[PATCH 2/3] drm/i915/display: Replace crtc_state's has_drrs by drrs_downclock_mode

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

 



Will be adding some additional control options to DRRS that will
require to have the DRRS downclock mode stored in the crtc_state.

So to optimize memory usage a bit here using it to replace has_drrs
as we can check if the drrs_downclock_mode pointer is different than
null to have the same behavior has has_drrs.
