[PATCH 0/2] drm/amd: fix VRR race condition during IRQ handling

[tjakobi]

From: Tobias Jakobi <tjakobi@xxxxxxxxxxxxxxxxxxxxx>

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
