV,
    _SPE, _STB, _TXL, _VEN.

ACPICA External Interfaces:
---------------------------

Several new interfaces have been defined for use by ACPI-related device 
drivers and other host OS services:

AcpiAcquireMutex and AcpiReleaseMutex: These interfaces allow the host OS 
to 
acquire and release AML mutexes that are defined in the DSDT/SSDT tables 
provided by the BIOS. They are intended to be used in conjunction with 
the 
ACPI 5.0 _DLM (Device Lock Method) in order to provide transaction-level 
mutual exclusion with the AML code/interpreter.

AcpiGetEventResources: Returns the (formatted) resource descriptors as 
defined 
by the ACPI 5.0 _AEI object (ACPI Event Information).  This object 
provides 
resource descriptors associated with hardware-reduced platform events, 
similar 
to the AcpiGetCurrentResources interface.

Operation Region Handlers: For General Purpose IO and Generic Serial Bus 
operation regions, information about the Connection() object and any 
optional 
length information is passed to the region handler within the Context 
parameter.

AcpiBufferToResource: This interface converts a raw AML buffer containing 
a 
resource template or resource descriptor to the ACPI_RESOURCE internal 
format 
suitable for use by device drivers. Can be used by an operation region 
handler 
to convert the Connection() buffer object into a ACPI_RESOURCE.

Miscellaneous/Tools/TestSuites: 
-------------------------------

Support for extended _HID names (Four alpha characters instead of three).
Support for ACPI 5.0 features in the AcpiExec and AcpiHelp utilities.
Support for ACPI 5.0 features in the ASLTS test suite.
Fully updated documentation (ACPICA and iASL reference documents.)

ACPI Table Definition Language:
-------------------------------

Support for this language was implemented and released as a subsystem of 
the 
iASL compiler in 2010. (See the iASL compiler User Guide.)


Non-ACPI 5.0 changes for this release:
--------------------------------------

1) ACPICA Core Subsystem:

Fix a problem with operation region declarations where a failure can 
occur 
if 
the region name and an argument that evaluates to an object (such as the 
region address) are in different namespace scopes. Lin Ming, ACPICA BZ 
937.

Do not abort an ACPI table load if an invalid space ID is found within. 
This 
will be caught later if the offending method is executed. ACPICA BZ 925.

Fixed an issue with the FFixedHW space ID where the ID was not always 
recognized properly (Both ACPICA and iASL). ACPICA BZ 926.

Fixed a problem with the 32-bit generation of the unix-specific OSL 
(osunixxf.c). Lin Ming, ACPICA BZ 936.

Several changes made to enable generation with the GCC 4.6 compiler. 
ACPICA BZ 
935.

New error messages: Unsupported I/O requests (not 8/16/32 bit), and 
Index/Bank 
field registers out-of-range.

2) iASL Compiler/Disassembler and Tools:

iASL: Implemented the __PATH__ operator, which returns the full pathname 
of 
the current source file.

AcpiHelp: Automatically display expanded keyword information for all ASL 
operators.

Debugger: Add "Template" command to disassemble/dump resource template 
buffers.

Added a new master script to generate and execute the ASLTS test suite. 
Automatically handles 32- and 64-bit generation. See tests/aslts.sh

iASL: Fix problem with listing generation during processing of the 
Switch() 
operator where AML listing was disabled until the entire Switch block was 
completed.

iASL: Improve support for semicolon statement terminators. Fix "invalid 
character" message for some cases when the semicolon is used. Semicolons 
are 
now allowed after every <Term> grammar element. ACPICA BZ 927.

iASL: Fixed some possible aliasing warnings during generation. ACPICA BZ 
923.

Disassembler: Fix problem with disassembly of the DataTableRegion 
operator 
where an inadvertent "Unhandled deferred opcode" message could be 
generated.

3) Example Code and Data Size

These are the sizes for the OS-independent acpica.lib produced by the 
Microsoft Visual C++ 9.0 32-bit compiler. The debug version of the code 
includes the debug output trace mechanism and has a much larger code and 
data 
size.

  Previous Release:
    Non-Debug Version:  90.2K Code, 23.9K Data, 114.1K Total
    Debug Version:     165.6K Code, 68.4K Data, 234.0K Total
  Current Release:
    Non-Debug Version:  92.3K Code, 24.9K Data, 117.2K Total
    Debug Version:     170.8K Code, 72.6K Data, 243.4K Total

----------------------------------------
22 September 2011. Summary of changes for version 20110922:

0) ACPI 5.0 News:

Support for ACPI 5.0 in ACPICA has been underway for several months and 
will 
be released at the same time that ACPI 5.0 is officially released.

The ACPI 5.0 specification is on track for release in the next few 
months.
 
1) ACPICA Core Subsystem:

Fixed a problem where the maximum sleep time for the Sleep() operator was 
intended to be limited to two seconds, but was inadvertently limited to 
20 
seconds instead.

Linux and Unix makefiles: Added header file dependencies to ensure 
correct 
generation of ACPICA core code and utilities. Also simplified the 
makefiles 
considerably through the use of the vpath variable to specify search 
paths. 
ACPICA BZ 924.

2) iASL Compiler/Disassembler and Tools:

iASL: Implemented support to check the access length for all fields 
created to 
access named Resource Descriptor fields. For example, if a resource field 
is 
defined to be two bits, a warning is issued if a CreateXxxxField() is 
used 
with an incorrect bit length. This is implemented for all current 
resource 
descriptor names. ACPICA BZ 930.
  
Disassembler: Fixed a byte ordering problem with the output of 24-bit and 
56-
bit integers.

iASL: Fixed a couple of issues associated with variable-length package 
objects. 1) properly handle constants like One, Ones, Zero -- do not make 
a 
VAR_PACKAGE when these are used as a package length. 2) Allow the 
VAR_PACKAGE 
opcode (in addition to PACKAGE) when validating object types for 
predefined 
names.

iASL: Emit statistics for all output files (instead of just the ASL input 
and 
AML output). Includes listings, hex files, etc.

iASL: Added -G option to the table compiler to allow the compilation of 
custom 
ACPI tables. The only part of a table that is required is the standard 
36-
byte 
ACPI header.

AcpiXtract: Ported to the standard ACPICA environment (with ACPICA 
headers), 
which also adds correct 64-bit support. Also, now all output filenames 
are 
completely lower case.

AcpiExec: Ignore any non-AML tables (tables other than DSDT or SSDT) when 
loading table files. A warning is issued for any such tables. The only 
exception is an FADT. This also fixes a possible fault when attempting to 
load 
non-AML tables. ACPICA BZ 932.

AcpiHelp: Added the AccessAs and Offset operators. Fixed a problem where 
a 
missing table terminator could cause a fault when using the -p option.

AcpiSrc: Fixed a possible divide-by-zero fault when generating file 
statistics.

3) Example Code and Data Size

These are the sizes for the OS-independent acpica.lib produced by the 
Microsoft Visual C++ 9.0 32-bit compiler. The debug version of the code 
includes the debug output trace mechanism and has a much larger code and 
data 
size.

----------------------------------------
23 June 2011. Summary of changes for version 20110623:

1) ACPI CA Core Subsystem:

Updated the predefined name repair mechanism to not attempt repair of a 
_TSS 
return object if a _PSS object is present. We can only sort the _TSS 
return 
package if there is no _PSS within the same scope. This is because if 
_PSS 
is 
present, the ACPI specification dictates that the _TSS Power Dissipation 
field 
is to be ignored, and therefore some BIOSs leave garbage values in the 
_TSS 
Power field(s). In this case, it is best to just return the _TSS package 
as-
is. Reported by, and fixed with assistance from Fenghua Yu.

Added an option to globally disable the control method return value 
validation 
and repair. This runtime option can be used to disable return value 
repair 
if 
this is causing a problem on a particular machine. Also added an option 
to 
AcpiExec (-dr) to set this disable flag.

All makefiles and project files: Major changes to improve generation of 
ACPICA 
tools. ACPICA BZ 912:
    Reduce default optimization levels to improve compatibility
    For Linux, add strict-aliasing=0 for gcc 4
    Cleanup and simplify use of command line defines
    Cleanup multithread library support
    Improve usage messages

Linux-specific header: update handling of THREAD_ID and pthread. For the 
32-
bit case, improve casting to eliminate possible warnings, especially with 
the 
acpica tools.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 
debug 
version of the code includes the debug output trace mechanism and has a 
much 
larger code and data size.

    Non-Debug Version:  90.1K Code, 23.9K Data, 114.0K Total
    Debug Version:     165.6K Code, 68.4K Data, 234.0K Total
  Current Release (VC 9.0):
    Non-Debug Version:  90.2K Code, 23.9K Data, 114.1K Total
    Debug Version:     165.6K Code, 68.4K Data, 234.0K Total

2) iASL Compiler/Disassembler and Tools:

With this release, a new utility named "acpihelp" has been added to the 
ACPICA 
package. This utility summarizes the ACPI specification chapters for the 
ASL 
and AML languages. It generates under Linux/Unix as well as Windows, and 
provides the following functionality:
    Find/display ASL operator(s) -- with description and syntax.
    Find/display ASL keyword(s) -- with exact spelling and descriptions.
    Find/display ACPI predefined name(s) -- with description, number
        of arguments, and the return value data type.
    Find/display AML opcode name(s) -- with opcode, arguments, and 
grammar.
    Decode/display AML opcode -- with opcode name, arguments, and 
grammar.

Service Layers: Make multi-thread support configurable. Conditionally 
compile 
the multi-thread support so that threading libraries will not be linked 
if 
not 
necessary. The only tool that requires multi-thread support is AcpiExec.

iASL: Update yyerrror/AslCompilerError for "const" errors. Newer versions 
of 
Bison appear to want the interface to yyerror to be a const char * (or at 
least this is a problem when generating iASL on some systems.) ACPICA BZ 
923 
Pierre Lejeune.

Tools: Fix for systems where O_BINARY is not defined. Only used for 
Windows 
versions of the tools.

----------------------------------------
27 May 2011. Summary of changes for version 20110527:

1) ACPI CA Core Subsystem:

ASL Load() operator: Reinstate most restrictions on the incoming ACPI 
table 
signature. Now, only allow SSDT, OEMx, and a null signature. History:
    1) Originally, we checked the table signature for "SSDT" or "PSDT".
       (PSDT is now obsolete.)
    2) We added support for OEMx tables, signature "OEM" plus a fourth
       "don't care" character.
    3) Valid tables were encountered with a null signature, so we just
       gave up on validating the signature, (05/2008).
    4) We encountered non-AML tables such as the MADT, which caused
       interpreter errors and kernel faults. So now, we once again allow
       only SSDT, OEMx, and now, also a null signature. (05/2011).

Added the missing _TDL predefined name to the global name list in order 
to 
enable validation. Affects both the core ACPICA code and the iASL 
compiler.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 
debug 
version of the code includes the debug output trace mechanism and has a 
much 
larger code and data size.

  Previous Release (VC 9.0):
    Non-Debug Version:  90.0K Code, 23.8K Data, 113.8K Total
    Debug Version:     164.5K Code, 68.0K Data, 232.5K Total
  Current Release (VC 9.0):
    Non-Debug Version:  90.1K Code, 23.9K Data, 114.0K Total
    Debug Version:     165.6K Code, 68.4K Data, 234.0K Total

2) iASL Compiler/Disassembler and Tools:

Debugger/AcpiExec: Implemented support for "complex" method arguments on 
the 
debugger command line. This adds support beyond simple integers -- 
including 
Strings, Buffers, and Packages. Includes support for nested packages. 
Increased the default command line buffer size to accommodate these 
arguments. 
See the ACPICA reference for details and syntax. ACPICA BZ 917.
 
Debugger/AcpiExec: Implemented support for "default" method arguments for 
the 
Execute/Debug command. Now, the debugger will always invoke a control 
method 
with the required number of arguments -- even if the command line 
specifies 
none or insufficient arguments. It uses default integer values for any 
missing 
arguments. Also fixes a bug where only six method arguments maximum were 
supported instead of the required seven.

Debugger/AcpiExec: Add a maximum buffer length parameter to AcpiOsGetLine 
and 
also return status in order to prevent buffer overruns. See the ACPICA 
reference for details and syntax. ACPICA BZ 921

iASL: Cleaned up support for Berkeley yacc. A general cleanup of code and 
makefiles to simplify support for the two different but similar parser 
generators, bison and yacc.

Updated the generic unix makefile for gcc 4. The default gcc version is 
now 
expected to be 4 or greater, since options specific to gcc 4 are used.

----------------------------------------
13 April 2011. Summary of changes for version 20110413:

1) ACPI CA Core Subsystem:

Implemented support to execute a so-called "orphan" _REG method under the 
EC 
device. This change will force the execution of a _REG method underneath 
the 
EC 
device even if there is no corresponding operation region of type 
EmbeddedControl. Fixes a problem seen on some machines and apparently is 
compatible with Windows behavior. ACPICA BZ 875.

Added more predefined methods that are eligible for automatic NULL 
package 
element removal. This change adds another group of predefined names to 
the 
list 
of names that can be repaired by having NULL package elements dynamically 
removed. This group are those methods that return a single variable-
length 
package containing simple data types such as integers, buffers, strings. 
This 
includes: _ALx, _BCL, _CID,_ DOD, _EDL, _FIX, _PCL, _PLD, _PMD, _PRx, 
_PSL, 
_Sx, 
and _TZD. ACPICA BZ 914.

Split and segregated all internal global lock functions to a new file, 
evglock.c.

Updated internal address SpaceID for DataTable regions. Moved this 
internal 
space 
id in preparation for ACPI 5.0 changes that will include some new space 
IDs. 
This 
change should not affect user/host code.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib 
produced by the Microsoft Visual C++ 9.0 32-bit compiler. The debug 
version of 
the code includes the debug output trace mechanism and has a much larger 
code 
and 
data size.

  Previous Release (VC 9.0):
    Non-Debug Version:  89.8K Code, 23.8K Data, 113.6K Total
    Debug Version:     164.2K Code, 67.9K Data, 232.1K Total
  Current Release (VC 9.0):
    Non-Debug Version:  90.0K Code, 23.8K Data, 113.8K Total
    Debug Version:     164.5K Code, 68.0K Data, 232.5K Total

2) iASL Compiler/Disassembler and Tools:

iASL/DTC: Major update for new grammar features. Allow generic data types 
in 
custom ACPI tables. Field names are now optional. Any line can be split 
to 
multiple lines using the continuation char (\). Large buffers now use 
line-
continuation character(s) and no colon on the continuation lines. See the 
grammar 
update in the iASL compiler reference. ACPI BZ 910,911. Lin Ming, Bob 
Moore.

iASL: Mark ASL "Return()" and the simple "Return" as "Null" return 
statements. 
Since the parser stuffs a "zero" as the return value for these statements 
(due 
to 
the underlying AML grammar), they were seen as "return with value" by the 
iASL 
semantic checking. They are now seen correctly as "null" return 
statements.

iASL: Check if a_REG declaration has a corresponding Operation Region. 
Adds a 
check for each _REG to ensure that there is in fact a corresponding 
operation 
region declaration in the same scope. If not, the _REG method is not very 
useful 
since it probably won't be executed. ACPICA BZ 915.

iASL/DTC: Finish support for expression evaluation. Added a new 
expression 
parser 
that implements c-style operator precedence and parenthesization. ACPICA 
bugzilla 
908.

Disassembler/DTC: Remove support for () and <> style comments in data 
tables. 
Now 
that DTC has full expression support, we don't want to have comment 
strings 
that 
start with a parentheses or a less-than symbol. Now, only the standard /* 
and 
// 
comments are supported, as well as the bracket [] comments.

AcpiXtract: Fix for RSDP and dynamic SSDT extraction. These tables have 
"unusual" 
headers in the acpidump file. Update the header validation to support 
these 
tables. Problem introduced in previous AcpiXtract version in the change 
to 
support "wrong checksum" error messages emitted by acpidump utility.

iASL: Add a * option to generate all template files (as a synonym for 
ALL) 
as 
in 
"iasl -T *" or "iasl -T ALL".

iASL/DTC: Do not abort compiler on fatal errors. We do not want to 
completely 
abort the compiler on "fatal" errors, simply should abort the current 
compile. 
This allows multiple compiles with a single (possibly wildcard) compiler 
invocation.

----------------------------------------
16 March 2011. Summary of changes for version 20110316:

1) ACPI CA Core Subsystem:

Fixed a problem caused by a _PRW method appearing at the namespace root 
scope 
during the setup of wake GPEs. A fault could occur if a _PRW directly 
under 
the 
root object was passed to the AcpiSetupGpeForWake interface. Lin Ming.

Implemented support for "spurious" Global Lock interrupts. On some 
systems, a 
global lock interrupt can occur without the pending flag being set. Upon 
a 
GL 
interrupt, we now ensure that a thread is actually waiting for the lock 
before 
signaling GL availability. Rafael Wysocki, Bob Moore.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib 
produced by the Microsoft Visual C++ 9.0 32-bit compiler. The debug 
version of 
the code includes the debug output trace mechanism and has a much larger 
code 
and 
data size.

  Previous Release (VC 9.0):
    Non-Debug Version:  89.7K Code, 23.7K Data, 113.4K Total
    Debug Version:     163.9K Code, 67.5K Data, 231.4K Total
  Current Release (VC 9.0):
    Non-Debug Version:  89.8K Code, 23.8K Data, 113.6K Total
    Debug Version:     164.2K Code, 67.9K Data, 232.1K Total

2) iASL Compiler/Disassembler and Tools:

Implemented full support for the "SLIC" ACPI table. Includes support in 
the 
header files, disassembler, table compiler, and template generator. Bob 
Moore, 
Lin Ming.

AcpiXtract: Correctly handle embedded comments and messages from 
AcpiDump. 
Apparently some or all versions of acpidump will occasionally emit a 
comment 
like 
"Wrong checksum", etc., into the dump file. This was causing problems for 
AcpiXtract. ACPICA BZ 905.

iASL: Fix the Linux makefile by removing an inadvertent double file 
inclusion. 
ACPICA BZ 913.

AcpiExec: Update installation of operation region handlers. Install one 
handler 
for a user-defined address space. This is used by the ASL test suite 
(ASLTS).

----------------------------------------
11 February 2011. Summary of changes for version 20110211:

1) ACPI CA Core Subsystem:

Added a mechanism to defer _REG methods for some early-installed 
handlers. 
Most user handlers should be installed before call to 
AcpiEnableSubsystem. 
However, Event handlers and region handlers should be installed after 
AcpiInitializeObjects. Override handlers for the "default" regions should 
be 
installed early, however. This change executes all _REG methods for the 
default regions (Memory/IO/PCI/DataTable) simultaneously to prevent any 
chicken/egg issues between them. ACPICA BZ 848.

Implemented an optimization for GPE detection. This optimization will 
simply 
ignore GPE registers that contain no enabled GPEs -- there is no need to 
read the register since this information is available internally. This 
becomes more important on machines with a large GPE space. ACPICA 
bugzilla 
884. Lin Ming. Suggestion from Joe Liu.

Removed all use of the highly unreliable FADT revision field. The 
revision 
number in the FADT has been found to be completely unreliable and cannot 
be 
trusted. Only the actual table length can be used to infer the version. 
This 
change updates the ACPICA core and the disassembler so that both no 
longer 
even look at the FADT version and instead depend solely upon the FADT 
length.

Fix an unresolved name issue for the no-debug and no-error-message source 
generation cases. The _AcpiModuleName was left undefined in these cases, 
but 
it is actually needed as a parameter to some interfaces. Define 
_AcpiModuleName as a null string in these cases. ACPICA Bugzilla 888.

Split several large files (makefiles and project files updated)
  utglobal.c   -> utdecode.c
  dbcomds.c    -> dbmethod.c dbnames.c
  dsopcode.c   -> dsargs.c dscontrol.c
  dsload.c     -> dsload2.c
  aslanalyze.c -> aslbtypes.c aslwalks.c

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has 
a much larger code and data size.

  Previous Release (VC 9.0):
    Non-Debug Version:  89.7K Code, 23.7K Data, 113.4K Total
    Debug Version:     163.9K Code, 67.5K Data, 231.4K Total
  Current Release (VC 9.0):
    Non-Debug Version:  89.7K Code, 23.7K Data, 113.4K Total
    Debug Version:     163.9K Code, 67.5K Data, 231.4K Total

2) iASL Compiler/Disassembler and Tools:

iASL: Implemented the predefined macros __LINE__, __FILE__, and __DATE__. 
These are useful C-style macros with the standard definitions. ACPICA 
bugzilla 898.

iASL/DTC: Added support for integer expressions and labels. Support for 
full 
expressions for all integer fields in all ACPI tables. Support for labels 
in 
"generic" portions of tables such as UEFI. See the iASL reference manual.

Debugger: Added a command to display the status of global handlers. The 
"handlers" command will display op region, fixed event, and miscellaneous 
global handlers. installation status -- and for op regions, whether 
default 
or user-installed handler will be used.

iASL: Warn if reserved method incorrectly returns a value. Many 
predefined 
names are defined such that they do not return a value. If implemented as 
a 
method, issue a warning if such a name explicitly returns a value. ACPICA 
Bugzilla 855.

iASL: Added detection of GPE method name conflicts. Detects a conflict 
where 
there are two GPE methods of the form _Lxy and _Exy in the same scope. 
(For 
example, _L1D and _E1D in the same scope.) ACPICA bugzilla 848.

iASL/DTC: Fixed a couple input scanner issues with comments and line 
numbers. Comment remover could get confused and miss a comment ending. 
Fixed 
a problem with line counter maintenance.

iASL/DTC: Reduced the severity of some errors from fatal to error. There 
is 
no need to abort on simple errors within a field definition.

Debugger: Simplified the output of the help command. All help output now 
in 
a single screen, instead of help subcommands. ACPICA Bugzilla 897.

----------------------------------------
12 January 2011. Summary of changes for version 20110112:

1) ACPI CA Core Subsystem:

Fixed a race condition between method execution and namespace walks that 
can 
possibly cause a fault. The problem was apparently introduced in version 
20100528 as a result of a performance optimization that reduces the 
number 
of 
namespace walks upon method exit by using the delete_namespace_subtree 
function instead of the delete_namespace_by_owner function used 
previously. 
Bug is a missing namespace lock in the delete_namespace_subtree function. 
dana.myers@oracle.com

Fixed several issues and a possible fault with the automatic "serialized" 
method support. History: This support changes a method to "serialized" on 
the 
fly if the method generates an AE_ALREADY_EXISTS error, indicating the 
possibility that it cannot handle reentrancy. This fix repairs a couple 
of 
issues seen in the field, especially on machines with many cores:

    1) Delete method children only upon the exit of the last thread,
       so as to not delete objects out from under other running threads
      (and possibly causing a fault.)
    2) Set the "serialized" bit for the method only upon the exit of the
       Last thread, so as to not cause deadlock when running threads
       attempt to exit.
    3) Cleanup the use of the AML "MethodFlags" and internal method flags
       so that there is no longer any confusion between the two.

    Lin Ming, Bob Moore. Reported by dana.myers@oracle.com.

Debugger: Now lock the namespace for duration of a namespace dump. 
Prevents 
issues if the namespace is changing dynamically underneath the debugger. 
Especially affects temporary namespace nodes, since the debugger displays 
these also.

Updated the ordering of include files. The ACPICA headers should appear 
before any compiler-specific headers (stdio.h, etc.) so that acenv.h can 
set 
any necessary compiler-specific defines, etc. Affects the ACPI-related 
tools 
and utilities.

Updated all ACPICA copyrights and signons to 2011. Added the 2011 
copyright 
to all module headers and signons, including the Linux header. This 
affects 
virtually every file in the ACPICA core subsystem, iASL compiler, and all 
utilities.

Added project files for MS Visual Studio 2008 (VC++ 9.0). The original 
project files for VC++ 6.0 are now obsolete. New project files can be 
found 
under acpica/generate/msvc9. See acpica/generate/msvc9/readme.txt for 
details.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a 
much larger code and data size.

  Previous Release (VC 6.0):
    Non-Debug Version:  89.8K Code, 18.9K Data, 108.7K Total
    Debug Version:     166.6K Code, 52.1K Data, 218.7K Total
  Current Release (VC 9.0):
    Non-Debug Version:  89.7K Code, 23.7K Data, 113.4K Total
    Debug Version:     163.9K Code, 67.5K Data, 231.4K Total

2) iASL Compiler/Disassembler and Tools:

iASL: Added generic data types to the Data Table compiler. Add "generic" 
data 
types such as UINT32, String, Unicode, etc., to simplify the generation 
of 
platform-defined tables such as UEFI. Lin Ming.

iASL: Added listing support for the Data Table Compiler. Adds listing 
support 
(-l) to display actual binary output for each line of input code.

----------------------------------------
09 December 2010. Summary of changes for version 20101209:

1) ACPI CA Core Subsystem:

Completed the major overhaul of the GPE support code that was begun in 
July 
2010. Major features include: removal of _PRW execution in ACPICA (host 
executes _PRWs anyway), cleanup of "wake" GPE interfaces and processing, 
changes to existing interfaces, simplification of GPE handler operation, 
and 
a handful of new interfaces:

    AcpiUpdateAllGpes
    AcpiFinishGpe
    AcpiSetupGpeForWake
    AcpiSetGpeWakeMask
    One new file, evxfgpe.c to consolidate all external GPE interfaces.

See the ACPICA Programmer Reference for full details and programming 
information. See the new section 4.4 "General Purpose Event (GPE) 
Support" 
for a full overview, and section 8.7 "ACPI General Purpose Event 
Management" 
for programming details. ACPICA BZ 858,870,877. Matthew Garrett, Lin 
Ming, 
Bob Moore, Rafael Wysocki.

Implemented a new GPE feature for Windows compatibility, the "Implicit 
Wake 
GPE Notify". This feature will automatically issue a Notify(2) on a 
device 
when a Wake GPE is received if there is no corresponding GPE method or 
handler. ACPICA BZ 870.

Fixed a problem with the Scope() operator during table parse and load 
phase. 
During load phase (table load or method execution), the scope operator 
should 
not enter the target into the namespace. Instead, it should open a new 
scope 
at the target location. Linux BZ 19462, ACPICA BZ 882.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a 
much larger code and data size.

  Previous Release:
    Non-Debug Version:  89.8K Code, 18.9K Data, 108.7K Total
    Debug Version:     166.6K Code, 52.1K Data, 218.7K Total
  Current Release:
    Non-Debug Version:  89.9K Code, 19.0K Data, 108.9K Total
    Debug Version:     166.3K Code, 52.1K Data, 218.4K Total

2) iASL Compiler/Disassembler and Tools:

iASL: Relax the alphanumeric restriction on _CID strings. These strings 
are 
"bus-specific" per the ACPI specification, and therefore any characters 
are 
acceptable. The only checks that can be performed are for a null string 
and 
perhaps for a leading asterisk. ACPICA BZ 886.

iASL: Fixed a problem where a syntax error that caused a premature EOF 
condition on the source file emitted a very confusing error message. The 
premature EOF is now detected correctly. ACPICA BZ 891.

Disassembler: Decode the AccessSize within a Generic Address Structure 
(byte 
access, word access, etc.) Note, this field does not allow arbitrary bit 
access, the size is encoded as 1=byte, 2=word, 3=dword, and 4=qword.

New: AcpiNames utility - Example namespace dump utility. Shows an example 
of 
ACPICA configuration for a minimal namespace dump utility. Uses table and 
namespace managers, but no AML interpreter. Does not add any 
functionality 
over AcpiExec, it is a subset of AcpiExec. The purpose is to show how to 
partition and configure ACPICA. ACPICA BZ 883.

AML Debugger: Increased the debugger buffer size for method return 
objects. 
Was 4K, increased to 16K. Also enhanced error messages for debugger 
method 
execution, including the buffer overflow case.

----------------------------------------
13 October 2010. Summary of changes for version 20101013:

1) ACPI CA Core Subsystem:

Added support to clear the PCIEXP_WAKE event. When clearing ACPI events, 
now 
clear the PCIEXP_WAKE_STS bit in the ACPI PM1 Status Register, via 
HwClearAcpiStatus. Original change from Colin King. ACPICA BZ 880.

Changed the type of the predefined namespace object _TZ from ThermalZone 
to 
Device. This was found to be confusing to the host software that 
processes 
the various thermal zones, since _TZ is not really a ThermalZone. 
However, 
a 
Notify() can still be performed on it. ACPICA BZ 876. Suggestion from Rui 
Zhang.

Added Windows Vista SP2 to the list of supported _OSI strings. The actual 
string is "Windows 2006 SP2".

Eliminated duplicate code in AcpiUtExecute* functions. Now that the 
nsrepair 
code automatically repairs _HID-related strings, this type of code is no 
longer needed in Execute_HID, Execute_CID, and Execute_UID. ACPICA BZ 
878.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a 
much larger code and data size.

  Previous Release:
    Non-Debug Version:  89.9K Code, 19.0K Data, 108.9K Total
    Debug Version:     166.3K Code, 52.1K Data, 218.4K Total
  Current Release:
    Non-Debug Version:  89.9K Code, 19.0K Data, 108.9K Total
    Debug Version:     166.3K Code, 52.1K Data, 218.4K Total

2) iASL Compiler/Disassembler and Tools:

iASL: Implemented additional compile-time validation for _HID strings. 
The 
non-hex prefix (such as "PNP" or "ACPI") must be uppercase, and the 
length 
of 
the string must be exactly seven or eight characters. For both _HID and 
_CID 
strings, all characters must be alphanumeric. ACPICA BZ 874.

iASL: Allow certain "null" resource descriptors. Some BIOS code creates 
descriptors that are mostly or all zeros, with the expectation that they 
will 
be filled in at runtime. iASL now allows this as long as there is a 
"resource 
tag" (name) associated with the descriptor, which gives the ASL a handle 
needed to modify the descriptor. ACPICA BZ 873.

Added single-thread support to the generic Unix application OSL. 
Primarily 
for iASL support, this change removes the use of semaphores in the 
single-
threaded ACPICA tools/applications - increasing performance. The 
_MULTI_THREADED option was replaced by the (reverse) ACPI_SINGLE_THREADED 
option. ACPICA BZ 879.

AcpiExec: several fixes for the 64-bit version. Adds XSDT support and 
support 
for 64-bit DSDT/FACS addresses in the FADT. Lin Ming.

iASL: Moved all compiler messages to a new file, aslmessages.h.

----------------------------------------
15 September 2010. Summary of changes for version 20100915:

1) ACPI CA Core Subsystem:

Removed the AcpiOsDerivePciId OSL interface. The various host 
implementations 
of this function were not OS-dependent and are now obsolete and can be 
removed from all host OSLs. This function has been replaced by 
AcpiHwDerivePciId, which is now part of the ACPICA core code. 
AcpiHwDerivePciId has been implemented without recursion. Adds one new 
module, hwpci.c. ACPICA BZ 857.

Implemented a dynamic repair for _HID and _CID strings. The following 
problems are now repaired at runtime: 1) Remove a leading asterisk in the 
string, and 2) the entire string is uppercased. Both repairs are in 
accordance with the ACPI specification and will simplify host driver 
code. 
ACPICA BZ 871.

The ACPI_THREAD_ID type is no longer configurable, internally it is now 
always UINT64. This simplifies the ACPICA code, especially any printf 
output. 
UINT64 is the only common data type for all thread_id types across all 
operating systems. It is now up to the host OSL to cast the native 
thread_id 
type to UINT64 before returning the value to ACPICA (via 
AcpiOsGetThreadId). 
Lin Ming, Bob Moore.

Added the ACPI_INLINE type to enhance the ACPICA configuration. The 
"inline" 
keyword is not standard across compilers, and this type allows inline to 
be 
configured on a per-compiler basis. Lin Ming.

Made the system global AcpiGbl_SystemAwakeAndRunning publically 
available. 
Added an extern for this boolean in acpixf.h. Some hosts utilize this 
value 
during suspend/restore operations. ACPICA BZ 869.

All code that implements error/warning messages with the "ACPI:" prefix 
has 
been moved to a new module, utxferror.c.

The UINT64_OVERLAY was moved to utmath.c, which is the only module where 
it 
is used. ACPICA BZ 829. Lin Ming, Bob Moore.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a 
much larger code and data size.

  Previous Release:
    Non-Debug Version:  89.1K Code, 19.0K Data, 108.1K Total
    Debug Version:     165.1K Code, 51.9K Data, 217.0K Total
  Current Release:
    Non-Debug Version:  89.9K Code, 19.0K Data, 108.9K Total
    Debug Version:     166.3K Code, 52.1K Data, 218.4K Total

2) iASL Compiler/Disassembler and Tools:

iASL/Disassembler: Write ACPI errors to stderr instead of the output 
file. 
This keeps the output files free of random error messages that may 
originate 
from within the namespace/interpreter code. Used this opportunity to 
merge 
all ACPI:-style messages into a single new module, utxferror.c. ACPICA BZ 
866. Lin Ming, Bob Moore.

Tools: update some printfs for ansi warnings on size_t. Handle width 
change 
of size_t on 32-bit versus 64-bit generations. Lin Ming.

----------------------------------------
06 August 2010. Summary of changes for version 20100806:

1) ACPI CA Core Subsystem:

Designed and implemented a new host interface to the _OSI support code. 
This 
will allow the host to dynamically add or remove multiple _OSI strings, 
as 
well as install an optional handler that is called for each _OSI 
invocation. 
Also added a new AML debugger command, 'osi' to display and modify the 
global 
_OSI string table, and test support in the AcpiExec utility. See the 
ACPICA 
reference manual for full details. Lin Ming, Bob Moore. ACPICA BZ 836.
New Functions:
    AcpiInstallInterface - Add an _OSI string.
    AcpiRemoveInterface - Delete an _OSI string.
    AcpiInstallInterfaceHandler - Install optional _OSI handler.
Obsolete Functions:
    AcpiOsValidateInterface - no longer used.
New Files:
    source/components/utilities/utosi.c

Re-introduced the support to enable multi-byte transfers for Embedded 
Controller (EC) operation regions. A reported problem was found to be a 
bug 
in the host OS, not in the multi-byte support. Previously, the maximum 
data 
size passed to the EC operation region handler was a single byte. There 
are 
often EC Fields larger than one byte that need to be transferred, and it 
is 
useful for the EC driver to lock these as a single transaction. This 
change 
enables single transfers larger than 8 bits. This effectively changes the 
access to the EC space from ByteAcc to AnyAcc, and will probably require 
changes to the host OS Embedded Controller driver to enable 16/32/64/256-
bit 
transfers in addition to 8-bit transfers. Alexey Starikovskiy, Lin Ming.

Fixed a problem with the prototype for AcpiOsReadPciConfiguration. The 
prototype in acpiosxf.h had the output value pointer as a (void *).
It should be a (UINT64 *). This may affect some host OSL code.

Fixed a couple problems with the recently modified Linux makefiles for 
iASL 
and AcpiExec. These new makefiles place the generated object files in the 
local directory so that there can be no collisions between the files that 
are 
shared between them that are compiled with different options.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a 
much larger code and data size.

  Previous Release:
    Non-Debug Version:  88.3K Code, 18.8K Data, 107.1K Total
    Debug Version:     164.0K Code, 51.5K Data, 215.5K Total
  Current Release:
    Non-Debug Version:  89.1K Code, 19.0K Data, 108.1K Total
    Debug Version:     165.1K Code, 51.9K Data, 217.0K Total

2) iASL Compiler/Disassembler and Tools:

iASL/Disassembler: Added a new option (-da, "disassemble all") to load 
the 
namespace from and disassemble an entire group of AML files. Useful for 
loading all of the AML tables for a given machine (DSDT, SSDT1...SSDTn) 
and 
disassembling with one simple command. ACPICA BZ 865. Lin Ming.

iASL: Allow multiple invocations of -e option. This change allows 
multiple 
uses of -e on the command line: "-e ssdt1.dat -e ssdt2.dat". ACPICA BZ 
834. 
Lin Ming.

----------------------------------------
02 July 2010. Summary of changes for version 20100702:

1) ACPI CA Core Subsystem:

Implemented several updates to the recently added GPE reference count 
support. The model for "wake" GPEs is changing to give the host OS 
complete 
control of these GPEs. Eventually, the ACPICA core will not execute any 
_PRW 
methods, since the host already must execute them. Also, additional 
changes 
were made to help ensure that the reference counts are kept in proper 
synchronization with reality. Rafael J. Wysocki.

1) Ensure that GPEs are not enabled twice during initialization.
2) Ensure that GPE enable masks stay in sync with the reference count.
3) Do not inadvertently enable GPEs when writing GPE registers.
4) Remove the internal wake reference counter and add new AcpiGpeWakeup 
interface. This interface will set or clear individual GPEs for wakeup.
5) Remove GpeType argument from AcpiEnable and AcpiDisable. These 
interfaces 
are now used for "runtime" GPEs only.

Changed the behavior of the GPE install/remove handler interfaces. The 
GPE 
is 
no longer disabled during this process, as it was found to cause problems 
on 
some machines. Rafael J. Wysocki.

Reverted a change introduced in version 20100528 to enable Embedded 
Controller multi-byte transfers. This change was found to cause problems 
with 
Index Fields and possibly Bank Fields. It will be reintroduced when these 
problems have been resolved.

Fixed a problem with references to Alias objects within Package Objects. 
A 
reference to an Alias within the definition of a Package was not always 
resolved properly. Aliases to objects like Processors, Thermal zones, 
etc. 
were resolved to the actual object instead of a reference to the object 
as 
it 
should be. Package objects are only allowed to contain integer, string, 
buffer, package, and reference objects. Redhat bugzilla 608648.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a 
much larger code and data size.

  Previous Release:
    Non-Debug Version:  88.3K Code, 18.8K Data, 107.1K Total
    Debug Version:     164.1K Code, 51.5K Data, 215.6K Total
  Current Release:
    Non-Debug Version:  88.3K Code, 18.8K Data, 107.1K Total
    Debug Version:     164.0K Code, 51.5K Data, 215.5K Total

2) iASL Compiler/Disassembler and Tools:

iASL: Implemented a new compiler subsystem to allow definition and 
compilation of the non-AML ACPI tables such as FADT, MADT, SRAT, etc. 
These 
are called "ACPI Data Tables", and the new compiler is the "Data Table 
Compiler". This compiler is intended to simplify the existing error-prone 
process of creating these tables for the BIOS, as well as allowing the 
disassembly, modification, recompilation, and override of existing ACPI 
data 
tables. See the iASL User Guide for detailed information.

iASL: Implemented a new Template Generator option in support of the new 
Data 
Table Compiler. This option will create examples of all known ACPI tables 
that can be used as the basis for table development. See the iASL 
documentation and the -T option.

Disassembler and headers: Added support for the WDDT ACPI table (Watchdog 
Descriptor Table).

Updated the Linux makefiles for iASL and AcpiExec to place the generated 
object files in the local directory so that there can be no collisions 
between the shared files between them that are generated with different 
options.

Added support for Mac OS X in the Unix OSL used for iASL and AcpiExec. 
Use 
the #define __APPLE__ to enable this support.

----------------------------------------
28 May 2010. Summary of changes for version 20100528:

Note: The ACPI 4.0a specification was released on April 5, 2010 and is 
available at www.acpi.info. This is primarily an errata release.

1) ACPI CA Core Subsystem:

Undefined ACPI tables: We are looking for the definitions for the 
following 
ACPI tables that have been seen in the field: ATKG, IEIT, GSCI.

Implemented support to enable multi-byte transfers for Embedded 
Controller 
(EC) operation regions. Previously, the maximum data size passed to the 
EC 
operation region handler was a single byte. There are often EC Fields 
larger 
than one byte that need to be transferred, and it is useful for the EC 
driver 
to lock these as a single transaction. This change enables single 
transfers 
larger than 8 bits. This effectively changes the access to the EC space 
from 
ByteAcc to AnyAcc, and will probably require changes to the host OS 
Embedded 
Controller driver to enable 16/32/64/256-bit transfers in addition to 8-
bit 
transfers. Alexey Starikovskiy, Lin Ming

Implemented a performance enhancement for namespace search and access. 
This 
change enhances the performance of namespace searches and walks by adding 
a 
backpointer to the parent in each namespace node. On large namespaces, 
this 
change can improve overall ACPI performance by up to 9X. Adding a pointer 
to 
each namespace node increases the overall size of the internal namespace 
by 
about 5%, since each namespace entry usually consists of both a namespace 
node and an ACPI operand object. However, this is the first growth of the 
namespace in ten years. ACPICA bugzilla 817. Alexey Starikovskiy.

Implemented a performance optimization that reduces the number of 
namespace 
walks. On control method exit, only walk the namespace if the method is 
known 
to have created namespace objects outside of its local scope. Previously, 
the 
entire namespace was traversed on each control method exit. This change 
can 
improve overall ACPI performance by up to 3X. Alexey Starikovskiy, Bob 
Moore.

Added support to truncate I/O addresses to 16 bits for Windows 
compatibility. 
Some ASL code has been seen in the field that inadvertently has bits set 
above bit 15. This feature is optional and is enabled if the BIOS 
requests 
any Windows OSI strings. It can also be enabled by the host OS. Matthew 
Garrett, Bob Moore.

Added support to limit the maximum time for the ASL Sleep() operator. To 
prevent accidental deep sleeps, limit the maximum time that Sleep() will 
actually sleep. Configurable, the default maximum is two seconds. ACPICA 
bugzilla 854.

Added run-time validation support for the _WDG and_WED Microsoft 
predefined 
methods. These objects are defined by "Windows Instrumentation", and are 
not 
part of the ACPI spec. ACPICA BZ 860.

Expanded all statistic counters used during namespace and device 
initialization from 16 to 32 bits in order to support very large 
namespaces.

Replaced all instances of %d in printf format specifiers with %u since 
nearly 
all integers in ACPICA are unsigned.

Fixed the exception namestring for AE_WAKE_ONLY_GPE. Was incorrectly 
returned 
as AE_NO_HANDLER.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a 
much larger code and data size.

2) iASL Compiler/Disassembler and Tools:

iASL: Added compiler support for the _WDG and_WED Microsoft predefined 
methods. These objects are defined by "Windows Instrumentation", and are 
not 
part of the ACPI spec. ACPICA BZ 860.

AcpiExec: added option to disable the memory tracking mechanism. The -dt 
option will disable the tracking mechanism, which improves performance 
considerably.

AcpiExec: Restructured the command line options into -d (disable) and -e 
(enable) options.

----------------------------------------
28 April 2010. Summary of changes for version 20100428:

1) ACPI CA Core Subsystem:

Implemented GPE support for dynamically loaded ACPI tables. For all GPEs, 
including FADT-based and GPE Block Devices, execute any _PRW methods in 
the 
new table, and process any _Lxx/_Exx GPE methods in the new table. Any 
runtime GPE that is referenced by an _Lxx/_Exx method in the new table is 
immediately enabled. Handles the FADT-defined GPEs as well as GPE Block 
Devices. Provides compatibility with other ACPI implementations. Two new 
files added, evgpeinit.c and evgpeutil.c. ACPICA BZ 833. Lin Ming, Bob 
Moore.

Fixed a regression introduced in version 20100331 within the table 
manager 
where initial table loading could fail. This was introduced in the fix 
for 
AcpiReallocateRootTable. Also, renamed some of fields in the table 
manager 
data structures to clarify their meaning and use.

Fixed a possible allocation overrun during internal object copy in 
AcpiUtCopySimpleObject. The original code did not correctly handle the 
case 
where the object to be copied was a namespace node. Lin Ming. ACPICA BZ 
847.

Updated the allocation dump routine, AcpiUtDumpAllocation and fixed a 
possible access beyond end-of-allocation. Also, now fully validate 
descriptor 
(size and type) before output. Lin Ming, Bob Moore. ACPICA BZ 847

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a 
much larger code and data size.

  Previous Release:
    Non-Debug Version:  87.9K Code, 18.6K Data, 106.5K Total
    Debug Version:     163.5K Code, 51.3K Data, 214.8K Total
  Current Release:
    Non-Debug Version:  88.4K Code, 18.8K Data, 107.2K Total
    Debug Version:     164.2K Code, 51.5K Data, 215.7K Total

2) iASL Compiler/Disassembler and Tools:

iASL: Implemented Min/Max/Len/Gran validation for address resource 
descriptors. This change implements validation for the address fields 
that 
are common to all address-type resource descriptors. These checks are 
implemented: Checks for valid Min/Max, length within the Min/Max window, 
valid granularity, Min/Max a multiple of granularity, and _MIF/_MAF as 
per 
table 6-40 in the ACPI 4.0a specification. Also split the large 
aslrestype1.c 
and aslrestype2.c files into five new files. ACPICA BZ 840.

iASL: Added support for the _Wxx predefined names. This support was 
missing 
and these names were not recognized by the compiler as valid predefined 
names. ACPICA BZ 851.

iASL: Added an error for all predefined names that are defined to return 
no 
value and thus must be implemented as Control Methods. These include all 
of 
the _Lxx, _Exx, _Wxx, and _Qxx names, as well as some other miscellaneous 
names such as _DIS, _INI, _IRC, _OFF, _ON, and _PSx. ACPICA BZ 850, 856.

iASL: Implemented the -ts option to emit hex AML data in ASL format, as 
an 
ASL Buffer. Allows ACPI tables to be easily included within ASL files, to 
be 
dynamically loaded via the Load() operator. Also cleaned up output for 
the 
-
ta and -tc options. ACPICA BZ 853.

Tests: Added a new file with examples of extended iASL error checking. 
Demonstrates the advanced error checking ability of the iASL compiler. 
Available at tests/misc/badcode.asl.

----------------------------------------
31 March 2010. Summary of changes for version 20100331:

1) ACPI CA Core Subsystem:

Completed a major update for the GPE support in order to improve support 
for 
shared GPEs and to simplify both host OS and ACPICA code. Added a 
reference 
count mechanism to support shared GPEs that require multiple device 
drivers. 
Several external interfaces have changed. One external interface has been 
removed. One new external interface was added. Most of the GPE external 
interfaces now use the GPE spinlock instead of the events mutex (and the 
Flags parameter for many GPE interfaces has been removed.) See the 
updated 
ACPICA Programmer Reference for details. Matthew Garrett, Bob Moore, 
Rafael 
Wysocki. ACPICA BZ 831.

Changed:
    AcpiEnableGpe, AcpiDisableGpe, AcpiClearGpe, AcpiGetGpeStatus
Removed:
    AcpiSetGpeType
New:
    AcpiSetGpe

Implemented write support for DataTable operation regions. These regions 
are 
defined via the DataTableRegion() operator. Previously, only read support 
was 
implemented. The ACPI specification allows DataTableRegions to be 
read/write, 
however.

Implemented a new subsystem option to force a copy of the DSDT to local 
memory. Optionally copy the entire DSDT to local memory (instead of 
simply 
mapping it.) There are some (albeit very rare) BIOSs that corrupt or 
replace 
the original DSDT, creating the need for this option. Default is FALSE, 
do 
not copy the DSDT.

Implemented detection of a corrupted or replaced DSDT. This change adds 
support to detect a DSDT that has been corrupted and/or replaced from 
outside 
the OS (by firmware). This is typically catastrophic for the system, but 
has 
been seen on some machines. Once this problem has been detected, the DSDT 
copy option can be enabled via system configuration. Lin Ming, Bob Moore.

Fixed two problems with AcpiReallocateRootTable during the root table 
copy. 
When copying the root table to the new allocation, the length used was 
incorrect. The new size was used instead of the current table size, 
meaning 
too much data was copied. Also, the count of available slots for ACPI 
tables 
was not set correctly. Alexey Starikovskiy, Bob Moore.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a 
much larger code and data size.

  Previous Release:
    Non-Debug Version:  87.5K Code, 18.4K Data, 105.9K Total
    Debug Version:     163.4K Code, 51.1K Data, 214.5K Total
  Current Release:
    Non-Debug Version:  87.9K Code, 18.6K Data, 106.5K Total
    Debug Version:     163.5K Code, 51.3K Data, 214.8K Total

2) iASL Compiler/Disassembler and Tools:

iASL: Implement limited typechecking for values returned from predefined 
control methods. The type of any returned static (unnamed) object is now 
validated. For example, Return(1). ACPICA BZ 786.

iASL: Fixed a predefined name object verification regression. Fixes a 
problem 
introduced in version 20100304. An error is incorrectly generated if a 
predefined name is declared as a static named object with a value defined 
using the keywords "Zero", "One", or "Ones". Lin Ming.

iASL: Added Windows 7 support for the -g option (get local ACPI tables) 
by 
reducing the requested registry access rights. ACPICA BZ 842.

Disassembler: fixed a possible fault when generating External() 
statements. 
Introduced in commit ae7d6fd: Properly handle externals with parent-
prefix 
(carat). Fixes a string length allocation calculation. Lin Ming.

----------------------------------------
04 March 2010. Summary of changes for version 20100304:

1) ACPI CA Core Subsystem:

Fixed a possible problem with the AML Mutex handling function 
AcpiExReleaseMutex where the function could fault under the very rare 
condition when the interpreter has blocked, the interpreter lock is 
released, 
the interpreter is then reentered via the same thread, and attempts to 
acquire an AML mutex that was previously acquired. FreeBSD report 140979. 
Lin 
Ming.

Implemented additional configuration support for the AML "Debug Object". 
Output from the debug object can now be enabled via a global variable, 
AcpiGbl_EnableAmlDebugObject. This will assist with remote machine 
debugging. 
This debug output is now available in the release version of ACPICA 
instead 
of just the debug version. Also, the entire debug output module can now 
be 
configured out of the ACPICA build if desired. One new file added, 
executer/exdebug.c. Lin Ming, Bob Moore.

Added header support for the ACPI MCHI table (Management Controller Host 
Interface Table). This table was added in ACPI 4.0, but the defining 
document 
has only recently become available.

Standardized output of integer values for ACPICA warnings/errors. Always 
use 
0x prefix for hex output, always use %u for unsigned integer decimal 
output. 
Affects ACPI_INFO, ACPI_ERROR, ACPI_EXCEPTION, and ACPI_WARNING (about 
400 
invocations.) These invocations were converted from the original 
ACPI_DEBUG_PRINT invocations and were not consistent. ACPICA BZ 835.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a 
much larger code and data size.

  Previous Release:
    Non-Debug Version:  87.1K Code, 18.0K Data, 105.1K Total
    Debug Version:     163.5K Code, 50.9K Data, 214.4K Total
  Current Release:
    Non-Debug Version:  87.5K Code, 18.4K Data, 105.9K Total
    Debug Version:     163.4K Code, 51.1K Data, 214.5K Total

2) iASL Compiler/Disassembler and Tools:

iASL: Implemented typechecking support for static (non-control method) 
predefined named objects that are declared with the Name() operator. For 
example, the type of this object is now validated to be of type Integer: 
Name(_BBN, 1). This change migrates the compiler to using the core 
predefined 
name table instead of maintaining a local version. Added a new file, 
aslpredef.c. ACPICA BZ 832.

Disassembler: Added support for the ACPI 4.0 MCHI table.

----------------------------------------
21 January 2010. Summary of changes for version 20100121:

1) ACPI CA Core Subsystem:

Added the 2010 copyright to all module headers and signons. This affects 
virtually every file in the ACPICA core subsystem, the iASL compiler, the 
tools/utilities, and the test suites.

Implemented a change to the AcpiGetDevices interface to eliminate 
unnecessary 
invocations of the _STA method. In the case where a specific _HID is 
requested, do not run _STA until a _HID match is found. This eliminates 
potentially dozens of _STA calls during a search for a particular 
device/HID, 
which in turn can improve boot times. ACPICA BZ 828. Lin Ming.

Implemented an additional repair for predefined method return values. 
Attempt 
to repair unexpected NULL elements within returned Package objects. 
Create 
an 
Integer of value zero, a NULL String, or a zero-length Buffer as 
appropriate. 
ACPICA BZ 818. Lin Ming, Bob Moore.

Removed the obsolete ACPI_INTEGER data type. This type was introduced as 
the 
code was migrated from ACPI 1.0 (with 32-bit AML integers) to ACPI 2.0 
(with 
64-bit AML integers). It is now obsolete and this change removes it from 
the 
ACPICA code base, replaced by UINT64. The original typedef has been 
retained 
for now for compatibility with existing device driver code. ACPICA BZ 
824.

Removed the unused UINT32_STRUCT type, and the obsolete Integer64 field 
in 
the parse tree object.

Added additional warning options for the gcc-4 generation. Updated the 
source 
accordingly. This includes some code restructuring to eliminate 
unreachable 
code, elimination of some gotos, elimination of unused return values, 
some 
additional casting, and removal of redundant declarations.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a 
much larger code and data size.

  Previous Release:
    Non-Debug Version:  87.0K Code, 18.0K Data, 105.0K Total
    Debug Version:     163.4K Code, 50.8K Data, 214.2K Total
  Current Release:
    Non-Debug Version:  87.1K Code, 18.0K Data, 105.1K Total
    Debug Version:     163.5K Code, 50.9K Data, 214.4K Total

2) iASL Compiler/Disassembler and Tools:

No functional changes for this release.

----------------------------------------
14 December 2009. Summary of changes for version 20091214:

1) ACPI CA Core Subsystem:

Enhanced automatic data type conversions for predefined name repairs. 
This 
change expands the automatic repairs/conversions for predefined name 
return 
values to make Integers, Strings, and Buffers fully interchangeable. 
Also, 
a 
Buffer can be converted to a Package of Integers if necessary. The 
nsrepair.c 
module was completely restructured. Lin Ming, Bob Moore.

Implemented automatic removal of null package elements during predefined 
name 
repairs. This change will automatically remove embedded and trailing NULL 
package elements from returned package objects that are defined to 
contain 
a 
variable number of sub-packages. The driver is then presented with a 
package 
with no null elements to deal with. ACPICA BZ 819.

Implemented a repair for the predefined _FDE and _GTM names. The expected 
return value for both names is a Buffer of 5 DWORDs. This repair fixes 
two 
possible problems (both seen in the field), where a package of integers 
is 
returned, or a buffer of BYTEs is returned. With assistance from Jung-uk 
Kim.

Implemented additional module-level code support. This change will 
properly 
execute module-level code that is not at the root of the namespace (under 
a 
Device object, etc.). Now executes the code within the current scope 
instead 
of the root. ACPICA BZ 762. Lin Ming.

Fixed possible mutex acquisition errors when running _REG methods. Fixes 
a 
problem where mutex errors can occur when running a _REG method that is 
in 
the same scope as a method-defined operation region or an operation 
region 
under a module-level IF block. This type of code is rare, so the problem 
has 
not been seen before. ACPICA BZ 826. Lin Ming, Bob Moore.

Fixed a possible memory leak during module-level code execution. An 
object 
could be leaked for each block of executed module-level code if the 
interpreter slack mode is enabled This change deletes any implicitly 
returned 
object from the module-level code block. Lin Ming.

Removed messages for successful predefined repair(s). The repair 
mechanism 
was considered too wordy. Now, messages are only unconditionally emitted 
if 
the return object cannot be repaired. Existing messages for successful 
repairs were converted to ACPI_DEBUG_PRINT messages for now. ACPICA BZ 
827.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a 
much larger code and data size.

  Previous Release:
    Non-Debug Version:  86.6K Code, 18.2K Data, 104.8K Total
    Debug Version:     162.7K Code, 50.8K Data, 213.5K Total
  Current Release:
    Non-Debug Version:  87.0K Code, 18.0K Data, 105.0K Total
    Debug Version:     163.4K Code, 50.8K Data, 214.2K Total

2) iASL Compiler/Disassembler and Tools:

iASL: Fixed a regression introduced in 20091112 where intermediate .SRC 
files 
were no longer automatically removed at the termination of the compile.

acpiexec: Implemented the -f option to specify default region fill value. 
This option specifies the value used to initialize buffers that simulate 
operation regions. Default value is zero. Useful for debugging problems 
that 
depend on a specific initial value for a region or field.

----------------------------------------
12 November 2009. Summary of changes for version 20091112:

1) ACPI CA Core Subsystem:

Implemented a post-order callback to AcpiWalkNamespace. The existing 
interface only has a pre-order callback. This change adds an additional 
parameter for a post-order callback which will be more useful for bus 
scans. 
ACPICA BZ 779. Lin Ming. Updated the ACPICA Programmer Reference.

Modified the behavior of the operation region memory mapping cache for 
SystemMemory. Ensure that the memory mappings created for operation 
regions 
do not cross 4K page boundaries. Crossing a page boundary while mapping 
regions can cause kernel warnings on some hosts if the pages have 
different 
attributes. Such regions are probably BIOS bugs, and this is the 
workaround. 
Linux BZ 14445. Lin Ming.

Implemented an automatic repair for predefined methods that must return 
sorted lists. This change will repair (by sorting) packages returned by 
_ALR, 
_PSS, and _TSS. Drivers can now assume that the packages are correctly 
sorted 
and do not contain NULL package elements. Adds one new file, 
namespace/nsrepair2.c. ACPICA BZ 784. Lin Ming, Bob Moore.

Fixed a possible fault during predefined name validation if a return 
Package 
object contains NULL elements. Also adds a warning if a NULL element is 
followed by any non-null elements. ACPICA BZ 813, 814. Future enhancement 
may 
include repair or removal of all such NULL elements where possible.

Implemented additional module-level executable AML code support. This 
change 
will execute module-level code that is not at the root of the namespace 
(under a Device object, etc.) at table load time. Module-level executable 
AML 
code has been illegal since ACPI 2.0. ACPICA BZ 762. Lin Ming.

Implemented a new internal function to create Integer objects. This 
function 
simplifies miscellaneous object creation code. ACPICA BZ 823.

Reduced the severity of predefined repair messages, Warning to Info. 
Since 
the object was successfully repaired, a warning is too severe. Reduced to 
an 
info message for now. These messages may eventually be changed to debug-
only. 
ACPICA BZ 812.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a 
much larger code and data size.

  Previous Release:
    Non-Debug Version:  85.8K Code, 18.0K Data, 103.8K Total
    Debug Version:     161.8K Code, 50.6K Data, 212.4K Total
  Current Release:
    Non-Debug Version:  86.6K Code, 18.2K Data, 104.8K Total
    Debug Version:     162.7K Code, 50.8K Data, 213.5K Total

2) iASL Compiler/Disassembler and Tools:

iASL: Implemented Switch() with While(1) so that Break works correctly. 
This 
change correctly implements the Switch operator with a surrounding 
While(1) 
so that the Break operator works as expected. ACPICA BZ 461. Lin Ming.

iASL: Added a message if a package initializer list is shorter than 
package 
length. Adds a new remark for a Package() declaration if an initializer 
list 
exists, but is shorter than the declared length of the package. Although 
technically legal, this is probably a coding error and it is seen in the 
field. ACPICA BZ 815. Lin Ming, Bob Moore.

iASL: Fixed a problem where the compiler could fault after the maximum 
number 
of errors was reached (200).

acpixtract: Fixed a possible warning for pointer cast if the compiler 
warning 
level set very high.

----------------------------------------
13 October 2009. Summary of changes for version 20091013:

1) ACPI CA Core Subsystem:

Fixed a problem where an Operation Region _REG method could be executed 
more 
than once. If a custom address space handler is installed by the host 
before 
the "initialize operation regions" phase of the ACPICA initialization, 
any 
_REG methods for that address space could be executed twice. This change 
fixes the problem. ACPICA BZ 427. Lin Ming.

Fixed a possible memory leak for the Scope() ASL operator. When the exact 
invocation of "Scope(\)" is executed (change scope to root), one internal 
operand object was leaked. Lin Ming.

Implemented a run-time repair for the _MAT predefined method. If the _MAT 
return value is defined as a Field object in the AML, and the field
size is less than or equal to the default width of an integer (32 or 
64),_MAT 
can incorrectly return an Integer instead of a Buffer. ACPICA now 
automatically repairs this problem. ACPICA BZ 810.

Implemented a run-time repair for the _BIF and _BIX predefined methods. 
The 
"OEM Information" field is often incorrectly returned as an Integer with 
value zero if the field is not supported by the platform. This is due to 
an 
ambiguity in the ACPI specification. The field should always be a string. 
ACPICA now automatically repairs this problem by returning a NULL string 
within the returned Package. ACPICA BZ 807.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a 
much larger code and data size.

  Previous Release:
    Non-Debug Version:  85.6K Code, 18.0K Data, 103.6K Total
    Debug Version:     161.7K Code, 50.9K Data, 212.6K Total
  Current Release:
    Non-Debug Version:  85.8K Code, 18.0K Data, 103.8K Total
    Debug Version:     161.8K Code, 50.6K Data, 212.4K Total

2) iASL Compiler/Disassembler and Tools:

Disassembler: Fixed a problem where references to external symbols that 
contained one or more parent-prefixes (carats) were not handled 
correctly, 
possibly causing a fault. ACPICA BZ 806. Lin Ming.

Disassembler: Restructured the code so that all functions that handle 
external symbols are in a single module. One new file is added, 
common/dmextern.c.

AML Debugger: Added a max count argument for the Batch command (which 
executes multiple predefined methods within the namespace.)

iASL: Updated the compiler documentation (User Reference.) Available at 
http://www.acpica.org/documentation/. ACPICA BZ 750.

AcpiXtract: Updated for Lint and other formatting changes. Close all open 
files.

----------------------------------------
03 September 2009. Summary of changes for version 20090903:

1) ACPI CA Core Subsystem:

For Windows Vista compatibility, added the automatic execution of an _INI 
method located at the namespace root (\_INI). This method is executed at 
table load time. This support is in addition to the automatic execution 
of 
\_SB._INI. Lin Ming.

Fixed a possible memory leak in the interpreter for AML package objects 
if 
the package initializer list is longer than the defined size of the 
package. 
This apparently can only happen if the BIOS changes the package size on 
the 
fly (seen in a _PSS object), as ASL compilers do not allow this. The 
interpreter will truncate the package to the defined size (and issue an 
error 
message), but previously could leave the extra objects undeleted if they 
were 
pre-created during the argument processing (such is the case if the 
package 
consists of a number of sub-packages as in the _PSS.) ACPICA BZ 805.

Fixed a problem seen when a Buffer or String is stored to itself via ASL. 
This has been reported in the field. Previously, ACPICA would zero out 
the 
buffer/string. Now, the operation is treated as a noop. Provides Windows 
compatibility. ACPICA BZ 803. Lin Ming.

Removed an extraneous error message for ASL constructs of the form 
Store(LocalX,LocalX) when LocalX is uninitialized. These curious 
statements 
are seen in many BIOSs and are once again treated as NOOPs and no error 
is 
emitted when they are encountered. ACPICA BZ 785.

Fixed an extraneous warning message if a _DSM reserved method returns a 
Package object. _DSM can return any type of object, so validation on the 
return type cannot be performed. ACPICA BZ 802.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a 
much larger code and data size.

2) iASL Compiler/Disassembler and Tools:

iASL: Fixed a problem with the use of the Alias operator and Resource 
Templates. The correct alias is now constructed and no error is emitted. 
ACPICA BZ 738.

iASL: Implemented the -I option to specify additional search directories 
for 
include files. Allows multiple additional search paths for include files. 
Directories are searched in the order specified on the command line 
(after 
the local directory is searched.) ACPICA BZ 800.

iASL: Fixed a problem where the full pathname for include files was not 
emitted for warnings/errors. This caused the IDE support to not work 
properly. ACPICA BZ 765.

iASL: Implemented the -@ option to specify a Windows-style response file 
containing additional command line options. ACPICA BZ 801.

AcpiExec: Added support to load multiple AML files simultaneously (such 
as 
a 
DSDT and multiple SSDTs). Also added support for wildcards within the AML 
pathname. These features allow all machine tables to be easily loaded and 
debugged together. ACPICA BZ 804.

Disassembler: Added missing support for disassembly of HEST table Error 
Bank 
subtables. 

----------------------------------------
30 July 2009. Summary of changes for version 20090730:

The ACPI 4.0 implementation for ACPICA is complete with this release.

1) ACPI CA Core Subsystem:

ACPI 4.0: Added header file support for all new and changed ACPI tables. 
Completely new tables are: IBFT, IVRS, MSCT, and WAET. Tables that are 
new 
for ACPI 4.0, but have previously been supported in ACPICA are: CPEP, 
BERT, 
EINJ, ERST, and HEST. Other newly supported tables are: UEFI and WDAT. 
There 
have been some ACPI 4.0 changes to other existing tables. Split the large 
actbl1.h header into the existing actbl2.h header. ACPICA BZ 774.

ACPI 4.0: Implemented predefined name validation for all new names. There 
are 
31 new names in ACPI 4.0. The predefined validation module was split into 
two 
files. The new file is namespace/nsrepair.c. ACPICA BZ 770.

Implemented support for so-called "module-level executable code". This is 
executable AML code that exists outside of any control method and is 
intended 
to be executed at table load time. Although illegal since ACPI 2.0, this 
type 
of code still exists and is apparently still being created. Blocks of 
this 
code are now detected and executed as intended. Currently, the code 
blocks 
must exist under either an If, Else, or While construct; these are the 
typical cases seen in the field. ACPICA BZ 762. Lin Ming.

Implemented an automatic dynamic repair for predefined names that return 
nested Package objects. This applies to predefined names that are defined 
to 
return a variable-length Package of sub-packages. If the number of sub-
packages is one, BIOS code is occasionally seen that creates a simple 
single 
package with no sub-packages. This code attempts to fix the problem by 
wrapping a new package object around the existing package. These methods 
can 
be repaired: _ALR, _CSD, _HPX, _MLS, _PRT, _PSS, _TRT, and _TSS. ACPICA 
BZ 
790.

Fixed a regression introduced in 20090625 for the AcpiGetDevices 
interface. 
The _HID/_CID matching was broken and no longer matched IDs correctly. 
ACPICA 
BZ 793.

Fixed a problem with AcpiReset where the reset would silently fail if the 
register was one of the protected I/O ports. AcpiReset now bypasses the 
port 
validation mechanism. This may eventually be driven into the 
AcpiRead/Write 
interfaces.

Fixed a regression related to the recent update of the AcpiRead/Write 
interfaces. A sleep/suspend could fail if the optional PM2 Control 
register 
does not exist during an attempt to write the Bus Master Arbitration bit. 
(However, some hosts already delete the code that writes this bit, and 
the 
code may in fact be obsolete at this date.) ACPICA BZ 799.

Fixed a problem where AcpiTerminate could fault if inadvertently called 
twice 
in succession. ACPICA BZ 795.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a 
much larger code and data size.

2) iASL Compiler/Disassembler and Tools:

ACPI 4.0: Implemented disassembler support for all new ACPI tables and 
changes to existing tables. ACPICA BZ 775.

----------------------------------------
25 June 2009. Summary of changes for version 20090625:

The ACPI 4.0 Specification was released on June 16 and is available at 
www.acpi.info. ACPICA implementation of ACPI 4.0 is underway and will 
continue for the next few releases.

1) ACPI CA Core Subsystem:

ACPI 4.0: Implemented interpreter support for the IPMI operation region 
address space. Includes support for bi-directional data buffers and an 
IPMI 
address space handler (to be installed by an IPMI device driver.) ACPICA 
BZ 
773. Lin Ming.

ACPI 4.0: Added changes for existing ACPI tables - FACS and SRAT. 
Includes 
support in both the header files and the disassembler.

Completed a major update for the AcpiGetObjectInfo external interface. 
Changes include:
 - Support for variable, unlimited length HID, UID, and CID strings.
 - Support Processor objects the same as Devices (HID,UID,CID,ADR,STA, 
etc.)
 - Call the _SxW power methods on behalf of a device object.
 - Determine if a device is a PCI root bridge.
 - Change the ACPI_BUFFER parameter to ACPI_DEVICE_INFO.
These changes will require an update to all callers of this interface. 
See 
the updated ACPICA Programmer Reference for details. One new source file 
has 
been added - utilities/utids.c. ACPICA BZ 368, 780.

Updated the AcpiRead and AcpiWrite external interfaces to support 64-bit 
transfers. The Value parameter has been extended from 32 bits to 64 bits 
in 
order to support new ACPI 4.0 tables. These changes will require an 
update 
to 
all callers of these interfaces. See the ACPICA Programmer Reference for 
details. ACPICA BZ 768.

Fixed several problems with AcpiAttachData. The handler was not invoked 
when 
the host node was deleted. The data sub-object was not automatically 
deleted 
when the host node was deleted. The interface to the handler had an 
unused 
parameter, this was removed. ACPICA BZ 778.

Enhanced the function that dumps ACPI table headers. All non-printable 
characters in the string fields are now replaced with '?' (Signature, 
OemId, 
OemTableId, and CompilerId.) ACPI tables with non-printable characters in 
these fields are occasionally seen in the field. ACPICA BZ 788.

Fixed a problem with predefined method repair code where the code that 
attempts to repair/convert an object of incorrect type is only executed 
on 
the first time the predefined method is called. The mechanism that 
disables 
warnings on subsequent calls was interfering with the repair mechanism. 
ACPICA BZ 781.

Fixed a possible memory leak in the predefined validation/repair code 
when 
a 
buffer is automatically converted to an expected string object.

Removed obsolete 16-bit files from the distribution and from the current 
git 
tree head. ACPICA BZ 776.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a 
much larger code and data size.

2) iASL Compiler/Disassembler and Tools:

ACPI 4.0: iASL and Disassembler - implemented support for the new IPMI 
operation region keyword. ACPICA BZ 771, 772. Lin Ming.

ACPI 4.0: iASL - implemented compile-time validation support for all new 
predefined names and control methods (31 total). ACPICA BZ 769.

----------------------------------------
21 May 2009. Summary of changes for version 20090521:

1) ACPI CA Core Subsystem:

Disabled the preservation of the SCI enable bit in the PM1 control 
register. 
The SCI enable bit (bit 0, SCI_EN) is defined by the ACPI specification 
to 
be 
a "preserved" bit - "OSPM always preserves this bit position", section 
4.7.3.2.1. However, some machines fail if this bit is in fact preserved 
because the bit needs to be explicitly set by the OS as a workaround. No 
machines fail if the bit is not preserved. Therefore, ACPICA no longer 
attempts to preserve this bit.

Fixed a problem in AcpiRsGetPciRoutingTableLength where an invalid or 
incorrectly formed _PRT package could cause a fault. Added validation to 
ensure that each package element is actually a sub-package.

Implemented a new interface to install or override a single control 
method, 
AcpiInstallMethod. This interface is useful when debugging in order to 
repair 
an existing method or to install a missing method without having to 
override 
the entire ACPI table. See the ACPICA Programmer Reference for use and 
examples. Lin Ming, Bob Moore.

Fixed several reference count issues with the DdbHandle object that is 
created from a Load or LoadTable operator. Prevent premature deletion of 
the 
object. Also, mark the object as invalid once the table has been 
unloaded. 
This is needed because the handle itself may not be deleted after the 
table 
unload, depending on whether it has been stored in a named object by the 
caller. Lin Ming.

Fixed a problem with Mutex Sync Levels. Fixed a problem where if multiple 
mutexes of the same sync level are acquired but then not released in 
strict 
opposite order, the internally maintained Current Sync Level becomes 
confused 
and can cause subsequent execution errors. ACPICA BZ 471.

Changed the allowable release order for ASL mutex objects. The ACPI 4.0 
specification has been changed to make the SyncLevel for mutex objects 
more 
useful. When releasing a mutex, the SyncLevel of the mutex must now be 
the 
same as the current sync level. This makes more sense than the previous 
rule 
(SyncLevel less than or equal). This change updates the code to match the 
specification.

Fixed a problem with the local version of the AcpiOsPurgeCache function. 
The 
(local) cache must be locked during all cache object deletions. Andrew 
Baumann.

Updated the Load operator to use operation region interfaces. This 
replaces 
direct memory mapping with region access calls. Now, all region accesses 
go 
through the installed region handler as they should.

Simplified and optimized the NsGetNextNode function. Reduced parameter 
count 
and reduced code for this frequently used function.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a 
much larger code and data size.

  Previous Release:

    Debug Version:     158.9K Code, 50.0K Data, 208.9K Total

2) iASL Compiler/Disassembler and Tools:

Disassembler: Fixed some issues with DMAR, HEST, MADT tables. Some 
problems 
with sub-table disassembly and handling invalid sub-tables. Attempt 
recovery 
after an invalid sub-table ID.

----------------------------------------
22 April 2009. Summary of changes for version 20090422:

1) ACPI CA Core Subsystem:

Fixed a compatibility issue with the recently released I/O port 
protection 
mechanism. For windows compatibility, 1) On a port protection violation, 
simply ignore the request and do not return an exception (allow the 
control 
method to continue execution.) 2) If only part of the request overlaps a 
protected port, read/write the individual ports that are not protected. 
Linux 
BZ 13036. Lin Ming

Enhanced the execution of the ASL/AML BreakPoint operator so that it 
actually 
breaks into the AML debugger if the debugger is present. This matches the 
ACPI-defined behavior.

Fixed several possible warnings related to the use of the configurable 
ACPI_THREAD_ID. This type can now be configured as either an integer or a 
pointer with no warnings. Also fixes several warnings in printf-like 
statements for the 64-bit build when the type is configured as a pointer. 
ACPICA BZ 766, 767.

Fixed a number of possible warnings when compiling with gcc 4+ (depending 
on 
warning options.) Examples include printf formats, aliasing, unused 
globals, 
missing prototypes, missing switch default statements, use of non-ANSI 
library functions, use of non-ANSI constructs. See generate/unix/Makefile 
for 
a list of warning options used with gcc 3 and 4. ACPICA BZ 735.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a 
much larger code and data size.

    Debug Version:     158.0K Code, 49.9K Data, 207.9K Total

2) iASL Compiler/Disassembler and Tools:

iASL: Fixed a generation warning from Bison 2.3 and fixed several 
warnings 
on 
the 64-bit build.

iASL: Fixed a problem where the Unix/Linux versions of the compiler could 
not 
correctly digest Windows/DOS formatted files (with CR/LF).

iASL: Added a new option for "quiet mode" (-va) that produces only the 
compilation summary, not individual errors and warnings. Useful for large 
batch compilations.

AcpiExec: Implemented a new option (-z) to enable a forced 
semaphore/mutex 
timeout that can be used to detect hang conditions during execution of 
AML 
code (includes both internal semaphores and AML-defined mutexes and 
events.)

Added new makefiles for the generation of acpica in a generic unix-like 
environment. These makefiles are intended to generate the acpica tools 
and 
utilities from the original acpica git source tree structure.

Test Suites: Updated and cleaned up the documentation files. Updated the 
copyrights to 2009, affecting all source files. Use the new version of 
iASL 
with quiet mode. Increased the number of available semaphores in the 
Windows 
OSL, allowing the aslts to execute fully on Windows. For the Unix OSL, 
added 
an alternate implementation of the semaphore timeout to allow aslts to 
execute fully on Cygwin.

----------------------------------------
20 March 2009. Summary of changes for version 20090320:

1) ACPI CA Core Subsystem:

Fixed a possible race condition between AcpiWalkNamespace and dynamic 
table 
unloads. Added a reader/writer locking mechanism to allow multiple 
concurrent 
namespace walks (readers), but block a dynamic table unload until it can 
gain 
exclusive write access to the namespace. This fixes a problem where a 
table 
unload could (possibly catastrophically) delete the portion of the 
namespace 
that is currently being examined by a walk. Adds a new file, utlock.c, 
that 
implements the reader/writer lock mechanism. ACPICA BZ 749.

Fixed a regression introduced in version 20090220 where a change to the 
FADT 
handling could cause the ACPICA subsystem to access non-existent I/O 
ports.

Modified the handling of FADT register and table (FACS/DSDT) addresses. 
The 
FADT can contain both 32-bit and 64-bit versions of these addresses. 
Previously, the 64-bit versions were favored, meaning that if both 32 and 
64 
versions were valid, but not equal, the 64-bit version was used. This was 
found to cause some machines to fail. Now, in this case, the 32-bit 
version 
is used instead. This now matches the Windows behavior.

Implemented a new mechanism to protect certain I/O ports. Provides 
Microsoft 
compatibility and protects the standard PC I/O ports from access via AML 
code. Adds a new file, hwvalid.c

Fixed a possible extraneous warning message from the FADT support. The 
message warns of a 32/64 length mismatch between the legacy and GAS 
definitions for a register.

Removed the obsolete AcpiOsValidateAddress OSL interface. This interface 
is 
made obsolete by the port protection mechanism above. It was previously 
used 
to validate the entire address range of an operation region, which could 
be 
incorrect if the range included illegal ports, but fields within the 
operation region did not actually access those ports. Validation is now 
performed on a per-field basis instead of the entire region.

Modified the handling of the PM1 Status Register ignored bit (bit 11.) 
Ignored bits must be "preserved" according to the ACPI spec. Usually, 
this 
means a read/modify/write when writing to the register. However, for 
status 
registers, writing a one means clear the event. Writing a zero means 
preserve 
the event (do not clear.) This behavior is clarified in the ACPI 4.0 
spec, 
and the ACPICA code now simply always writes a zero to the ignored bit.

Modified the handling of ignored bits for the PM1 A/B Control Registers. 
As 
per the ACPI specification, for the control registers, preserve 
(read/modify/write) all bits that are defined as either reserved or 
ignored.

Updated the handling of write-only bits in the PM1 A/B Control Registers. 
When reading the register, zero the write-only bits as per the ACPI spec. 
ACPICA BZ 443. Lin Ming.

Removed "Linux" from the list of supported _OSI strings. Linux no longer 
wants to reply true to this request. The Windows strings are the only 
paths 
through the AML that are tested and known to work properly.

2) iASL Compiler/Disassembler and Tools:

Acpiexec: Split the large aeexec.c file into two new files, aehandlers.c 
and 
aetables.c

----------------------------------------
20 February 2009. Summary of changes for version 20090220:

1) ACPI CA Core Subsystem:

Optimized the ACPI register locking. Removed locking for reads from the 
ACPI 
bit registers in PM1 Status, Enable, Control, and PM2 Control. The lock 
is 
not required when reading the single-bit registers. The 
AcpiGetRegisterUnlocked function is no longer needed and has been 
removed. 
This will improve performance for reads on these registers. ACPICA BZ 
760.

Fixed the parameter validation for AcpiRead/Write. Now return 
AE_BAD_PARAMETER if the input register pointer is null, and 
AE_BAD_ADDRESS 
if 
the register has an address of zero. Previously, these cases simply 
returned 
AE_OK. For optional registers such as PM1B status/enable/control, the 
caller 
should check for a valid register address before calling. ACPICA BZ 748.

Renamed the external ACPI bit register access functions. Renamed 
AcpiGetRegister and AcpiSetRegister to clarify the purpose of these 
functions. The new names are AcpiReadBitRegister and 
AcpiWriteBitRegister. 
Also, restructured the code for these functions by simplifying the code 
path 
and condensing duplicate code to reduce code size.

Added new functions to transparently handle the possibly split PM1 A/B 
registers. AcpiHwReadMultiple and AcpiHwWriteMultiple. These two 
functions 
now handle the split registers for PM1 Status, Enable, and Control. 
ACPICA 
BZ 
746.

Added a function to handle the PM1 control registers, 
AcpiHwWritePm1Control. 
This function writes both of the PM1 control registers (A/B). These 
registers 
are different than the PM1 A/B status and enable registers in that 
different 
values can be written to the A/B registers. Most notably, the SLP_TYP 
bits 
can be different, as per the values returned from the _Sx predefined 
methods.

Removed an extra register write within AcpiHwClearAcpiStatus. This 
function 
was writing an optional PM1B status register twice. The existing call to 
the 
low-level AcpiHwRegisterWrite automatically handles a possibly split PM1 
A/B 
register. ACPICA BZ 751.

Split out the PM1 Status registers from the FADT. Added new globals for 
these 
registers (A/B), similar to the way the PM1 Enable registers are handled. 
Instead of overloading the FADT Event Register blocks. This makes the 
code 
clearer and less prone to error.

Fixed the warning message for when the platform contains too many ACPI 
tables 
for the default size of the global root table data structure. The 
calculation 
for the truncation value was incorrect.

Removed the ACPI_GET_OBJECT_TYPE macro. Removed all instances of this 
obsolete macro, since it is now a simple reference to ->common.type. 
There 
were about 150 invocations of the macro across 41 files. ACPICA BZ 755.

Removed the redundant ACPI_BITREG_SLEEP_TYPE_B. This type is the same as 
TYPE_A. Removed this and all related instances. Renamed SLEEP_TYPE_A to 
simply SLEEP_TYPE. ACPICA BZ 754.

Conditionally compile the AcpiSetFirmwareWakingVector64 function. This 
function is only needed on 64-bit host operating systems and is thus not 
included for 32-bit hosts.

Debug output: print the input and result for invocations of the _OSI 
reserved 
control method via the ACPI_LV_INFO debug level. Also, reduced some of 
the 
verbosity of this debug level. Len Brown.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a 
much larger code and data size.

2) iASL Compiler/Disassembler and Tools:

Disassembler: Decode the FADT PM_Profile field. Emit ascii names for the 
various legal performance profiles.

----------------------------------------
23 January 2009. Summary of changes for version 20090123:

1) ACPI CA Core Subsystem:

Added the 2009 copyright to all module headers and signons. This affects 
virtually every file in the ACPICA core subsystem, the iASL compiler, and 
the tools/utilities.

Implemented a change to allow the host to override any ACPI table, 
including 
dynamically loaded tables. Previously, only the DSDT could be replaced by 
the 
host. With this change, the AcpiOsTableOverride interface is called for 
each 
table found in the RSDT/XSDT during ACPICA initialization, and also 
whenever 
a table is dynamically loaded via the AML Load operator.

Updated FADT flag definitions, especially the Boot Architecture flags.

Debugger: For the Find command, automatically pad the input ACPI name 
with 
underscores if the name is shorter than 4 characters. This enables a 
match 
with the actual namespace entry which is itself padded with underscores.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a 
much larger code and data size.

2) iASL Compiler/Disassembler and Tools:

Fix build error under Bison-2.4.

Dissasembler: Enhanced FADT support. Added decoding of the Boot 
Architecture 
flags. Now decode all flags, regardless of the FADT version. Flag output 
includes the FADT version which first defined each flag.

The iASL -g option now dumps the RSDT to a file (in addition to the FADT 
and 
DSDT). Windows only.

----------------------------------------
04 December 2008. Summary of changes for version 20081204:

1) ACPI CA Core Subsystem:

The ACPICA Programmer Reference has been completely updated and revamped 
for 
this release. This includes updates to the external interfaces, OSL 
interfaces, the overview sections, and the debugger reference.

Several new ACPICA interfaces have been implemented and documented in the 
programmer reference:
AcpiReset - Writes the reset value to the FADT-defined reset register.
AcpiDisableAllGpes - Disable all available GPEs.
AcpiEnableAllRuntimeGpes - Enable all available runtime GPEs.
AcpiGetGpeDevice - Get the GPE block device associated with a GPE.
AcpiGbl_CurrentGpeCount - Tracks the current number of available GPEs.
AcpiRead - Low-level read ACPI register (was HwLowLevelRead.)
AcpiWrite - Low-level write ACPI register (was HwLowLevelWrite.)

Most of the public ACPI hardware-related interfaces have been moved to a 
new 
file, components/hardware/hwxface.c

Enhanced the FADT parsing and low-level ACPI register access: The ACPI 
register lengths within the FADT are now used, and the low level ACPI 
register access no longer hardcodes the ACPI register lengths. Given that 
there may be some risk in actually trusting the FADT register lengths, a 
run-
time option was added to fall back to the default hardcoded lengths if 
the 
FADT proves to contain incorrect values - UseDefaultRegisterWidths. This 
option is set to true for now, and a warning is issued if a suspicious 
FADT 
register length is overridden with the default value.

Fixed a reference count issue in NsRepairObject. This problem was 
introduced 
in version 20081031 as part of a fix to repair Buffer objects within 
Packages. Lin Ming.

Added semaphore support to the Linux/Unix application OS-services layer 
(OSL). ACPICA BZ 448. Lin Ming.

Added the ACPI_MUTEX_TYPE configuration option to select whether mutexes 
will 
be implemented in the OSL, or will binary semaphores be used instead.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a 
much larger code and data size.

BZ 743.

Disassembler: Updates for several ACPI data tables (HEST, EINJ, and 
MCFG).

----------------------------------------
31 October 2008. Summary of changes for version 20081031:

1) ACPI CA Core Subsystem:

Restructured the ACPICA header files into public/private. acpi.h now 
includes 
only the "public" acpica headers. All other acpica headers are "private" 
and 
should not be included by acpica users. One new file, accommon.h is used 
to 
include the commonly used private headers for acpica code generation. 
Future 
plans include moving all private headers to a new subdirectory.

Implemented an automatic Buffer->String return value conversion for 
predefined ACPI methods. For these methods (such as _BIF), added 
automatic 
conversion for return objects that are required to be a String, but a 
Buffer 
was found instead. This can happen when reading string battery data from 
an 
operation region, because it used to be difficult to convert the data 
from 
buffer to string from within the ASL. Ensures that the host OS is 
provided 
with a valid null-terminated string. Linux BZ 11822.

Updated the FACS waking vector interfaces. Split 
AcpiSetFirmwareWakingVector 
into two: one for the 32-bit vector, another for the 64-bit vector. This 
is 
required because the host OS must setup the wake much differently for 
each 
vector (real vs. protected mode, etc.) and the interface itself should 
not 
be 
deciding which vector to use. Also, eliminated the 
GetFirmwareWakingVector 
interface, as it served no purpose (only the firmware reads the vector, 
OS 
only writes the vector.) ACPICA BZ 731.

Implemented a mechanism to escape infinite AML While() loops. Added a 
loop 
counter to force exit from AML While loops if the count becomes too 
large. 
This can occur in poorly written AML when the hardware does not respond 
within a while loop and the loop does not implement a timeout. The 
maximum 
loop count is configurable. A new exception code is returned when a loop 
is 
broken, AE_AML_INFINITE_LOOP. Alexey Starikovskiy, Bob Moore.

Optimized the execution of AML While loops. Previously, a control state 
object was allocated and freed for each execution of the loop. The 
optimization is to simply reuse the control state for each iteration. 
This 
speeds up the raw loop execution time by about 5%.

Enhanced the implicit return mechanism. For Windows compatibility, return 
an 
implicit integer of value zero for methods that contain no executable 
code. 
Such methods are seen in the field as stubs (presumably), and can cause 
drivers to fail if they expect a return value. Lin Ming.

Allow multiple backslashes as root prefixes in namepaths. In a fully 
qualified namepath, allow multiple backslash prefixes. This can happen 
(and 
is seen in the field) because of the use of a double-backslash in strings 
(since backslash is the escape character) causing confusion. ACPICA BZ 
739 
Lin Ming.

Emit a warning if two different FACS or DSDT tables are discovered in the 
FADT. Checks if there are two valid but different addresses for the FACS 
and 
DSDT within the FADT (mismatch between the 32-bit and 64-bit fields.)

Consolidated the method argument count validation code. Merged the code 
that 
validates control method argument counts into the predefined validation 
module. Eliminates possible multiple warnings for incorrect argument 
counts.

Implemented ACPICA example code. Includes code for ACPICA initialization, 
handler installation, and calling a control method. Available at 
source/tools/examples.

Added a global pointer for FACS table to simplify internal FACS access. 
Use 
the global pointer instead of using AcpiGetTableByIndex for each FACS 
access. 
This simplifies the code for the Global Lock and the Firmware Waking 
Vector(s).

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a 
much larger code and data size.

    Non-Debug Version:  81.2K Code, 17.0K Data,  98.2K Total
    Debug Version:     155.8K Code, 49.1K Data, 204.9K Total
  Current Release:
    Non-Debug Version:  81.7K Code, 17.3K Data,  99.0K Total
    Debug Version:     156.4K Code, 49.4K Data, 205.8K Total

2) iASL Compiler/Disassembler and Tools:

iASL: Improved disassembly of external method calls. Added the -e option 
to 
allow the inclusion of additional ACPI tables to help with the 
disassembly 
of 
method invocations and the generation of external declarations during the 
disassembly. Certain external method invocations cannot be disassembled 
properly without the actual declaration of the method. Use the -e option 
to 
include the table where the external method(s) are actually declared. 
Most 
useful for disassembling SSDTs that make method calls back to the master 
DSDT. Lin Ming. Example: To disassemble an SSDT with calls to DSDT:  iasl 
-d 
-e dsdt.aml ssdt1.aml

iASL: Fix to allow references to aliases within ASL namepaths. Fixes a 
problem where the use of an alias within a namepath would result in a not 
found error or cause the compiler to fault. Also now allows forward 
references from the Alias operator itself. ACPICA BZ 738.

----------------------------------------
26 September 2008. Summary of changes for version 20080926:

1) ACPI CA Core Subsystem:

Designed and implemented a mechanism to validate predefined ACPI methods 
and 
objects. This code validates the predefined ACPI objects (objects whose 
names 
start with underscore) that appear in the namespace, at the time they are 
evaluated. The argument count and the type of the returned object are 
validated against the ACPI specification. The purpose of this validation 
is 
to detect problems with the BIOS-implemented predefined ACPI objects 
before 
the results are returned to the ACPI-related drivers. Future enhancements 
may 
include actual repair of incorrect return objects where possible. Two new 
files are nspredef.c and acpredef.h.

Fixed a fault in the AML parser if a memory allocation fails during the 
Op 
completion routine AcpiPsCompleteThisOp. Lin Ming. ACPICA BZ 492.

Fixed an issue with implicit return compatibility. This change improves 
the 
implicit return mechanism to be more compatible with the MS interpreter. 
Lin 
Ming, ACPICA BZ 349.

Implemented support for zero-length buffer-to-string conversions. Allow 
zero 
length strings during interpreter buffer-to-string conversions. For 
example, 
during the ToDecimalString and ToHexString operators, as well as implicit 
conversions. Fiodor Suietov, ACPICA BZ 585.

Fixed two possible memory leaks in the error exit paths of 
AcpiUtUpdateObjectReference and AcpiUtWalkPackageTree. These functions 
are 
similar in that they use a stack of state objects in order to eliminate 
recursion. The stack must be fully unwound and deallocated if an error 
occurs. Lin Ming. ACPICA BZ 383.

Removed the unused ACPI_BITREG_WAKE_ENABLE definition and entry in the 
global 
ACPI register table. This bit does not exist and is unused. Lin Ming, Bob 
Moore ACPICA BZ 442.

Removed the obsolete version number in module headers. Removed the 
"$Revision" number that appeared in each module header. This version 
number 
was useful under SourceSafe and CVS, but has no meaning under git. It is 
not 
only incorrect, it could also be misleading.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a 
much larger code and data size.

    Debug Version:     155.8K Code, 49.1K Data, 204.9K Total

----------------------------------------
29 August 2008. Summary of changes for version 20080829:

1) ACPI CA Core Subsystem:

Completed a major cleanup of the internal ACPI_OPERAND_OBJECT of type 
Reference. Changes include the elimination of cheating on the Object 
field 
for the DdbHandle subtype, addition of a reference class field to 
differentiate the various reference types (instead of an AML opcode), and 
the 
cleanup of debug output for this object. Lin Ming, Bob Moore. BZ 723

Reduce an error to a warning for an incorrect method argument count. 
Previously aborted with an error if too few arguments were passed to a 
control method via the external ACPICA interface. Now issue a warning 
instead 
and continue. Handles the case where the method inadvertently declares 
too 
many arguments, but does not actually use the extra ones. Applies mainly 
to 
the predefined methods. Lin Ming. Linux BZ 11032.

Disallow the evaluation of named object types with no intrinsic value. 
Return 
AE_TYPE for objects that have no value and therefore evaluation is 
undefined: 
Device, Event, Mutex, Region, Thermal, and Scope. Previously, evaluation 
of 
these types were allowed, but an exception would be generated at some 
point 
during the evaluation. Now, the error is generated up front.

Fixed a possible memory leak in the AcpiNsGetExternalPathname function 
(nsnames.c). Fixes a leak in the error exit path.

Removed the obsolete debug levels ACPI_DB_WARN and ACPI_DB_ERROR. These 
debug 
levels were made obsolete by the ACPI_WARNING, ACPI_ERROR, and 
ACPI_EXCEPTION 
interfaces. Also added ACPI_DB_EVENTS to correspond with the existing 
ACPI_LV_EVENTS.

Removed obsolete and/or unused exception codes from the acexcep.h header. 
There is the possibility that certain device drivers may be affected if 
they 
use any of these exceptions.

The ACPICA documentation has been added to the public git source tree, 
under 
acpica/documents. Included are the ACPICA programmer reference, the iASL 
compiler reference, and the changes.txt release logfile.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a 
much larger code and data size.

  Previous Release:
    Non-Debug Version:  79.7K Code, 16.4K Data,  96.1K Total
    Debug Version:     153.9K Code, 48.4K Data, 202.3K Total
  Current Release:
    Non-Debug Version:  79.7K Code, 16.4K Data,  96.1K Total
    Debug Version:     153.7K Code, 48.2K Data, 201.9K Total

2) iASL Compiler/Disassembler and Tools:

Allow multiple argument counts for the predefined _SCP method. ACPI 3.0 
defines _SCP with 3 arguments. Previous versions defined it with only 1 
argument. iASL now allows both definitions.

iASL/disassembler: avoid infinite loop on bad ACPI tables. Check for 
zero-
length subtables when disassembling ACPI tables. Also fixed a couple of 
errors where a full 16-bit table type field was not extracted from the 
input 
properly.

acpisrc: Improve comment counting mechanism for generating source code 
statistics. Count first and last lines of multi-line comments as 
whitespace, 
not comment lines. Handle Linux legal header in addition to standard 
acpica 
header.

----------------------------------------

29 July 2008. Summary of changes for version 20080729:

1) ACPI CA Core Subsystem:

Fix a possible deadlock in the GPE dispatch. Remove call to 
AcpiHwDisableAllGpes during wake in AcpiEvGpeDispatch. This call will 
attempt 
to acquire the GPE lock but can deadlock since the GPE lock is already 
held 
at dispatch time. This code was introduced in version 20060831 as a 
response 
to Linux BZ 6881 and has since been removed from Linux.

Add a function to dereference returned reference objects. Examines the 
return 
object from a call to AcpiEvaluateObject. Any Index or RefOf references 
are 
automatically dereferenced in an attempt to return something useful 
(these 
reference types cannot be converted into an external ACPI_OBJECT.) 
Provides 
MS compatibility. Lin Ming, Bob Moore. Linux BZ 11105

x2APIC support: changes for MADT and SRAT ACPI tables. There are 2 new 
subtables for the MADT and one new subtable for the SRAT. Includes 
disassembler and AcpiSrc support. Data from the Intel 64 Architecture 
x2APIC 
Specification, June 2008.

Additional error checking for pathname utilities. Add error check after 
all 
calls to AcpiNsGetPathnameLength. Add status return from 
AcpiNsBuildExternalPath and check after all calls. Add parameter 
validation 
to AcpiUtInitializeBuffer. Reported by and initial patch by Ingo Molnar.

Return status from the global init function AcpiUtGlobalInitialize. This 
is 
used by both the kernel subsystem and the utilities such as iASL 
compiler. 
The function could possibly fail when the caches are initialized. Yang 
Yi.

Add a function to decode reference object types to strings. Created for 
improved error messages. 

Improve object conversion error messages. Better error messages during 
object 
conversion from internal to the external ACPI_OBJECT. Used for external 
calls 
to AcpiEvaluateObject.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a 
much larger code and data size.

  Previous Release:
    Non-Debug Version:  79.6K Code, 16.2K Data,  95.8K Total
    Debug Version:     153.5K Code, 48.2K Data, 201.7K Total
  Current Release:
    Non-Debug Version:  79.7K Code, 16.4K Data,  96.1K Total
    Debug Version:     153.9K Code, 48.4K Data, 202.3K Total

2) iASL Compiler/Disassembler and Tools:

Debugger: fix a possible hang when evaluating non-methods. Fixes a 
problem 
introduced in version 20080701. If the object being evaluated (via 
execute 
command) is not a method, the debugger can hang while trying to obtain 
non-
existent parameters.

iASL: relax error for using reserved "_T_x" identifiers. These names can 
appear in a disassembled ASL file if they were emitted by the original 
compiler. Instead of issuing an error or warning and forcing the user to 
manually change these names, issue a remark instead.

iASL: error if named object created in while loop. Emit an error if any 
named 
object is created within a While loop. If allowed, this code will 
generate 
a 
run-time error on the second iteration of the loop when an attempt is 
made 
to 
create the same named object twice. ACPICA bugzilla 730.

iASL: Support absolute pathnames for include files. Add support for 
absolute 
pathnames within the Include operator. previously, only relative 
pathnames 
were supported.

iASL: Enforce minimum 1 interrupt in interrupt macro and Resource 
Descriptor. 
The ACPI spec requires one interrupt minimum. BZ 423

iASL: Handle a missing ResourceSource arg, with a present SourceIndex. 
Handles the case for the Interrupt Resource Descriptor where
the ResourceSource argument is omitted but ResourceSourceIndex
is present. Now leave room for the Index. BZ 426

iASL: Prevent error message if CondRefOf target does not exist. Fixes 
cases 
where an error message is emitted if the target does not exist. BZ 516

iASL: Fix broken -g option (get Windows ACPI tables). Fixes the -g option 
(get ACPI tables on Windows). This was apparently broken in version 
20070919.

AcpiXtract: Handle EOF while extracting data. Correctly handle the case 
where 
the EOF happens immediately after the last table in the input file. Print 
completion message. Previously, no message was displayed in this case.

----------------------------------------
01 July 2008. Summary of changes for version 20080701:

0) Git source tree / acpica.org

Fixed a problem where a git-clone from http would not transfer the entire 
source tree.

1) ACPI CA Core Subsystem:

Implemented a "careful" GPE disable in AcpiEvDisableGpe, only modify one 
enable bit. Now performs a read-change-write of the enable register 
instead 
of simply writing out the cached enable mask. This will prevent 
inadvertent 
enabling of GPEs if a rogue GPE is received during initialization (before 
GPE 
handlers are installed.)

Implemented a copy for dynamically loaded tables. Previously, dynamically 
loaded tables were simply mapped - but on some machines this memory is 
corrupted after suspend. Now copy the table to a local buffer. For the 
OpRegion case, added checksum verify. Use the table length from the table 
header, not the region length. For the Buffer case, use the table length 
also. Dennis Noordsij, Bob Moore. BZ 10734

Fixed a problem where the same ACPI table could not be dynamically loaded 
and 
unloaded more than once. Without this change, a table cannot be loaded 
again 
once it has been loaded/unloaded one time. The current mechanism does not 
unregister a table upon an unload. During a load, if the same table is 
found, 
this no longer returns an exception. BZ 722

Fixed a problem where the wrong descriptor length was calculated for the 
EndTag descriptor in 64-bit mode. The "minimal" descriptors such as 
EndTag 
are calculated as 12 bytes long, but the actual length in the internal 
descriptor is 16 because of the round-up to 8 on the 64-bit build. 
Reported 
by Linn Crosetto. BZ 728

Fixed a possible memory leak in the Unload operator. The DdbHandle 
returned 
by Load() did not have its reference count decremented during unload, 
leading 
to a memory leak. Lin Ming. BZ 727

Fixed a possible memory leak when deleting thermal/processor objects. Any 
associated notify handlers (and objects) were not being deleted. Fiodor 
Suietov. BZ 506

Fixed the ordering of the ASCII names in the global mutex table to match 
the 
actual mutex IDs. Used by AcpiUtGetMutexName, a function used for debug 
only. 
Vegard Nossum. BZ 726

Enhanced the AcpiGetObjectInfo interface to return the number of required 
arguments if the object is a control method. Added this call to the 
debugger 
so the proper number of default arguments are passed to a method. This 
prevents a warning when executing methods from AcpiExec.

Added a check for an invalid handle in AcpiGetObjectInfo. Return 
AE_BAD_PARAMETER if input handle is invalid. BZ 474

Fixed an extraneous warning from exconfig.c on the 64-bit build.

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a 
much larger code and data size.

  Previous Release:
    Non-Debug Version:  79.3K Code, 16.2K Data,  95.5K Total

    Debug Version:     153.5K Code, 48.2K Data, 201.7K Total

2) iASL Compiler/Disassembler and Tools:

iASL: Added two missing ACPI reserved names. Added _MTP and _ASZ, both 
resource descriptor names.

iASL: Detect invalid ASCII characters in input (windows version). Removed 
the 
"-CF" flag from the flex compile, enables correct detection of non-ASCII 
characters in the input. BZ 441

iASL: Eliminate warning when result of LoadTable is not used. Eliminate 
the 
"result of operation not used" warning when the DDB handle returned from 
LoadTable is not used. The warning is not needed. BZ 590

AcpiExec: Add support for dynamic table load/unload. Now calls _CFG 
method 
to 
pass address of table to the AML. Added option to disable OpRegion 
simulation 
to allow creation of an OpRegion with a real address that was passed to 
_CFG. 
All of this allows testing of the Load and Unload operators from 
AcpiExec.

Debugger: update tables command for unloaded tables. Handle unloaded 
tables 
and use the standard table header output routine.

----------------------------------------
09 June 2008. Summary of changes for version 20080609:

1) ACPI CA Core Subsystem:

Implemented a workaround for reversed _PRT entries. A significant number 
of 
BIOSs erroneously reverse the _PRT SourceName and the SourceIndex. This 
change dynamically detects and repairs this problem. Provides 
compatibility 
with MS ACPI. BZ 6859

Simplified the internal ACPI hardware interfaces to eliminate the locking 
flag parameter from Register Read/Write. Added a new external interface, 
AcpiGetRegisterUnlocked.

Fixed a problem where the invocation of a GPE control method could hang. 
This 
was a regression introduced in 20080514. The new method argument count 
validation mechanism can enter an infinite loop when a GPE method is 
dispatched. Problem fixed by removing the obsolete code that passed GPE 
block 
information to the notify handler via the control method parameter 
pointer.

Fixed a problem where the _SST execution status was incorrectly returned 
to 
the caller of AcpiEnterSleepStatePrep. This was a regression introduced 
in 
20080514. _SST is optional and a NOT_FOUND exception should never be 
returned. BZ 716

Fixed a problem where a deleted object could be accessed from within the 
AML 
parser. This was a regression introduced in version 20080123 as a fix for 
the 
Unload operator. Lin Ming. BZ 10669

Cleaned up the debug operand dump mechanism. Eliminated unnecessary 
operands 
and eliminated the use of a negative index in a loop. Operands are now 
displayed in the correct order, not backwards. This also fixes a 
regression 
introduced in 20080514 on 64-bit systems where the elimination of 
ACPI_NATIVE_UINT caused the negative index to go large and positive. BZ 
715

Fixed a possible memory leak in EvPciConfigRegionSetup where the error 
exit 
path did not delete a locally allocated structure.

Updated definitions for the DMAR and SRAT tables to synchronize with the 
current specifications. Includes disassembler support.

Fixed a problem in the mutex debug code (in utmutex.c) where an incorrect 
loop termination value was used. Loop terminated on iteration early, 
missing 
one mutex. Linn Crosetto

Example Code and Data Size: These are the sizes for the OS-independent 
acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 
debug version of the code includes the debug output trace mechanism and 
has a 
much larger code and data size.

    Debug Version:     153.0K Code, 48.2K Data, 201.2K Total

2) iASL Compiler/Disassembler and Tools:

Disassembler: Implemented support for EisaId() within _CID objects. Now 
disassemble integer _CID objects back to EisaId invocations, including 
multiple integers within _CID packages. Includes single-step support for 
debugger also.

Disassembler: Added support for DMAR and SRAT table definition changes.

----------------------------------------
14 May 2008. Summary of changes for version 20080514:

1) ACPI CA Core Subsystem:

Fixed a problem where GPEs w
