cfd820d382 Fix a bug about the cooling system controlling in acpi_thermal driver. 
Recent version of ACPI CA returns the package object which contains
object reference elements if the elements are named objects.
We need to be careful when you use acpi_ForeachPackageObject() in new
code...

b4a052380f Brutally deal with __func__ being 'const char *' on gcc-3.1. 2002-05-19 06:16:47 +00:00

741ef403c2 Match namespace cleanup changes in ACPI CA 20020217 update. 
Use ACPI_SUCCESS/ACPI_FAILURE consistently.
The AcpiGetInto* interfaces are obsoleted by ACPI_ALLOCATE_BUFFER.

c573e654b7 Add OS layer ACPI mutex and threading support. 
- Temporary fix a bug of Intel ACPI CA core code.
 - Add OS layer ACPI mutex support.  This can be disabled by
   specifying option ACPI_NO_SEMAPHORES.
 - Add ACPI threading support.  Now that we have a dedicate taskqueue for
   ACPI tasks and more ACPI task threads can be created by specifying option
   ACPI_MAX_THREADS.
 - Change acpi_EvaluateIntoBuffer() behavior slightly to reuse given
   caller's buffer unless AE_BUFFER_OVERFLOW occurs.  Also CM battery's
   evaluations were changed to use acpi_EvaluateIntoBuffer().
 - Add new utility function acpi_ConvertBufferToInteger().
 - Add simple locking for CM battery and temperature updating.
 - Fix a minor problem on EC locking.
 - Make the thermal zone polling rate to be changeable.
 - Change minor things on AcpiOsSignal(); in ACPI_SIGNAL_FATAL case,
   entering Debugger is easier to investigate the problem rather than panic.

4c1cdee628 Updates to match the ACPI CA 20010816 import: 
- New debug macro (ACPI_DEBUG_PRINT), reducing debug-case code size.
 - New debug level/subsystem codes.

eb5b463449 Fix error checking about device state transition from D0 to D3. 
Turn off the resources listed in _PR0 to go to D3 if we don't have _PR3/_PS3.

dfcd35dd08 Whoops; we get an ACPI_OBJECT back from evaluating a method, not 
an ACPI_OPERAND_OBJECT.  Fix this so that the power resource type
can be properly checked, and we can get the system level and
resource order.

2b80a316c3 This was only half-implemented when I committed it, and certainly didn't 
work.  Now it's implemented and seems to work.

e71b638175 Update for new debug layer constant names in the ACPI CA 20010615 
import.

c5ba0be495 Sync to my work in progress: 
- Reorder the acpi_* functions in a sensible fashion
 - Add acpi_ForeachPackageObject and acpi_GetHandleInScope
 - Use the new debugging layer/level names
 - Implement most of the guts of the acpi_thermal module; passive cooling
   isn't there yet, but active cooling should work.
 - Implement power resource handling (acpi_powerres.c)

This compiles and mostly works, but my test coverage is small, so feedback
is welcome.
