So we emit the instructions whilst i915.semaphores=0 just in case, it is enabled later. This restriction can be lifted with a little more work in handling the missed semaphores, I think, or it may just require a proof that everything is safe as is. -Chris -- Chris Wilson, Intel Open Source Technology Centre _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/intel-gfx
