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.
