  • 9eebed7de   Input: elantech - fix for newer hardware versions (v7) ... Browse Code »

    * Fix version recognition in elantech_set_properties

    The new hardware reports itself as v7 but the packets'
    structure is unaltered.

    * Fix packet type recognition in elantech_packet_check_v4

    The bitmask used for v6 is too wide, only the last three bits of
    the third byte in a packet (packet[3] & 0x03) are actually used to
    distinguish between packet types.
    Starting from v7, additional information (to be interpreted) is
    stored in the remaining bits (packets[3] & 0x1c).
    In addition, the value stored in (packet[0] & 0x0c) is no longer
    a constant but contains additional information yet to be deciphered.
    This change should be backwards compatible with v6 hardware.

    The June 2013 Macbook Air (13'') has a new trackpad protocol; four new
    values are inserted in the header, and the mode switch is no longer
    needed. This patch adds support for the new devices.

  • eeb065582   Input: synaptics - fix sync lost after resume on some laptops ... Browse Code »

    In summary, the symptom is intermittent key events lost after resume
    on some machines with synaptics touchpad (seems this is synaptics _only_),
    and key events loss is due to serio port reconnect after psmouse sync lost.
    Removing psmouse and inserting it back during the suspend/resume process
    is able to work around the issue, so the difference between psmouse_connect()
    and psmouse_reconnect() is the key to the root cause of this problem.

    After comparing the two different paths, synaptics driver has its own
    implementation of synaptics_reconnect(), and the missing psmouse_probe()
    seems significant, the patch below added psmouse_probe() to the reconnect
    process, and has been verified many times that the issue could not be reliably
    reproduced.

    There are two PS/2 commands in psmouse_probe():

    1. PSMOUSE_CMD_GETID
    2. PSMOUSE_CMD_RESET_DIS

    Only the PSMOUSE_CMD_GETID seems to be significant. The
    PSMOUSE_CMD_RESET_DIS is irrelevant to this issue after trying
    several times. So we have only implemented this patch to issue
    the PSMOUSE_CMD_GETID so far.

  • 0c6a61657   Input: trackpoint - Optimize trackpoint init to use power-on reset ... Browse Code »

    The trackpoint driver sets various parameter default values, all of
    which happen to be power-on defaults (Source: IBM TrackPoint Engineering
    Specification, Version 4.0. Also confirmed by empirical data).

    By sending the power-on reset command to reset all parameters to
    power-on state, we can skip the lengthy process of programming all
    parameters. In testing, ~2.5 secs of time writing parameters was reduced
    to .35 seconds waiting for power-on reset to complete.

  • 75af9e56c   Input: ALPS - add "Dolphin V1" touchpad support ... Browse Code »

    These touchpads use a different protocol; they have been seen on Dell
    N5110, Dell 17R SE, and others.

    The official ALPS driver identifies them by looking for an exact match
    on the E7 report: 73 03 50. Dolphin V1 returns an EC report of
    73 01 xx (02 and 0d have been seen); Dolphin V2 returns an EC report of
    73 02 xx (02 has been seen).

    Dolphin V2 probably needs a different initialization sequence and/or
    report parser, so it is left for a future commit.

    To properly setup event parameters for emulated events, pass
    the appropriate flag to the slot initialization function. Also,
    all MT-related events should be setup before initialization.

    Incidentally, this solves the issue of doubly filtered pointer
    events.

  • 48064bdcd   Input: synaptics - fix 1->3 contact transition reporting ... Browse Code »

    Investigating the following gesture highlighted two slight implementation
    errors with choosing which slots to report in which slot when multiple
    contacts are present:

    Action SGM AGM (MTB slot:Contact)
    1. Touch contact 0 (0:0)
    2. Touch contact 1 (0:0, 1:1)
    3. Lift contact 0 (1:1)
    4. Touch contacts 2,3 (0:2, 1:3)

    In step 4, slot 1 was not being cleared first, which means the same
    tracking ID was being used for reporting both the old contact 1 and the
    new contact 3. This could result in "drumroll", where the old contact 1
    would appear to suddenly jump to new finger 3 position.

    Similarly, if contacts 2 & 3 are not detected at the same sample, step 4
    is split into two:

    Action SGM AGM (MTB slot:contact)
    1. Touch contact 0 (0:0)
    2. Touch contact 1 (0:0, 1:1)
    3. Lift contact 0 (1:1)
    4. Touch contact 2 (0:2, 1:1)
    5. Touch contact 3 (0:2, 1:3)

    In this case, there was also a bug. In step 4, when contact 1 moves from
    SGM to AGM and contact 2 is first reported in SGM, slot 0 was actually
    empty. So slot 0 can be used to report the new SGM (contact 0),
    immediately. Since it was empty, contact 2 in slot 0 will get a new
    tracking ID.
