[PATCH 01/12] drm/amd/display: OVT Update on InfoFrame and Mode Management

Solomon Chiu solomon.chiu at amd.com
Fri Feb 18 15:03:18 UTC 2022


From: Chris Park <Chris.Park at amd.com>

[Why]
Integrate OVT timing from DM to DC logic to update info frame
and mode management to report the resolution to the OS.

[How]
Reflect RID and Frame Rate to AVI InfoFrame Version 5.
Define new Timing Standard for OVT timing.
