  • We have ported Rafael's major GPE changes
    (ACPI: Use GPE reference counting to support shared GPEs) into ACPICA code base.
    But the port and Rafael's original patch have some differences, so we made
    below patch to make linux GPE code consistent with ACPICA code base.

    Most changes are about comments and coding styles.
    Other noticeable changes are based on:

    Rafael: Reduce code duplication related to GPE lookup
    https://patchwork.kernel.org/patch/86237/

    Rafael: Always use the same lock for GPE locking
    https://patchwork.kernel.org/patch/90471/

    A new field gpe_count in struct acpi_gpe_block_info to record the number
    of individual GPEs in block.

    Rename acpi_ev_save_method_info to acpi_ev_match_gpe_method.

  • Now return AE_BAD_PARAMETER if the input register pointer is
    null, and AE_BAD_ADDRESS if the register has an address of zero.
    Previously, these cases simply returned AE_OK. For optional
    registers such as PM1B status/enable/control, the caller should
    check for a valid register address before calling. ACPICA BZ 748.

  • acpi.h now includes only the "public" acpica headers. All other
    acpica headers are "private" and should not be included by acpica
    users. One new file, accommon.h is used to include the commonly
    used private headers for acpica code generation. Future plans
    are to move all private headers to a new subdirectory.

  • Add a loop counter to force exit from AML While loops if the
    count becomes too large. This can occur in poorly written AML
    when the hardware does not respond within a while loop and the
    loop does not implement a timeout. The maximum loop count is
    configurable. A new exception code is returned when a loop is
    broken, AE_AML_INFINITE_LOOP. Bob Moore, Alexey Starikovskiy.

  • 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.

  • Added 2006 copyright.

    At SuSE's suggestion, enabled all error messages
    without enabling function tracing, ie with CONFIG_ACPI_DEBUG=n

    Replaced all instances of the ACPI_DEBUG_PRINT macro invoked at
    the ACPI_DB_ERROR and ACPI_DB_WARN debug levels with
    the ACPI_REPORT_ERROR and ACPI_REPORT_WARNING macros,
    respectively. This preserves all error and warning messages
    in the non-debug version of the ACPICA code (this has been
    referred to as the "debug lite" option.) Over 200 cases
    were converted to create a total of over 380 error/warning
    messages across the ACPICA code. This increases the code
    and data size of the default non-debug version by about 13K.
    Added ACPI_NO_ERROR_MESSAGES flag to enable deleting all messages.
    The size of the debug version remains about the same.

  • The use of the CPU stack in the debug version of the
    subsystem has been considerably reduced. Previously, a
    debug structure was declared in every function that used
    the debug macros. This structure has been removed in
    favor of declaring the individual elements as parameters
    to the debug functions. This reduces the cumulative stack
    use during nested execution of ACPI function calls at the
    cost of a small increase in the code size of the debug
    version of the subsystem. With assistance from Alexey
    Starikovskiy and Len Brown.

    Added the ACPI_GET_FUNCTION_NAME macro to enable the
    compiler-dependent headers to define a macro that will
    return the current function name at runtime (such as
    __FUNCTION__ or _func_, etc.) The function name is used
    by the debug trace output. If ACPI_GET_FUNCTION_NAME
    is not defined in the compiler-dependent header, the
    function name is saved on the CPU stack (one pointer per
    function.) This mechanism is used because apparently there
    exists no standard ANSI-C defined macro that that returns
    the function name.

    Alexey Starikovskiy redesigned and reimplemented the
    "Owner ID" mechanism used to track namespace objects
    created/deleted by ACPI tables and control method
    execution. A bitmap is now used to allocate and free the
    IDs, thus solving the wraparound problem present in the
    previous implementation. The size of the namespace node
    descriptor was reduced by 2 bytes as a result.

    Removed the UINT32_BIT and UINT16_BIT types that were used
    for the bitfield flag definitions within the headers for
    the predefined ACPI tables. These have been replaced by
    UINT8_BIT in order to increase the code portability of
    the subsystem. If the use of UINT8 remains a problem,
    we may be forced to eliminate bitfields entirely because
    of a lack of portability.

    Alexey Starikovksiy enhanced the performance of
    acpi_ut_update_object_reference. This is a frequently used
    function and this improvement increases the performance
    of the entire subsystem.

    Alexey Starikovskiy fixed several possible memory leaks
    and the inverse - premature object deletion.

  • Fixed three cases in the interpreter where an "index"
    argument to an ASL function was still (internally) 32
    bits instead of the required 64 bits. This was the Index
    argument to the Index, Mid, and Match operators.

    The "strupr" function is now permanently local
    (acpi_ut_strupr), since this is not a POSIX-defined
    function and not present in most kernel-level C
    libraries. References to the C library strupr function
    have been removed from the headers.

    Completed the deployment of static
    functions/prototypes. All prototypes with the static
    attribute have been moved from the headers to the owning
    C file.

    ACPICA 20050329 from Bob Moore

    An error is now generated if an attempt is made to create
    a Buffer Field of length zero (A CreateField with a length
    operand of zero.)

    The interpreter now issues a warning whenever executable
    code at the module level is detected during ACPI table
    load. This will give some idea of the prevalence of this
    type of code.

    Implemented support for references to named objects (other
    than control methods) within package objects.

    Enhanced package object output for the debug
    object. Package objects are now completely dumped, showing
    all elements.

    Enhanced miscellaneous object output for the debug
    object. Any object can now be written to the debug object
    (for example, a device object can be written, and the type
    of the object will be displayed.)

    The "static" qualifier has been added to all local
    functions across the core subsystem.

    The number of "long" lines (> 80 chars) within the source
    has been significantly reduced, by about 1/3.

    Cleaned up all header files to ensure that all CA/iASL
    functions are prototyped (even static functions) and the
    formatting is consistent.

    Two new header files have been added, acopcode.h and
    acnames.h.

    Removed several obsolete functions that were no longer
    used.

  • Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
