* Architecture-specific ACPICA Subsystem Data Types
*
* The goal of these types is to provide source code portability across
* 16-bit, 32-bit, and 64-bit targets.
*
* 1) The following types are of fixed size for all targets (16/32/64):
*
* BOOLEAN Logical boolean
*
* UINT8 8-bit (1 byte) unsigned value
* UINT16 16-bit (2 byte) unsigned value
* UINT32 32-bit (4 byte) unsigned value
* UINT64 64-bit (8 byte) unsigned value
*
* INT16 16-bit (2 byte) signed value
* INT32 32-bit (4 byte) signed value
* INT64 64-bit (8 byte) signed value
*
* COMPILER_DEPENDENT_UINT64/INT64 - These types are defined in the
* compiler-dependent header(s) and were introduced because there is no common
* 64-bit integer type across the various compilation models, as shown in
* the table below.
*
* Datatype LP64 ILP64 LLP64 ILP32 LP32 16bit
* char 8 8 8 8 8 8
* short 16 16 16 16 16 16
* _int32 32
* int 32 64 32 32 16 16
* long 64 64 32 32 32 32
* long long 64 64
* pointer 64 64 64 32 32 32
*
* Note: ILP64 and LP32 are currently not supported.
*
*
* 2) These types represent the native word size of the target mode of the
* processor, and may be 16-bit, 32-bit, or 64-bit as required. They are
* usually used for memory allocation, efficient loop counters, and array
* indexes. The types are similar to the size_t type in the C library and are
* required because there is no C type that consistently represents the native
* data width.
*
* ACPI_SIZE 16/32/64-bit unsigned value
* ACPI_NATIVE_UINT 16/32/64-bit unsigned value
* ACPI_NATIVE_INT 16/32/64-bit signed value
*

[ACPI] ACPICA 20060127 Implemented support in the Resource Manager to allow unresolved namestring references within resource package objects for the _PRT method. This support is in addition to the previously implemented unresolved reference support within the AML parser. If the interpreter slack mode is enabled (true on Linux unless acpi=strict), these unresolved references will be passed through to the caller as a NULL package entry. http://bugzilla.kernel.org/show_bug.cgi?id=5741 Implemented and deployed new macros and functions for error and warning messages across the subsystem. These macros are simpler and generate less code than their predecessors. The new macros ACPI_ERROR, ACPI_EXCEPTION, ACPI_WARNING, and ACPI_INFO replace the ACPI_REPORT_* macros. Implemented the acpi_cpu_flags type to simplify host OS integration of the Acquire/Release Lock OSL interfaces. Suggested by Steven Rostedt and Andrew Morton. Fixed a problem where Alias ASL operators are sometimes not correctly resolved. causing AE_AML_INTERNAL http://bugzilla.kernel.org/show_bug.cgi?id=5189 http://bugzilla.kernel.org/show_bug.cgi?id=5674 Fixed several problems with the implementation of the ConcatenateResTemplate ASL operator. As per the ACPI specification, zero length buffers are now treated as a single EndTag. One-length buffers always cause a fatal exception. Non-zero length buffers that do not end with a full 2-byte EndTag cause a fatal exception. Fixed a possible structure overwrite in the AcpiGetObjectInfo external interface.

ACPI: ACPICA 20060623 Implemented a new acpi_spinlock type for the OSL lock interfaces. This allows the type to be customized to the host OS for improved efficiency (since a spinlock is usually a very small object.) Implemented support for "ignored" bits in the ACPI registers. According to the ACPI specification, these bits should be preserved when writing the registers via a read/modify/write cycle. There are 3 bits preserved in this manner: PM1_CONTROL[0] (SCI_EN), PM1_CONTROL[9], and PM1_STATUS[11]. http://bugzilla.kernel.org/show_bug.cgi?id=3691 Implemented the initial deployment of new OSL mutex interfaces. Since some host operating systems have separate mutex and semaphore objects, this feature was requested. The base code now uses mutexes (and the new mutex interfaces) wherever a binary semaphore was used previously. However, for the current release, the mutex interfaces are defined as macros to map them to the existing semaphore interfaces. Fixed several problems with the support for the control method SyncLevel parameter. The SyncLevel now works according to the ACPI specification and in concert with the Mutex SyncLevel parameter, since the current SyncLevel is a property of the executing thread. Mutual exclusion for control methods is now implemented with a mutex instead of a semaphore. Fixed three instances of the use of the C shift operator in the bitfield support code (exfldio.c) to avoid the use of a shift value larger than the target data width. The behavior of C compilers is undefined in this case and can cause unpredictable results, and therefore the case must be detected and avoided. (Fiodor Suietov) Added an info message whenever an SSDT or OEM table is loaded dynamically via the Load() or LoadTable() ASL operators. This should improve debugging capability since it will show exactly what tables have been loaded (beyond the tables present in the RSDT/XSDT.)

These macros are simpler and generate less code than their predecessors. The new macros ACPI_ERROR, ACPI_EXCEPTION, ACPI_WARNING, and ACPI_INFO replace the ACPI_REPORT_* macros. Implemented the acpi_cpu_flags type to simplify host OS integration of the Acquire/Release Lock OSL interfaces. Suggested by Steven Rostedt and Andrew Morton. Fixed a problem where Alias ASL operators are sometimes not correctly resolved. causing AE_AML_INTERNAL http://bugzilla.kernel.org/show_bug.cgi?id=5189 http://bugzilla.kernel.org/show_bug.cgi?id=5674 Fixed several problems with the implementation of the ConcatenateResTemplate ASL operator. As per the ACPI specification, zero length buffers are now treated as a single EndTag. One-length buffers always cause a fatal exception. Non-zero length buffers that do not end with a full 2-byte EndTag cause a fatal exception. Fixed a possible structure overwrite in the AcpiGetObjectInfo external interface.

ACPI: ACPICA 20060623 Implemented a new acpi_spinlock type for the OSL lock interfaces. This allows the type to be customized to the host OS for improved efficiency (since a spinlock is usually a very small object.) Implemented support for "ignored" bits in the ACPI registers. According to the ACPI specification, these bits should be preserved when writing the registers via a read/modify/write cycle. There are 3 bits preserved in this manner: PM1_CONTROL[0] (SCI_EN), PM1_CONTROL[9], and PM1_STATUS[11]. http://bugzilla.kernel.org/show_bug.cgi?id=3691 Implemented the initial deployment of new OSL mutex interfaces. Since some host operating systems have separate mutex and semaphore objects, this feature was requested. The base code now uses mutexes (and the new mutex interfaces) wherever a binary semaphore was used previously. However, for the current release, the mutex interfaces are defined as macros to map them to the existing semaphore interfaces. Fixed several problems with the support for the control method SyncLevel parameter. The SyncLevel now works according to the ACPI specification and in concert with the Mutex SyncLevel parameter, since the current SyncLevel is a property of the executing thread. Mutual exclusion for control methods is now implemented with a mutex instead of a semaphore. Fixed three instances of the use of the C shift operator in the bitfield support code (exfldio.c) to avoid the use of a shift value larger than the target data width. The behavior of C compilers is undefined in this case and can cause unpredictable results, and therefore the case must be detected and avoided. (Fiodor Suietov) Added an info message whenever an SSDT or OEM table is loaded dynamically via the Load() or LoadTable() ASL operators. This should improve debugging capability since it will show exactly what tables have been loaded (beyond the tables present in the RSDT/XSDT.)

[ACPI] ACPICA 20051117 Fixed a problem in the AML parser where the method thread count could be decremented below zero if any errors occurred during the method parse phase. This should eliminate AE_AML_METHOD_LIMIT exceptions seen on some machines. This also fixed a related regression with the mechanism that detects and corrects methods that cannot properly handle reentrancy (related to the deployment of the new OwnerId mechanism.) Eliminated the pre-parsing of control methods (to detect errors) during table load. Related to the problem above, this was causing unwind issues if any errors occurred during the parse, and it seemed to be overkill. A table load should not be aborted if there are problems with any single control method, thus rendering this feature rather pointless. Fixed a problem with the new table-driven resource manager where an internal buffer overflow could occur for small resource templates. Implemented a new external interface, acpi_get_vendor_resource() This interface will find and return a vendor-defined resource descriptor within a _CRS or _PRS method via an ACPI 3.0 UUID match. (from Bjorn Helgaas) Removed the length limit (200) on string objects as per the upcoming ACPI 3.0A specification. This affects the following areas of the interpreter: 1) any implicit conversion of a Buffer to a String, 2) a String object result of the ASL Concatentate operator, 3) the String object result of the ASL ToString operator.

ACPI: ACPICA 20060421 Removed a device initialization optimization introduced in 20051216 where the _STA method was not run unless an _INI was also present for the same device. This optimization could cause problems because it could allow _INI methods to be run within a not-present device subtree (If a not-present device had no _INI, _STA would not be run, the not-present status would not be discovered, and the children of the device would be incorrectly traversed.) Implemented a new _STA optimization where namespace subtrees that do not contain _INI are identified and ignored during device initialization. Selectively running _STA can significantly improve boot time on large machines (with assistance from Len Brown.) Implemented support for the device initialization case where the returned _STA flags indicate a device not-present but functioning. In this case, _INI is not run, but the device children are examined for presence, as per the ACPI specification. Implemented an additional change to the IndexField support in order to conform to MS behavior. The value written to the Index Register is not simply a byte offset, it is a byte offset in units of the access width of the parent Index Field. (Fiodor Suietov) Defined and deployed a new OSL interface, acpi_os_validate_address(). This interface is called during the creation of all AML operation regions, and allows the host OS to exert control over what addresses it will allow the AML code to access. Operation Regions whose addresses are disallowed will cause a runtime exception when they are actually accessed (will not affect or abort table loading.) Defined and deployed a new OSL interface, acpi_os_validate_interface(). This interface allows the host OS to match the various "optional" interface/behavior strings for the _OSI predefined control method as appropriate (with assistance from Bjorn Helgaas.) Restructured and corrected various problems in the exception handling code paths within DsCallControlMethod and DsTerminateControlMethod in dsmethod (with assistance from Takayoshi Kochi.) Modified the Linux source converter to ignore quoted string literals while converting identifiers from mixed to lower case. This will correct problems with the disassembler and other areas where such strings must not be modified. The ACPI_FUNCTION_* macros no longer require quotes around the function name. This allows the Linux source converter to convert the names, now that the converter ignores quoted strings.

[ACPI] ACPICA 20051117 Fixed a problem in the AML parser where the method thread count could be decremented below zero if any errors occurred during the method parse phase. This should eliminate AE_AML_METHOD_LIMIT exceptions seen on some machines. This also fixed a related regression with the mechanism that detects and corrects methods that cannot properly handle reentrancy (related to the deployment of the new OwnerId mechanism.) Eliminated the pre-parsing of control methods (to detect errors) during table load. Related to the problem above, this was causing unwind issues if any errors occurred during the parse, and it seemed to be overkill. A table load should not be aborted if there are problems with any single control method, thus rendering this feature rather pointless. Fixed a problem with the new table-driven resource manager where an internal buffer overflow could occur for small resource templates. Implemented a new external interface, acpi_get_vendor_resource() This interface will find and return a vendor-defined resource descriptor within a _CRS or _PRS method via an ACPI 3.0 UUID match. (from Bjorn Helgaas) Removed the length limit (200) on string objects as per the upcoming ACPI 3.0A specification. This affects the following areas of the interpreter: 1) any implicit conversion of a Buffer to a String, 2) a String object result of the ASL Concatentate operator, 3) the String object result of the ASL ToString operator.

[ACPI] ACPICA 20050930 Completed a major overhaul of the Resource Manager code - specifically, optimizations in the area of the AML/internal resource conversion code. The code has been optimized to simplify and eliminate duplicated code, CPU stack use has been decreased by optimizing function parameters and local variables, and naming conventions across the manager have been standardized for clarity and ease of maintenance (this includes function, parameter, variable, and struct/typedef names.) All Resource Manager dispatch and information tables have been moved to a single location for clarity and ease of maintenance. One new file was created, named "rsinfo.c". The ACPI return macros (return_ACPI_STATUS, etc.) have been modified to guarantee that the argument is not evaluated twice, making them less prone to macro side-effects. However, since there exists the possibility of additional stack use if a particular compiler cannot optimize them (such as in the debug generation case), the original macros are optionally available. Note that some invocations of the return_VALUE macro may now cause size mismatch warnings; the return_UINT8 and return_UINT32 macros are provided to eliminate these. (From Randy Dunlap) Implemented a new mechanism to enable debug tracing for individual control methods. A new external interface, acpi_debug_trace(), is provided to enable this mechanism. The intent is to allow the host OS to easily enable and disable tracing for problematic control methods. This interface can be easily exposed to a user or debugger interface if desired. See the file psxface.c for details. acpi_ut_callocate() will now return a valid pointer if a length of zero is specified - a length of one is used and a warning is issued.

All Resource Manager dispatch and information tables have been moved to a single location for clarity and ease of maintenance. One new file was created, named "rsinfo.c". The ACPI return macros (return_ACPI_STATUS, etc.) have been modified to guarantee that the argument is not evaluated twice, making them less prone to macro side-effects. However, since there exists the possibility of additional stack use if a particular compiler cannot optimize them (such as in the debug generation case), the original macros are optionally available. Note that some invocations of the return_VALUE macro may now cause size mismatch warnings; the return_UINT8 and return_UINT32 macros are provided to eliminate these. (From Randy Dunlap) Implemented a new mechanism to enable debug tracing for individual control methods. A new external interface, acpi_debug_trace(), is provided to enable this mechanism. The intent is to allow the host OS to easily enable and disable tracing for problematic control methods. This interface can be easily exposed to a user or debugger interface if desired. See the file psxface.c for details. acpi_ut_callocate() will now return a valid pointer if a length of zero is specified - a length of one is used and a warning is issued.

[ACPI] ACPICA 20051117 Fixed a problem in the AML parser where the method thread count could be decremented below zero if any errors occurred during the method parse phase. This should eliminate AE_AML_METHOD_LIMIT exceptions seen on some machines. This also fixed a related regression with the mechanism that detects and corrects methods that cannot properly handle reentrancy (related to the deployment of the new OwnerId mechanism.) Eliminated the pre-parsing of control methods (to detect errors) during table load. Related to the problem above, this was causing unwind issues if any errors occurred during the parse, and it seemed to be overkill. A table load should not be aborted if there are problems with any single control method, thus rendering this feature rather pointless. Fixed a problem with the new table-driven resource manager where an internal buffer overflow could occur for small resource templates. Implemented a new external interface, acpi_get_vendor_resource() This interface will find and return a vendor-defined resource descriptor within a _CRS or _PRS method via an ACPI 3.0 UUID match. (from Bjorn Helgaas) Removed the length limit (200) on string objects as per the upcoming ACPI 3.0A specification. This affects the following areas of the interpreter: 1) any implicit conversion of a Buffer to a String, 2) a String object result of the ASL Concatentate operator, 3) the String object result of the ASL ToString operator.
