Oh hooray, that's just awesome :( So we indeed need to stop the gpu and reset it if there's a non-RS render batch after any RS render batch. Which also means that we need to enable this for _all_ userspace to avoid completely disastrous performance. So uxa, sna, libva, maybe opencl ... I guess before we engage in this endeavor we need to track this down with the hardware people. -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
