  • 9a402b649   Input: adbhid - produce all CapsLock key events ... Browse Code »

    The ADB keyboard, which is used for Apple PowerBooks, has strange behavior
    with regard to the capslock key. It keeps track of capslock state
    internally, and it sends a keycode when capslock is engaged and a keycode
    when capslock is disengaged.

    When the current adbhid driver sees that the capslock key is pressed or
    released, it creates both a keypress event and a keyrelease event
    simultaneously. This results in normal capslock behavior.

    While this works, it makes it impossible to remap the capslock key to be a
    control key. However, by translating the 0xff keycode into capslock
    keycodes, we can restore the missing capslock events and make it possible
    to remap the capslock key.

    With this patch, the adbhid driver will translate these 0xff keycodes into
    capslock keypresses and keyreleases if
    /sys/module/adbhid/parameters/restore_capslock_events is set to 1.
    Otherwise it will retain the current behavior. This option is off by
    default because occasionally the 0xff keycode is not a capslock event, and
    a mistake may require the user to tap the capslock key.

  • 555ddbb4e   [POWERPC] adbhid: Enable KEY_FN key reporting ... Browse Code »

    When a Fn key is used in combination with another key in ADB keyboards
    it will generate a Fn event and then a second event that can be a
    different key than pressed (Fn + F1 for instance can generate Fn +
    brightness down if it's configured like that). This enables the
    reporting of the Fn key to the input system.

    As Fn is a dead key for most purposes, it's useful to report it so
    applications can make use of it. One example is apple_mouse
    (https://jake.ruivo.org/uinputd/trunk/apple_mouse/) that emulates the
    second and third keys using a combination of keyboard keys and the mouse
    button. Other applications may use the KEY_FN as a modifier as well.
    I've been updating and using this patch for months without problems.

  • 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.

  • 4b2643d7d   i2c: Fix the i2c_smbus_read_i2c_block_data() prototype ... Browse Code »

    Let the drivers specify how many bytes they want to read with
    i2c_smbus_read_i2c_block_data(). So far, the block count was
    hard-coded to I2C_SMBUS_BLOCK_MAX (32), which did not make much sense.
    Many driver authors complained about this before, and I believe it's
    about time to fix it. Right now, authors have to do technically stupid
    things, such as individual byte reads or full-fledged I2C messaging,
    to work around the problem. We do not want to encourage that.

    I even found that some bus drivers (e.g. i2c-amd8111) already
    implemented I2C block read the "right" way, that is, they didn't
    follow the old, broken standard. The fact that it was never noticed
    before just shows how little i2c_smbus_read_i2c_block_data() was used,
    which isn't that surprising given how broken its prototype was so far.

    There are some obvious compatiblity considerations:
    * This changes the i2c_smbus_read_i2c_block_data() prototype. Users
    outside the kernel tree will notice at compilation time, and will
    have to update their code.
    * User-space has access to i2c_smbus_xfer() directly using i2c-dev, so
    the changed expectations would affect tools such as i2cdump. In order
    to preserve binary compatibility, we give I2C_SMBUS_I2C_BLOCK_DATA
    a new numeric value, and define I2C_SMBUS_I2C_BLOCK_BROKEN with the
    old numeric value. When i2c-dev receives a transaction with the
    old value, it can convert it to the new format on the fly.

  • 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.
