  • 7eff2e7a8   Driver core: change add_uevent_var to use a struct ... Browse Code »

    This changes the uevent buffer functions to use a struct instead of a
    long list of parameters. It does no longer require the caller to do the
    proper buffer termination and size accounting, which is currently wrong
    in some places. It fixes a known bug where parts of the uevent
    environment are overwritten because of wrong index calculations.

    Many thanks to Mathieu Desnoyers for finding bugs and improving the
    error handling.

    configures it.

    module autoloading by userspace.

  • 1855256c4   drivers/firmware: const-ify DMI API and internals ... Browse Code »

    Three main sets of changes:

    1) dmi_get_system_info() return value should have been marked const,
    since callers should not be changing that data.

    2) const-ify DMI internals, since DMI firmware tables should,
    whenever possible, be marked const to ensure we never ever write to
    that data area.

    3) const-ify DMI API, to enable marking tables const where possible
    in low-level drivers.

    And if we're really lucky, this might enable some additional
    optimizations on the part of the compiler.

    The bulk of the changes are #2 and #3, which are interrelated. #1 could
    have been a separate patch, but it was so small compared to the others,
    it was easier to roll it into this changeset.

  • 7b6dff982   Input: usbtouchscreen - correctly set 'phys' ... Browse Code »

    This patch fixes a nasty typo in usbtouchscreen driver. The typo
    is inherited from the original mtouchusb. It used to make the input
    subsytem to incorrectly report the physical device ids to userspace
    that in turn is very confusing for, e.g. XInput hotplug facilities
    in setups with multiple identical touchscreens.

  • 5a6eb676d   Input: appletouch - improve powersaving for Geyser3 devices ... Browse Code »

    The appletouch geyser3 devices found in the Intel Macs (and possibly
    some later PPC ones?) send a constant stream of packets after the first
    touch. This results in the kernel waking up around once every couple of
    milliseconds to process them, making it almost impossible to spend any
    significant amount of time in C3 state on a dynamic HZ kernel. Sending
    the mode initialization code makes the device shut up until it's touched
    again. This patch does so after receiving 10 packets with no interesting
    content.

  • 080c652d6   Input: i8042 - give more trust to PNP data on i386 ... Browse Code »

    On some boxes that don't have PS/2 mice connected at startup BIOS
    completely disables AUX port and attempts to access it result in
    hosed keyboard. Historically we do not trust ACPI/PNP data on
    i386 and try to poke AUX port even if we did not find an active
    PNP node for it. However in cases when BIOS writers got KBD port
    properly described we can assume that they did the right thing
    for AUX port as well.

  • 1d25891f3   Input: ads7846 - re-check pendown status before reporting events ... Browse Code »

    Pendown status from the PENIRQ pin is currently read only at the beginning
    of a sample set. If the pen is lifted just after sampling has began then
    sampled values become wrong.

    This patch adds an optional platform penirq_recheck_delay attribute. If
    non-zero, samples are only reported to the input subsystem if PENIRQ is
    still active that long after the samples taken.

  • e4f488619   Input: ads7846 - introduce sample settling delay ... Browse Code »

    The ads7846 driver has support for filtering, but when the chip gets
    deselected between samples this causes noise. This patch adds support
    for an optional settling delay time, so that two consecutive samples
    will be taken with the specified delay time apart. This ensures that
    the chip won't be deselected, so the noise won't appear.

    Filtering can still be done, but will have less work to do since each
    time a new sample is taken the same delay applies.

  • 4994cd8da   Input: xpad - add support for leds on xbox 360 pad ... Browse Code »

    Export LEDs on Xbox360 pad via led subsystem as a single device in
    /sys/class/leds/xpad[0-9]+.

    Xbox360 pad has four leds, which form a circle. Unfortunately the leds
    can't be controlled independently and can only display a predefined
    set of patterns (for example one is turned on wile others are off or
    a rotating pattern - 1-2-3-4). To activate a pattern one needs to send
    a specific command to the device (see http://www.free60.org/wiki/Gamepad).

    Led subsystem allows us to set brightness, but there is nothing like
    brightness on this device. So brightness is actually interpreted as
    the command (only values between 0 and 14 are accepted).

  • 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.

  • 7b595756e   sysfs: kill unnecessary attribute->owner ... Browse Code »

    sysfs is now completely out of driver/module lifetime game. After
    deletion, a sysfs node doesn't access anything outside sysfs proper,
    so there's no reason to hold onto the attribute owners. Note that
    often the wrong modules were accounted for as owners leading to
    accessing removed modules.

    This patch kills now unnecessary attribute->owner. Note that with
    this change, userland holding a sysfs node does not prevent the
    backing module from being unloaded.

    For more info regarding lifetime rule cleanup, please read the
    following message.
