Subject: [PATCH 0/3] HID: multitouch: fix a corner case of some Win 8 devices
Date: Thu, 15 Jun 2017 15:32:02 +0200 [thread overview]
Message-ID: <20170615133205.15441-1-benjamin.tissoires@redhat.com> (raw)
It looks like the Microsft certification misses one case of released fingers.
The (only) solution we can have against that is to wait for a hundred of ms,
and if no input report comes in, consider that the touches should have been
released. The spec, as I read it, enforces that.
Arek, can you please give a test to this new series?
I managed to find out a way to have the IRQ and the timeout exclusive, and
also added a few optimizations.
Cheers,
Benjamin
