Subject: [PATCH AUTOSEL 5.15 35/41] drm/amd/display: Correct MPC split policy for DCN301
Date: Thu, 3 Feb 2022 15:32:39 -0500 [thread overview]
Message-ID: <20220203203245.3007-35-sashal@kernel.org> (raw)
In-Reply-To: <20220203203245.3007-1-sashal@kernel.org>
From: Zhan Liu <zhan.liu@amd.com>
[ Upstream commit ac46d93235074a6c5d280d35771c23fd8620e7d9 ]
[Why]
DCN301 has seamless boot enabled. With MPC split enabled
at the same time, system will hang.
[How]
Revert MPC split policy back to "MPC_SPLIT_AVOID". Since we have
ODM combine enabled on DCN301, pipe split is not necessary here.
