25 June 2009. Summary of changes for version 20090625:
This release is available at www.acpica.org/downloads
The ACPI 4.0 Specification was released on June 16 and is available at www.=
acpi.info. ACPICA implementation of ACPI 4.0 is underway and will continue =
for the next few releases.
1) ACPI CA Core Subsystem:
ACPI 4.0: Implemented interpreter support for the IPMI operation region add=
ress space. Includes support for bi-directional data buffers and an IPMI ad=
dress space handler (to be installed by an IPMI device driver.) ACPICA BZ 7=
73. Lin Ming.
ACPI 4.0: Added changes for existing ACPI tables - FACS and SRAT. Includes =
support in both the header files and the disassembler.
Completed a major update for the AcpiGetObjectInfo external interface. Chan=
ges include:
- Support for variable, unlimited length HID, UID, and CID strings.
- Support Processor objects the same as Devices (HID,UID,CID,ADR,STA, etc.=
)
- Call the _SxW power methods on behalf of a device object.
- Determine if a device is a PCI root bridge.
- Change the ACPI_BUFFER parameter to ACPI_DEVICE_INFO.
These changes will require an update to all callers of this interface. See =
the updated ACPICA Programmer Reference for details. One new source file ha=
s been added - utilities/utids.c. ACPICA BZ 368, 780.
Updated the AcpiRead and AcpiWrite external interfaces to support 64-bit tr=
ansfers. The Value parameter has been extended from 32 bits to 64 bits in o=
rder to support new ACPI 4.0 tables. These changes will require an update t=
o all callers of these interfaces. See the ACPICA Programmer Reference for =
details. ACPICA BZ 768.
Fixed several problems with AcpiAttachData. The handler was not invoked whe=
n the host node was deleted. The data sub-object was not automatically dele=
ted when the host node was deleted. The interface to the handler had an unu=
sed parameter, this was removed. ACPICA BZ 778.
Enhanced the function that dumps ACPI table headers. All non-printable char=
acters in the string fields are now replaced with '?' (Signature, OemId, Oe=
mTableId, and CompilerId.) ACPI tables with non-printable characters in the=
se fields are occasionally seen in the field. ACPICA BZ 788.
Fixed a problem with predefined method repair code where the code that atte=
mpts to repair/convert an object of incorrect type is only executed on the =
first time the predefined method is called. The mechanism that disables war=
nings on subsequent calls was interfering with the repair mechanism. ACPICA=
BZ 781.
Fixed a possible memory leak in the predefined validation/repair code when =
a buffer is automatically converted to an expected string object.
Removed obsolete 16-bit files from the distribution and from the current gi=
t tree head. ACPICA BZ 776.
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.

2) iASL Compiler/Disassembler and Tools:
ACPI 4.0: iASL and Disassembler - implemented support for the new IPMI oper=
ation region keyword. ACPICA BZ 771, 772. Lin Ming.
ACPI 4.0: iASL - implemented compile-time validation support for all new pr=
edefined names and control methods (31 total). ACPICA BZ 769.
