Well, that hunk switches from checking dev_priv->pch_pf_size (which is now in crtc->config, so we'd need to check the right pipe/cpu_transcoder first) to the register value, which is just plain bogus. While at it we could fix the XXX in haswell_crtc_disable, which is now possible with the pch pfit tracking. -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
