  • Converted the locking mutex used for the ACPI hardware
    to a spinlock. This change should eliminate all problems
    caused by attempting to acquire a semaphore at interrupt
    level, and it means that all ACPICA external interfaces
    that directly access the ACPI hardware can be safely
    called from interrupt level.

    Fixed a regression introduced in 20060526 where the ACPI
    device initialization could be prematurely aborted with
    an AE_NOT_FOUND if a device did not have an optional
    _INI method.

    Fixed an IndexField issue where a write to the Data
    Register should be limited in size to the AccessSize
    (width) of the IndexField itself. (BZ 433, Fiodor Suietov)

    Fixed problem reports (Valery Podrezov) integrated: - Allow
    store of ThermalZone objects to Debug object.

    Fixed problem reports (Fiodor Suietov) integrated: -
    acpi_get_table_header() doesn't handle multiple instances
    correctly (BZ 364)

    Removed four global mutexes that were obsolete and were
    no longer being used.

  • 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.

  • Removed a couple of extraneous ACPI_ERROR messages that
    appeared during normal execution. These became apparent
    after the conversion from ACPI_DEBUG_PRINT.

    Fixed a problem where the CreateField operator could hang
    if the BitIndex or NumBits parameter referred to a named
    object. From Valery Podrezov.

  • 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. (With assistance
    from Thomas Renninger)

  • 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.

  • 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!
