Yes. Acquiring the map there is just a bit of paranoia to ensure we having the mapping into the scanout already in place in case of emergencies (and so don't fail along failure paths due to resource conflicts). Hmm, though we only started checking for map failures in 2.20.10 - which would explain why going back to the older ddx masks the issue. And yes, this means we do require a kernel bisect - or some passing inspiron. -Chris -- Chris Wilson, Intel Open Source Technology Centre _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/intel-gfx
