Looks good then, pushed, thanks for the patch.
The ring is kept as busy, but the queue depth is drastically reduced (from N_buffers to 32). Since both numbers are arbitrary, I am not adverse to the change, but I would feel happier if it was demonstrated that the new test is still capable of detecting bugs deliberately introduced into the ring synchronisation code. -Chris -- Chris Wilson, Intel Open Source Technology Centre _______________________________________________ Intel-gfx mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/intel-gfx
