  • f996fc967   PM / Hibernate: Compress hibernation image with LZO ... Browse Code »

    Compress hibernation image with LZO in order to save on I/O and
    therefore time to hibernate/thaw.

    [rjw: Added hibernate=nocompress command line option instead of just
    nocompress which would be confusing, fixed a couple of compiler
    warnings, fixed kerneldoc comments, minor cleanups.]

  • 831441862   Freezer: make kernel threads nonfreezable by default ... Browse Code »

    Currently, the freezer treats all tasks as freezable, except for the kernel
    threads that explicitly set the PF_NOFREEZE flag for themselves. This
    approach is problematic, since it requires every kernel thread to either
    set PF_NOFREEZE explicitly, or call try_to_freeze(), even if it doesn't
    care for the freezing of tasks at all.

    It seems better to only require the kernel threads that want to or need to
    be frozen to use some freezer-related code and to remove any
    freezer-related code from the other (nonfreezable) kernel threads, which is
    done in this patch.

    The patch causes all kernel threads to be nonfreezable by default (ie. to
    have PF_NOFREEZE set by default) and introduces the set_freezable()
    function that should be called by the freezable kernel threads in order to
    unset PF_NOFREEZE. It also makes all of the currently freezable kernel
    threads call set_freezable(), so it shouldn't cause any (intentional)
    change of behaviour to appear. Additionally, it updates documentation to
    describe the freezing of tasks more accurately.

  • 0458d5b4c   USB: add USB-Persist facility ... Browse Code »

    This patch (as886) adds the controversial USB-persist facility,
    allowing USB devices to persist across a power loss during system
    suspend.

    The facility is controlled by a new Kconfig option (with appropriate
    warnings about the potential dangers); when the option is off the
    behavior will remain the same as it is now. But when the option is
    on, people will be able to use suspend-to-disk and keep their USB
    filesystems intact -- something particularly valuable for small
    machines where the root filesystem is on a USB device!

  • 11d77d0c0   power management: remove firmware disk mode ... Browse Code »

    This patch removes the firmware disk suspend mode which is the wrong approach,
    it is supposed to be used for implementing firmware-based disk suspend but
    cannot actually be used for that.

  • b9827e4b2   [PATCH] USB: correct the USB info in Documentation/power/swsusp.txt ... Browse Code »

    The swsusp.txt documentation harshes confusingly on USB, and this patch
    addresses the issue. It's harsh because it blames USB for some issues
    that are generic to all drivers -- especially those supporting removable
    media -- and it's confusing since it says that USB has the issue with
    "suspend" not just swsusp ... while in reality, USB doesn't have the
    issue when real system suspend states are used.

  • 543cc27d0   [PATCH] swsusp: documentation updates ... Browse Code »

    Update suspend-to-RAM documentation with new machines, and makes message
    when processes can't be stopped little clearer. (In one case, waiting
    longer actually did help).

    From: "Rafael J. Wysocki"

    Warn in the documentation that data may be lost if there are some
    filesystems mounted from USB devices before suspend.

    [Thanks to Alan Stern for providing the answer to the question in the
    Q:-A: part.]

  • ca0aec0f7   [PATCH] swsusp: make image size limit tunable ... Browse Code »

    Make the suspend image size limit tunable via /sys/power/image_size.

    It is necessary for systems on which there is a limited amount of swap
    available for suspend. It can also be useful for optimizing performance of
    swsusp on systems with 1 GB of RAM or more.

  • 3e1d1d28d   [PATCH] Cleanup patch for process freezing ... Browse Code »

    1. Establish a simple API for process freezing defined in linux/include/sched.h:

    frozen(process) Check for frozen process
    freezing(process) Check if a process is being frozen
    freeze(process) Tell a process to freeze (go to refrigerator)
    thaw_process(process) Restart process
    frozen_process(process) Process is frozen now

    2. Remove all references to PF_FREEZE and PF_FROZEN from all
    kernel sources except sched.h

    3. Fix numerous locations where try_to_freeze is manually done by a driver

    4. Remove the argument that is no longer necessary from two function calls.

    5. Some whitespace cleanup

    6. Clear potential race in refrigerator (provides an open window of PF_FREEZE
    cleared before setting PF_FROZEN, recalc_sigpending does not check
    PF_FROZEN).

    This patch does not address the problem of freeze_processes() violating the rule
    that a task may only modify its own flags by setting PF_FREEZE. This is not clean
    in an SMP environment. freeze(process) is therefore not SMP safe!

    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!
