Hi John, I was just wondering what's happening with this patch series? Are you still working on it? Does it need any testing? It is still in progress. Although currently stalled because it was decided to first replace the driver's seqno usage with request structures wherever possible. The theory being that this is safer and more sensible that having the scheduler cause out-of-order seqnos and the various work-arounds to cope with that. ___ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/intel-gfx
