I think the fix correctly addresses gpu hangs related to the host-mem-barrier test. My initial report wrongly attributed gpu hangs to host-mem-barrier. Subsequent testing showed that hangs were caused by other tests. I provided feedback with partial information because of the time consuming nature of root-causing gpu hangs. Curro felt confident in this fix, so I took the time to verify which tests triggered the hangs. _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
