Summary of changes for version 20040402: + +1) ACPI CA Core Subsystem: + +Fixed an interpreter problem where an indirect store through an +ArgX parameter was incorrectly applying the "implicit conversion +rules" during the store. From the ACPI specification: "If the +target is a method local or argument (LocalX or ArgX), no +conversion is performed and the result is stored directly to the +target". The new behavior is to disable implicit conversion +during ALL stores to an ArgX. + +Changed the behavior of the _PRW method scan to ignore any and +all errors returned by a given _PRW. This prevents the scan from +aborting from the failure of any single _PRW. + +Moved the runtime configuration parameters from the global init +procedure to static variables in acglobal.h. This will allow the +host to override the default values easily. + +Code and Data Size: Current and previous core subsystem library +sizes are shown below. These are the code and data sizes for the +acpica.lib produced by the Microsoft Visual C++ 6.0 compiler, and +these values do not include any ACPI driver or OSPM code. The +debug version of the code includes the debug output trace +mechanism and has a much larger code and data size. Note that +these values will vary depending on the efficiency of the +compiler and the compiler options used during generation. + + Previous Release: + Non-Debug Version: 76.9K Code, 11.4K Data, 88.3K Total + Debug Version: 160.8K Code, 66.1K Data, 226.9K Total + Current Release: + Non-Debug Version: 77.0K Code, 11.4K Data, 88.4K Total + Debug Version: 161.0K Code, 66.3K Data, 227.3K Total + + +2) iASL Compiler/Disassembler: + +iASL now fully disassembles SSDTs. However, External() +statements are not generated automatically for unresolved symbols +at this time. This is a planned feature for future +implementation. + +Fixed a scoping problem in the disassembler that occurs when the +type of the target of a Scope() operator is overridden. This +problem caused an incorrectly nested internal namespace to be +constructed. + +Any warnings or errors that are emitted during disassembly are +now commented out automatically so that the resulting file can be +recompiled without any hand editing. + +---------------------------------------- +26 March 2004. Summary of changes for version 20040326: + +1) ACPI CA Core Subsystem: + +Implemented support for "wake" GPEs via interaction between GPEs +and the _PRW methods. Every GPE that is pointed to by one or +more _PRWs is identified as a WAKE GPE and by default will no +longer be enabled at runtime. Previously, we were blindly +enabling all GPEs with a corresponding _Lxx or _Exx method - but +most of these turn out to be WAKE GPEs anyway. We believe this +has been the cause of thousands of "spurious" GPEs on some +systems. + +This new GPE behavior is can be reverted to the original behavior +(enable ALL GPEs at runtime) via a runtime flag. + +Fixed a problem where aliased control methods could not access +objects properly. The proper scope within the namespace was not +initialized (transferred to the target of the aliased method) +before executing the target method. + +Fixed a potential race condition on internal object deletion on +the return object in AcpiEvaluateObject. + +Integrated a fix for resource descriptors where both _MEM and +_MTP were being extracted instead of just _MEM. (i.e. bitmask +was incorrectly too wide, 0x0F instead of 0x03.) + +Added a special case for ACPI_ROOT_OBJECT in AcpiUtGetNodeName, +preventing a fault in some cases. + +Updated Notify() values for debug statements in evmisc.c + +Return proper status from AcpiUtMutexInitialize, not just simply +AE_OK. + +Code and Data Size: Current and previous core subsystem library +sizes are shown below. These are the code and data sizes for the +acpica.lib produced by the Microsoft Visual C++ 6.0 compiler, and +these values do not include any ACPI driver or OSPM code. The +debug version of the code includes the debug output trace +mechanism and has a much larger code and data size. Note that +these values will vary depending on the efficiency of the +compiler and the compiler options used during generation. + + Previous Release: + Non-Debug Version: 76.5K Code, 11.3K Data, 87.8K Total + Debug Version: 160.3K Code, 66.0K Data, 226.3K Total + Current Release: + Non-Debug Version: 76.9K Code, 11.4K Data, 88.3K Total + Debug Version: 160.8K Code, 66.1K Data, 226.9K Total + +---------------------------------------- 11 March 2004.
