Subject: [GIT PATCH] ACPI patches for 2.6.21-rc4
Date: Thu, 22 Mar 2007 02:13:24 -0400	[thread overview]
Message-ID: <> (raw)

Hi Linus,

please pull from: 

git:// release

This batch includes fixes to two visible 2.6.21 regressions -- the immediate suspend wakeup,
and the the acpi_serialize deadlock.  The later is a revert that touches a lot of code,
but should be okay even in -rc4 as it returns the code to how it was in 2.6.20.

This will update the files shown below.



ps. individual patches are available on
and a consolidated plain patch is available here:

    ACPI: IA64: fix %ll build warnings
    acpi_integer is 64-bits on all platforms, and so was defined as a u64.
    i386 and x86_64 define u64 as unsigned long long.
    ia64 defines u64 as long.
    While these are all 64-bits, the kernel build warns about formating
    a "long" with %ll:
    drivers/ata/libata-acpi.c:176: warning: long long unsigned int format, acpi_integer arg (arg 5)
    So skip using "u64" and define acpi_integer as "unsigned long long"
    to make gcc happy with %ll.

    ACPI: IA64: fix allnoconfig build
    The evils of Kconfig's select bite us once again...
    ia64/Kconfig selects ACPI, which depends on PM.
    But select ignores dependencies, allnoconfig
    chooses CONFIG_PM=n, and thus the menu of sub-options
    under ACPI vanish, which breaks the build.
    Manually select PM along with ACPI for now.
    Some day, we should delete them both, or fix select.

    ACPI: Only use IPI on known broken machines (AMD, Dothan/BaniasPentium M)
    Use IPI for blacklisted CPUs, add parameter IPI vs LAPIC
    Currently, Linux disables lapic timer for all machines with C2 and higher
    C-state support.
    According to Intel only specific Intel models (Banias/Dothan) are broken
    in respect of not waking up from C2 with lapic.
    However, I am not sure about the naming of the parameter and how it
    could/should get integrated into the dyntick part
    (CONFIG_GENERIC_CLOCKEVENTS). There, a more fine grained check (TSC
    still running?, ..) is needed? Does this make sense (always use
    CLOCK_EVT_NOTIFY_BROADCAST_ON, but use OFF if forced by use_ipi=0:
    clockevents_notify(use_ipi ? CLOCK_EVT_NOTIFY_BROADCAST_ON :

    ACPI: ibm-acpi: allow module to load when acpi notifiers can't be set (v2)
    This patch allows for ibm-acpi to coexist (with diminished functionality) with
    other drivers like ACPI_BAY.  ibm-acpi will simply disable the functions it is
    not able to register ACPI notifiers for.

    ACPI: resolve HP nx6125 S3 immediate wakeup regression
    Moving disable GPEs from enter_sleep up into sleep_prepare fixed
    the disabled SCI on S4 on Acer laptops.
    However, it caused an immediate S3 resume on the HP nx6125.
    Apparently, on the HP, a GPE was getting re-enabled after
    the prepare, but before the enter.
    Close that window by restoring the GPE disable on enter.
    This is redundant in most cases, but closes this window,
    where S3 and S4 paths differ.

    ACPI: Add support to parse 2nd MADT
    When a BIOS bug presents multiple APIC/MADTs,
    Linux currently uses the 1st and ignores the 2nd.
    But some machines work better if we use the 2nd.
    Add a warning and boot parameter "acpi_apic_instance=2"
    to allow parsing the 2nd.
    No change to default behaviour in this patch.
