Subject: [PATCH 08/14] drm/amd/display: Fix eDP will flash when boot to OS
Date: Fri, 12 Nov 2021 08:54:32 +0800 [thread overview]
Message-ID: <20211112005438.5505-9-Wayne.Lin@amd.com> (raw)
In-Reply-To: <20211112005438.5505-1-Wayne.Lin@amd.com>
From: Brandon Syu <Brandon.Syu@amd.com>
[WHY]
With eDP DSC enabled and set 4K 60Hz, there would be screen
corruption when booting to OS or enabling the driver.
[HOW]
Avoid powering down VDD when we cannot apply eDP fast boot.
