ACPICA: create acpica/ directory

2009-01-09T08:30:47Z

also, delete sleep/ and delete ACPI_CFLAGS from Makefile Signed-off-by: Len Brown

ACPICA: delete acdisasm.h

2009-01-09T04:44:17Z

it is referenced only #ifdef ACPI_DISASSEMBLER, which is never set by the kernel. Signed-off-by: Len Brown

ACPICA: Restructure includes into public/private

2008-12-31T06:15:40Z

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 are to move all private headers to a new subdirectory.

ACPICA: Add support to externally execute _OSI method

2008-12-30T03:38:37Z

The current implemenation of _OSI within ACPICA only allows other control methods to execute _OSI. This change allows the host OS to execute _OSI via the AcpiEvaluateObject interface. _OSI is a special method -- it does not exist in the AML code, it is implemented within ACPICA.

ACPICA: Add a mechanism to escape infinite AML While() loops

2008-12-30T03:38:36Z

Add 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. Bob Moore, Alexey Starikovskiy. Signed-off-by: Bob Moore Signed-off-by: Lin Ming Signed-off-by: Len Brown

ACPICA: Optimize execution of AML While loops

2008-12-30T03:38:36Z

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%. Signed-off-by: Bob Moore Signed-off-by: Lin Ming Signed-off-by: Len Brown

ACPICA: Fix for implicit return compatibility

2008-10-23T03:14:49Z

Predicate can be used for an implicit return value. This change improves the implicit return mechanism to be more compatible with the MS interpreter. http://www.acpica.org/bugzilla/show_bug.cgi?id=349 Below AML code from http://bugzilla.kernel.org/show_bug.cgi?id=10686 Store(0x07D6, OSYS) Method (_CRT, 0, Serialized) { If (LLess (OSYS, 0x07D6)) { If (LEqual (\_SB.TJ85, Zero)) { Return (Add (0x0AAC, Multiply (TPC, 0x0A))) } Else { Return (Add (0x0AAC, Multiply (TP85, 0x0A))) } } } Previously _CRT returns 0x07D6, now it returns 0 (predicate value of LLess) Signed-off-by: Lin Ming Signed-off-by: Bob Moore Signed-off-by: Len Brown

ACPICA: Fixed a couple memory leaks associated with "implicit return"

2008-10-23T03:14:48Z

Fixed a couple memory leaks associated with "implicit return" objects when the AML Interpreter slack mode is enabled. http://www.acpica.org/bugzilla/show_bug.cgi?id=349 Signed-off-by: Lin Ming Signed-off-by: Bob Moore Signed-off-by: Len Brown

ACPICA: Cleanup for internal Reference Object

2008-10-23T03:14:45Z

Fix some sloppiness in the Reference object. No longer use AML opcodes to differentiate the types, introduce new reference Class. Cleanup the debug output code. Signed-off-by: Bob Moore Signed-off-by: Lin Ming Signed-off-by: Len Brown

ACPICA: Update for Reference ACPI_OPERAND_OBJECT

2008-10-23T03:14:44Z

1) Add new field for use by DdbHandle (Value) 2) Use ACPI_CAST_INDIRECT_PTR to eliminate strict type warnings 3) Cleanup debug output Signed-off-by: Bob Moore Signed-off-by: Lin Ming Signed-off-by: Len Brown
