  • 296699de6   Introduce CONFIG_SUSPEND for suspend-to-Ram and standby ... Browse Code »

    Introduce CONFIG_SUSPEND representing the ability to enter system sleep
    states, such as the ACPI S3 state, and allow the user to choose SUSPEND
    and HIBERNATION independently of each other.

    Make HOTPLUG_CPU be selected automatically if SUSPEND or HIBERNATION has
    been chosen and the kernel is intended for SMP systems.

    Also, introduce CONFIG_PM_SLEEP which is automatically selected if
    CONFIG_SUSPEND or CONFIG_HIBERNATION is set and use it to select the
    code needed for both suspend and hibernation.

    The top-level power management headers and the ACPI code related to
    suspend and hibernation are modified to use the new definitions (the
    changes in drivers/acpi/sleep/main.c are, mostly, moving code to reduce
    the number of ifdefs).

    There are many other files in which CONFIG_PM can be replaced with
    CONFIG_PM_SLEEP or even with CONFIG_SUSPEND, but they can be updated in
    the future.

    Replace CONFIG_SOFTWARE_SUSPEND with CONFIG_HIBERNATION to avoid
    confusion (among other things, with CONFIG_SUSPEND introduced in the
    next patch).

  • e3920fb42   [PATCH] Disable CPU hotplug during suspend ... Browse Code »

    The current suspend code has to be run on one CPU, so we use the CPU
    hotplug to take the non-boot CPUs offline on SMP machines. However, we
    should also make sure that these CPUs will not be enabled by someone else
    after we have disabled them.

    The functions disable_nonboot_cpus() and enable_nonboot_cpus() are moved to
    kernel/cpu.c, because they now refer to some stuff in there that should
    better be static. Also it's better if disable_nonboot_cpus() returns an
    error instead of panicking if something goes wrong, and
    enable_nonboot_cpus() has no reason to panic(), because the CPUs may have
    been enabled by the userland before it tries to take them online.

  • 6e1819d61   [PATCH] swsusp: userland interface ... Browse Code »

    This patch introduces a user space interface for swsusp.

    The interface is based on a special character device, called the snapshot
    device, that allows user space processes to perform suspend and resume-related
    operations with the help of some ioctls and the read()/write() functions.
     Additionally it allows these processes to allocate free swap pages from a
    selected swap partition, called the resume partition, so that they know which
    sectors of the resume partition are available to them.

    The interface uses the same low-level system memory snapshot-handling
    functions that are used by the built-it swap-writing/reading code of swsusp.

    The interface documentation is included in the patch.

    The patch assumes that the major and minor numbers of the snapshot device will
    be 10 (ie. misc device) and 231, the registration of which has already been
    requested.

  • 25761b6eb   [PATCH] swsusp: move snapshot functionality to separate file ... Browse Code »

    The following patch moves the functionality of swsusp related to creating and
    handling the snapshot of memory to a separate file, snapshot.c

    This should enable us to untangle the code in the future and eventually to
    implement some parts of swsusp.c in the user space.

    The patch does not change the code.

    Using CPU hotplug to support suspend/resume SMP. Both S3 and S4 use
    disable/enable_nonboot_cpus API. The S4 part is based on Pavel's original S4
    SMP patch.

    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!
