Actually since the Panel fitter is at the Pipe level and also the PIPESRC register, this has been exposed through crtc property. But with crtc also, it is kind of associated with primary planes only.

Follow-up from my side ... could we just expose this through primary planes, or is the damn panel fitter at the wrong spot in the pipeline? -Daniel -- Daniel Vetter Software Engineer, Intel Corporation +41 (0) 79 365 57 48 - http://blog.ffwll.ch _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/intel-gfx
