Subject: [PATCH 13/43] drm/amd/display: Fix noise issue on HDMI AV mute
Date: Tue, 12 Mar 2024 17:20:06 +0800 [thread overview]
Message-ID: <20240312092036.3283319-14-Wayne.Lin@amd.com> (raw)
In-Reply-To: <20240312092036.3283319-1-Wayne.Lin@amd.com>
From: Leo Ma <hanghong.ma@amd.com>
[Why]
When mode switching is triggered there is momentary noise visible on
some HDMI TV or displays.
[How]
Wait for 2 frames to make sure we have enough time to send out AV mute
and sink receives a full frame.
