  • 958a65f20   [POWERPC] Add missing of_node_put in drivers/macintosh/therm_adt746x.c ... Browse Code »

    of_node_put is needed before discarding a value received from
    of_find_node_by_name, eg in error handling code.

    The semantic patch that makes the change is as follows:

  • 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.

  • 7eebde700   [POWERPC] Souped-up of_platform_device support ... Browse Code »

    This patch first splits of_device.c and of_platform.c, the later containing
    the bits relative to of_platform_device's. On the "breaks" side of things,
    drivers uisng of_platform_device(s) need to include asm/of_platform.h now
    and of_(un)register_driver is now of_(un)register_platform_driver.

    In addition to a few utility functions to locate of_platform_device(s),
    the main new addition is of_platform_bus_probe() which allows the platform
    code to trigger an automatic creation of of_platform_devices for a whole
    tree of devices.

    The function acts based on the type of the various "parent" devices encountered
    from a provided root, using either a default known list of bus types that can be
    "probed" or a passed-in list. It will only register devices on busses matching
    that list, which mean that typically, it will not register PCI devices, as
    expected (since they will be picked up by the PCI layer).

    This will be used by Cell platforms using 4xx-type IOs in the Axon bridge
    and can be used by any embedded-type device as well.

    return value. Also, treat the return value as const, so we can
    constify get_property later.

    Now that i2c_add_driver() doesn't need the module owner to be set by
    hand, we can delete it from the drivers. This patch catches all of the
    drivers that I found in the current tree (if a driver sets the .owner by
    hand, it's not a problem, just not needed.)

    Just about every i2c chip driver sets the I2C_DF_NOTIFY flag, so we
    can simply make it the default and drop the flag. If any driver really
    doesn't want to be notified when i2c adapters are added, that driver
    can simply omit to set .attach_adapter. This approach is also more
    robust as it prevents accidental NULL pointer dereferences.

  • 0365ba7fb   [PATCH] ppc64: SMU driver update & i2c support ... Browse Code »

    The SMU is the "system controller" chip used by Apple recent G5 machines
    including the iMac G5. It drives things like fans, i2c busses, real time
    clock, etc...

    The current kernel contains a very crude driver that doesn't do much more
    than reading the real time clock synchronously. This is a completely
    rewritten driver that provides interrupt based command queuing, a userland
    interface, and an i2c/smbus driver for accessing the devices hanging off
    the SMU i2c busses like temperature sensors. This driver is a basic block
    for upcoming work on thermal control for those machines, among others.

  • 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!
