The work will already be scheduled (everytime we add the first element, the work is scheduled, and the scheduled bit is cleared before the work is executed). So we aren't saving the kworker from having to process another work, but we may make that having nothing to do. The question is whether we want to trap the kworker here, and presumably you will also want to add a cond_resched() between passes. -Chris -- Chris Wilson, Intel Open Source Technology Centre _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
