Subject: [PATCH 0/2] drm/amd: fix VRR race condition during IRQ handling
Date: Mon, 2 Sep 2024 11:40:25 +0200 [thread overview]
Message-ID: <cover.1725269643.git.tjakobi@math.uni-bielefeld.de> (raw)
From: Tobias Jakobi <tjakobi@math.uni-bielefeld.de>
Hello,
this fixes a nasty race condition in the set_drr() callbacks for DCN10
and DCN35 that has existed now since quite some time, see this GitLab
issue for reference.
https://gitlab.freedesktop.org/drm/amd/-/issues/3142
The report just focuses von DCN10, but the same problem also exists in
the DCN35 code.
With best wishes,
Tobias
