    Introduce module parameter acpi.aml_debug_output.

    With acpi.aml_debug_output set, we can get AML debug object output
    (Store (AAA, Debug)), even with CONFIG_ACPI_DEBUG cleared.

    Together with the runtime custom method mechanism,
    we can debug AML code problems without rebuilding the kernel.

    Some hardware error injection needs parameters, for example, it is
    useful to specify memory address and memory address mask for memory
    errors.

    Some BIOSes allow parameters to be specified via an unpublished
    extension. This patch adds support to it. The parameters will be
    ignored on machines without necessary BIOS support.

  • a1a541d86   ACPI: support customizing ACPI control methods at runtime ... Browse Code »

    Introduce a new debugfs I/F (/sys/kernel/debug/acpi/custom_method) for ACPI,
    which can be used to customize the ACPI control methods at runtime.

    We can use this to debug the AML code level bugs instead of overriding the
    whole DSDT table, without rebuilding/rebooting kernel any more.

    Detailed description about how to use this debugfs I/F is stated in
    Documentation/acpi/method-customizing.txt

  • a0d84a92d   ACPI: update debug parameter documentation ... Browse Code »

    Reformat acpi.debug_layer and acpi.debug_level documentation so it's
    more readable, add some clues about how to figure out the mask bits that
    enable a specific ACPI_DEBUG_PRINT statement, and include some useful
    examples.

    Move the list of masks to Documentation/acpi/debug.txt (these are
    copies of the authoritative values in acoutput.h and acpi_drivers.h).

  • 9a9e0d685   ACPI: Remove ACPI_CUSTOM_DSDT_INITRD option ... Browse Code »

    This essentially reverts commit 71fc47a9adf8ee89e5c96a47222915c5485ac437
    ("ACPI: basic initramfs DSDT override support"), because the code simply
    isn't ready.

    It did ugly things to the init sequence to populate the rootfs image
    early, but that just ended up showing other problems with the whole
    approach. The fact is, the VFS layer simply isn't initialized this
    early, and the relevant ACPI code should either run much later, or this
    shouldn't be done at all.

    For 2.6.25, we'll just pick the latter option. We can revisit this
    concept later if necessary.
