To be more precise, the reason here is that we are not wedging the GPU but the expectation is that a wait upon a request that hangs reports the hang. Since the wait on GPU activity is explicit in the ioctl, the presumption is that the user actually cares about that activity and so should be given greater information about how it completes (timeout, GPU hung, or success). -Chris -- Chris Wilson, Intel Open Source Technology Centre _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/intel-gfx
