This improves backwards +compatibility and also cleans up the code to a significant +degree. + +Add ASUS Value-add driver (Karol Kozimor and Julien Lerouge) + + + +---------------------------------------- +22 May 2003. Summary of changes for version 20030522: + +1) ACPI CA Core Subsystem: + +Found and fixed a reported problem where an AE_NOT_FOUND error +occurred occasionally during _BST evaluation. This turned out to +be an Owner ID allocation issue where a called method did not get +a new ID assigned to it. Eventually, (after 64k calls), the +Owner ID UINT16 would wraparound so that the ID would be the same +as the caller's and the called method would delete the caller's +namespace. + +Implemented extended error reporting for control methods that are +aborted due to a run-time exception. Output includes the exact +AML instruction that caused the method abort, a dump of the +method locals and arguments at the time of the abort, and a trace +of all nested control method calls. + +Modified the interpreter to allow the creation of buffers of zero +length from the AML code. Implemented new code to ensure that no +attempt is made to actually allocate a memory buffer (of length +zero) - instead, a simple buffer object with a NULL buffer +pointer and length zero is created. A warning is no longer +issued when the AML attempts to create a zero-length buffer. + +Implemented a workaround for the "leading asterisk issue" in +_HIDs, _UIDs, and _CIDs in the AML interpreter. One leading +asterisk is automatically removed if present in any HID, UID, or +CID strings. The iASL compiler will still flag this asterisk as +an error, however. + +Implemented full support for _CID methods that return a package +of multiple CIDs (Compatible IDs). The AcpiGetObjectInfo() +interface now additionally returns a device _CID list if present. +This required a change to the external interface in order to pass +an ACPI_BUFFER object as a parameter since the _CID list is of +variable length. + +Fixed a problem with the new AE_SAME_HANDLER exception where +handler initialization code did not know about this exception. + +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 (20030509): + Non-Debug Version: 73.4K Code, 9.7K Data, 83.1K Total + Debug Version: 156.1K Code, 63.9K Data, 220.0K Total + Current Release: + Non-Debug Version: 73.7K Code, 9.7K Data, 83.4K Total + Debug Version: 156.9K Code, 64.2K Data, 221.1K Total + + +2) Linux: + +Fixed a bug in which we would reinitialize the ACPI interrupt +after it was already working, thus disabling all ACPI and the +IRQs for any other device sharing the interrupt. (Thanks to Stian +Jordet) + +Toshiba driver update (John Belmonte) + +Return only 0 or 1 for our interrupt handler status (Andrew +Morton) + + +3) iASL Compiler: + +Fixed a reported problem where multiple (nested) ElseIf() +statements were not handled correctly by the compiler, resulting +in incorrect warnings and incorrect AML code. This was a problem +in both the ASL parser and the code generator. + + +4) Documentation: + +Added changes to existing interfaces, new exception codes, and +new text concerning reference count object management versus +garbage collection. + +---------------------------------------- +09 May 2003. Summary of changes for version 20030509. + + +1) ACPI CA Core Subsystem: + +Changed the subsystem initialization sequence to hold off +installation of address space handlers until the hardware has +been initialized and the system has entered ACPI mode. This is +because the installation of space handlers can cause _REG methods +to be run. Previously, the _REG methods could potentially be run +before ACPI mode was enabled. + +Fixed some memory leak issues related to address space handler +and notify handler installation. There were some problems with +the reference count mechanism caused by the fact that the handler +objects are shared across several namespace objects. + +Fixed a reported problem where reference counts within the +namespace were not properly updated when named objects created by +method execution were deleted. + +Fixed a reported problem where multiple SSDTs caused a deletion +issue during subsystem termination. Restructured the table data +structures to simplify the linked lists and the related code. + +Fixed a problem where the table ID associated with secondary +tables (SSDTs) was not being propagated into the namespace +objects created by those tables. This would only present a +problem for tables that are unloaded at run-time, however. + +Updated AcpiOsReadable and AcpiOsWritable to use the ACPI_SIZE +type as the length parameter (instead of UINT32). + +Solved a long-standing problem where an ALREADY_EXISTS error +appears on various systems. This problem could happen when there +are multiple PCI_Config operation regions under a single PCI root +bus. This doesn't happen very frequently, but there are some +systems that do this in the ASL. + +Fixed a reported problem where the internal DeleteNode function +was incorrectly handling the case where a namespace node was the +first in the parent's child list, and had additional peers (not +the only child, but first in the list of children.) + +Code and Data Size: Current 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: 73.7K Code, 9.5K Data, 83.2K Total + Debug Version: 156.1K Code, 63.6K Data, 219.7K Total + Current Release: + Non-Debug Version: 73.4K Code, 9.7K Data, 83.1K Total + Debug Version: 156.1K Code, 63.9K Data, 220.0K Total + + +2) Linux: + +Allow ":" in OS override string (Ducrot Bruno) + +Kobject fix (Greg KH) + + +3 iASL Compiler/Disassembler: + +Fixed a problem in the generation of the C source code files (AML +is emitted in C source statements for BIOS inclusion) where the +Ascii dump that appears within a C comment at the end of each +line could cause a compile time error if the AML sequence happens +to have an open comment or close comment sequence embedded. + + +---------------------------------------- +24 April 2003. Summary of changes for version 20030424. + + +1) ACPI CA Core Subsystem: + +Support for big-endian systems has been implemented. Most of the +support has been invisibly added behind big-endian versions of +the ACPI_MOVE_* macros. + +Fixed a problem in AcpiHwDisableGpeBlock() and +AcpiHwClearGpeBlock() where an incorrect offset was passed to the +low level hardware write routine. The offset parameter was +actually eliminated from the low level read/write routines +because they had become obsolete. + +Fixed a problem where a handler object was deleted twice during +the removal of a fixed event handler. + + +2) Linux: + +A fix for SMP systems with link devices was contributed by +Compaq's Dan Zink. + +(2.5) Return whether we handled the interrupt in our IRQ handler. +(Linux ISRs no longer return void, so we can propagate the +handler return value from the ACPI CA core back to the OS.) + + +3) Documentation: + +The ACPI CA Programmer Reference has been updated to reflect new +interfaces and changes to existing interfaces. + +---------------------------------------- +28 March 2003. Summary of changes for version 20030328. + +1) ACPI CA Core Subsystem: + +The GPE Block Device support has been completed. New interfaces +are AcpiInstallGpeBlock and AcpiRemoveGpeBlock. The Event +interfaces (enable, disable, clear, getstatus) have been split +into separate interfaces for Fixed Events and General Purpose +Events (GPEs) in order to support GPE Block Devices properly. + +Fixed a problem where the error message "Failed to acquire +semaphore" would appear during operations on the embedded +controller (EC). + +Code and Data Size: Current core subsystem library sizes are +shown below.
