Subject: Regression in 5.15 in nouveau
Date: Sat, 4 Dec 2021 17:40:10 +0100	[thread overview]
Message-ID: <da142fb9-07d7-24fe-4533-0247b8d16cdd@sfritsch.de> (raw)

Hi,

when updating from 5.14 to 5.15 on a system with NVIDIA GP108 [GeForce 
GT 1030] (NV138) and Ryzen 9 3900XT using kde/plasma on X (not wayland), 
there is a regression: There is now some annoying black flickering in 
some applications, for example thunderbird, firefox, or mpv. It mostly 
happens when scrolling or when playing video. Only the window of the 
application flickers, not the whole screen. But the flickering is not 
limited to the scrolled area: for example in firefox the url and 
bookmark bars flicker, too, not only the web site. I have bisected the 
issue to this commit:

commit 3e1ad79bf66165bdb2baca3989f9227939241f11 (HEAD)
Author: Christian König <christian.koenig@amd.com>
Date:   Sun Jun 6 11:50:15 2021 +0200

     drm/nouveau: always wait for the exclusive fence

     Drivers also need to to sync to the exclusive fence when
     a shared one is present.

This sounds like performance is impacted severely by that commit. Can 
this be fixed somehow? A partial dmesg is below.

Cheers,
Stefan
