Summary of changes for version 20101209: +12 January 2011. Summary of changes for version 20110112: + +1) ACPI CA Core Subsystem: -This release is available at www.acpica.org/downloads +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.
