| | | | | | | | | | | | | | | | | | | | | | | This feature synchronizes multiple displays with various timings to a display with the highest refresh rate it is enabled if edid caps flag multi_display_sync is set to one There are limitations on refresh rates allowed that can be synchronized. That would prevent from underflow and other potential corruptions. Multi display synchronization is using the same functions as timing_sync in order to minimize redunduncy and decision to disable synchronization is based on trigger parametre set in DM Feature is developed for DCN1 and DCE11 Signed-off-by: Mikita Lipski <mikita.lipski@amd.com> Reviewed-by: Mikita Lipski <Mikita.Lipski@amd.com> Acked-by: Harry Wentland <harry.wentland@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
