use it as well for errors.

Use AcpiUtStrupr() instead of strupr() as the latter will disappear in

2005-04-14T06:50:13+00:00

future versions of acpica.

Add the acpi_ec_read and write methods. This allows an external driver

2005-03-20T01:27:27+00:00

(like an EC/SMbus controller) to access the EC address space.  Access
is synchronized by the EcLock/Unlock routines in EcSpaceHandler().

Since the GPE handler is directly called by ACPI-CA and it may have unknown

2005-02-21T23:38:41+00:00

locks held, specify the ACPI_ISR flag to keep it from acquiring any more
mutexes (which could potentially sleep.)  This should fix "could sleep"
warning messages on the following path:

    msleep()
    AcpiOsWaitSemaphore()
    AcpiUtAcquireMutex()
    AcpiDisableGpe()
    EcGpeHandler()
    AcpiEvGpeDispatch()
    AcpiEvGpeDetect()
    AcpiEvGpeDetect()
    AcpiEvSciXruptHandler()

MPSAFE locking

* Use the common serialization macros instead of rolling our own.
* Increase the coverage of the lock in EcSpaceHandler() to cover the entire
  loop to avoid dropping the lock when reading more than one byte.

Remove duplicate FreeBSD id.

Get rid of the strict aliasing error by retrieving the ECDT via a table

2004-07-02T19:17:27+00:00

header pointer and then casting it to the ecdt pointer.  This fixes the
-O2 build.  I'm unsure what changed recently to reveal this error since
this code has been unchanged for months.
