ACPI: ACPICA 20060526 Restructured, flattened, and simplified the internal interfaces for namespace object evaluation - resulting in smaller code, less CPU stack use, and fewer interfaces. (With assistance from Mikhail Kouzmich) Fixed a problem with the CopyObject operator where the first parameter was not typed correctly for the parser, interpreter, compiler, and disassembler. Caused various errors and unexpected behavior. Fixed a problem where a ShiftLeft or ShiftRight of more than 64 bits produced incorrect results with some C compilers. Since the behavior of C compilers when the shift value is larger than the datatype width is apparently not well defined, the interpreter now detects this condition and simply returns zero as expected in all such cases. (BZ 395) Fixed problem reports (Valery Podrezov) integrated: - Update String-to-Integer conversion to match ACPI 3.0A spec http://bugzilla.kernel.org/show_bug.cgi?id=5329 Allow interpreter to handle nested method declarations http://bugzilla.kernel.org/show_bug.cgi?id=5361 Fixed problem reports (Fiodor Suietov) integrated: - acpi_terminate() doesn't free debug memory allocation list objects (BZ 355) - After Core Subsystem shutdown, acpi_subsystem_status() returns AE_OK (BZ 356) - acpi_os_unmap_memory() for RSDP can be invoked inconsistently (BZ 357) - Resource Manager should return AE_TYPE for non-device objects (BZ 358) - Incomplete cleanup branch in AcpiNsEvaluateRelative (BZ 359) - Use acpi_os_free() instead of ACPI_FREE in acpi_rs_set_srs_method_data (BZ 360) - Incomplete cleanup branch in acpi_ps_parse_aml (BZ 361) - Incomplete cleanup branch in acpi_ds_delete_walk_state (BZ 362) - acpi_get_table_header returns AE_NO_ACPI_TABLES until DSDT is loaded (BZ 365) - Status of the Global Initialization Handler call not used (BZ 366) - Incorrect object parameter to Global Initialization Handler (BZ 367) Signed-off-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

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.)

ACPICA: Cleanup indentation to reduce differences between Linux and ACPICA. This is a cosmetic patch only. Comparison of the resulting binary showed only line number differences. This patch does not affect the generation of the Linux binary. This patch decreases 210 lines of 20121018 divergence.diff. The ACPICA source codes uses a totally different indentation style from the Linux to be compatible with other users (operating systems or BIOS). Indentation differences are critical to the release automation. There are two causes related to the "indentation" that are affecting the release automation: 1. The ACPICA -> Linux release process is: ACPICA source -- acpisrc - hierarchy - indent -> linuxized ACPICA source -- diff -> linuxized ACPICA patch (x) -- human intervention -> linuxized ACPICA patch (o) Where 'x' means "cannot be directly applied to the Linux" 'o' means "can be directly applied to the Linux" Different "indent" version or "indent" options used in the "indent" step will lead to different divergences. The version of "indent" used for the current release process is: GNU indent 2.2.11 The options of "indent" used for the current release process is: -npro -kr -i8 -ts8 -sob -l80 -ss -ncs 2. Manual indentation prettifying work in the Linux side will also harm the automatically generated linuxized ACPICA patches, making them impossible to apply directly. This patch fixes source code differences caused by the two causes so that the "human intervention" can be reduced in the future. Signed-off-by: Lv Zheng <lv.zheng@intel.com> Signed-off-by: Rafael J.

#ifndef ACPI_USE_ALTERNATE_PROTOTYPE_acpi_os_signal_semaphore
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.)

ACPICA 20050617-0624 from Bob Moore <robert.moore@intel.com> ACPICA 20050617: Moved the object cache operations into the OS interface layer (OSL) to allow the host OS to handle these operations if desired (for example, the Linux OSL will invoke the slab allocator). This support is optional; the compile time define ACPI_USE_LOCAL_CACHE may be used to utilize the original cache code in the ACPI CA core. The new OSL interfaces are shown below. See utalloc.c for an example implementation, and acpiosxf.h for the exact interface definitions. Thanks to Alexey Starikovskiy. acpi_os_create_cache acpi_os_delete_cache acpi_os_purge_cache acpi_os_acquire_object acpi_os_release_object Modified the interfaces to acpi_os_acquire_lock and acpi_os_release_lock to return and restore a flags parameter. This fits better with many OS lock models. Note: the current execution state (interrupt handler or not) is no longer passed to these interfaces. If necessary, the OSL must determine this state by itself, a simple and fast operation. Thanks to Alexey Starikovskiy. Fixed a problem in the ACPI table handling where a valid XSDT was assumed present if the revision of the RSDP was 2 or greater. According to the ACPI specification, the XSDT is optional in all cases, and the table manager therefore now checks for both an RSDP >=2 and a valid XSDT pointer. Otherwise, the RSDT pointer is used. Some ACPI 2.0 compliant BIOSs contain only the RSDT. Fixed an interpreter problem with the Mid() operator in the case of an input string where the resulting output string is of zero length. It now correctly returns a valid, null terminated string object instead of a string object with a null pointer. Fixed a problem with the control method argument handling to allow a store to an Arg object that already contains an object of type Device. The Device object is now correctly overwritten. Previously, an error was returned. ACPICA 20050624: Modified the new OSL cache interfaces to use ACPI_CACHE_T as the type for the host-defined cache object. This allows the OSL implementation to define and type this object in any manner desired, simplifying the OSL implementation. For example, ACPI_CACHE_T is defined as kmem_cache_t for Linux, and should be defined in the OS-specific header file for other operating systems as required. Changed the interface to AcpiOsAcquireObject to directly return the requested object as the function return (instead of ACPI_STATUS.) This change was made for performance reasons, since this is the purpose of the interface in the first place. acpi_os_acquire_object is now similar to the acpi_os_allocate interface. Thanks to Alexey Starikovskiy. Modified the initialization sequence in acpi_initialize_subsystem to call the OSL interface acpi_osl_initialize first, before any local initialization. This change was required because the global initialization now calls OSL interfaces. Restructured the code base to split some files because of size and/or because the code logically belonged in a separate file.

Fixed a problem in the ACPI table handling where a valid XSDT was assumed present if the revision of the RSDP was 2 or greater. According to the ACPI specification, the XSDT is optional in all cases, and the table manager therefore now checks for both an RSDP >=2 and a valid XSDT pointer. Otherwise, the RSDT pointer is used. Some ACPI 2.0 compliant BIOSs contain only the RSDT. Fixed an interpreter problem with the Mid() operator in the case of an input string where the resulting output string is of zero length. It now correctly returns a valid, null terminated string object instead of a string object with a null pointer. Fixed a problem with the control method argument handling to allow a store to an Arg object that already contains an object of type Device. The Device object is now correctly overwritten. Previously, an error was returned. ACPICA 20050624: Modified the new OSL cache interfaces to use ACPI_CACHE_T as the type for the host-defined cache object. This allows the OSL implementation to define and type this object in any manner desired, simplifying the OSL implementation. For example, ACPI_CACHE_T is defined as kmem_cache_t for Linux, and should be defined in the OS-specific header file for other operating systems as required. Changed the interface to AcpiOsAcquireObject to directly return the requested object as the function return (instead of ACPI_STATUS.) This change was made for performance reasons, since this is the purpose of the interface in the first place. acpi_os_acquire_object is now similar to the acpi_os_allocate interface. Thanks to Alexey Starikovskiy. Modified the initialization sequence in acpi_initialize_subsystem to call the OSL interface acpi_osl_initialize first, before any local initialization. This change was required because the global initialization now calls OSL interfaces. Restructured the code base to split some files because of size and/or because the code logically belonged in a separate file. New files are listed below. utilities/utcache.c /* Local cache interfaces */ utilities/utmutex.c /* Local mutex support */ utilities/utstate.c /* State object support */ parser/psloop.c /* Main AML parse loop */ Signed-off-by: Len Brown <len.brown@intel.com>

ACPICA 20050617-0624 from Bob Moore <robert.moore@intel.com> ACPICA 20050617: Moved the object cache operations into the OS interface layer (OSL) to allow the host OS to handle these operations if desired (for example, the Linux OSL will invoke the slab allocator). This support is optional; the compile time define ACPI_USE_LOCAL_CACHE may be used to utilize the original cache code in the ACPI CA core. The new OSL interfaces are shown below.
