From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx> As we did with plane updates we can split the color management updates to noarm+arm pair. The CSC matrix coefficients can all be written in the noarm hook, with just the PIPE_CSC_mode (the arming register) left behind in the arm hook. Also make the scaler/pfit completely lockless as that too adds overhead into the vblank evasion critical section.
