Summary of changes for version 20100702: +06 August 2010. Summary of changes for version 20100806: + +1) ACPI CA Core Subsystem: + +Designed and implemented a new host interface to the _OSI support code. This +will allow the host to dynamically add or remove multiple _OSI strings, as +well as install an optional handler that is called for each _OSI invocation. +Also added a new AML debugger command, 'osi' to display and modify the global +_OSI string table, and test support in the AcpiExec utility. See the ACPICA +reference manual for full details. Lin Ming, Bob Moore. ACPICA BZ 836. +New Functions: + AcpiInstallInterface - Add an _OSI string. + AcpiRemoveInterface - Delete an _OSI string. + AcpiInstallInterfaceHandler - Install optional _OSI handler. +Obsolete Functions: + AcpiOsValidateInterface - no longer used. +New Files: + source/components/utilities/utosi.c + +Re-introduced the support to enable multi-byte transfers for Embedded +Controller (EC) operation regions. A reported problem was found to be a bug +in the host OS, not in the multi-byte support. Previously, the maximum data +size passed to the EC operation region handler was a single byte. There are +often EC Fields larger than one byte that need to be transferred, and it is +useful for the EC driver to lock these as a single transaction. This change +enables single transfers larger than 8 bits. This effectively changes the +access to the EC space from ByteAcc to AnyAcc, and will probably require +changes to the host OS Embedded Controller driver to enable 16/32/64/256-bit +transfers in addition to 8-bit transfers. Alexey Starikovskiy, Lin Ming. + +Fixed a problem with the prototype for AcpiOsReadPciConfiguration. The +prototype in acpiosxf.h had the output value pointer as a (void *). +It should be a (UINT64 *). This may affect some host OSL code. + +Fixed a couple problems with the recently modified Linux makefiles for iASL +and AcpiExec. These new makefiles place the generated object files in the +local directory so that there can be no collisions between the files that are +shared between them that are compiled with different options. + +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: 88.3K Code, 18.8K Data, 107.1K Total + Debug Version: 164.0K Code, 51.5K Data, 215.5K Total + Current Release: + Non-Debug Version: 89.1K Code, 19.0K Data, 108.1K Total + Debug Version: 165.1K Code, 51.9K Data, 217.0K Total -This release is available at www.acpica.org/downloads +2) iASL Compiler/Disassembler and Tools: + +iASL/Disassembler: Added a new option (-da, "disassemble all") to load the +namespace from and disassemble an entire group of AML files. Useful for +loading all of the AML tables for a given machine (DSDT, SSDT1...SSDTn) and +disassembling with one simple command. ACPICA BZ 865. Lin Ming. + +iASL: Allow multiple invocations of -e option. This change allows multiple +uses of -e on the command line: "-e ssdt1.dat -e ssdt2.dat".
