[GIT PATCH] ACPI patches for 2.6.23-rc1

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi Linus,

please pull from: 

git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux-acpi-2.6.git release

Fixes regressions -- a build failure, an oops, some dmesg spam.
Also fixes some D-state issues and adds ACPI module auto-loading.
Yes, I'd hoped to get the last two in before rc1.
I'm hopeful that a couple-days into rc2 is sufficiently early for them.

This will update the files shown below.

thanks!

-Len

    ACPI: Kconfig: remove CONFIG_ACPI_SLEEP from source
    
    As it was a synonym for (CONFIG_ACPI && CONFIG_X86),
    the ifdefs for it were more clutter than they were worth.
    
    For ia64, just add a few stubs in anticipation of future
    S3 or S4 support.

    ACPI: Kconfig: always enable CONFIG_ACPI_SLEEP on X86
    
    The SMP dependency on HOTPLUG_CPU and SUSPEND_SMP
    caused more harm than good -- making ACPI sleep
    support vanish for configs missing those options.
    So simply select them on the (ACPI && SMP && X86) systems
    that need them.
    
    Also, remove the prompt for ACPI_SLEEP,
    virtually nobody (intentionally) enables ACPI without it.

    ACPI: Kconfig: fold /proc/acpi/sleep under CONFIG_ACPI_PROCFS
    
    /proc/acpi/sleep has had its own "default n" option,
    ACPI_SLEEP_PROC_SLEEP, for many months.
    Time to delete ACPI_SLEEP_PROC_SLEEP.
    
    Users that still need /proc/acpi/sleep can still get it
    along with the other deprecated /proc/acpi files
    by enabling CONFIG_ACPI_PROCFS.
    
    Also delete ACPI_SLEEP_PROC_FS, which was an umbrella
    for /proc/acpi/sleep, wakeup, alarm, because it was
    effectively just a synonym for ACPI_SLEEP.

    ACPI: autoload modules - Create ACPI alias interface
    
    Modify modpost (file2alias.c) to add acpi*:XYZ0001: alias in modules.alias

    alias acpi*:SNY5001:* sony_laptop
    alias acpi*:SNY6001:* sony_laptop
    for e.g. the sony_laptop module.
    This module matches against all ACPI devices with a HID or CID of SNY5001
    or SNY6001
    
    Export an uevent and modalias sysfs file containing the string:
    [MODALIAS=]acpi:PNP0C0C:
    additional CIDs are concatenated at the end.

    Fallout from f8a7c6fe14f556ca8eeddce258cb21392d0c3a2f.  However, looking
    at it shows that checks done in ASUS_LED_UNREGISTER() can't trigger
    at all (we never get to asus_led_exit() if registration fails) and
    if that registration fails, we actually leak stuff.  IOW, it's worse
    than just replacing class_dev with dev in there - the tests themselves
    had been papering over the lousy cleanup logics.

    ACPI: Implement the set_target() callback from pm_ops
    
    In the future some drivers may need to use ACPI to determine the low power
    states in which to place their devices, but to provide the drivers with this
    information the ACPI core needs to know what sleep state the system is going to
    enter.  Namely, the device's state should not be too high power for given system
    sleep state and, if the device is supposed to be able to wake up the system, its
    state should not be too low power for the wake up to be possible).  For this
    purpose, the ACPI core needs to implement the set_target() method in 'struct
    pm_ops' and store the target system sleep state passed by the PM core in a
    variable.
