Subject: [PATCH 03/19] drm/amd/display: reset stream slice count for new ODM policy
Date: Wed, 20 Sep 2023 11:16:08 +0800 [thread overview]
Message-ID: <20230920031624.3129206-4-Wayne.Lin@amd.com> (raw)
In-Reply-To: <20230920031624.3129206-1-Wayne.Lin@amd.com>
From: Wenjing Liu <wenjing.liu@amd.com>
[why]
ODM combine could prevent us from supporting more planes
we will reset ODM slice count back to 1 when all planes have
been removed to maximize the amount of planes supported when
new planes are added.
[how]
reset ODM slice count when all planes are removed.
