Summary of changes for version 20160729: + +This release is available at https://acpica.org/downloads + + +1) ACPICA kernel-resident subsystem: + +Implemented basic UEFI support for the various ACPICA tools. This +includes: +1) An OSL to implement the various AcpiOs* interfaces on UEFI. +2) Support to obtain the ACPI tables on UEFI. +3) Local implementation of required C library functions not available on +UEFI. +4) A front-end (main) function for the tools for UEFI-related +initialization. + +The initial deployment of this support is the AcpiDump utility executing +as an UEFI application via EDK2 (EDKII, "UEFI Firmware Development Kit"). +Current environments supported are Linux/Unix. MSVC generation is not +supported at this time. See the generate/efi/README file for build +instructions. Lv Zheng. + +Future plans include porting the AcpiExec utility to execute natively on +the platform with I/O and memory access. This will allow viewing/dump of +the platform namespace and native execution of ACPI control methods that +access the actual hardware. To fully implement this support, the OSL +functions below must be implemented with UEFI interfaces. Any community +help in the implementation of these functions would be appreciated: + AcpiOsReadPort + AcpiOsWritePort + AcpiOsReadMemory + AcpiOsWriteMemory + AcpiOsReadPciConfiguration + AcpiOsWritePciConfiguration + + +Restructured and standardized the C library configuration for ACPICA, +resulting in the various configuration options below. This includes a +global restructuring of the compiler-dependent and platform-dependent +include files. These changes may affect the existing platform-dependent +configuration files on some hosts. Lv Zheng. + +The current C library configuration options appear below. For any issues, +it may be helpful to examine the existing compiler-dependent and +platform-dependent files as examples. Lv Zheng. + +1) Linux kernel: + ACPI_USE_STANDARD_HEADERS=n in order not to use system-provided C +library. + ACPI_USE_SYSTEM_CLIBRARY=y in order not to use ACPICA mini C library. +2) Unix/Windows/BSD applications: + ACPI_USE_STANDARD_HEADERS=y in order to use system-provided C +library. + ACPI_USE_SYSTEM_CLIBRARY=y in order not to use ACPICA mini C library. +3) UEFI applications: + ACPI_USE_STANDARD_HEADERS=n in order not to use system-provided C +library. + ACPI_USE_SYSTEM_CLIBRARY=n in order to use ACPICA mini C library. +4) UEFI applications (EDK2/StdLib): + ACPI_USE_STANDARD_HEADERS=y in order to use EDK2 StdLib C library. + ACPI_USE_SYSTEM_CLIBRARY=y in order to use EDK2 StdLib C library. + + +AML interpreter: "module-level code" support. Allows for execution of so- +called "executable" AML code (math/logical operations, etc.) outside of +control methods not just at the module level (top level) but also within +any scope declared outside of a control method - Scope{}, Device{}, +Processor{}, PowerResource{}, and ThermalZone{}. Lv Zheng. + +Simplified the configuration of the "maximum AML loops" global option by +adding a global public variable, "AcpiGbl_MaxLoopIterations" which can be +modified at runtime. + + +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. + + Current Release: + Non-Debug Version: 139.1K Code, 22.9K Data, 162.0K Total + Debug Version: 199.0K Code, 81.8K Data, 280.8K Total + + +2) iASL Compiler/Disassembler and Tools: + +iASL: Add full support for the RASF ACPI table (RAS Features Table). +Includes disassembler, data table compiler, and header support. + +iASL Expand "module-level code" support. Allows for +compilation/disassembly of so-called "executable" AML code (math/logical +operations, etc.) outside of control methods not just at the module level +(top level) but also within any scope declared outside of a control +method - Scope{}, Device{}, Processor{}, PowerResource{}, and +ThermalZone{}. + +AcpiDump: Added support for dumping all SSDTs on newer versions of +Windows. These tables are now easily available -- SSDTs are not available +through the registry on older versions. + +---------------------------------------- 27 May 2016.
