iptsd in chromeos #3
Description
Hi Hayataka,
I have finally found a fix for older devices (Intel Gen < skylake) to boot brunch with kernel 5.4 and in preparation to switch brunch to kernel 5.4 I am trying to implement the new ipts method with iptsd in chromeos.
I currently have both ipts kernel part and iptsd built correctly (as far as I can tell) and I can see input which looks correct in "evtest" but touches are not recognized in chromeos.
I was wondering if you used a specific iptsd patch in your chromeos iptsd implementation ?
Between, I have been reading the progress on the camera support and you and the other participants are really doing great ! Thanks for that :)

Hi sebanc,
I also noticed that iptsd won't work as-is. I have this patch
This patch is written for the older iptsd written in Go, before switching to C. But the basics are the same I guess.
It's not complete yet, but at least it enables finger touch input other than taps in chrome browser (you can now scroll, pinch-to-zoom, long-tap, ...). Looks like it's fully working on ARC at a glance, including taps.
I haven't opened an issue on iptsd repo and even haven't told this issue to StollD yet, because I've been obsessed with cameras and the other things these days :D
So, I'd appreciate it a lot if you can discuss this issue with StollD.
A prebuilt binary is also available here
Thanks :)

I made the patch by comparing the
evtestoutput on v4.19-ipts and this iptsd and saw whatEvent codeare missing.If I remember correctly, the iptsd still lacks some
Event code, but I gave up adding it before as it seems to be difficult for me :Dsebanc commentedon Nov 15, 2020
Thanks for the detailed explanation and the patch :)
This patch is still very mysterious for me as I only looked at old ipts code but never really investigated the hid events.
I will raise an issue on iptsd and hopefully StollD will be able to help.
Thanks a lot for all this info and best of luck with your other projects !
