Summary of changes for version 20121114: +17 January 2013. Summary of changes for version 20130117: + + +1) ACPICA Kernel-resident Subsystem: + +Updated the AcpiGetSleepTypeData interface: Allow the \_Sx methods to +return either 1 or 2 integers. Although the ACPI spec defines the \_Sx +objects to return a package containing one integer, most BIOS code returns +two integers and the previous code reflects that. However, we also need to +support BIOS code that actually implements to the ACPI spec, and this +change reflects this. + +Fixed two issues with the ACPI_DEBUG_PRINT macros: +1) Added the ACPI_DO_WHILE macro to the main DEBUG_PRINT helper macro for +C compilers that require this support. +2) Renamed the internal ACPI_DEBUG macro to ACPI_DO_DEBUG_PRINT since +ACPI_DEBUG is already used by many of the various hosts. + +Updated all ACPICA copyrights and signons to 2013. Added the 2013 +copyright to all module headers and signons, including the standard Linux +header. This affects virtually every file in the ACPICA core subsystem, +iASL compiler, all ACPICA utilities, and the test suites. -This release is available at https://www.acpica.org/downloads -The ACPI 5.0 specification is available at www.acpi.info +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: + Non-Debug Version: 94.5K Code, 25.5K Data, 120.0K Total + Debug Version: 182.2K Code, 74.9K Data, 257.1K Total + Current Release: + Non-Debug Version: 94.5K Code, 25.4K Data, 119.9K Total + Debug Version: 182.3K Code, 75.0K Data, 257.3K Total + + +2) iASL Compiler/Disassembler and Tools: + +Generic Unix OSL: Use a buffer to eliminate multiple vfprintf()s and +prevent a possible fault on some hosts. Some C libraries modify the arg +pointer parameter to vfprintf making it difficult to call it twice in the +AcpiOsVprintf function. Use a local buffer to workaround this issue. This +does not affect the Windows OSL since the Win C library does not modify +the arg pointer. Chao Guan, Bob Moore. + +iASL: Fixed a possible infinite loop when the maximum error count is +reached. If an output file other than the .AML file is specified (such as +a listing file), and the maximum number of errors is reached, do not +attempt to flush data to the output file(s) as the compiler is aborting. +This can cause an infinite loop as the max error count code essentially +keeps calling itself. + +iASL/Disassembler: Added an option (-in) to ignore NOOP opcodes/operators. +Implemented for both the compiler and the disassembler. Often, the NOOP +opcode is used as padding for packages that are changed dynamically by the +BIOS. When disassembled and recompiled, these NOOPs will cause syntax +errors. This option causes the disassembler to ignore all NOOP opcodes +(0xA3), and it also causes the compiler to ignore all ASL source code NOOP +statements as well. + +Debugger: Enhanced the Sleep command to execute all sleep states. This +change allows Sleep to be invoked with no arguments and causes the +debugger to execute all of the sleep states, 0-5, automatically. + +---------------------------------------- +20 December 2012. Summary of changes for version 20121220: + +1) ACPICA Kernel-resident Subsystem: + +Implemented a new interface, AcpiWalkResourceBuffer. This interface is an +alternate entry point for AcpiWalkResources and improves the usability of +the resource manager by accepting as input a buffer containing the output +of either a _CRS, _PRS, or _AEI method. The key functionality is that the +input buffer is not deleted by this interface so that it can be used by +the host later. See the ACPICA reference for details. + +Interpreter: Add a warning if a 64-bit constant appears in a 32-bit table +(DSDT version < 2). The constant will be truncated and this warning +reflects that behavior. + +Resource Manager: Add support for the new ACPI 5.0 wake bit in the IRQ, +ExtendedInterrupt, and GpioInt descriptors. This change adds support to +both get and set the new wake bit in these descriptors, separately from +the existing share bit. Reported by Aaron Lu. + +Interpreter: Fix Store() when an implicit conversion is not possible. For +example, in the cases such as a store of a string to an existing package +object, implement the store as a CopyObject(). This is a small departure +from the ACPI specification which states that the control method should be +aborted in this case. However, the ASLTS suite depends on this behavior. + +Performance improvement for the various FUNCTION_TRACE and DEBUG_PRINT +macros: check if debug output is currently enabled as soon as possible to +minimize performance impact if debug is in fact not enabled. + +Source code restructuring: Cleanup to improve modularity. The following +new files have been added: dbconvert.c, evhandler.c, nsprepkg.c, +psopinfo.c, psobject.c, rsdumpinfo.c, utstring.c, and utownerid.c. +Associated makefiles and project files have been updated. + +Changed an exception code for LoadTable operator. For the case where one +of the input strings is too long, change the returned exception code from +AE_BAD_PARAMETER to AE_AML_STRING_LIMIT. + +Fixed a possible memory leak in dispatcher error path. On error, delete +the mutex object created during method mutex creation. Reported by +tim.gardner@canonical.com. + +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: + Non-Debug Version: 94.3K Code, 25.3K Data, 119.6K Total + Debug Version: 175.5K Code, 74.5K Data, 250.0K Total + Current Release: + Non-Debug Version: 94.5K Code, 25.5K Data, 120.0K Total + Debug Version: 182.2K Code, 74.9K Data, 257.1K Total + + +2) iASL Compiler/Disassembler and Tools: + +iASL: Disallow a method call as argument to the ObjectType ASL operator. +This change tracks an errata to the ACPI 5.0 document. The AML grammar +will not allow the interpreter to differentiate between a method and a +method invocation when these are used as an argument to the ObjectType +operator. The ACPI specification change is to disallow a method invocation +(UserTerm) for the ObjectType operator. + +Finish support for the TPM2 and CSRT tables in the headers, table +compiler, and disassembler. + +Unix user-space OSL: Fix a problem with WaitSemaphore where the timeout +always expires immediately if the semaphore is not available. The original +code was using a relative-time timeout, but sem_timedwait requires the use +of an absolute time. + +iASL: Added a remark if the Timer() operator is used within a 32-bit +table. This operator returns a 64-bit time value that will be truncated +within a 32-bit table. + +iASL Source code restructuring: Cleanup to improve modularity. The +following new files have been added: aslhex.c, aslxref.c, aslnamesp.c, +aslmethod.c, and aslfileio.c. Associated makefiles and project files have +been updated. + + +---------------------------------------- +14 November 2012.
