Subject: [PATCH v2 00/12] HID: fix for generic input processing
Date: Thu,  3 Feb 2022 15:32:14 +0100	[thread overview]
Message-ID: <20220203143226.4023622-1-benjamin.tissoires@redhat.com> (raw)

Hi,

this is the v2 of my series which reworks the HID report processing.

I took Ping's comments into account, and amended my MR with the
regression tests[0].
More specifically, the tests (and thus this new version of the series)
enforces that only one BTN_TOOL_* event gets forwarded between each
EV_SYN frame, and that BTN_TOUCH are properly translated too.

This also magivally solved some worrying transitions we had in the
pen state machine where the pen was jumping from "eraser" to "in
contact". This new behavior enforces a "out-of-range" state in the
middle, making it easier for userspace to understand now.

Again, tests are welcome :)

Cheers,
Benjamin
