I think this flag is still WIP. It was added very recently so I'm assuming there is some plan for it (not that I like adding half baked dead stuff like this). So we may want to wait a bit to see where it's going. The reason I deleted this specific statement is that we zero the crtc state before .compute_config() so this one would remain dead code even if the flag starts to get used for something. > > I think the proper replacement is the mode flag stuff below, this is just > interim stuff that fell through the review. > > With that prep patch to get rid of these 2 hunks above: > > Reviewed-by: Daniel Vetter <daniel.vetter@xxxxxxxx> > > Also surplus Acked-by: Daniel Vetter <daniel.vetter@xxxxxxxx> on the patch > to delete I915_MODE_FLAG_DSI_PERIODIC_CMD_MODE in case I miss the new > version. > -- Ville Syrjälä Intel _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
