Subject: [PATCH AUTOSEL 5.10 02/11] drm/amd/display: For stereo keep "FLIP_ANY_FRAME"
Date: Wed, 24 Aug 2022 21:38:23 -0400 [thread overview]
Message-ID: <20220825013836.23205-2-sashal@kernel.org> (raw)
In-Reply-To: <20220825013836.23205-1-sashal@kernel.org>
From: Alvin Lee <alvin.lee2@amd.com>
[ Upstream commit 84ef99c728079dfd21d6bc70b4c3e4af20602b3c ]
[Description]
Observed in stereomode that programming FLIP_LEFT_EYE
can cause hangs. Keep FLIP_ANY_FRAME in stereo mode so
the surface flip can take place before left or right eye
