    ACPICA commit b2294cae776f5a66a7697414b21949d307e6856f

    This patch removes unwanted spaces for typedef. This solution doesn't cover
    function types.

    Note that the linuxize result of this commit is very giant and should have
    many conflicts against the current Linux upstream. Thus it is required to
    modify the linuxize result of this commit and the commits around it
    manually in order to have them merged to the Linux upstream. Since this is
    very costy, we should do this only once, and if we can't ensure to do this
    only once, we need to revert the Linux code to the wrong indentation result
    before merging the linuxize result of this commit. Lv Zheng.

  • ab6c57332   ACPICA: Executer: Add interpreter tracing mode for method tracing facility ... Browse Code »

    ACPICA commit 07fffd02607685b655ed92ee15c160e6a810b60b

    The acpi_debug_trace() is the mechanism known as ACPI method tracing that is
    used by Linux as ACPICA debugging message reducer. This facility can be
    controlled through Linux ACPI subsystem - /sys/module/acpi/parameters.
    This facility requires CONFIG_ACPI_DEBUG to be enabled to see ACPICA trace
    logs in the kernel dmesg output.

    This patch enhances acpi_debug_trace() to make it not only a message reducer,
    but a real tracer to trace AML interpreter execution. Note that in addition
    to the AML tracer enabling, this patch also updates the facility with the
    following enhancements:
    1. Allow a full path to be specified by the acpi_debug_trace() API.
    2. Allow any method rather than just the entrance of acpi_evaluate_object()
    to be traced.
    3. All interpreter ACPI_LV_TRACE_POINT messages are collected for
    ACPI_EXECUTER layer.

    The Makefile of drivers/acpi/acpica is also updated to include exdebug.o
    and the duplicated stubs are removed after that.

    Note that since this patch has enhanced the method tracing facility, Linux
    need also be updated after applying this patch. Lv Zheng.

  • 62eb935b7   ACPICA: Dispatcher: Cleanup union acpi_operand_object's AML address assignments ... Browse Code »

    ACPICA commit afb52611dbe7403551f93504d3798534f5c343f4

    This patch cleans up the code of assigning the AML address to the
    union acpi_operand_object.

    The idea behind this cleanup is:
    The AML address of the union acpi_operand_object should always be determined at
    the point where the object is encountered. It should be started from the
    first byte of the object. For example, the opcode of the object, the name
    string of the user_term object, or the first byte of the packaged object
    (where a pkg_length is prefixed). So it's not cleaner to have it assigned
    here and there in the entire ACPICA source tree.

    There are some special cases for the internal opcodes, before cleaning up
    the internal opcodes, we should also determine the rules for the AML
    addresses of the internal opcodes:
    1. INT_NAMEPATH_OP: the address of the first byte for the name_string.
    2. INT_METHODCALL_OP: the address of the first byte for the name_string.
    3. INT_BYTELIST_OP: the address of the first byte for the byte_data list.
    4. INT_EVAL_SUBTREE_OP: the address of the first byte for the
    Region/Package/Buffer/bank_field/Field arguments.
    5. INT_NAMEDFIELD_OP: the address to the name_seg.
    6. INT_RESERVEDFIELD_OP: the address to the 0x00 prefix.
    7. INT_ACCESSFIELD_OP: the address to the 0x01 prefix.
    8. INT_CONNECTION_OP: the address to the 0x02 prefix.
    9: INT_EXTACCESSFIELD_OP: the address to the 0x03 prefix.
    10.INT_RETURN_VALUE_OP: the address of the replaced operand.
    11.computational_data: the address to the
    Byte/Word/Dword/Qword/string_prefix.

    Before cleaning up the internal root scope of the aml_walk, turning it into
    the term_list, we need to remember the aml_start address as the "Aml"
    attribute for the union acpi_operand_object created by acpi_ps_create_scope_op().

    Finally, we can delete some redundant AML address assignment in psloop.c.

    It is reported by kernel build test systems that all ACPICA source

  • 262948428   ACPICA: Fix issues/fault with automatic "serialized" method support ... Browse Code »

    History: This support changes a method to "serialized" on the fly if the
    method generates an AE_ALREADY_EXISTS error, indicating the possibility
    that it cannot handle reentrancy.

    This fix repairs a couple of issues seen in the field, especially on
    machines with many cores.

    1) Delete method children only upon the exit of the last thread, so
    as to not delete objects out from under running threads.

    2) Set the "serialized" bit for the method only upon the exit of the
    last thread, so as to not cause deadlock when running threads attempt
    to exit.

    3) Cleanup the use of the AML "MethodFlags" and internal method flags
    so that there is no longer any confustion between the two.

    Optionally copy the entire DSDT to local memory (instead of
    simply mapping it.) There are some BIOSs that corrupt or replace
    the original DSDT, creating the need for this option. Default is
    FALSE, do not copy the DSDT.

    This change adds support to detect a DSDT that has been corrupted

    typically catastrophic for the system, but has been seen on

    Add limited support for executable AML code that exists outside
    of any control method. This type of code has been illegal since
    ACPI 2.0. The code must exist in an If/Else/While block. All AML
    tables are supported, including tables that are dynamically loaded.
