NEW packets are send to indicate a discontinuity in the finger coordinate
reporting. Specifically a finger may have moved from slot 0 to 1 or vice versa.
INPUT_MT_TRACK takes care of this for us.
NEW packets have 3 problems:
1) They do not contain middle / right button info (on non clickpads)
The v7 proto differentiates between a primary touch (with high precision)
and a secondary touch (with lower precision). Normally when 2 fingers are
down and one is lifted the still present touch becomes the primary touch,
but some traces have shown that this does not happen always.

Protocol v7 uses the middle / right button bits on clickpads to communicate
location information of a 3th touch (and possible 4th) touch on clickpads.
Specifically when 3 touches are down, if one of the 3 touches is in the

Thank you for your thoughtful reply.
I do not think it is a good idea to add SND_PULSE as it can be easily
implemented by SND_TONE.
It isn't that simple.
Example: if a tone is playing for any reason the clicks do not interrupt
the tone. (It would sound terrible, I've tried it).
