Adding more locked operations to execbuf is scary though, with some workloads perf highlights the cost of the atomic for an uncontested mutex as being where the majority of the time is going. At this point I am questing perf, but it is the last remaining locked instruction in that path... -Chris -- Chris Wilson, Intel Open Source Technology Centre _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/intel-gfx
