2015-02-01Input: MT - add support for balanced slot assignmentHenrik Rydberg6-16/+25
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.

The current code tries to consider all states and transitions to properly detect which finger is attached to which slot. The code is quite huge and difficult to read. If the sensor manages to group the touch points but is not reliable in giving tracking ids, we can simply use the kernel tracking method. Note that it is already used by Cr-48 Chromebooks. Incidentaly, this fixes a bug reported by Peter Hutterer: """ on the Lenovo T440, run: evemu-record /dev/input/event4 | grep BTN_ then put one, two, three, two fingers down when you go from 3 to 2 fingers the driver sends a spurious BTN_TOUCH 0 event: E: 0.000000 0001 014a 0001 # EV_KEY / BTN_TOUCH 1 E: 0.000000 0001 0145 0001 # EV_KEY / BTN_TOOL_FINGER 1 E: 0.770008 0001 0145 0000 # EV_KEY / BTN_TOOL_FINGER 0 E: 0.770008 0001 014d 0001 # EV_KEY / BTN_TOOL_DOUBLETAP 1 E: 1.924716 0001 014d 0000 # EV_KEY / BTN_TOOL_DOUBLETAP 0 E: 1.924716 0001 014e 0001 # EV_KEY / BTN_TOOL_TRIPLETAP 1 .. changing from 3 to 2 fingers now E: 3.152641 0001 014a 0000 # EV_KEY / BTN_TOUCH 0 E: 3.152641 0001 014d 0001 # EV_KEY / BTN_TOOL_DOUBLETAP 1 E: 3.152641 0001 014e 0000 # EV_KEY / BTN_TOOL_TRIPLETAP 0 E: 3.176948 0001 014a 0001 # EV_KEY / BTN_TOUCH 1 quick look in the kernel shows it's caused by hw.z going to 0 for a packet, so probably a firmware bug. either way, it makes it hard to track BTN_TOUCH as signal that at least one finger is down.

Especially, we don't know how to identify the device yet apart from the PNP ID.
