This seems like a slight change in user observable > behaviour. You would not be able to observe the difference after wakeup in state between a sync_file and busy_ioctl/wait_ioctl, as a query after wakeup will see the same signaled bit. So the only possible difference is a change in wakeup order; but process wakeup/execution order is definitely not defined by us :) -Chris _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
