14 December 2009. Summary of changes for version 20091214:
This release is available at www.acpica.org/downloads
1) ACPI CA Core Subsystem:
Enhanced automatic data type conversions for predefined name repairs. This
change expands the automatic repairs/conversions for predefined name return
values to make Integers, Strings, and Buffers fully interchangeable. Also, a
Buffer can be converted to a Package of Integers if necessary. The nsrepair.c
module was completely restructured. Lin Ming, Bob Moore.
Implemented automatic removal of null package elements during predefined name
repairs. This change will automatically remove embedded and trailing NULL
package elements from returned package objects that are defined to contain a
variable number of sub-packages. The driver is then presented with a package
with no null elements to deal with. ACPICA BZ 819.
Implemented a repair for the predefined _FDE and _GTM names. The expected
return value for both names is a Buffer of 5 DWORDs. This repair fixes two
possible problems (both seen in the field), where a package of integers is
returned, or a buffer of BYTEs is returned. With assistance from Jung-uk Kim.
Implemented additional module-level code support. This change will properly
execute module-level code that is not at the root of the namespace (under a
Device object, etc.). Now executes the code within the current scope instead
of the root. ACPICA BZ 762. Lin Ming.
Fixed possible mutex acquisition errors when running _REG methods. Fixes a
problem where mutex errors can occur when running a _REG method that is in
the same scope as a method-defined operation region or an operation region
under a module-level IF block. This type of code is rare, so the problem has
not been seen before. ACPICA BZ 826. Lin Ming, Bob Moore.
Fixed a possible memory leak during module-level code execution. An object
could be leaked for each block of executed module-level code if the
interpreter slack mode is enabled This change deletes any implicitly returned
object from the module-level code block. Lin Ming.
Removed messages for successful predefined repair(s). The repair mechanism
was considered too wordy. Now, messages are only unconditionally emitted if
the return object cannot be repaired. Existing messages for successful
repairs were converted to ACPI_DEBUG_PRINT messages for now. ACPICA BZ 827.
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.
Previous Release:
Non-Debug Version: 86.6K Code, 18.2K Data, 104.8K Total
Debug Version: 162.7K Code, 50.8K Data, 213.5K Total
Current Release:
Non-Debug Version: 87.0K Code, 18.0K Data, 105.0K Total
Debug Version: 163.4K Code, 50.8K Data, 214.2K Total
2) iASL Compiler/Disassembler and Tools:
iASL: Fixed a regression introduced in 20091112 where intermediate .SRC files
were no longer automatically removed at the termination of the compile.
acpiexec: Implemented the -f option to specify default region fill value.
This option specifies the value used to initialize buffers that simulate
operation regions. Default value is zero. Useful for debugging problems that
depend on a specific initial value for a region or field.
