03 September 2009. Summary of changes for version 20090903:
This release is available at www.acpica.org/downloads
1) ACPI CA Core Subsystem:
For Windows Vista compatibility, added the automatic execution of an _INI m=
ethod located at the namespace root (\_INI). This method is executed at tab=
le load time. This support is in addition to the automatic execution of \_S=
B._INI. Lin Ming.
Fixed a possible memory leak in the interpreter for AML package objects if =
the package initializer list is longer than the defined size of the package=
. This apparently can only happen if the BIOS changes the package size on t=
he fly (seen in a _PSS object), as ASL compilers do not allow this. The int=
erpreter will truncate the package to the defined size (and issue an error =
message), but previously could leave the extra objects undeleted if they we=
re pre-created during the argument processing (such is the case if the pack=
age consists of a number of sub-packages as in the _PSS.) ACPICA BZ 805.
Fixed a problem seen when a Buffer or String is stored to itself via ASL. T=
his has been reported in the field. Previously, ACPICA would zero out the b=
uffer/string. Now, the operation is treated as a noop. Provides Windows com=
patibility. ACPICA BZ 803. Lin Ming.
Removed an extraneous error message for ASL constructs of the form Store(Lo=
calX,LocalX) when LocalX is uninitialized. These curious statements are see=
n in many BIOSs and are once again treated as NOOPs and no error is emitted=
when they are encountered. ACPICA BZ 785.
Fixed an extraneous warning message if a _DSM reserved method returns a Pac=
kage object. _DSM can return any type of object, so validation on the retur=
n type cannot be performed. ACPICA BZ 802.
Example Code and Data Size: These are the sizes for the OS-independent acpi=
ca.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 muc=
h larger code and data size.
Previous Release:
Non-Debug Version: 85.5K Code, 18.0K Data, 103.5K Total
Debug Version: 161.6K Code, 50.9K Data, 212.5K Total
Current Release:
Non-Debug Version: 85.6K Code, 18.0K Data, 103.6K Total
Debug Version: 161.7K Code, 50.9K Data, 212.6K Total
2) iASL Compiler/Disassembler and Tools:
iASL: Fixed a problem with the use of the Alias operator and Resource Templ=
ates. The correct alias is now constructed and no error is emitted. ACPICA =
BZ 738.
iASL: Implemented the -I option to specify additional search directories fo=
r include files. Allows multiple additional search paths for include files.=
Directories are searched in the order specified on the command line (after=
the local directory is searched.) ACPICA BZ 800.
iASL: Fixed a problem where the full pathname for include files was not emi=
tted for warnings/errors. This caused the IDE support to not work properly.=
ACPICA BZ 765.
iASL: Implemented the -@ option to specify a Windows-style response file co=
ntaining additional command line options. ACPICA BZ 801.
AcpiExec: Added support to load multiple AML files simultaneously (such as =
a DSDT and multiple SSDTs). Also added support for wildcards within the AML=
pathname. These features allow all machine tables to be easily loaded and =
debugged together. ACPICA BZ 804.
Disassembler: Added missing support for disassembly of HEST table Error Ban=
k subtables.=20
