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 +address space. Includes support for bi-directional data buffers and an IPMI +address space handler (to be installed by an IPMI device driver.) ACPICA BZ +773. 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. +Changes 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 has +been added - utilities/utids.c. ACPICA BZ 368, 780. + +Updated the AcpiRead and AcpiWrite external interfaces to support 64-bit +transfers. The Value parameter has been extended from 32 bits to 64 bits in +order to support new ACPI 4.0 tables. These changes will require an update to +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 when +the host node was deleted. The data sub-object was not automatically deleted +when the host node was deleted. The interface to the handler had an unused +parameter, this was removed. ACPICA BZ 778. + +Enhanced the function that dumps ACPI table headers. All non-printable +characters in the string fields are now replaced with '?' (Signature, OemId, +OemTableId, and CompilerId.) ACPI tables with non-printable characters in +these fields are occasionally seen in the field. ACPICA BZ 788. + +Fixed a problem with predefined method repair code where the code that +attempts to repair/convert an object of incorrect type is only executed on +the first time the predefined method is called. The mechanism that disables +warnings 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 git +tree head. ACPICA BZ 776. + +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: 83.4K Code, 17.5K Data, 100.9K Total + Debug Version: 158.9K Code, 50.0K Data, 208.9K Total + Current Release: + Non-Debug Version: 84.7K Code, 17.8K Data, 102.5K Total + Debug Version: 160.5K Code, 50.6K Data, 211.1K Total + +2) iASL Compiler/Disassembler and Tools: + +ACPI 4.0: iASL and Disassembler - implemented support for the new IPMI +operation region keyword. ACPICA BZ 771, 772. Lin Ming. + +ACPI 4.0: iASL - implemented compile-time validation support for all new +predefined names and control methods (31 total).
