Subject: [PATCH 0/4] reduce Surface Pro 3 multitouch jitter
Date: Sat, 30 Jun 2018 14:19:49 -1000 [thread overview]
Message-ID: <cover.1530402641.git.joeypabalinas@gmail.com> (raw)
The Surface Pro 3 firmware doesn't reliably send contact lift off
reports nor handle invalid report values gracefully.
To reduce touchscreen input jitter:
- add MT_QUIRK_NOT_SEEN_MEANS_UP to the MT_CLS_WIN_8
- drop invalid report values
Joey Pabalinas (4):
HID: multitouch: add MT_QUIRK_NOT_SEEN_MEANS_UP to MT_CLS_WIN_8 quirks
HID: multitouch: don't check HID_GROUP_MULTITOUCH_WIN_8 for serial protocol
HID: multitouch: drop reports containing invalid values
HID: multitouch: remove unneeded else conditional cases

Patches have been tested on my personal Surface Pro 3 for a
couple months without any problems, as well as being run in my
Arch Linux AUR kernel package [1] without a single complaint
so far.
