Summary of changes for version 20030228. + + +1) ACPI CA Core Subsystem: + +The GPE handling and dispatch code has been completely overhauled +in preparation for support of GPE Block Devices (ID ACPI0006). +This affects internal data structures and code only; there should +be no differences visible externally. One new file has been +added, evgpeblk.c + +The FADT fields GPE0_BLK_LEN and GPE1_BLK_LEN are now the only +fields that are used to determine the GPE block lengths. The +REGISTER_BIT_WIDTH field of the X_GPEx_BLK extended address +structures are ignored. This is per the ACPI specification but +it isn't very clear. The full 256 Block 0/1 GPEs are now +supported (the use of REGISTER_BIT_WIDTH limited the number of +GPEs to 128). + +In the SCI interrupt handler, removed the read of the PM1_CONTROL +register to look at the SCI_EN bit. On some machines, this read +causes an SMI event and greatly slows down SCI events. (This may +in fact be the cause of slow battery status response on some +systems.) + +Fixed a problem where a store of a NULL string to a package +object could cause the premature deletion of the object. This +was seen during execution of the battery _BIF method on some +systems, resulting in no battery data being returned. + +Added AcpiWalkResources interface to simplify parsing of resource +lists. + +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: 72.0K Code, 9.5K Data, 81.5K Total + Debug Version: 153.0K Code, 62.9K Data, 215.9K Total + Current Release: + Non-Debug Version: 72.3K Code, 9.5K Data, 81.8K Total + Debug Version: 154.0K Code, 63.4K Data, 217.4K Total + + +2) Linux + +S3 fixes (Ole Rohne) + +Update ACPI PHP driver with to use new acpi_walk_resource API +(Bjorn Helgaas) + +Add S4BIOS support (Pavel Machek) + +Map in entire table before performing checksum (John Stultz) + +Expand the mem= cmdline to allow the specification of reserved +and ACPI DATA blocks (Pavel Machek) + +Never use ACPI on VISWS + +Fix derive_pci_id (Ducrot Bruno, Alvaro Lopez) + +Revert a change that allowed P_BLK lengths to be 4 or 5.

Summary of changes for version 20030122. + + +1) ACPI CA Core Subsystem: + +Added a check for constructs of the form: Store (Local0, Local0) +where Local0 is not initialized. Apparently, some BIOS +programmers believe that this is a NOOP. Since this store +doesn't do anything anyway, the new prototype behavior will +ignore this error. This is a case where we can relax the strict +checking in the interpreter in the name of compatibility. + + +2) Linux + +The AcpiSrc Source Conversion Utility has been released with the +Linux package for the first time. This is the utility that is +used to convert the ACPI CA base source code to the Linux +version. + +(Both) Handle P_BLK lengths shorter than 6 more gracefully + +(Both) Move more headers to include/acpi, and delete an unused +header. + +(Both) Move drivers/acpi/include directory to include/acpi + +(Both) Boot functions don't use cmdline, so don't pass it around + +(Both) Remove include of unused header (Adrian Bunk) + +(Both) acpiphp.h includes both linux/acpi.h and acpi_bus.h.

Summary of changes for version 20030109. + +1) ACPI CA Core Subsystem: + +Changed the behavior of the internal Buffer-to-String conversion +function. The current ACPI specification states that the +contents of the buffer are "converted to a string of two- +character hexadecimal numbers, each separated by a space". +Unfortunately, this definition is not backwards compatible with +existing ACPI 1.0 implementations (although the behavior was not +defined in the ACPI 1.0 specification). The new behavior simply +copies data from the buffer to the string until a null character +is found or the end of the buffer is reached. The new String +object is always null terminated. This problem was seen during +the generation of _BIF battery data where incorrect strings were +returned for battery type, etc. This will also require an errata +to the ACPI specification. + +Renamed all instances of NATIVE_UINT and NATIVE_INT to +ACPI_NATIVE_UINT and ACPI_NATIVE_INT, respectively. + +Copyright in all module headers (both Linux and non-Linux) has be +updated to 2003. + +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: 72.0K Code, 9.5K Data, 81.5K Total + Debug Version: 153.0K Code, 62.9K Data, 215.9K Total + Current Release: + Non-Debug Version: 72.0K Code, 9.5K Data, 81.5K Total + Debug Version: 153.0K Code, 62.9K Data, 215.9K Total + + +2) Linux + +Fixed an oops on module insertion/removal (Matthew Tippett) + +(2.4) Fix to handle dynamic size of mp_irqs (Joerg Prante) + +(2.5) Replace pr_debug (Randy Dunlap) + +(2.5) Remove usage of CPUFREQ_ALL_CPUS (Dominik Brodowski) + +(Both) Eliminate spawning of thread from timer callback, in favor +of schedule_work() + +(Both) Show Lid status in /proc (Zdenek OGAR Skalak) + +(Both) Added define for Fixed Function HW region (Matthew Wilcox) + +(Both) Add missing statics to button.c (Pavel Machek) + +Several changes have been made to the source code translation +utility that generates the Linux Code in order to make the code +more "Linux-like": + +All typedefs on structs and unions have been removed in keeping +with the Linux coding style. + +Removed the non-Linux SourceSafe module revision number from each +module header. + +Completed major overhaul of symbols to be lowercased for linux. +Doubled the number of symbols that are lowercased. + +Fixed a problem where identifiers within procedure headers and +within quotes were not fully lower cased (they were left with a +starting capital.) + +Some C macros whose only purpose is to allow the generation of 16- +bit code are now completely removed in the Linux code, increasing +readability and maintainability. + +---------------------------------------- + +12 December 2002. Summary of changes for version 20021212. + + +1) ACPI CA Core Subsystem: + +Fixed a problem where the creation of a zero-length AML Buffer +would cause a fault. + +Fixed a problem where a Buffer object that pointed to a static +AML buffer (in an ACPI table) could inadvertently be deleted, +causing memory corruption. + +Fixed a problem where a user buffer (passed in to the external +ACPI CA interfaces) could be overwritten if the buffer was too +small to complete the operation, causing memory corruption. + +Fixed a problem in the Buffer-to-String conversion code where a +string of length one was always returned, regardless of the size +of the input Buffer object. + +Removed the NATIVE_CHAR data type across the entire source due to +lack of need and lack of consistent use. + +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: 72.1K Code, 9.5K Data, 81.6K Total + Debug Version: 152.7K Code, 62.7K Data, 215.4K Total + Current Release: + Non-Debug Version: 72.0K Code, 9.5K Data, 81.5K Total + Debug Version: 153.0K Code, 62.9K Data, 215.9K Total + + +---------------------------------------- +05 December 2002. Summary of changes for version 20021205. + +1) ACPI CA Core Subsystem: + +Fixed a problem where a store to a String or Buffer object could +cause corruption of the DSDT if the object type being stored was +the same as the target object type and the length of the object +being stored was equal to or smaller than the original (existing) +target object. This was seen to cause corruption of battery _BIF +buffers if the _BIF method modified the buffer on the fly. + +Fixed a problem where an internal error was generated if a +control method invocation was used in an OperationRegion, Buffer, +or Package declaration. This was caused by the deferred parsing +of the control method and thus the deferred creation of the +internal method object. The solution to this problem was to +create the internal method object at the moment the method is +encountered in the first pass - so that subsequent references to +the method will able to obtain the required parameter count and +thus properly parse the method invocation. This problem +presented itself as an AE_AML_INTERNAL during the pass 1 parse +phase during table load. + +Fixed a problem where the internal String object copy routine did +not always allocate sufficient memory for the target String +object and caused memory corruption. This problem was seen to +cause "Allocation already present in list!" errors as memory +allocation became corrupted. + +Implemented a new function for the evaluation of namespace +objects that allows the specification of the allowable return +object types. This simplifies a lot of code that checks for a +return object of one or more specific objects returned from the +evaluation (such as _STA, etc.) This may become and external +function if it would be useful to ACPI-related drivers. + +Completed another round of prefixing #defines with "ACPI_" for +clarity. + +Completed additional code restructuring to allow more modular +linking for iASL compiler and AcpiExec. Several files were split +creating new files. New files: nsparse.c dsinit.c evgpe.c + +Implemented an abort mechanism to terminate an executing control +method via the AML debugger. This feature is useful for +debugging control methods that depend (wait) for specific +hardware responses. + +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: 71.4K Code, 9.0K Data, 80.4K Total + Debug Version: 152.9K Code, 63.3K Data, 216.2K Total + Current Release: + Non-Debug Version: 72.1K Code, 9.5K Data, 81.6K Total + Debug Version: 152.7K Code, 62.7K Data, 215.4K Total + + +2) iASL Compiler/Disassembler + +Fixed a compiler code generation problem for "Interrupt" Resource +Descriptors. If specified in the ASL, the optional "Resource +Source Index" and "Resource Source" fields were not inserted into +the correct location within the AML resource descriptor, creating +an invalid descriptor. + +Fixed a disassembler problem for "Interrupt" resource +descriptors. The optional "Resource Source Index" and "Resource +Source" fields were ignored. + + +---------------------------------------- +22 November 2002. Summary of changes for version 20021122. + + +1) ACPI CA Core Subsystem: + +Fixed a reported problem where an object stored to a Method Local +or Arg was not copied to a new object during the store - the +object pointer was simply copied to the Local/Arg. This caused +all subsequent operations on the Local/Arg to also affect the +original source of the store operation. + +Fixed a problem where a store operation to a Method Local or Arg +was not completed properly if the Local/Arg contained a reference +(from RefOf) to a named field. The general-purpose store-to- +namespace-node code is now used so that this case is handled +automatically. + +Fixed a problem where the internal object copy routine would +cause a protection fault if the object being copied was a Package +and contained either 1) a NULL package element or 2) a nested sub- +package. + +Fixed a problem with the GPE initialization that resulted from an +ambiguity in the ACPI specification. One section of the +specification states that both the address and length of the GPE +block must be zero if the block is not supported. Another +section implies that only the address need be zero if the block +is not supported. The code has been changed so that both the +address and the length must be non-zero to indicate a valid GPE +block (i.e., if either the address or the length is zero, the GPE +block is invalid.) + +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: 71.3K Code, 9.0K Data, 80.3K Total + Debug Version: 152.7K Code, 63.2K Data, 215.5K Total + Current Release: + Non-Debug Version: 71.4K Code, 9.0K Data, 80.4K Total + Debug Version: 152.9K Code, 63.3K Data, 216.2K Total + + +2) Linux + +Cleaned up EC driver. Exported an external EC read/write +interface. By going through this, other drivers (most notably +sonypi) will be able to serialize access to the EC. + + +3) iASL Compiler/Disassembler + +Implemented support to optionally generate include files for both +ASM and C (the -i switch). This simplifies BIOS development by +automatically creating include files that contain external +declarations for the symbols that are created within the +(optionally generated) ASM and C AML source files. + + +---------------------------------------- +15 November 2002. Summary of changes for version 20021115. + +1) ACPI CA Core Subsystem: + +Fixed a memory leak problem where an error during resolution of +method arguments during a method invocation from another method +failed to cleanup properly by deleting all successfully resolved +argument objects. + +Fixed a problem where the target of the Index() operator was not +correctly constructed if the source object was a package. This +problem has not been detected because the use of a target operand +with Index() is very rare. + +Fixed a problem with the Index() operator where an attempt was +made to delete the operand objects twice. + +Fixed a problem where an attempt was made to delete an operand +twice during execution of the CondRefOf() operator if the target +did not exist. + +Implemented the first of perhaps several internal create object +functions that create and initialize a specific object type. +This consolidates duplicated code wherever the object is created, +thus shrinking the size of the subsystem. + +Implemented improved debug/error messages for errors that occur +during nested method invocations. All executing method pathnames +are displayed (with the error) as the call stack is unwound - +thus simplifying debug. + +Fixed a problem introduced in the 10/02 release that caused +premature deletion of a buffer object if a buffer was used as an +ASL operand where an integer operand is required (Thus causing an +implicit object conversion from Buffer to Integer.) The change +in the 10/02 release was attempting to fix a memory leak (albeit +incorrectly.) + +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: 71.9K Code, 9.1K Data, 81.0K Total + Debug Version: 153.1K Code, 63.3K Data, 216.4K Total + Current Release: + Non-Debug Version: 71.3K Code, 9.0K Data, 80.3K Total + Debug Version: 152.7K Code, 63.2K Data, 215.5K Total + + +2) Linux + +Changed the implementation of the ACPI semaphores to use down() +instead of down_interruptable(). It is important that the +execution of ACPI control methods not be interrupted by signals. +Methods must run to completion, or the system may be left in an +unknown/unstable state. + +Fixed a compilation error when CONFIG_SOFTWARE_SUSPEND is not +set. (Shawn Starr) + + +3) iASL Compiler/Disassembler + + +Changed the default location of output files. All output files +are now placed in the current directory by default instead of in +the directory of the source file. This change may affect some +existing makefiles, but it brings the behavior of the compiler in +line with other similar tools. The location of the output files +can be overridden with the -p command line switch. + + +---------------------------------------- +11 November 2002. Summary of changes for version 20021111. + + +0) ACPI Specification 2.0B is released and is now available at: +http://www.acpi.info/index.html + + +1) ACPI CA Core Subsystem: + +Implemented support for the ACPI 2.0 SMBus Operation Regions. +This includes the early detection and handoff of the request to +the SMBus region handler (avoiding all of the complex field +support code), and support for the bidirectional return packet +from an SMBus write operation. This paves the way for the +development of SMBus drivers in each host operating system. + +Fixed a problem where the semaphore WAIT_FOREVER constant was +defined as 32 bits, but must be 16 bits according to the ACPI +specification. This had the side effect of causing ASL +Mutex/Event timeouts even though the ASL code requested a wait +forever. Changed all internal references to the ACPI timeout +parameter to 16 bits to prevent future problems. Changed the +name of WAIT_FOREVER to ACPI_WAIT_FOREVER. + +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: 71.4K Code, 9.0K Data, 80.4K Total + Debug Version: 152.3K Code, 63.0K Data, 215.3K Total + Current Release: + Non-Debug Version: 71.9K Code, 9.1K Data, 81.0K Total + Debug Version: 153.1K Code, 63.3K Data, 216.4K Total + + +2) Linux + +Module loading/unloading fixes (John Cagle) + + +3) iASL Compiler/Disassembler + +Added support for the SMBBlockProcessCall keyword (ACPI 2.0) + +Implemented support for the disassembly of all SMBus protocol +keywords (SMBQuick, SMBWord, etc.) + +---------------------------------------- +01 November 2002. Summary of changes for version 20021101. + + +1) ACPI CA Core Subsystem: + +Fixed a problem where platforms that have a GPE1 block but no +GPE0 block were not handled correctly. This resulted in a "GPE +overlap" error message. GPE0 is no longer required. + +Removed code added in the previous release that inserted nodes +into the namespace in alphabetical order. This caused some side- +effects on various machines. The root cause of the problem is +still under investigation since in theory, the internal ordering +of the namespace nodes should not matter. + + +Enhanced error reporting for the case where a named object is not +found during control method execution. The full ACPI namepath +(name reference) of the object that was not found is displayed in +this case. + +Note: as a result of the overhaul of the namespace object types +in the previous release, the namespace nodes for the predefined +scopes (_TZ, _PR, etc.) are now of the type ACPI_TYPE_LOCAL_SCOPE +instead of ACPI_TYPE_ANY. This simplifies the namespace +management code but may affect code that walks the namespace tree +looking for specific object types. + +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: 70.7K Code, 8.6K Data, 79.3K Total + Debug Version: 151.7K Code, 62.4K Data, 214.1K Total + Current Release: + Non-Debug Version: 71.4K Code, 9.0K Data, 80.4K Total + Debug Version: 152.3K Code, 63.0K Data, 215.3K Total + + +2) Linux + +Fixed a problem introduced in the previous release where the +Processor and Thermal objects were not recognized and installed +in /proc. This was related to the scope type change described +above. + + +3) iASL Compiler/Disassembler + +Implemented the -g option to get all of the required ACPI tables +from the registry and save them to files (Windows version of the +compiler only.) The required tables are the FADT, FACS, and +DSDT. + +Added ACPI table checksum validation during table disassembly in +order to catch corrupted tables. + + +---------------------------------------- +22 October 2002. Summary of changes for version 20021022. + +1) ACPI CA Core Subsystem: + +Implemented a restriction on the Scope operator that the target +must already exist in the namespace at the time the operator is +encountered (during table load or method execution). In other +words, forward references are not allowed and Scope() cannot +create a new object. This changes the previous behavior where the +interpreter would create the name if not found. This new +behavior correctly enables the search-to-root algorithm during +namespace lookup of the target name. Because of this upsearch, +this fixes the known Compaq _SB_.OKEC problem and makes both the +AML interpreter and iASL compiler compatible with other ACPI +implementations. + +Completed a major overhaul of the internal ACPI object types for +the ACPI Namespace and the associated operand objects. Many of +these types had become obsolete with the introduction of the two- +pass namespace load. This cleanup simplifies the code and makes +the entire namespace load mechanism much clearer and easier to +understand. + +Improved debug output for tracking scope opening/closing to help +diagnose scoping issues. The old scope name as well as the new +scope name are displayed. Also improved error messages for +problems with ASL Mutex objects and error messages for GPE +problems. + +Cleaned up the namespace dump code, removed obsolete code. + +All string output (for all namespace/object dumps) now uses the +common ACPI string output procedure which handles escapes +properly and does not emit non-printable characters. + +Fixed some issues with constants in the 64-bit version of the +local C library (utclib.c) + + +2) Linux + +EC Driver: No longer attempts to acquire the Global Lock at +interrupt level. + + +3) iASL Compiler/Disassembler + +Implemented ACPI 2.0B grammar change that disallows all Type 1 +and 2 opcodes outside of a control method. This means that the +"executable" operators (versus the "namespace" operators) cannot +be used at the table level; they can only be used within a +control method. + +Implemented the restriction on the Scope() operator where the +target must already exist in the namespace at the time the +operator is encountered (during ASL compilation). In other words, +forward references are not allowed and Scope() cannot create a +new object. This makes the iASL compiler compatible with other +ACPI implementations and makes the Scope() implementation adhere +to the ACPI specification. + +Fixed a problem where namepath optimization for the Alias +operator was optimizing the wrong path (of the two namepaths.) +This caused a "Missing alias link" error message. + +Fixed a problem where an "unknown reserved name" warning could be +incorrectly generated for names like "_SB" when the trailing +underscore is not used in the original ASL. + +Fixed a problem where the reserved name check did not handle +NamePaths with multiple NameSegs correctly. The first nameseg of +the NamePath was examined instead of the last NameSeg. + + +---------------------------------------- + +02 October 2002. Summary of changes for this release. + + +1) ACPI CA Core Subsystem version 20021002: + +Fixed a problem where a store/copy of a string to an existing +string did not always set the string length properly in the +String object. + +Fixed a reported problem with the ToString operator where the +behavior was identical to the ToHexString operator instead of +just simply converting a raw buffer to a string data type. + +Fixed a problem where CopyObject and the other "explicit" +conversion operators were not updating the internal namespace +node type as part of the store operation. + +Fixed a memory leak during implicit source operand conversion +where the original object was not deleted if it was converted to +a new object of a different type. + +Enhanced error messages for all problems associated with +namespace lookups. Common procedure generates and prints the +lookup name as well as the formatted status. + +Completed implementation of a new design for the Alias support +within the namespace. The existing design did not handle the +case where a new object was assigned to one of the two names due +to the use of an explicit conversion operator, resulting in the +two names pointing to two different objects. The new design +simply points the Alias name to the original name node - not to +the object. This results in a level of indirection that must be +handled in the name resolution mechanism. + +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 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: 69.6K Code, 8.3K Data, 77.9K Total + Debug Version: 150.0K Code, 61.7K Data, 211.7K Total + Current Release: + Non-Debug Version: 70.7K Code, 8.6K Data, 79.3K Total + Debug Version: 151.7K Code, 62.4K Data, 214.1K Total + + +2) Linux + +Initialize thermal driver's timer before it is used. (Knut +Neumann) + +Allow handling negative celsius values. (Kochi Takayoshi) + +Fix thermal management and make trip points. R/W (Pavel Machek) + +Fix /proc/acpi/sleep. (P. Christeas) + +IA64 fixes. (David Mosberger) + +Fix reversed logic in blacklist code. (Sergio Monteiro Basto) + +Replace ACPI_DEBUG define with ACPI_DEBUG_OUTPUT. (Dominik +Brodowski) + + +3) iASL Compiler/Disassembler + +Clarified some warning/error messages. + + +---------------------------------------- +18 September 2002. Summary of changes for this release. + + +1) ACPI CA Core Subsystem version 20020918: + +Fixed a reported problem with reference chaining (via the Index() +and RefOf() operators) in the ObjectType() and SizeOf() +operators. The definition of these operators includes the +dereferencing of all chained references to return information on +the base object. + +Fixed a problem with stores to indexed package elements - the +existing code would not complete the store if an "implicit +conversion" was not performed. In other words, if the existing +object (package element) was to be replaced completely, the code +didn't handle this case. + +Relaxed typechecking on the ASL "Scope" operator to allow the +target name to refer to an object of type Integer, String, or +Buffer, in addition to the scoping object types (Device, +predefined Scopes, Processor, PowerResource, and ThermalZone.) +This allows existing AML code that has workarounds for a bug in +Windows to function properly. A warning is issued, however. +This affects both the AML interpreter and the iASL compiler. +Below is an example of this type of ASL code: + + Name(DEB,0x00) + Scope(DEB) + { + +Fixed some reported problems with 64-bit integer support in the +local implementation of C library functions (clib.c) + + +2) Linux + +Use ACPI fix map region instead of IOAPIC region, since it is +undefined in non-SMP. + +Ensure that the SCI has the proper polarity and trigger, even on +systems that do not have an interrupt override entry in the MADT. + +2.5 big driver reorganization (Pat Mochel) + +Use early table mapping code from acpitable.c (Andi Kleen) + +New blacklist entries (Andi Kleen) + +Blacklist improvements. Split blacklist code out into a separate +file. Move checking the blacklist to very early. Previously, we +would use ACPI tables, and then halfway through init, check the +blacklist -- too late. Now, it's early enough to completely fall- +back to non-ACPI. + + +3) iASL Compiler/Disassembler version 20020918: + +Fixed a problem where the typechecking code didn't know that an +alias could point to a method. In other words, aliases were not +being dereferenced during typechecking. + + +---------------------------------------- +29 August 2002. Summary of changes for this release. + +1) ACPI CA Core Subsystem Version 20020829: + +If the target of a Scope() operator already exists, it must be an +object type that actually opens a scope -- such as a Device, +Method, Scope, etc. This is a fatal runtime error. Similar +error check has been added to the iASL compiler also. + +Tightened up the namespace load to disallow multiple names in the +same scope. This previously was allowed if both objects were of +the same type. (i.e., a lookup was the same as entering a new +name). + + +2) Linux + +Ensure that the ACPI interrupt has the proper trigger and +polarity. + +local_irq_disable is extraneous. (Matthew Wilcox) + +Make "acpi=off" actually do what it says, and not use the ACPI +interpreter *or* the tables. + +Added arch-neutral support for parsing SLIT and SRAT tables +(Kochi Takayoshi) + + +3) iASL Compiler/Disassembler Version 20020829: + +Implemented namepath optimization for name declarations. For +example, a declaration like "Method (\_SB_.ABCD)" would get +optimized to "Method (ABCD)" if the declaration is within the +\_SB_ scope. This optimization is in addition to the named +reference path optimization first released in the previous +version. This would seem to complete all possible optimizations +for namepaths within the ASL/AML. + +If the target of a Scope() operator already exists, it must be an +object type that actually opens a scope -- such as a Device, +Method, Scope, etc. + +Implemented a check and warning for unreachable code in the same +block below a Return() statement. + +Fixed a problem where the listing file was not generated if the +compiler aborted if the maximum error count was exceeded (200). + +Fixed a problem where the typechecking of method return values +was broken. This includes the check for a return value when the +method is invoked as a TermArg (a return value is expected.) + +Fixed a reported problem where EOF conditions during a quoted +string or comment caused a fault. + + +---------------------------------------- +15 August 2002. Summary of changes for this release. + +1) ACPI CA Core Subsystem Version 20020815: + +Fixed a reported problem where a Store to a method argument that +contains a reference did not perform the indirect store +correctly. This problem was created during the conversion to the +new reference object model - the indirect store to a method +argument code was not updated to reflect the new model. + +Reworked the ACPI mode change code to better conform to ACPI 2.0, +handle corner cases, and improve code legibility (Kochi +Takayoshi) + +Fixed a problem with the pathname parsing for the carat (^) +prefix. The heavy use of the carat operator by the new namepath +optimization in the iASL compiler uncovered a problem with the +AML interpreter handling of this prefix. In the case where one +or more carats precede a single nameseg, the nameseg was treated +as standalone and the search rule (to root) was inadvertently +applied. This could cause both the iASL compiler and the +interpreter to find the wrong object or to miss the error that +should occur if the object does not exist at that exact pathname. + +Found and fixed the problem where the HP Pavilion DSDT would not +load. This was a relatively minor tweak to the table loading +code (a problem caused by the unexpected encounter with a method +invocation not within a control method), but it does not solve +the overall issue of the execution of AML code at the table +level. This investigation is still ongoing. + +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 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: 69.1K Code, 8.2K Data, 77.3K Total + Debug Version: 149.4K Code, 61.6K Data, 211.0K Total + Current Release: + Non-Debug Version: 69.6K Code, 8.3K Data, 77.9K Total + Debug Version: 150.0K Code, 61.7K Data, 211.7K Total + + +2) Linux + +Remove redundant slab.h include (Brad Hards) + +Fix several bugs in thermal.c (Herbert Nachtnebel) + +Make CONFIG_ACPI_BOOT work properly (Pavel Machek) + +Change acpi_system_suspend to use updated irq functions (Pavel +Machek) + +Export acpi_get_firmware_table (Matthew Wilcox) + +Use proper root proc entry for ACPI (Kochi Takayoshi) + +Fix early-boot table parsing (Bjorn Helgaas) + + +3) iASL Compiler/Disassembler + +Reworked the compiler options to make them more consistent and to +use two-letter options where appropriate. We were running out of +sensible letters. This may break some makefiles, so check the +current options list by invoking the compiler with no parameters. + +Completed the design and implementation of the ASL namepath +optimization option for the compiler. This option optimizes all +references to named objects to the shortest possible path. The +first attempt tries to utilize a single nameseg (4 characters) +and the "search-to-root" algorithm used by the interpreter. If +that cannot be used (because either the name is not in the search +path or there is a conflict with another object with the same +name), the pathname is optimized using the carat prefix (usually +a shorter string than specifying the entire path from the root.) + +Implemented support to obtain the DSDT from the Windows registry +(when the disassembly option is specified with no input file). +Added this code as the implementation for AcpiOsTableOverride in +the Windows OSL. Migrated the 16-bit code (used in the AcpiDump +utility) to scan memory for the DSDT to the AcpiOsTableOverride +function in the DOS OSL to make the disassembler truly OS +independent. + +Implemented a new option to disassemble and compile in one step. +When used without an input filename, this option will grab the +DSDT from the local machine, disassemble it, and compile it in +one step. + +Added a warning message for invalid escapes (a backslash followed +by any character other than the allowable escapes). This catches +the quoted string error "\_SB_" (which should be "\\_SB_" ). +Also, there are numerous instances in the ACPI specification +where this error occurs. + +Added a compiler option to disable all optimizations. This is +basically the "compatibility mode" because by using this option, +the AML code will come out exactly the same as other ASL +compilers. + +Added error messages for incorrectly ordered dependent resource +functions. This includes: missing EndDependentFn macro at end of +dependent resource list, nested dependent function macros (both +start and end), and missing StartDependentFn macro. These are +common errors that should be caught at compile time. + +Implemented _OSI support for the disassembler and compiler. _OSI +must be included in the namespace for proper disassembly (because +the disassembler must know the number of arguments.) + +Added an "optimization" message type that is optional (off by +default). This message is used for all optimizations - including +constant folding, integer optimization, and namepath +optimization. + +---------------------------------------- +25 July 2002. Summary of changes for this release. + + +1) ACPI CA Core Subsystem Version 20020725: + +The AML Disassembler has been enhanced to produce compilable ASL +code and has been integrated into the iASL compiler (see below) +as well as the single-step disassembly for the AML debugger and +the disassembler for the AcpiDump utility. All ACPI 2.0A +opcodes, resource templates and macros are fully supported. The +disassembler has been tested on over 30 different AML files, +producing identical AML when the resulting disassembled ASL file +is recompiled with the same ASL compiler. + +Modified the Resource Manager to allow zero interrupts and zero +dma channels during the GetCurrentResources call. This was +causing problems on some platforms. + +Added the AcpiOsRedirectOutput interface to the OSL to simplify +output redirection for the AcpiOsPrintf and AcpiOsVprintf +interfaces. + +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 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: 68.7K Code, 7.4K Data, 76.1K Total + Debug Version: 142.9K Code, 58.7K Data, 201.6K Total + Current Release: + Non-Debug Version: 69.1K Code, 8.2K Data, 77.3K Total + Debug Version: 149.4K Code, 61.6K Data, 211.0K Total + + +2) Linux + +Fixed a panic in the EC driver (Dominik Brodowski) + +Implemented checksum of the R/XSDT itself during Linux table scan +(Richard Schaal) + + +3) iASL compiler + +The AML disassembler is integrated into the compiler. The "-d" +option invokes the disassembler to completely disassemble an +input AML file, producing as output a text ASL file with the +extension ".dsl" (to avoid name collisions with existing .asl +source files.) A future enhancement will allow the disassembler +to obtain the BIOS DSDT from the registry under Windows. + +Fixed a problem with the VendorShort and VendorLong resource +descriptors where an invalid AML sequence was created. + +Implemented a fix for BufferData term in the ASL parser. It was +inadvertently defined twice, allowing invalid syntax to pass and +causing reduction conflicts. + +Fixed a problem where the Ones opcode could get converted to a +value of zero if "Ones" was used where a byte, word or dword +value was expected. The 64-bit value is now truncated to the +correct size with the correct value. + + +---------------------------------------- +02 July 2002. Summary of changes for this release. + + +1) ACPI CA Core Subsystem Version 20020702: + +The Table Manager code has been restructured to add several new +features. Tables that are not required by the core subsystem +(other than the FADT, DSDT, FACS, PSDTs, etc.) are no longer +validated in any way and are returned from AcpiGetFirmwareTable +if requested. The AcpiOsTableOverride interface is now called +for each table that is loaded by the subsystem in order to allow +the host to override any table it chooses. Previously, only the +DSDT could be overridden. Added one new files, tbrsdt.c and +tbgetall.c. + +Fixed a problem with the conversion of internal package objects +to external objects (when a package is returned from a control +method.) The return buffer length was set to zero instead of the +proper length of the package object. + +Fixed a reported problem with the use of the RefOf and DeRefOf +operators when passing reference arguments to control methods. A +new type of Reference object is used internally for references +produced by the RefOf operator. + +Added additional error messages in the Resource Manager to +explain AE_BAD_DATA errors when they occur during resource +parsing. + +Split the AcpiEnableSubsystem into two primitives to enable a +finer granularity initialization sequence. These two calls +should be called in this order: AcpiEnableSubsystem (flags), +AcpiInitializeObjects (flags). The flags parameter remains the +same. + + +2) Linux + +Updated the ACPI utilities module to understand the new style of +fully resolved package objects that are now returned from the +core subsystem. This eliminates errors of the form: + + ACPI: PCI Interrupt Routing Table [\_SB_.PCI0.PPB_._PRT] + acpi_utils-0430 [145] acpi_evaluate_reference: + Invalid element in package (not a device reference) + +The method evaluation utility uses the new buffer allocation +scheme instead of calling AcpiEvaluate Object twice. + +Added support for ECDT. This allows the use of the Embedded +Controller before the namespace has been fully initialized, which +is necessary for ACPI 2.0 support, and for some laptops to +initialize properly. (Laptops using ECDT are still rare, so only +limited testing was performed of the added functionality.) + +Fixed memory leaks in the EC driver. + +Eliminated a brittle code structure in acpi_bus_init(). + +Eliminated the acpi_evaluate() helper function in utils.c. It is +no longer needed since acpi_evaluate_object can optionally +allocate memory for the return object. + +Implemented fix for keyboard hang when getting battery readings +on some systems (Stephen White) + +PCI IRQ routing update (Dominik Brodowski) + +Fix an ifdef to allow compilation on UP with LAPIC but no IOAPIC +support + +---------------------------------------- +11 June 2002. Summary of changes for this release. + + +1) ACPI CA Core Subsystem Version 20020611: + +Fixed a reported problem where constants such as Zero and One +appearing within _PRT packages were not handled correctly within +the resource manager code. Originally reported against the ASL +compiler because the code generator now optimizes integers to +their minimal AML representation (i.e. AML constants if +possible.) The _PRT code now handles all AML constant opcodes +correctly (Zero, One, Ones, Revision). + +Fixed a problem with the Concatenate operator in the AML +interpreter where a buffer result object was incorrectly marked +as not fully evaluated, causing a run-time error of +AE_AML_INTERNAL. + +All package sub-objects are now fully resolved before they are +returned from the external ACPI interfaces. This means that name +strings are resolved to object handles, and constant operators +(Zero, One, Ones, Revision) are resolved to Integers. + +Implemented immediate resolution of the AML Constant opcodes +(Zero, One, Ones, Revision) to Integer objects upon detection +within the AML stream. This has simplified and reduced the +generated code size of the subsystem by eliminating about 10 +switch statements for these constants (which previously were +contained in Reference objects.) The complicating issues are +that the Zero opcode is used as a "placeholder" for unspecified +optional target operands and stores to constants are defined to +be no-ops. + +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 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: 69.3K Code, 7.4K Data, 76.7K Total + Debug Version: 143.8K Code, 58.8K Data, 202.6K Total + Current Release: + Non-Debug Version: 68.7K Code, 7.4K Data, 76.1K Total + Debug Version: 142.9K Code, 58.7K Data, 201.6K Total + + +2) Linux + +Added preliminary support for obtaining _TRA data for PCI root +bridges (Bjorn Helgaas). + + +3) iASL Compiler Version X2046: + +Fixed a problem where the "_DDN" reserved name was defined to be +a control method with one argument. There are no arguments, and +_DDN does not have to be a control method. + +Fixed a problem with the Linux version of the compiler where the +source lines printed with error messages were the wrong lines. +This turned out to be the "LF versus CR/LF" difference between +Windows and Unix. This appears to be the longstanding issue +concerning listing output and error messages. + +Fixed a problem with the Linux version of compiler where opcode +names within error messages were wrong. This was caused by a +slight difference in the output of the Flex tool on Linux versus +Windows. + +Fixed a problem with the Linux compiler where the hex output +files contained some garbage data caused by an internal buffer +overrun. + + +---------------------------------------- +17 May 2002. Summary of changes for this release. + + +1) ACPI CA Core Subsystem Version 20020517: + +Implemented a workaround to an BIOS bug discovered on the HP +OmniBook where the FADT revision number and the table size are +inconsistent (ACPI 2.0 revision vs. ACPI 1.0 table size). The +new behavior is to fallback to using only the ACPI 1.0 fields of +the FADT if the table is too small to be a ACPI 2.0 table as +claimed by the revision number. Although this is a BIOS bug, +this is a case where the workaround is simple enough and with no +side effects, so it seemed prudent to add it. A warning message +is issued, however. + +Implemented minimum size checks for the fixed-length ACPI tables +-- the FADT and FACS, as well as consistency checks between the +revision number and the table size. + +Fixed a reported problem in the table override support where the +new table pointer was incorrectly treated as a physical address +instead of a logical address. + +Eliminated the use of the AE_AML_ERROR exception and replaced it +with more descriptive codes. + +Fixed a problem where an exception would occur if an ASL Field +was defined with no named Field Units underneath it (used by some +index fields). + +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 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: 68.8K Code, 7.1K Data, 75.9K Total + Debug Version: 142.9K Code, 58.4K Data, 201.3K Total + Current Release: + Non-Debug Version: 69.3K Code, 7.4K Data, 76.7K Total + Debug Version: 143.8K Code, 58.8K Data, 202.6K Total + + + +2) Linux + +Much work done on ACPI init (MADT and PCI IRQ routing support). +(Paul D. and Dominik Brodowski) + +Fix PCI IRQ-related panic on boot (Sam Revitch) + +Set BM_ARB_DIS when entering a sleep state (Ducrot Bruno) + +Fix "MHz" typo (Dominik Brodowski) + +Fix RTC year 2000 issue (Dominik Brodowski) + +Preclude multiple button proc entries (Eric Brunet) + +Moved arch-specific code out of include/platform/aclinux.h + +3) iASL Compiler Version X2044: + +Implemented error checking for the string used in the EISAID +macro (Usually used in the definition of the _HID object.) The +code now strictly enforces the PnP format - exactly 7 characters, +3 uppercase letters and 4 hex digits. + +If a raw string is used in the definition of the _HID object +(instead of the EISAID macro), the string must contain all +alphanumeric characters (e.g., "*PNP0011" is not allowed because +of the asterisk.) + +Implemented checking for invalid use of ACPI reserved names for +most of the name creation operators (Name, Device, Event, Mutex, +OperationRegion, PowerResource, Processor, and ThermalZone.) +Previously, this check was only performed for control methods. + +Implemented an additional check on the Name operator to emit an +error if a reserved name that must be implemented in ASL as a +control method is used. We know that a reserved name must be a +method if it is defined with input arguments. + +The warning emitted when a namespace object reference is not +found during the cross reference phase has been changed into an +error. The "External" directive should be used for names defined +in other modules. + + +4) Tools and Utilities + +The 16-bit tools (adump16 and aexec16) have been regenerated and +tested. + +Fixed a problem with the output of both acpidump and adump16 +where the indentation of closing parentheses and brackets was not +aligned properly with the parent block. + + +---------------------------------------- +03 May 2002. Summary of changes for this release. + + +1) ACPI CA Core Subsystem Version 20020503: + +Added support a new OSL interface that allows the host operating +system software to override the DSDT found in the firmware - +AcpiOsTableOverride. With this interface, the OSL can examine +the version of the firmware DSDT and replace it with a different +one if desired. + +Added new external interfaces for accessing ACPI registers from +device drivers and other system software - AcpiGetRegister and +AcpiSetRegister. This was simply an externalization of the +existing AcpiHwBitRegister interfaces. + +Fixed a regression introduced in the previous build where the +ASL/AML CreateField operator always returned an error, +"destination must be a NS Node". + +Extended the maximum time (before failure) to successfully enable +ACPI mode to 3 seconds. + +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 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: 68.5K Code, 7.0K Data, 75.5K Total + Debug Version: 142.4K Code, 58.3K Data, 200.7K Total + Current Release: + Non-Debug Version: 68.8K Code, 7.1K Data, 75.9K Total + Debug Version: 142.9K Code, 58.4K Data, 201.3K Total + + +2) Linux + +Enhanced ACPI init code for SMP. We are now fully MPS and $PIR- +free. While 3 out of 4 of our in-house systems work fine, the +last one still hangs when testing the LAPIC timer. + +Renamed many files in 2.5 kernel release to omit "acpi_" from the +name. + +Added warning on boot for Presario 711FR. + +Sleep improvements (Pavel Machek) + +ACPI can now be built without CONFIG_PCI enabled. + +IA64: Fixed memory map functions (JI Lee) + + +3) iASL Compiler Version X2043: + +Added support to allow the compiler to be integrated into the MS +VC++ development environment for one-button compilation of single +files or entire projects -- with error-to-source-line mapping. + +Implemented support for compile-time constant folding for the +Type3, Type4, and Type5 opcodes first defined in the ACPI 2.0 +specification. This allows the ASL writer to use expressions +instead of Integer/Buffer/String constants in terms that must +evaluate to constants at compile time and will also simplify the +emitted AML in any such sub-expressions that can be folded +(evaluated at compile-time.) This increases the size of the +compiler significantly because a portion of the ACPI CA AML +interpreter is included within the compiler in order to pre- +evaluate constant expressions. + + +Fixed a problem with the "Unicode" ASL macro that caused the +compiler to fault. (This macro is used in conjunction with the +_STR reserved name.) + +Implemented an AML opcode optimization to use the Zero, One, and +Ones opcodes where possible to further reduce the size of integer +constants and thus reduce the overall size of the generated AML +code. + +Implemented error checking for new reserved terms for ACPI +version 2.0A. + +Implemented the -qr option to display the current list of ACPI +reserved names known to the compiler. + +Implemented the -qc option to display the current list of ASL +operators that are allowed within constant expressions and can +therefore be folded at compile time if the operands are +constants. + + +4) Documentation + +Updated the Programmer's Reference for new interfaces, data +types, and memory allocation model options. + +Updated the iASL Compiler User Reference to apply new format and +add information about new features and options. + +---------------------------------------- +19 April 2002. Summary of changes for this release. + +1) ACPI CA Core Subsystem Version 20020419: + +The source code base for the Core Subsystem has been completely +cleaned with PC-lint (FlexLint) for both 32-bit and 64-bit +versions. The Lint option files used are included in the +/acpi/generate/lint directory. + +Implemented enhanced status/error checking across the entire +Hardware manager subsystem. Any hardware errors (reported from +the OSL) are now bubbled up and will abort a running control +method. + +Fixed a problem where the per-ACPI-table integer width (32 or 64) +was stored only with control method nodes, causing a fault when +non-control method code was executed during table loading. The +solution implemented uses a global variable to indicate table +width across the entire ACPI subsystem. Therefore, ACPI CA does +not support mixed integer widths across different ACPI tables +(DSDT, SSDT). + +Fixed a problem where NULL extended fields (X fields) in an ACPI +2.0 ACPI FADT caused the table load to fail. Although the +existing ACPI specification is a bit fuzzy on this topic, the new +behavior is to fall back on a ACPI 1.0 field if the corresponding +ACPI 2.0 X field is zero (even though the table revision +indicates a full ACPI 2.0 table.) The ACPI specification will be +updated to clarify this issue. + +Fixed a problem with the SystemMemory operation region handler +where memory was always accessed byte-wise even if the AML- +specified access width was larger than a byte. This caused +problems on systems with memory-mapped I/O. Memory is now +accessed with the width specified. On systems that do not +support non-aligned transfers, a check is made to guarantee +proper address alignment before proceeding in order to avoid an +AML-caused alignment fault within the kernel. + + +Fixed a problem with the ExtendedIrq resource where only one byte +of the 4-byte Irq field was extracted. + +Fixed the AcpiExDigitsNeeded() procedure to support _UID. This +function was out of date and required a rewrite. + +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 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: 66.6K Code, 6.5K Data, 73.1K Total + Debug Version: 139.8K Code, 57.4K Data, 197.2K Total + Current Release: + Non-Debug Version: 68.5K Code, 7.0K Data, 75.5K Total + Debug Version: 142.4K Code, 58.3K Data, 200.7K Total + + +2) Linux + +PCI IRQ routing fixes (Dominik Brodowski) + + +3) iASL Compiler Version X2042: + +Implemented an additional compile-time error check for a field +unit whose size + minimum access width would cause a run-time +access beyond the end-of-region. Previously, only the field size +itself was checked. + +The Core subsystem and iASL compiler now share a common parse +object in preparation for compile-time evaluation of the type +3/4/5 ASL operators. + + +---------------------------------------- +Summary of changes for this release: 03_29_02 + +1) ACPI CA Core Subsystem Version 20020329: + +Implemented support for late evaluation of TermArg operands to +Buffer and Package objects. This allows complex expressions to +be used in the declarations of these object types. + +Fixed an ACPI 1.0 compatibility issue when reading Fields. In +ACPI 1.0, if the field was larger than 32 bits, it was returned +as a buffer - otherwise it was returned as an integer. In ACPI +2.0, the field is returned as a buffer only if the field is +larger than 64 bits. The TableRevision is now considered when +making this conversion to avoid incompatibility with existing ASL +code. + +Implemented logical addressing for AcpiOsGetRootPointer. This +allows an RSDP with either a logical or physical address. With +this support, the host OS can now override all ACPI tables with +one logical RSDP. Includes implementation of "typed" pointer +support to allow a common data type for both physical and logical +pointers internally. This required a change to the +AcpiOsGetRootPointer interface. + +Implemented the use of ACPI 2.0 Generic Address Structures for +all GPE, Fixed Event, and PM Timer I/O. This allows the use of +memory mapped I/O for these ACPI features. + +Initialization now ignores not only non-required tables (All +tables other than the FADT, FACS, DSDT, and SSDTs), but also does +not validate the table headers of unrecognized tables. + +Fixed a problem where a notify handler could only be +installed/removed on an object of type Device. All "notify" +objects are now supported -- Devices, Processor, Power, and +Thermal. + +Removed most verbosity from the ACPI_DB_INFO debug level. Only +critical information is returned when this debug level is +enabled. + +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 larger code and data size.

The +'limit' and 'performance' interface (/proc) are fully functional. +[Note that basic policy for controlling performance state +transitions will be included in the next version of ospmd.] The +idle handler was modified to more aggressively use C2, and PIIX4 +errata handling underwent a complete overhaul (big thanks to +Dominik Brodowski). + +Added support for ACPI-PCI device binding (acpi_pci_root.c). _ADR- +based devices in the ACPI namespace are now dynamically bound +(associated) with their PCI counterparts (e.g. PCI1->01:00.0). +This allows, among other things, ACPI to resolve bus numbers for +subordinate PCI bridges. + +Enhanced PCI IRQ routing to get the proper bus number for _PRT +entries defined underneath PCI bridges. + +Added IBM 600E to bad bios list due to invalid _ADR value for +PIIX4 PCI-ISA bridge, resulting in improper PCI IRQ routing. + +In the process of adding full MADT support (e.g. IOAPIC) for IA32 +(acpi.c, mpparse.c) -- stay tuned. + +Added back visual differentiation between fixed-feature and +control-method buttons in dmesg. Buttons are also subtyped (e.g. +button/power/PWRF) to simplify button identification. + +We no longer use -Wno-unused when compiling debug. Please ignore +any "_THIS_MODULE defined but not used" messages. + +Can now shut down the system using "magic sysrq" key. + + +3) iASL Compiler version 2041: + +Fixed a problem where conversion errors for hex/octal/decimal +constants were not reported. + +Implemented a fix for the General Register template Address +field. This field was 8 bits when it should be 64. + +Fixed a problem where errors/warnings were no longer being +emitted within the listing output file. + +Implemented the ACPI 2.0A restriction on ACPI Table Signatures to +exactly 4 characters, alphanumeric only. + + + + +---------------------------------------- +Summary of changes for this release: 03_08_02 + + +1) ACPI CA Core Subsystem Version 20020308: + +Fixed a problem with AML Fields where the use of the "AccessAny" +keyword could cause an interpreter error due to attempting to +read or write beyond the end of the parent Operation Region. + +Fixed a problem in the SystemMemory Operation Region handler +where an attempt was made to map memory beyond the end of the +region. This was the root cause of the "AE_ERROR" and +"AE_NO_MEMORY" errors on some Linux systems. + +Fixed a problem where the interpreter/namespace "search to root" +algorithm was not functioning for some object types. Relaxed the +internal restriction on the search to allow upsearches for all +external object types as well as most internal types. + + +2) Linux: + +We now use safe_halt() macro versus individual calls to sti | +hlt. + +Writing to the processor limit interface should now work. "echo +1" will increase the limit, 2 will decrease, and 0 will reset to +the default. + + +3) ASL compiler: + +Fixed segfault on Linux version. + + +---------------------------------------- +Summary of changes for this release: 02_25_02 + +1) ACPI CA Core Subsystem: + + +Fixed a problem where the GPE bit masks were not initialized +properly, causing erratic GPE behavior. + +Implemented limited support for multiple calling conventions. +The code can be generated with either the VPL (variable parameter +list, or "C") convention, or the FPL (fixed parameter list, or +"Pascal") convention. The core subsystem is about 3.4% smaller +when generated with FPL. + + +2) Linux + +Re-add some /proc/acpi/event functionality that was lost during +the rewrite + +Resolved issue with /proc events for fixed-feature buttons +showing up as the system device. + +Fixed checks on C2/C3 latencies to be inclusive of maximum +values. + +Replaced AE_ERRORs in acpi_osl.c with more specific error codes. + +Changed ACPI PRT option from "pci=noacpi-routing" to "pci=noacpi" + +Fixed limit interface & usage to fix bugs with passive cooling +hysterisis. + +Restructured PRT support. + + +---------------------------------------- +Summary of changes for this label: 02_14_02 + + +1) ACPI CA Core Subsystem: + +Implemented support in AcpiLoadTable to allow loading of FACS and +FADT tables. + +Suport for the now-obsolete interim 0.71 64-bit ACPI tables has +been removed. All 64-bit platforms should be migrated to the +ACPI 2.0 tables. The actbl71.h header has been removed from the +source tree. + +All C macros defined within the subsystem have been prefixed with +"ACPI_" to avoid collision with other system include files. + +Removed the return value for the two AcpiOsPrint interfaces, +since it is never used and causes lint warnings for ignoring the +return value. + +Added error checking to all internal mutex acquire and release +calls. Although a failure from one of these interfaces is +probably a fatal system error, these checks will cause the +immediate abort of the currently executing method or interface. + +Fixed a problem where the AcpiSetCurrentResources interface could +fault. This was a side effect of the deployment of the new +memory allocation model. + +Fixed a couple of problems with the Global Lock support +introduced in the last major build. The "common" (1.0/2.0) +internal FACS was being overwritten with the FACS signature and +clobbering the Global Lock pointer. Also, the actual firmware +FACS was being unmapped after construction of the "common" FACS, +preventing access to the actual Global Lock field within it. The +"common" internal FACS is no longer installed as an actual ACPI +table; it is used simply as a global. + +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 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 (02_07_01) + Non-Debug Version: 65.2K Code, 6.2K Data, 71.4K Total + Debug Version: 136.9K Code, 56.4K Data, 193.3K Total + Current Release: + Non-Debug Version: 65.4K Code, 6.2K Data, 71.6K Total + Debug Version: 138.0K Code, 56.6K Data, 194.6K Total + + +2) Linux + +Updated Linux-specific code for core macro and OSL interface +changes described above. + +Improved /proc/acpi/event. It now can be opened only once and has +proper poll functionality. + +Fixed and restructured power management (acpi_bus). + +Only create /proc "view by type" when devices of that class +exist. + +Fixed "charging/discharging" bug (and others) in acpi_battery. + +Improved thermal zone code. + + +3) ASL Compiler, version X2039: + + +Implemented the new compiler restriction on ASL String hex/octal +escapes to non-null, ASCII values. An error results if an +invalid value is used. (This will require an ACPI 2.0 +specification change.) + +AML object labels that are output to the optional C and ASM +source are now prefixed with both the ACPI table signature and +table ID to help guarantee uniqueness within a large BIOS +project. + + +---------------------------------------- +Summary of changes for this label: 02_01_02 + +1) ACPI CA Core Subsystem: + +ACPI 2.0 support is complete in the entire Core Subsystem and the +ASL compiler. All new ACPI 2.0 operators are implemented and all +other changes for ACPI 2.0 support are complete. With +simultaneous code and data optimizations throughout the +subsystem, ACPI 2.0 support has been implemented with almost no +additional cost in terms of code and data size. + +Implemented a new mechanism for allocation of return buffers. If +the buffer length is set to ACPI_ALLOCATE_BUFFER, the buffer will +be allocated on behalf of the caller. Consolidated all return +buffer validation and allocation to a common procedure. Return +buffers will be allocated via the primary OSL allocation +interface since it appears that a separate pool is not needed by +most users. If a separate pool is required for these buffers, +the caller can still use the original mechanism and pre-allocate +the buffer(s). + +Implemented support for string operands within the DerefOf +operator. + +Restructured the Hardware and Event managers to be table driven, +simplifying the source code and reducing the amount of generated +code. + +Split the common read/write low-level ACPI register bitfield +procedure into a separate read and write, simplifying the code +considerably. + +Obsoleted the AcpiOsCallocate OSL interface. This interface was +used only a handful of times and didn't have enough critical mass +for a separate interface. Replaced with a common calloc +procedure in the core. + +Fixed a reported problem with the GPE number mapping mechanism +that allows GPE1 numbers to be non-contiguous with GPE0. +Reorganized the GPE information and shrunk a large array that was +originally large enough to hold info for all possible GPEs (256) +to simply large enough to hold all GPEs up to the largest GPE +number on the machine. + +Fixed a reported problem with resource structure alignment on 64- +bit platforms. + +Changed the AcpiEnableEvent and AcpiDisableEvent external +interfaces to not require any flags for the common case of +enabling/disabling a GPE. + +Implemented support to allow a "Notify" on a Processor object. + +Most TBDs in comments within the source code have been resolved +and eliminated. + +Fixed a problem in the interpreter where a standalone parent +prefix (^) was not handled correctly in the interpreter and +debugger. + +Removed obsolete and unnecessary GPE save/restore code. + +Implemented Field support in the ASL Load operator. This allows +a table to be loaded from a named field, in addition to loading a +table directly from an Operation Region. + +Implemented timeout and handle support in the external Global +Lock interfaces. + +Fixed a problem in the AcpiDump utility where pathnames were no +longer being generated correctly during the dump of named +objects. + +Modified the AML debugger to give a full display of if/while +predicates instead of just one AML opcode at a time. (The +predicate can have several nested ASL statements.) The old +method was confusing during single stepping. + +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 original ASL +source code is interleaved as C comments. 2) Output the AML in +ASM source code with labels and interleaved ASL source. 3) +Output the AML in raw hex table form, in either C or ASM. + +Implemented support for optional string parameters to the +LoadTable operator. + +Completed support for embedded escape sequences within string +literals. The compiler now supports all single character escapes +as well as the Octal and Hex escapes. Note: the insertion of a +null byte into a string literal (via the hex/octal escape) causes +the string to be immediately terminated. A warning is issued. + +Fixed a problem where incorrect AML was generated for the case +where an ASL namepath consists of a single parent prefix ( + +) with no trailing name segments. + +The compiler has been successfully generated with a 64-bit C +compiler. + + + + +---------------------------------------- +Summary of changes for this label: 12_18_01 + +1) Linux + +Enhanced blacklist with reason and severity fields. Any table's +signature may now be used to identify a blacklisted system. + +Call _PIC control method to inform the firmware which interrupt +model the OS is using. Turn on any disabled link devices. + +Cleaned up busmgr /proc error handling (Andreas Dilger) + + 2) ACPI CA Core Subsystem: + +Implemented ACPI 2.0 semantics for the "Break" operator (Exit +from while loop) + +Completed implementation of the ACPI 2.0 "Continue", +"ConcatenateResTemplate", "DataTableRegion", and "LoadTable" +operators. All new ACPI 2.0 operators are now implemented in +both the ASL compiler and the AML interpreter. The only +remaining ACPI 2.0 task is support for the String data type in +the DerefOf operator. Fixed a problem with AcquireMutex where +the status code was lost if the caller had to actually wait for +the mutex. + +Increased the maximum ASL Field size from 64K bits to 4G bits. + +Completed implementation of the external Global Lock interfaces - +- AcpiAcquireGlobalLock and AcpiReleaseGlobalLock. The Timeout +and Handler parameters were added. + +Completed another pass at removing warnings and issues when +compiling with 64-bit compilers. The code now compiles cleanly +with the Intel 64-bit C/C++ compiler. Most notably, the pointer +add and subtract (diff) macros have changed considerably. + +Created and deployed a new ACPI_SIZE type that is 64-bits wide on +64-bit platforms, 32-bits on all others. This type is used +wherever memory allocation and/or the C sizeof() operator is +used, and affects the OSL memory allocation interfaces +AcpiOsAllocate and AcpiOsCallocate. + +Implemented sticky user breakpoints in the AML debugger. + +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.

This +operator creates a new copy of an object (and is also used to +bypass the "implicit conversion" mechanism of the Store +operator.) + +The ACPI 2.0 semantics for the SizeOf operator are fully +implemented. The change is that performing a SizeOf on a +reference object causes an automatic dereference of the object to +tha actual value before the size is evaluated. This behavior was +undefined in ACPI 1.0. + +The ACPI 2.0 semantics for the Extended IRQ resource descriptor +have been implemented. The interrupt polarity and mode are now +independently set. + +Fixed a problem where ASL Constants (Zero, One, Ones, Revision) +appearing in Package objects were not properly converted to +integers when the internal Package was converted to an external +object (via the AcpiEvaluateObject interface.) + +Fixed a problem with the namespace object deletion mechanism for +objects created by control methods. There were two parts to this +problem: 1) Objects created during the initialization phase +method parse were not being deleted, and 2) The object owner ID +mechanism to track objects was broken. + +Fixed a problem where the use of the ASL Scope operator within a +control method would result in an invalid opcode exception. + +Fixed a problem introduced in the previous label where the buffer +length required for the _PRT structure was not being returned +correctly. + +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.

This +version supports both static and dyanmic PRT entries, but dynamic +entries are treated as if they were static (not yet +reconfigurable). Architecture- specific code to use this data is +absent on IA32 but should be available shortly. + +Changed the initialization sequence to start the ACPI interpreter +(acpi_init) prior to initialization of the PCI driver (pci_init) +in init/main.c. This ordering is required to support PRT and +facilitate other (future) enhancement. A side effect is that the +ACPI bus driver and certain device drivers can no longer be +loaded as modules. + +Modified the 'make menuconfig' options to allow PCI Interrupt +Routing support to be included without the ACPI Bus and other +device drivers. + + 3) ASL Compiler, version X2033: + +Fixed some issues with the use of the new CopyObject and +DataTableRegion operators. Both are fully functional. + + ---------------------------------------- +Summary of changes for this label: 11_20_01 + + 20 November 2001. Summary of changes for this release. + + 1) ACPI CA Core Subsystem: + +Updated Index support to match ACPI 2.0 semantics. Storing a +Integer, String, or Buffer to an Index of a Buffer will store +only the least-significant byte of the source to the Indexed +buffer byte. Multiple writes are not performed. + +Fixed a problem where the access type used in an AccessAs ASL +operator was not recorded correctly into the field object. + +Fixed a problem where ASL Event objects were created in a +signalled state. Events are now created in an unsignalled state. + +The internal object cache is now purged after table loading and +initialization to reduce the use of dynamic kernel memory -- on +the assumption that object use is greatest during the parse phase +of the entire table (versus the run-time use of individual +control methods.) + +ACPI 2.0 variable-length packages are now fully operational. + +Code and Data Size: Code and Data optimizations have permitted +new feature development with an actual reduction in the library +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 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 (11_09_01): + Non-Debug Version: 63.7K Code, 5.2K Data, 68.9K Total + Debug Version: 134.5K Code, 55.4K Data, 189.9K Total + + Current Release: + Non-Debug Version: 64.1K Code, 5.3K Data, 69.4K Total + Debug Version: 135.1K Code, 55.4K Data, 190.5K Total + + 2) Linux: + +Enhanced the ACPI boot-time initialization code to allow the use +of Local APIC tables for processor enumeration on IA-32, and to +pave the way for a fully MPS-free boot (on SMP systems) in the +near future. This functionality replaces +arch/i386/kernel/acpitables.c, which was introduced in an earlier +2.4.15-preX release. To enable this feature you must add +"acpi_boot=on" to the kernel command line -- see the help entry +for CONFIG_ACPI_BOOT for more information. An IA-64 release is +in the works... + +Restructured the configuration options to allow boot-time table +parsing support without inclusion of the ACPI Interpreter (and +other) code. + +NOTE: This release does not include fixes for the reported +events, power-down, and thermal passive cooling issues (coming +soon). + + 3) ASL Compiler: + +Added additional typechecking for Fields within restricted access +Operation Regions. All fields within EC and CMOS regions must be +declared with ByteAcc. All fields withing SMBus regions must be +declared with the BufferAcc access type. + +Fixed a problem where the listing file output of control methods +no longer interleaved the actual AML code with the ASL source +code. + + + +---------------------------------------- +Summary of changes for this label: 11_09_01 + +1) ACPI CA Core Subsystem: + +Implemented ACPI 2.0-defined support for writes to fields with a +Buffer, String, or Integer source operand that is smaller than +the target field. In these cases, the source operand is zero- +extended to fill the target field. + +Fixed a problem where a Field starting bit offset (within the +parent operation region) was calculated incorrectly if the +alignment of the field differed from the access width. This +affected CreateWordField, CreateDwordField, CreateQwordField, and +possibly other fields that use the "AccessAny" keyword. + +Fixed a problem introduced in the 11_02_01 release where indirect +stores through method arguments did not operate correctly. + +2) Linux: + +Implemented boot-time ACPI table parsing support +(CONFIG_ACPI_BOOT) for IA32 and IA64 UP/SMP systems. This code +facilitates the use of ACPI tables (e.g. MADT, SRAT) rather than +legacy BIOS interfaces (e.g. MPS) for the configuration of system +processors, memory, and interrupts during setup_arch(). Note +that this patch does not include the required architecture- +specific changes required to apply this information -- subsequent +patches will be posted for both IA32 and IA64 to achieve this. + +Added low-level sleep support for IA32 platforms, courtesy of Pat +Mochel. This allows IA32 systems to transition to/from various +sleeping states (e.g. S1, S3), although the lack of a centralized +driver model and power-manageable drivers will prevent its +(successful) use on most systems. + +Revamped the ACPI 'menuconfig' layout: created new "ACPI Support" +submenu, unified IA32 and IA64 options, added new "Boot using +ACPI tables" option, etc. + +Increased the default timeout for the EC driver from 1ms to 10ms +(1000 cycles of 10us) to try to address AE_TIME errors during EC +transactions. + + ---------------------------------------- +Summary of changes for this label: 11_02_01 + +1) ACPI CA Core Subsystem: + +ACPI 2.0 Support: Implemented ACPI 2.0 64-bit Field access +(QWordAcc keyword). All ACPI 2.0 64-bit support is now +implemented. + +OSL Interfaces: Several of the OSL (AcpiOs*) interfaces required +changes to support ACPI 2.0 Qword field access. Read/Write +PciConfiguration(), Read/Write Memory(), and Read/Write Port() +now accept an ACPI_INTEGER (64 bits) as the value parameter. +Also, the value parameter for the address space handler interface +is now an ACPI_INTEGER. OSL implementations of these interfaces +must now handle the case where the Width parameter is 64. + +Index Fields: Fixed a problem where unaligned bit assembly and +disassembly for IndexFields was not supported correctly. + +Index and Bank Fields: Nested Index and Bank Fields are now +supported. During field access, a check is performed to ensure +that the value written to an Index or Bank register is not out of +the range of the register. The Index (or Bank) register is +written before each access to the field data. Future support will +include allowing individual IndexFields to be wider than the +DataRegister width. + +Fields: Fixed a problem where the AML interpreter was incorrectly +attempting to write beyond the end of a Field/OpRegion. This was +a boundary case that occurred when a DWORD field was written to a +BYTE access OpRegion, forcing multiple writes and causing the +interpreter to write one datum too many. + +Fields: Fixed a problem with Field/OpRegion access where the +starting bit address of a field was incorrectly calculated if the +current access type was wider than a byte (WordAcc, DwordAcc, or +QwordAcc). + +Fields: Fixed a problem where forward references to individual +FieldUnits (individual Field names within a Field definition) +were not resolved during the AML table load. + +Fields: Fixed a problem where forward references from a Field +definition to the parent Operation Region definition were not +resolved during the AML table load. + +Fields: Duplicate FieldUnit names within a scope are now detected +during AML table load. + +Acpi Interfaces: Fixed a problem where the AcpiGetName() +interface returned an incorrect name for the root node. + +Code and Data Size: Code and Data optimizations have permitted +new feature development with an actual reduction in the library +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 larger +code and data size.

The modules exmonad.c and +exdyadic.c were eliminated. New modules are exoparg1.c, +exoparg2.c, exoparg3.c, and exoparg6.c. + +Support for the ACPI 2.0 "Mid" ASL operator has been implemented. + +Fixed a problem where the AML debugger was causing some internal +objects to not be deleted during subsystem termination. + +Fixed a problem with the external AcpiEvaluateObject interface +where the subsystem would fault if the named object to be +evaluated refered to a constant such as Zero, Ones, etc. + +Fixed a problem with IndexFields and BankFields where the +subsystem would fault if the index, data, or bank registers were +not defined in the same scope as the field itself. + +Added printf format string checking for compilers that support +this feature. Corrected more than 50 instances of issues with +format specifiers within invocations of ACPI_DEBUG_PRINT +throughout the core subsystem code. + +The ASL "Revision" operator now returns the ACPI support level +implemented in the core - the value "2" since the ACPI 2.0 +support is more than 50% implemented. + +Enhanced the output of the AML debugger "dump namespace" command +to output in a more human-readable form. + +Current core subsystem library code 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 full debug trace mechanism -- leading to 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 Label (09_20_01): + Non-Debug Version: 65K Code, 5K Data, 70K Total + Debug Version: 138K Code, 58K Data, 196K Total + + This Label: + + Non-Debug Version: 63.9K Code, 5.1K Data, 69.0K Total + Debug Version: 136.7K Code, 57.4K Data, 194.2K Total + +Linux: + +Implemented a "Bad BIOS Blacklist" to track machines that have +known ASL/AML problems. + +Enhanced the /proc interface for the thermal zone driver and +added support for _HOT (the critical suspend trip point). The +'info' file now includes threshold/policy information, and allows +setting of _SCP (cooling preference) and _TZP (polling frequency) +values to the 'info' file. Examples: "echo tzp=5 > info" sets the +polling frequency to 5 seconds, and "echo scp=1 > info" sets the +cooling preference to the passive/quiet mode (if supported by the +ASL). + +Implemented a workaround for a gcc bug that resuted in an OOPs +when loading the control method battery driver. + + ---------------------------------------- +Summary of changes for this label: 09_20_01 + + ACPI CA Core Subsystem: + +The AcpiEnableEvent and AcpiDisableEvent interfaces have been +modified to allow individual GPE levels to be flagged as wake- +enabled (i.e., these GPEs are to remain enabled when the platform +sleeps.) + +The AcpiEnterSleepState and AcpiLeaveSleepState interfaces now +support wake-enabled GPEs. This means that upon entering the +sleep state, all GPEs that are not wake-enabled are disabled. +When leaving the sleep state, these GPEs are reenabled. + +A local double-precision divide/modulo module has been added to +enhance portability to OS kernels where a 64-bit math library is +not available. The new module is "utmath.c". + +Several optimizations have been made to reduce the use of CPU +stack. Originally over 2K, the maximum stack usage is now below +2K at 1860 bytes (1.82k) + +Fixed a problem with the AcpiGetFirmwareTable interface where the +root table pointer was not mapped into a logical address +properly. + +Fixed a problem where a NULL pointer was being dereferenced in +the interpreter code for the ASL Notify operator. + +Fixed a problem where the use of the ASL Revision operator +returned an error. This operator now returns the current version +of the ACPI CA core subsystem. + +Fixed a problem where objects passed as control method parameters +to AcpiEvaluateObject were always deleted at method termination. +However, these objects may end up being stored into the namespace +by the called method. The object reference count mechanism was +applied to these objects instead of a force delete. + +Fixed a problem where static strings or buffers (contained in the +AML code) that are declared as package elements within the ASL +code could cause a fault because the interpreter would attempt to +delete them. These objects are now marked with the "static +object" flag to prevent any attempt to delete them. + +Implemented an interpreter optimization to use operands directly +from the state object instead of extracting the operands to local +variables. This reduces stack use and code size, and improves +performance. + +The module exxface.c was eliminated as it was an unnecessary +extra layer of code. + +Current core subsystem library code 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 full debug trace mechanism -- leading to 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. + + Non-Debug Version: 65K Code, 5K Data, 70K Total +(Previously 69K) Debug Version: 138K Code, 58K Data, 196K +Total (Previously 195K) + +Linux: + +Support for ACPI 2.0 64-bit integers has been added. All ACPI +Integer objects are now 64 bits wide + +All Acpi data types and structures are now in lower case. Only +Acpi macros are upper case for differentiation. + + Documentation: + +Changes to the external interfaces as described above. + + ---------------------------------------- +Summary of changes for this label: 08_31_01 + + ACPI CA Core Subsystem: + +A bug with interpreter implementation of the ASL Divide operator +was found and fixed. The implicit function return value (not the +explicit store operands) was returning the remainder instead of +the quotient. This was a longstanding bug and it fixes several +known outstanding issues on various platforms. + +The ACPI_DEBUG_PRINT and function trace entry/exit macros have +been further optimized for size. There are 700 invocations of +the DEBUG_PRINT macro alone, so each optimization reduces the +size of the debug version of the subsystem significantly. + +A stack trace mechanism has been implemented. The maximum stack +usage is about 2K on 32-bit platforms. The debugger command +"stat stack" will display the current maximum stack usage. + +All public symbols and global variables within the subsystem are +now prefixed with the string "Acpi". This keeps all of the +symbols grouped together in a kernel map, and avoids conflicts +with other kernel subsystems. + +Most of the internal fixed lookup tables have been moved into the +code segment via the const operator. + +Several enhancements have been made to the interpreter to both +reduce the code size and improve performance. + +Current core subsystem library code 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 full debug trace mechanism which contains over +700 invocations of the DEBUG_PRINT macro, 500 function entry +macro invocations, and over 900 function exit macro invocations - +- leading to 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. + + Non-Debug Version: 64K Code, 5K Data, 69K Total +Debug Version: 137K Code, 58K Data, 195K Total + + Linux: + +Implemented wbinvd() macro, pending a kernel-wide definition. + +Fixed /proc/acpi/event to handle poll() and short reads. + + ASL Compiler, version X2026: + +Fixed a problem introduced in the previous label where the AML +code emitted for package objects produced packages with zero +length. + + ---------------------------------------- +Summary of changes for this label: 08_16_01 + +ACPI CA Core Subsystem: + +The following ACPI 2.0 ASL operators have been implemented in the +AML interpreter (These are already supported by the Intel ASL +compiler): ToDecimalString, ToHexString, ToString, ToInteger, +and ToBuffer. Support for 64-bit AML constants is implemented in +the AML parser, debugger, and disassembler. + +The internal memory tracking mechanism (leak detection code) has +been upgraded to reduce the memory overhead (a separate tracking +block is no longer allocated for each memory allocation), and now +supports all of the internal object caches. + +The data structures and code for the internal object caches have +been coelesced and optimized so that there is a single cache and +memory list data structure and a single group of functions that +implement generic cache management. This has reduced the code +size in both the debug and release versions of the subsystem. + +The DEBUG_PRINT macro(s) have been optimized for size and +replaced by ACPI_DEBUG_PRINT. The syntax for this macro is +slightly different, because it generates a single call to an +internal function. This results in a savings of about 90 bytes +per invocation, resulting in an overall code and data savings of +about 16% in the debug version of the subsystem. + + Linux: + +Fixed C3 disk corruption problems and re-enabled C3 on supporting +machines. + +Integrated low-level sleep code by Patrick Mochel. + +Further tweaked source code Linuxization. + +Other minor fixes. + + ASL Compiler: + +Support for ACPI 2.0 variable length packages is fixed/completed. + +Fixed a problem where the optional length parameter for the ACPI +2.0 ToString operator. + +Fixed multiple extraneous error messages when a syntax error is +detected within the declaration line of a control method. + + ---------------------------------------- +Summary of changes for this label: 07_17_01 + +ACPI CA Core Subsystem: + +Added a new interface named AcpiGetFirmwareTable to obtain any +ACPI table via the ACPI signature. The interface can be called +at any time during kernel initialization, even before the kernel +virtual memory manager is initialized and paging is enabled. +This allows kernel subsystems to obtain ACPI tables very early, +even before the ACPI CA subsystem is initialized. + +Fixed a problem where Fields defined with the AnyAcc attribute +could be resolved to the incorrect address under the following +conditions: 1) the field width is larger than 8 bits and 2) the +parent operation region is not defined on a DWORD boundary. + +Fixed a problem where the interpreter is not being locked during +namespace initialization (during execution of the _INI control +methods), causing an error when an attempt is made to release it +later. + +ACPI 2.0 support in the AML Interpreter has begun and will be +ongoing throughout the rest of this year. In this label, The Mod +operator is implemented. + +Added a new data type to contain full PCI addresses named +ACPI_PCI_ID. This structure contains the PCI Segment, Bus, +Device, and Function values. + + Linux: + +Enhanced the Linux version of the source code to change most +capitalized ACPI type names to lowercase. For example, all +instances of ACPI_STATUS are changed to acpi_status. This will +result in a large diff, but the change is strictly cosmetic and +aligns the CA code closer to the Linux coding standard. + +OSL Interfaces: + +The interfaces to the PCI configuration space have been changed +to add the PCI Segment number and to split the single 32-bit +combined DeviceFunction field into two 16-bit fields. This was +accomplished by moving the four values that define an address in +PCI configuration space (segment, bus, device, and function) to +the new ACPI_PCI_ID structure. + +The changes to the PCI configuration space interfaces led to a +reexamination of the complete set of address space access +interfaces for PCI, I/O, and Memory. The previously existing 18 +interfaces have proven difficult to maintain (any small change +must be propagated across at least 6 interfaces) and do not +easily allow for future expansion to 64 bits if necessary. Also, +on some systems, it would not be appropriate to demultiplex the +access width (8, 16, 32,or 64) before calling the OSL if the +corresponding native OS interfaces contain a similar access width +parameter. For these reasons, the 18 address space interfaces +have been replaced by these 6 new ones: + +AcpiOsReadPciConfiguration +AcpiOsWritePciConfiguration +AcpiOsReadMemory +AcpiOsWriteMemory +AcpiOsReadPort +AcpiOsWritePort + +Added a new interface named AcpiOsGetRootPointer to allow the OSL +to perform the platform and/or OS-specific actions necessary to +obtain the ACPI RSDP table pointer. On IA-32 platforms, this +interface will simply call down to the CA core to perform the low- +memory search for the table. On IA-64, the RSDP is obtained from +EFI. Migrating this interface to the OSL allows the CA core to +remain OS and platform independent. + +Added a new interface named AcpiOsSignal to provide a generic +"function code and pointer" interface for various miscellaneous +signals and notifications that must be made to the host OS. The +first such signals are intended to support the ASL Fatal and +Breakpoint operators. In the latter case, the AcpiOsBreakpoint +interface has been obsoleted. + +The definition of the AcpiFormatException interface has been +changed to simplify its use. The caller no longer must supply a +buffer to the call; A pointer to a const string is now returned +directly. This allows the call to be easily used in printf +statements, etc. since the caller does not have to manage a local +buffer. + + + ASL Compiler, Version X2025: + +The ACPI 2.0 Switch/Case/Default operators have been implemented +and are fully functional. They will work with all ACPI 1.0 +interpreters, since the operators are simply translated to +If/Else pairs. + +The ACPI 2.0 ElseIf operator is implemented and will also work +with 1.0 interpreters, for the same reason. + +Implemented support for ACPI 2.0 variable-length packages. These +packages have a separate opcode, and their size is determined by +the interpreter at run-time. + +Documentation The ACPI CA Programmer Reference has been updated +to reflect the new interfaces and changes to existing interfaces. + + ------------------------------------------ +Summary of changes for this label: 06_15_01 + + ACPI CA Core Subsystem: + +Fixed a problem where a DWORD-accessed field within a Buffer +object would get its byte address inadvertently rounded down to +the nearest DWORD. Buffers are always Byte-accessible. + + ASL Compiler, version X2024: + +Fixed a problem where the Switch() operator would either fault or +hang the compiler. Note however, that the AML code for this ACPI +2.0 operator is not yet implemented. + +Compiler uses the new AcpiOsGetTimer interface to obtain compile +timings. + +Implementation of the CreateField operator automatically converts +a reference to a named field within a resource descriptor from a +byte offset to a bit offset if required. + +Added some missing named fields from the resource descriptor +support. These are the names that are automatically created by +the compiler to reference fields within a descriptor. They are +only valid at compile time and are not passed through to the AML +interpreter. + +Resource descriptor named fields are now typed as Integers and +subject to compile-time typechecking when used in expressions. + + ------------------------------------------ +Summary of changes for this label: 05_18_01 + + ACPI CA Core Subsystem: + +Fixed a couple of problems in the Field support code where bits +from adjacent fields could be returned along with the proper +field bits. Restructured the field support code to improve +performance, readability and maintainability. + +New DEBUG_PRINTP macro automatically inserts the procedure name +into the output, saving hundreds of copies of procedure name +strings within the source, shrinking the memory footprint of the +debug version of the core subsystem. + + Source Code Structure: + +The source code directory tree was restructured to reflect the +current organization of the component architecture. Some files +and directories have been moved and/or renamed. + + Linux: + +Fixed leaking kacpidpc processes. + +Fixed queueing event data even when /proc/acpi/event is not +opened. + + ASL Compiler, version X2020: + +Memory allocation performance enhancement - over 24X compile time +improvement on large ASL files. Parse nodes and namestring +buffers are now allocated from a large internal compiler buffer. + +The temporary .SRC file is deleted unless the "-s" option is +specified + +The "-d" debug output option now sends all output to the .DBG +file instead of the console. + +"External" second parameter is now optional + +"ElseIf" syntax now properly allows the predicate + +Last operand to "Load" now recognized as a Target operand + +Debug object can now be used anywhere as a normal object. + +ResourceTemplate now returns an object of type BUFFER + +EISAID now returns an object of type INTEGER + +"Index" now works with a STRING operand + +"LoadTable" now accepts optional parameters + +"ToString" length parameter is now optional + +"Interrupt (ResourceType," parse error fixed. + +"Register" with a user-defined region space parse error fixed + +Escaped backslash at the end of a string ("\\") scan/parse error +fixed + +"Revision" is now an object of type INTEGER. + + + +------------------------------------------ +Summary of changes for this label: 05_02_01 + +Linux: + +/proc/acpi/event now blocks properly. + +Removed /proc/sys/acpi. You can still dump your DSDT from +/proc/acpi/dsdt. + + ACPI CA Core Subsystem: + +Fixed a problem introduced in the previous label where some of +the "small" resource descriptor types were not recognized. + +Improved error messages for the case where an ASL Field is +outside the range of the parent operation region. + + ASL Compiler, version X2018: + +Added error detection for ASL Fields that extend beyond the +length of the parent operation region (only if the length of the +region is known at compile time.) This includes fields that have +a minimum access width that is smaller than the parent region, +and individual field units that are partially or entirely beyond +the extent of the parent. + + + +------------------------------------------ +Summary of changes for this label: 04_27_01 + + ACPI CA Core Subsystem: + +Fixed a problem where the namespace mutex could be released at +the wrong time during execution of AcpiRemoveAddressSpaceHandler. + +Added optional thread ID output for debug traces, to simplify +debugging of multiple threads. Added context switch notification +when the debug code realizes that a different thread is now +executing ACPI code. + +Some additional external data types have been prefixed with the +string "ACPI_" for consistency. This may effect existing code. +The data types affected are the external callback typedefs - +e.g., WALK_CALLBACK becomes ACPI_WALK_CALLBACK. + + Linux: + +Fixed an issue with the OSL semaphore implementation where a +thread was waking up with an error from receiving a SIGCHLD +signal. + +Linux version of ACPI CA now uses the system C library for string +manipulation routines instead of a local implementation. + +Cleaned up comments and removed TBDs. + + ASL Compiler, version X2017: + +Enhanced error detection and reporting for all file I/O +operations. + + Documentation: + +Programmer Reference updated to version 1.06. + + + +------------------------------------------ +Summary of changes for this label: 04_13_01 + + ACPI CA Core Subsystem: + +Restructured support for BufferFields and RegionFields. +BankFields support is now fully operational. All known 32-bit +limitations on field sizes have been removed. Both BufferFields +and (Operation) RegionFields are now supported by the same field +management code. + +Resource support now supports QWORD address and IO resources. The +16/32/64 bit address structures and the Extended IRQ structure +have been changed to properly handle Source Resource strings. + +A ThreadId of -1 is now used to indicate a "mutex not acquired" +condition internally and must never be returned by +AcpiOsThreadId. This reserved value was changed from 0 since Unix +systems allow a thread ID of 0. + +Linux: + +Driver code reorganized to enhance portability + +Added a kernel configuration option to control ACPI_DEBUG + +Fixed the EC driver to honor _GLK. + +ASL Compiler, version X2016: + +Fixed support for the "FixedHw" keyword. Previously, the FixedHw +address space was set to 0, not 0x7f as it should be. + + ------------------------------------------ +Summary of changes for this label: 03_13_01 + + ACPI CA Core Subsystem: + +During ACPI initialization, the _SB_._INI method is now run if +present. + +Notify handler fix - notifies are deferred until the parent +method completes execution. This fixes the "mutex already +acquired" issue seen occasionally. + +Part of the "implicit conversion" rules in ACPI 2.0 have been +found to cause compatibility problems with existing ASL/AML. The +convert "result-to-target-type" implementation has been removed +for stores to method Args and Locals. Source operand conversion +is still fully implemented. Possible changes to ACPI 2.0 +specification pending. + +Fix to AcpiRsCalculatePciRoutingTableLength to return correct +length. + +Fix for compiler warnings for 64-bit compiles. + + Linux: + +/proc output aligned for easier parsing. + +Release-version compile problem fixed. + +New kernel configuration options documented in Configure.help. + +IBM 600E - Fixed Sleep button may generate "Invalid <NULL> +context" message. + + OSPM: + +Power resource driver integrated with bus manager. + +Fixed kernel fault during active cooling for thermal zones. + +Source Code: + +The source code tree has been restructured. + + + +------------------------------------------ +Summary of changes for this label: 03_02_01 + + Linux OS Services Layer (OSL): + +Major revision of all Linux-specific code. + +Modularized all ACPI-specific drivers. + +Added new thermal zone and power resource drivers. + +Revamped /proc interface (new functionality is under /proc/acpi). + +New kernel configuration options. + + Linux known issues: + +New kernel configuration options not documented in Configure.help +yet. + + +Module dependencies not currently implemented. If used, they +should be loaded in this order: busmgr, power, ec, system, +processor, battery, ac_adapter, button, thermal. + +Modules will not load if CONFIG_MODVERSION is set. + +IBM 600E - entering S5 may reboot instead of shutting down. + +IBM 600E - Sleep button may generate "Invalid <NULL> context" +message. + +Some systems may fail with "execution mutex already acquired" +message. + + ACPI CA Core Subsystem: + +Added a new OSL Interface, AcpiOsGetThreadId. This was required +for the deadlock detection code. Defined to return a non-zero, +32-bit thread ID for the currently executing thread. May be a +non-zero constant integer on single-thread systems. + +Implemented deadlock detection for internal subsystem mutexes. +We may add conditional compilation for this code (debug only) +later. + +ASL/AML Mutex object semantics are now fully supported. This +includes multiple acquires/releases by owner and support for the +Mutex SyncLevel parameter. + +A new "Force Release" mechanism automatically frees all ASL +Mutexes that have been acquired but not released when a thread +exits the interpreter. This forces conformance to the ACPI spec +("All mutexes must be released when an invocation exits") and +prevents deadlocked ASL threads. This mechanism can be expanded +(later) to monitor other resource acquisitions if OEM ASL code +continues to misbehave (which it will). + +Several new ACPI exception codes have been added for the Mutex +support. + +Recursive method calls are now allowed and supported (the ACPI +spec does in fact allow recursive method calls.) The number of +recursive calls is subject to the restrictions imposed by the +SERIALIZED method keyword and SyncLevel (ACPI 2.0) method +parameter. + +Implemented support for the SyncLevel parameter for control +methods (ACPI 2.0 feature) + +Fixed a deadlock problem when multiple threads attempted to use +the interpreter. + +Fixed a problem where the string length of a String package +element was not always set in a package returned from +AcpiEvaluateObject. + +Fixed a problem where the length of a String package element was +not always included in the length of the overall package returned +from AcpiEvaluateObject. + +Added external interfaces (Acpi*) to the ACPI debug memory +manager. This manager keeps a list of all outstanding +allocations, and can therefore detect memory leaks and attempts +to free memory blocks more than once. Useful for code such as the +power manager, etc. May not be appropriate for device drivers. +Performance with the debug code enabled is slow. + +The ACPI Global Lock is now an optional hardware element. + + ASL Compiler Version X2015: + +Integrated changes to allow the compiler to be generated on +multiple platforms. + +Linux makefile added to generate the compiler on Linux + + Source Code: + +All platform-specific headers have been moved to their own +subdirectory, Include/Platform. + +New source file added, Interpreter/ammutex.c + +New header file, Include/acstruct.h + + Documentation: + +The programmer reference has been updated for the following new +interfaces: AcpiOsGetThreadId AcpiAllocate AcpiCallocate AcpiFree + + ------------------------------------------ +Summary of changes for this label: 02_08_01 + +Core ACPI CA Subsystem: Fixed a problem where an error was +incorrectly returned if the return resource buffer was larger +than the actual data (in the resource interfaces). + +References to named objects within packages are resolved to the +full pathname string before packages are returned directly (via +the AcpiEvaluateObject interface) or indirectly via the resource +interfaces. + +Linux OS Services Layer (OSL): + +Improved /proc battery interface. + + +Added C-state debugging output and other miscellaneous fixes. + +ASL Compiler Version X2014: + +All defined method arguments can now be used as local variables, +including the ones that are not actually passed in as parameters. +The compiler tracks initialization of the arguments and issues an +exception if they are used without prior assignment (just like +locals). + +The -o option now specifies a filename prefix that is used for +all output files, including the AML output file. Otherwise, the +default behavior is as follows: 1) the AML goes to the file +specified in the DSDT. 2) all other output files use the input +source filename as the base. + + ------------------------------------------ +Summary of changes for this label: 01_25_01 + +Core ACPI CA Subsystem: Restructured the implementation of object +store support within the interpreter. This includes support for +the Store operator as well as any ASL operators that include a +target operand. + +Partially implemented support for Implicit Result-to-Target +conversion. This is when a result object is converted on the fly +to the type of an existing target object. Completion of this +support is pending further analysis of the ACPI specification +concerning this matter. + +CPU-specific code has been removed from the subsystem (hardware +directory). + +New Power Management Timer functions added + +Linux OS Services Layer (OSL): Moved system state transition code +to the core, fixed it, and modified Linux OSL accordingly. + +Fixed C2 and C3 latency calculations. + + +We no longer use the compilation date for the version message on +initialization, but retrieve the version from +AcpiGetSystemInfo(). + +Incorporated for fix Sony VAIO machines. + +Documentation: The Programmer Reference has been updated and +reformatted. + + +ASL Compiler: Version X2013: Fixed a problem where the line +numbering and error reporting could get out of sync in the +presence of multiple include files. + + ------------------------------------------ +Summary of changes for this label: 01_15_01 + +Core ACPI CA Subsystem: + +Implemented support for type conversions in the execution of the +ASL Concatenate operator (The second operand is converted to +match the type of the first operand before concatenation.) + +Support for implicit source operand conversion is partially +implemented. The ASL source operand types Integer, Buffer, and +String are freely interchangeable for most ASL operators and are +converted by the interpreter on the fly as required. Implicit +Target operand conversion (where the result is converted to the +target type before storing) is not yet implemented. + +Support for 32-bit and 64-bit BCD integers is implemented. + +Problem fixed where a field read on an aligned field could cause +a read past the end of the field. + +New exception, AE_AML_NO_RETURN_VALUE, is returned when a method +does not return a value, but the caller expects one. (The ASL +compiler flags this as a warning.) + +ASL Compiler: + +Version X2011: +1. Static typechecking of all operands is implemented. This +prevents the use of invalid objects (such as using a Package +where an Integer is required) at compile time instead of at +interpreter run-time. +2. The ASL source line is printed with ALL errors and warnings. +3. Bug fix for source EOF without final linefeed. +4. Debug option is split into a parse trace and a namespace +trace. +5. Namespace output option (-n) includes initial values for +integers and strings. +6. Parse-only option added for quick syntax checking. +7. Compiler checks for duplicate ACPI name declarations + +Version X2012: +1. Relaxed typechecking to allow interchangeability between +strings, integers, and buffers. These types are now converted by +the interpreter at runtime. +2. Compiler reports time taken by each internal subsystem in the +debug output file. + + + ------------------------------------------ +Summary of changes for this label: 12_14_00 + +ASL Compiler: + +This is the first official release of the compiler. Since the +compiler requires elements of the Core Subsystem, this label +synchronizes everything. + +------------------------------------------ +Summary of changes for this label: 12_08_00 + + +Fixed a problem where named references within the ASL definition +of both OperationRegions and CreateXXXFields did not work +properly. The symptom was an AE_AML_OPERAND_TYPE during +initialization of the region/field. This is similar (but not +related internally) to the problem that was fixed in the last +label. + +Implemented both 32-bit and 64-bit support for the BCD ASL +functions ToBCD and FromBCD. + +Updated all legal headers to include "2000" in the copyright +years. + + ------------------------------------------ +Summary of changes for this label: 12_01_00 + +Fixed a problem where method invocations within the ASL +definition of both OperationRegions and CreateXXXFields did not +work properly. The symptom was an AE_AML_OPERAND_TYPE during +initialization of the region/field: + + nsinit-0209: AE_AML_OPERAND_TYPE while getting region arguments +[DEBG] ammonad-0284: Exec_monadic2_r/Not: bad operand(s) +(0x3005) + +Fixed a problem where operators with more than one nested +subexpression would fail. The symptoms were varied, by mostly +AE_AML_OPERAND_TYPE errors. This was actually a rather serious +problem that has gone unnoticed until now. + + Subtract (Add (1,2), Multiply (3,4)) + +Fixed a problem where AcpiGetHandle didn't quite get fixed in the +previous build (The prefix part of a relative path was handled +incorrectly). + +Fixed a problem where Operation Region initialization failed if +the operation region name was a "namepath" instead of a simple +"nameseg". Symptom was an AE_NO_OPERAND error. + +Fixed a problem where an assignment to a local variable via the +indirect RefOf mechanism only worked for the first such +assignment. Subsequent assignments were ignored. + + ------------------------------------------ +Summary of changes for this label: 11_15_00 + +ACPI 2.0 table support with backwards support for ACPI 1.0 and +the 0.71 extensions. Note: although we can read ACPI 2.0 BIOS +tables, the AML interpreter does NOT have support for the new +2.0 ASL grammar terms at this time. + +All ACPI hardware access is via the GAS structures in the ACPI +2.0 FADT. + +All physical memory addresses across all platforms are now 64 +bits wide. Logical address width remains dependent on the +platform (i.e., "void *"). + +AcpiOsMapMemory interface changed to a 64-bit physical address. + +The AML interpreter integer size is now 64 bits, as per the ACPI +2.0 specification. + +For backwards compatibility with ACPI 1.0, ACPI tables with a +revision number less than 2 use 32-bit integers only. + +Fixed a problem where the evaluation of OpRegion operands did not +always resolve them to numbers properly. + +------------------------------------------ +Summary of changes for this label: 10_20_00 + +Fix for CBN_._STA issue. This fix will allow correct access to +CBN_ OpRegions when the _STA returns 0x8. + +Support to convert ACPI constants (Ones, Zeros, One) to actual +values before a package object is returned + +Fix for method call as predicate to if/while construct causing +incorrect if/while behavior + +Fix for Else block package lengths sometimes calculated wrong (if +block > 63 bytes) + +Fix for Processor object length field, was always zero + +Table load abort if FACP sanity check fails + +Fix for problem with Scope(name) if name already exists + +Warning emitted if a named object referenced cannot be found +(resolved) during method execution. + + + + + +------------------------------------------ +Summary of changes for this label: 9_29_00 + +New table initialization interfaces: AcpiInitializeSubsystem no +longer has any parameters AcpiFindRootPointer - Find the RSDP (if +necessary) AcpiLoadTables (RSDP) - load all tables found at RSDP- +>RSDT Obsolete Interfaces AcpiLoadFirmwareTables - replaced by +AcpiLoadTables + +Note: These interface changes require changes to all existing +OSDs + +The PCI_Config default address space handler is always installed +at the root namespace object. + +------------------------------------------- +Summary of changes for this label: 09_15_00 + +The new initialization architecture is implemented. New +interfaces are: AcpiInitializeSubsystem (replaces AcpiInitialize) +AcpiEnableSubsystem Obsolete Interfaces: AcpiLoadNamespace +(Namespace is automatically loaded when a table is loaded) + +The ACPI_OPERAND_OBJECT has been optimized to shrink its size +from 52 bytes to 32 bytes. There is usually one of these for +every namespace object, so the memory savings is significant. + +Implemented just-in-time evaluation of the CreateField operators. + +Bug fixes for IA-64 support have been integrated. + +Additional code review comments have been implemented + +The so-called "third pass parse" has been replaced by a final +walk through the namespace to initialize all operation regions +(address spaces) and fields that have not yet been initialized +during the execution of the various _INI and REG methods. + +New file - namespace/nsinit.c + +------------------------------------------- +Summary of changes for this label: 09_01_00 + +Namespace manager data structures have been reworked to change +the primary object from a table to a single object. This has +resulted in dynamic memory savings of 3X within the namespace +and 2X overall in the ACPI CA subsystem. + +Fixed problem where the call to AcpiEvFindPciRootBuses was +inadvertently left commented out. + +Reduced the warning count when generating the source with the GCC +compiler. + +Revision numbers added to each module header showing the +SourceSafe version of the file. Please refer to this version +number when giving us feedback or comments on individual modules. + +The main object types within the subsystem have been renamed to +clarify their purpose: + +ACPI_INTERNAL_OBJECT -> ACPI_OPERAND_OBJECT +ACPI_GENERIC_OP -> ACPI_PARSE_OBJECT +ACPI_NAME_TABLE_ENTRY -> ACPI_NAMESPACE_NODE + +NOTE: no changes to the initialization sequence are included in +this label. + +------------------------------------------- +Summary of changes for this label: 08_23_00 + +Fixed problem where TerminateControlMethod was being called +multiple times per method + +Fixed debugger problem where single stepping caused a semaphore +to be oversignalled + +Improved performance through additional parse object caching - +added ACPI_EXTENDED_OP type + +------------------------------------------- +Summary of changes for this label: 08_10_00 + +Parser/Interpreter integration: Eliminated the creation of +complete parse trees for ACPI tables and control methods. +Instead, parse subtrees are created and then deleted as soon as +they are processed (Either entered into the namespace or +executed by the interpreter). This reduces the use of dynamic +kernel memory significantly. (about 10X) + +Exception codes broken into classes and renumbered. Be sure to +recompile all code that includes acexcep.h. Hopefully we won't +have to renumber the codes again now that they are split into +classes (environment, programmer, AML code, ACPI table, and +internal). + +Fixed some additional alignment issues in the Resource Manager +subcomponent + +Implemented semaphore tracking in the AcpiExec utility, and fixed +several places where mutexes/semaphores were being unlocked +without a corresponding lock operation. There are no known +semaphore or mutex "leaks" at this time. + +Fixed the case where an ASL Return operator is used to return an +unnamed package. + +------------------------------------------- +Summary of changes for this label: 07_28_00 + +Fixed a problem with the way addresses were calculated in +AcpiAmlReadFieldData() and AcpiAmlWriteFieldData(). This problem +manifested itself when a Field was created with WordAccess or +DwordAccess, but the field unit defined within the Field was +less than a Word or Dword. + +Fixed a problem in AmlDumpOperands() module's loop to pull +operands off of the operand stack to display information. The +problem manifested itself as a TLB error on 64-bit systems when +accessing an operand stack with two or more operands. + +Fixed a problem with the PCI configuration space handlers where +context was getting confused between accesses. This required a +change to the generic address space handler and address space +setup definitions. Handlers now get both a global handler +context (this is the one passed in by the user when executing +AcpiInstallAddressSpaceHandler() and a specific region context +that is unique to each region (For example, the _ADR, _SEG and +_BBN values associated with a specific region). The generic +function definitions have changed to the following: + +typedef ACPI_STATUS (*ADDRESS_SPACE_HANDLER) ( UINT32 Function, +UINT32 Address, UINT32 BitWidth, UINT32 *Value, void +*HandlerContext, // This used to be void *Context void +*RegionContext); // This is an additional parameter + +typedef ACPI_STATUS (*ADDRESS_SPACE_SETUP) ( ACPI_HANDLE +RegionHandle, UINT32 Function, void *HandlerContext, void +**RegionContext); // This used to be **ReturnContext + +------------------------------------------- +Summary of changes for this label: 07_21_00 + +Major file consolidation and rename. All files within the +interpreter have been renamed as well as most header files. +This was done to prevent collisions with existing files in the +host OSs -- filenames such as "config.h" and "global.h" seem to +be quite common. The VC project files have been updated. All +makefiles will require modification. + +The parser/interpreter integration continues in Phase 5 with the +implementation of a complete 2-pass parse (the AML is parsed +twice) for each table; This avoids the construction of a huge +parse tree and therefore reduces the amount of dynamic memory +required by the subsystem. Greater use of the parse object cache +means that performance is unaffected. + +Many comments from the two code reviews have been rolled in. + +The 64-bit alignment support is complete. + +------------------------------------------- +Summary of changes for this label: 06_30_00 + +With a nod and a tip of the hat to the technology of yesteryear, +we've added support in the source code for 80 column output +devices. The code is now mostly constrained to 80 columns or +less to support environments and editors that 1) cannot display +or print more than 80 characters on a single line, and 2) cannot +disable line wrapping. + +A major restructuring of the namespace data structure has been +completed. The result is 1) cleaner and more +understandable/maintainable code, and 2) a significant reduction +in the dynamic memory requirement for each named ACPI object +(almost half). + +------------------------------------------- +Summary of changes for this label: 06_23_00 + +Linux support has been added. In order to obtain approval to get +the ACPI CA subsystem into the Linux kernel, we've had to make +quite a few changes to the base subsystem that will affect all +users (all the changes are generic and OS- independent). The +effects of these global changes have been somewhat far reaching. +Files have been merged and/or renamed and interfaces have been +renamed. The major changes are described below. + +Osd* interfaces renamed to AcpiOs* to eliminate namespace +pollution/confusion within our target kernels. All OSD +interfaces must be modified to match the new naming convention. + +Files merged across the subsystem. A number of the smaller +source and header files have been merged to reduce the file +count and increase the density of the existing files. There are +too many to list here. In general, makefiles that call out +individual files will require rebuilding. + +Interpreter files renamed. All interpreter files now have the +prefix am* instead of ie* and is*. + +Header files renamed: The acapi.h file is now acpixf.h. The +acpiosd.h file is now acpiosxf.h. We are removing references to +the acronym "API" since it is somewhat windowsy. The new name is +"external interface" or xface or xf in the filenames.j + + +All manifest constants have been forced to upper case (some were +mixed case.) Also, the string "ACPI_" has been prepended to +many (not all) of the constants, typedefs, and structs. + +The globals "DebugLevel" and "DebugLayer" have been renamed +"AcpiDbgLevel" and "AcpiDbgLayer" respectively. + +All other globals within the subsystem are now prefixed with +"AcpiGbl_" Internal procedures within the subsystem are now +prefixed with "Acpi" (with only a few exceptions). The original +two-letter abbreviation for the subcomponent remains after +"Acpi" - for example, CmCallocate became AcpiCmCallocate. + +Added a source code translation/conversion utility. Used to +generate the Linux source code, it can be modified to generate +other types of source as well. Can also be used to cleanup +existing source by removing extraneous spaces and blank lines. +Found in tools/acpisrc/* + +OsdUnMapMemory was renamed to OsdUnmapMemory and then +AcpiOsUnmapMemory. (UnMap became Unmap). + +A "MaxUnits" parameter has been added to AcpiOsCreateSemaphore. +When set to one, this indicates that the caller wants to use the +semaphore as a mutex, not a counting semaphore. ACPI CA uses +both types. However, implementers of this call may want to use +different OS primitives depending on the type of semaphore +requested. For example, some operating systems provide separate +"mutex" and "semaphore" interfaces - where the mutex interface +is much faster because it doesn't have all the overhead of a +full semaphore implementation. + +Fixed a deadlock problem where a method that accesses the PCI +address space can block forever if it is the first access to the +space. + +------------------------------------------- +Summary of changes for this label: 06_02_00 + +Support for environments that cannot handle unaligned data +accesses (e.g. firmware and OS environments devoid of alignment +handler technology namely SAL/EFI and the IA-64 Linux kernel) +has been added (via configurable macros) in these three areas: - +Transfer of data from the raw AML byte stream is done via byte +moves instead of word/dword/qword moves. - External objects +are aligned within the user buffer, including package elements +(sub-objects). - Conversion of name strings to UINT32 Acpi Names +is now done byte-wise. + +The Store operator was modified to mimic Microsoft's +implementation when storing to a Buffer Field. + +Added a check of the BM_STS bit before entering C3. + +The methods subdirectory has been obsoleted and removed. A new +file, cmeval.c subsumes the functionality. + +A 16-bit (DOS) version of AcpiExec has been developed. The +makefile is under the acpiexec directory. diff --git a/sys/contrib/dev/acpica/acapps.h b/sys/contrib/dev/acpica/acapps.h new file mode 100644 index 0000000..154593f --- /dev/null +++ b/sys/contrib/dev/acpica/acapps.h @@ -0,0 +1,192 @@ +/****************************************************************************** + * + * Module Name: acapps - common include for ACPI applications/tools + * + *****************************************************************************/ + +/****************************************************************************** + * + * 1.
