2015-03-08Input: synaptics - skip quirks when post-2013 dimensionsBenjamin Tissoires1-1/+1
Post-2013 Lenovo laptops provide correct min/max dimensions, which are different with the ones currently quirked. According to https://bugzilla.kernel.org/show_bug.cgi?id=91541 the following board ids are assigned in the post-2013 touchpads: t440p/t440s: LEN0036 -> 2964/2962 t540p: LEN0034 -> 2964 Using 2961 as the common minimum makes these 3 laptops OK. We may need to update those values later if other pnp_ids has a lower board_id.

2015-03-08Input: synaptics - support min/max board id in min_max_pnpid_tableDaniel Martin1-12/+30
Add a min/max range for board ids to the min/max coordinates quirk. This makes it possible to restrict quirks to specific models based upon their board id. The define ANY_BOARD_ID (0) serves as a wild card.

The firmware of the X240 (LEN0035, 2013/12) exposes the same values x [1232..5710], y [1156..4696] as the quirk applies. Cc: [email protected] Signed-off-by: Daniel Martin <[email protected]> Acked-by: Hans de Goede <[email protected]> Signed-off-by: Dmitry Torokhov <[email protected]>
2015-03-08Input: synaptics - query min dimensions for fw v8.1Daniel Martin1-2/+8
Query the min dimensions even if the check SYN_EXT_CAP_REQUESTS(priv->capabilities) >= 7 fails, but we know that the firmware version 8.1 is safe. With that we don't need quirks for post-2013 models anymore as they expose correct min and max dimensions.

2015-03-07Input: psmouse - disable "palm detection" in the focaltech driverMathias Gottschlag1-10/+0
Apparently, the threshold for large contact area seems to be rather low on some devices, causing the touchpad to frequently freeze during normal usage. Because we do now know how we are supposed to use the value in question, this commit just drops the related code completely.

2015-02-15Input: ALPS - do not mix trackstick and external PS/2 mouse dataPali Rohár2-53/+151
Previously dev2 device was used for both external PS/2 mouse and internal trackstick device (if available). This change introduces dev3 device which is used for external PS/2 mouse data and dev2 is now used only for trackstick. In case that trackstick is not present dev2 is not created, so userspace does not see non existent device in system. Because laptops with ALPS devices often do not use i8042 active multiplexing all data (from touchpad, trackstick and external PS/2 mouse) come to one port. So it is not possible to know if external PS/2 mouse is connected or not. In most cases external PS/2 mouse is not connected so driver will create dev3 input device after first bare PS/2 packet will be received. So there will not be "ghost" input device. This change also helps in identifying possible problems in future if driver decides to report 6-bytes trackstick packets as 3-bytes bare PS/2 (data will be reported to dev3 instead dev2).

2015-02-15Input: ALPS - fix trackstick detection on some Dell LatitudesDmitry Torokhov1-22/+56
On some Dell Latitudes we fail to identify presence of trackstick unless we reset the device. The issue is quite benign as we do perform reset in alps_init(), so the trackstick ends up working, but mouse name reported to userspace is not accurate. In order to fix the issue while avoiding the additional lengthy reset we move the resrt to alps_detect() and keep the discovered state to be used later in alps_init().

2015-02-03Input: synaptics - use dmax in input_mt_assign_slotsBenjamin Tissoires1-1/+4
When tapping a clickpad with two fingers, there is a chance that the sensor sees first only one finger, and at the next scan only the second one. In this case, the sensors says that there has been only one finger on the clickpad, which moved really fast between two scans. We can try to counter this by adding a limit to what an actual finger can move between 2 scans. A distance of 1cm between two scans for one finger seems reasonable. However, this is not really accurate because the resolution in X and in Y differs. But heh, that's how the in-kernel tracking works right now, and its job is quite good, even with this approximation. This parameter solves most of the jumps observed, not all of them however. But this is a hardware defect, and we might not be able to get something better without much heavier computations.

2015-02-01Input: MT - add support for balanced slot assignmentHenrik Rydberg4-4/+4
Some devices are not fast enough to differentiate between a fast-moving contact and a new contact. This problem cannot be fully resolved because information is truly missing, but it is possible to safe-guard against obvious mistakes by restricting movement with a maximum displacement. The new problem formulation for dmax > 0 cannot benefit from the speedup for positive definite matrices, but since the convergence is faster, the result is about the same. For a handful of contacts, the latency difference is truly negligible.
