Now with i915_reset_engine() marking the stalled request as guilty, preemption timeout doesn't lead into a GPU hang death spiral; at the loss of potentially resetting a context with no harm (in practice that didn't work out!).
A bit ambivalent on the flip forcing reset, both the stutter and glitch can be seen under load. I'm not sold on the UX; it's bad either way. If we don't break the deadlock, the user can't interact with the system; if we do, they may see a glitch in one app. -Chris _______________________________________________ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/intel-gfx
