[PATCH v2 11/19] drm/i915/dsb: Don't use DSB to load the LUTs during full modeset

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

 



From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>

Using the DSB for LUT loading during full modesets would require
some actual though. Let's just use mmio for the time being.
