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 Tobias Jakobi (2): drm/amd/display: Avoid race between dcn10_set_drr() and dc_state_destruct() drm/amd/display: Avoid race between dcn35_set_drr() and dc_state_destruct() .../amd/display/dc/hwss/dcn10/dcn10_hwseq.c | 20 +++++++++++-------- .../amd/display/dc/hwss/dcn35/dcn35_hwseq.c | 20 +++++++++++-------- 2 files changed, 24 insertions(+), 16 deletions(-) -- 2.44.2
