[PATCH v2 libinput 6/6] tablet: add touch arbitration
Peter Hutterer

Tue Sep 6 01:04:55 UTC 2016
So far we've relied on the wacom kernel module to do touch arbitration for us
but that won't be the case in upcoming kernels. Implement touch arbitration in
userspace by pairing the two devices and suspending the touch device whenever
a tool comes into proximity.
In the future more sophisticated arbitration can be done (e.g. only touches
which are close to the pen) but let's burn that bridge when we have to cross
it.
Note that touch arbitration is "device suspend light", i.e. we leave the
device enabled and the fd is active. Tablet interactions are comparatively
short-lived, so closing the fd and asking logind for a new one every time the
pen changes proximity is suboptimal. Instead, we just keep a boolean around
and discard all events while it is set.

Changes to v1:
- drop the previous evdev_device_suspend() approach and use a ignore_events
boolean in the dispatch instead.
- add test for suspending/resuming the touch device during arbitration
- use a common helper for each arbitration test. the tests only differ in
the second device created and what events we expect so let's re-use
everything else

+ at section tablet-touch-arbitration Tablet touch arbitration
+
+"Touch arbitration" is the terminology used when touch events are suppressed
+while the pen is in proximity. Since it is almost impossible to use a stylus
+or other tool without triggering touches with the hand holding the tool,
+touch arbitration serves to reduce the number of accidental inputs.
+The wacom kernel driver currently provides touch arbitration but for other
+devices arbitration has to be done in userspace.
+
+libinput uses the @ref libinput_device_group to decide on touch arbitration
+and automatically discards touch events whenever a tool is in proximity.
+The exact behavior is device-dependent.
