  • 5523662ed   Input: add userio module ... Browse Code »

    Debugging input devices, specifically laptop touchpads, can be tricky
    without having the physical device handy. Here we try to remedy that
    with userio. This module allows an application to connect to a character
    device provided by the kernel, and emulate any serio device. In
    combination with userspace programs that can record PS/2 devices and
    replay them through the /dev/userio device, this allows developers to
    debug driver issues on the PS/2 level with devices simply by requesting
    a recording from the user experiencing the issue without having to have
    the physical hardware in front of them.

  • 3a341a4c3   Input: rotary-encoder - add support for quarter-period mode ... Browse Code »

    Some encoders have both outputs low in stable states, others also have
    a stable state with both outputs high (half-period mode) and some have
    a stable state in all steps (quarter-period mode). The driver used to
    support the former states and with this change it can also support the
    later.

    This commit also deprecates the 'half-period' property and introduces
    a new property 'steps-per-period'. This property specifies the
    number of steps (stable states) produced by the rotary encoder
    for each GPIO period.

  • 073e570d7   Input: alps - only Dell laptops have separate button bits for v2 dualpoint sticks ... Browse Code »

    It turns out that only Dell laptops have the separate button bits for
    v2 dualpoint sticks and that commit 92bac83dd79e ("Input: alps - non
    interleaved V2 dualpoint has separate stick button bits") causes
    regressions on Toshiba laptops.

    This commit adds a check for Dell laptops to the code for handling these
    extra button bits, fixing this regression.

    This patch has been tested on a Dell Latitude D620 to make sure that it
    does not reintroduce the original problem.

  • a736775db   Input: add MT_TOOL_PALM ... Browse Code »

    Currently there are only two "tools" that can be specified by a multi-touch
    driver: MT_TOOL_FINGER and MT_TOOL_PEN. In working with Elan (The touch
    vendor) and discussing their next-gen devices it seems that it will be
    useful to have more tools so that their devices can give the upper layers
    of the stack hints as to what is touching the sensor.

    In particular they have new experimental firmware that can better
    differentiate between palms vs fingertips and would like to plumb a patch
    so that we can use their hints in higher-level gesture soft- ware. The
    firmware on the device can reasonably do a better job of palm detection
    because it has access to all of the raw sensor readings as opposed to just
    the width/pressure/etc that are exposed by the driver. As such, the
    firmware can characterize what a palm looks like in much finer-grained
    detail and this change would allow such a device to share its findings with
    the kernel.

  • 5469b1965   Input: xpad - update docs to reflect current state ... Browse Code »

    The last time this documentation was accurate was
    just over 8 years ago. In this time we've added
    support for two new generations of Xbox console
    controllers and dozens of third-party controllers.

    This patch unifies terminology and makes it explicit
    which model of controller a sentence refers to.

    It also expands certain sections to address the latest
    versions of Xbox controllers.

    Thus this documentation should now be useful to
    end users and not contain out-right untruths.

    This is the patch's second revision. Prior versions
    of this patch altered the driver's TODO list. That
    change has been pulled out of this documentation
    update patch.

  • 36189cc3c   Input: elantech - fix touchpad initialization on Gigabyte U2442 ... Browse Code »

    The hw_version 3 Elantech touchpad on the Gigabyte U2442 does not accept
    0x0b as initialization value for r10, this stand-alone version of the
    driver: http://planet76.com/drivers/elantech/psmouse-elantech-v6.tar.bz2

    Uses 0x03 which does work, so this means not setting bit 3 of r10 which
    sets: "Enable Real H/W Resolution In Absolute mode"

    Which will result in half the x and y resolution we get with that bit set,
    so simply not setting it everywhere is not a solution. We've been unable to
    find a way to identify touchpads where setting the bit will fail, so this
    patch uses a dmi based blacklist for this.

    It wasn't really clear from the gamepad-API description how ABS values are
    mapped exactly. Clarify that negative is left/up and positive is
    right/down. Unfortunately, this means I screwed up the Wii U ProController
    ABI. Anyhow, this just means we continue to have 0 compatible gamepad
    drivers in the kernel. User-space needs to fix them up, anyway, as all
    other gamepads are also incompatible.

  • 6e0fe2e57   input: document gamepad API and add extra keycodes ... Browse Code »

    Until today all gamepad input drivers report their data differently. It is
    nearly impossible to write applications for more than one device in a
    generic way. Therefore, this patch introduces a uniform gamepad API which
    will be used for all new drivers.

    Instead of mapping buttons by their labels, we now map them by position.
    This allows applications to work with any gamepad regardless of the labels
    on the buttons. Furthermore, we standardize the ABS_* codes for analog
    triggers and sticks.

    For D-Pads the long overdue BTN_DPAD_* codes are introduced. They should
    be fairly obvious how to use. To avoid confusion, the action buttons now
    have BTN_EAST/SOUTH/WEST/NORTH aliases.

    This is effectively already in force through input_mt_init_slots, and uinput

    Since slots are a kernel-genenerated axis only, non-zero minimums make

    minimum as kernel bug if it ever happens.
