| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Fimware 8.1 has a bug in which the extra buttons are only sent when the ExtBit is 1.

| * | Input: synaptics - fix middle button on Lenovo 2015 productsDmitry Torokhov2015-03-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On the X1 Carbon 3rd gen (with a 2015 broadwell cpu), the physical middle button of the trackstick (attached to the touchpad serio device, of course) seems to get lost. Actually, the touchpads reports 3 extra buttons, which falls in the switch below to the '2' case. Let's handle the case of odd numbers also, so that the middle button finds its way back.

| * | Input: synaptics - skip quirks when post-2013 dimensionsBenjamin Tissoires2015-03-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

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).

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().

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.

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.
