I'm also a bit unsure about the DDI one, since if we ever have a port enabled with a bogus pipe link, we probably still want to shut down the port. At least that part is pretty important to not end up with a black screen in a lot of cases, atm Egbert Eich is debugging such a case for sdvo ... -Daniel -- Daniel Vetter Software Engineer, Intel Corporation +41 (0) 79 365 57 48 - http://blog.ffwll.ch ___ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/intel-gfx
