27 May 2011. Summary of changes for version 20110527:
This release is available at www.acpica.org/downloads
1) ACPI CA Core Subsystem:
ASL Load() operator: Reinstate most restrictions on the incoming ACPI table
signature. Now, only allow SSDT, OEMx, and a null signature. History:
1) Originally, we checked the table signature for "SSDT" or "PSDT".
(PSDT is now obsolete.)
2) We added support for OEMx tables, signature "OEM" plus a fourth
"don't care" character.
3) Valid tables were encountered with a null signature, so we just
gave up on validating the signature, (05/2008).
4) We encountered non-AML tables such as the MADT, which caused
interpreter errors and kernel faults. So now, we once again allow
only SSDT, OEMx, and now, also a null signature. (05/2011).
Added the missing _TDL predefined name to the global name list in order to
enable validation. Affects both the core ACPICA code and the iASL compiler.
Example Code and Data Size: These are the sizes for the OS-independent
acpica.lib produced by the Microsoft Visual C++ 9.0 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 (VC 9.0):
Non-Debug Version: 90.0K Code, 23.8K Data, 113.8K Total
Debug Version: 164.5K Code, 68.0K Data, 232.5K Total
Current Release (VC 9.0):
Non-Debug Version: 90.1K Code, 23.9K Data, 114.0K Total
Debug Version: 165.6K Code, 68.4K Data, 234.0K Total
2) iASL Compiler/Disassembler and Tools:
Debugger/AcpiExec: Implemented support for "complex" method arguments on the
debugger command line. This adds support beyond simple integers -- including
Strings, Buffers, and Packages. Includes support for nested packages.
Increased the default command line buffer size to accommodate these arguments.
See the ACPICA reference for details and syntax. ACPICA BZ 917.
Debugger/AcpiExec: Implemented support for "default" method arguments for the
Execute/Debug command. Now, the debugger will always invoke a control method
with the required number of arguments -- even if the command line specifies
none or insufficient arguments. It uses default integer values for any missing
arguments. Also fixes a bug where only six method arguments maximum were
supported instead of the required seven.
Debugger/AcpiExec: Add a maximum buffer length parameter to AcpiOsGetLine and
also return status in order to prevent buffer overruns. See the ACPICA
reference for details and syntax. ACPICA BZ 921
iASL: Cleaned up support for Berkeley yacc. A general cleanup of code and
makefiles to simplify support for the two different but similar parser
generators, bison and yacc.
Updated the generic unix makefile for gcc 4. The default gcc version is now
expected to be 4 or greater, since options specific to gcc 4 are used.

13 April 2011. Summary of changes for version 20110413:
1) ACPI CA Core Subsystem:
Implemented support to execute a so-called "orphan" _REG method under the EC
device. This change will force the execution of a _REG method underneath the EC
device. This change will force the execution of a _REG method underneath the
EC
device even if there is no corresponding operation region of type
EmbeddedControl. Fixes a problem seen on some machines and apparently is
compatible with Windows behavior. ACPICA BZ 875.
Added more predefined methods that are eligible for automatic NULL package
element removal. This change adds another group of predefined names to the list
element removal. This change adds another group of predefined names to the
list
of names that can be repaired by having NULL package elements dynamically
removed. This group are those methods that return a single variable-length
package containing simple data types such as integers, buffers, strings. This
includes: _ALx, _BCL, _CID,_ DOD, _EDL, _FIX, _PCL, _PLD, _PMD, _PRx, _PSL, _Sx,
includes: _ALx, _BCL, _CID,_ DOD, _EDL, _FIX, _PCL, _PLD, _PMD, _PRx, _PSL,
_Sx,
and _TZD. ACPICA BZ 914.
