Use smoothed version of sensor array data to calculate movement and add weight to prior values when calculating average. This gives more granular and more predictable movement.

2014-03-28Input: synaptics - add manual min/max quirkBenjamin Tissoires
The new Lenovo Haswell series (-40's) contains a new Synaptics touchpad. However, these new Synaptics devices report bad axis ranges. Under Windows, it is not a problem because the Windows driver uses RMI4 over SMBus to talk to the device. Under Linux, we are using the PS/2 fallback interface and it occurs the reported ranges are wrong. Of course, it would be too easy to have only one range for the whole series, each touchpad seems to be calibrated in a different way. We can not use SMBus to get the actual range because I suspect the firmware will switch into the SMBus mode and stop talking through PS/2 (this is the case for hybrid HID over I2C / PS/2 Synaptics touchpads). So as a temporary solution (until RMI4 land into upstream), start a new list of quirks with the min/max manually set.

2014-03-26Input: cypress_ps2 - don't report as a button padsHans de Goede
The cypress PS/2 trackpad models supported by the cypress_ps2 driver emulate BTN_RIGHT events in firmware based on the finger position, as part of this no motion events are sent when the finger is in the button area. The INPUT_PROP_BUTTONPAD property is there to indicate to userspace that BTN_RIGHT events should be emulated in userspace, which is not necessary in this case. When INPUT_PROP_BUTTONPAD is advertised userspace will wait for a motion event before propagating the button event higher up the stack, as it needs current abs x + y data for its BTN_RIGHT emulation. Since in the cypress_ps2 pads don't report motion events in the button area, this means that clicks in the button area end up being ignored, so INPUT_PROP_BUTTONPAD actually causes problems for these touchpads, and removing it fixes: https://bugs.freedesktop.org/show_bug.cgi?id=76341 Reported-by: Adam Williamson <awilliam@redhat.com> Tested-by: Adam Williamson <awilliam@redhat.com> Reviewed-by: Peter Hutterer <peter.hutterer@who-t.net> Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

2013-12-18Input: elantech - improve clickpad detectionHans de Goede
The current assumption in the elantech driver that hw version 3 touchpads are never clickpads and hw version 4 touchpads are always clickpads is wrong. There are several bug reports for this, ie: https://bugzilla.redhat.com/show_bug.cgi?id=1030802 http://superuser.com/questions/619582/right-elantech-touchpad-button-not-working-in-linux I've spend a couple of hours wading through various bugzillas, launchpads and forum posts to create a list of fw-versions and capabilities for different laptop models to find a good method to differentiate between clickpads and versions with separate hardware buttons. Which shows that a device being a clickpad is reliable indicated by bit 12 being set in the fw_version. I've included the gathered list inside the driver, so that we've this info at hand if we need to revisit this later.

* 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.

2013-06-04Input: synaptics - fix sync lost after resume on some laptopsEric Miao
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.
