I'd like to amend this with the following (on this patch instead of the other, so that ppl actually can find it with git blame): "Furthermore actually setting bit12 results in gpu hangs both on snb and ivb. Ben Widawsky discovered a ppt that claims that both bit12 and bit11 must be set, but that doesn't help either. And last but not least, MI_FLUSH seems to work regardless of the setting of these bits." Eric, Ben, is that ok? -Daniel -- Daniel Vetter Mail: dan...@ffwll.ch Mobile: +41 (0)79 365 57 48 _______________________________________________ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/intel-gfx
