[PATCH 07/22] drm/amd/display: Do not enable replay when vtotal update is pending.

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Danny Wang <danny.wang@xxxxxxx>

[Why&How]
Vtotal is not applied to HW when handling vsync interrupt.
Make sure vtotal is aligned before enable replay.
