No. We don't claim a fence unless used (the or none clause above). If the object is untiled, like ringbuffers, we don't assign a fence. The problem I'm thinking about for the future is having an iomap cached for fenced and unfenced access, i.e. we need to track the type of iomap similarly to regular vmaps. -Chris _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
