  • This change will enable debug object output via a global variable,
    acpi_gbl_enable_aml_debug_object. This will help with remote machine
    debugging. Also, moved all debug object support code to a new
    file, exdebug.c. Entire debug object module can now be
    configured out of the ACPICA build if desired.

  • Repair mechanism was considered too wordy. Now, messages are only
    unconditionally emitted if the return object cannot be repaired.
    Existing messages for successful repairs were converted to
    ACPI_DEBUG_PRINT messages for now. ACPICA BZ 827.

  • 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.

  • acpi_early_init() was changed to over-write the cmdline param,
    making it really inconvenient to set debug flags at boot-time.

    Also,
    This sets the default level to "info", which is what all the ACPI
    drivers use. So to enable messages from drivers, you only have to
    supply the "layer" (a.k.a. "component"). For non-"info" ACPI core
    and ACPI interpreter messages, you have to supply both level and
    layer masks, as before.

  • Removed ACPI_DB_WARN and ACPI_DB_ERROR. These debug levels were
    made obsolete by the ACPI_WARNING and ACPI_ERROR/ACPI_EXCEPTION
    interfaces. Also added ACPI_DB_EVENTS to correspond with the
    existing ACPI_LV_EVENTS.

  • Split ACPI_DEBUG into function trace enabled and not enabled.

    Function trace is most of the ACPI_DEBUG costs, but is
    not much of use for kernel ACPI debugging.

    Size of kernel image increased on test compile:
    + 48k (Full ACPI_DEBUG)
    + 35k (ACPI_DEBUG with function trace compiled out)

    Performance without function trace is also much better.

    Also remove ACPI_LV_DEBUG_OBJECT from default debug level as
    a lot vendors let Store (value, debug) in their code and this
    might confuse users when it pops up in syslog.

  • 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.

  • Implemented the use of a cache object for all internal
    namespace nodes. Since there are about 1000 static nodes
    in a typical system, this will decrease memory use for
    cache implementations that minimize per-allocation overhead
    (such as a slab allocator.)

    Removed the reference count mechanism for internal
    namespace nodes, since it was deemed unnecessary. This
    reduces the size of each namespace node by about 5%-10%
    on all platforms. Nodes are now 20 bytes for the 32-bit
    case, and 32 bytes for the 64-bit case.

    Optimized several internal data structures to reduce
    object size on 64-bit platforms by packing data within
    the 64-bit alignment. This includes the frequently used
    ACPI_OPERAND_OBJECT, of which there can be ~1000 static
    instances corresponding to the namespace objects.

    Added two new strings for the predefined _OSI method:
    "Windows 2001.1 SP1" and "Windows 2006".

    Split the allocation tracking mechanism out to a separate
    file, from utalloc.c to uttrack.c. This mechanism appears
    to be only useful for application-level code. Kernels may
    wish to not include uttrack.c in distributions.

    Removed all remnants of the obsolete ACPI_REPORT_* macros
    and the associated code. (These macros have been replaced
    by the ACPI_ERROR and ACPI_WARNING macros.)

  • 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.

  • 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!
