Comment 1 Chris Wilson 2018-11-09 10:46:19 UTC
21:22 ickle : <3> [385.741372] Switching between 241 contexts timed out 21:22 ickle : ... 21:22 ickle : <7> [385.848580] i915_gem_set_wedged \x09Execlist CSB read 2, write 5 [mmio:5], tasklet queued? yes (enabled) 21:22 ickle : ksoftirqd strikes again 21:23 ickle : no, that maybe a little simplistic 21:23 ickle : it executed 1a06 and 1a07 whilst dumping the state 21:24 ickle : so maybe it just accumulated a lot of slowness
Comment 2 Francesco Balestrieri 2018-11-12 09:29:55 UTC
Do we need more occurrences of this to investigate? So far there has been one.
Comment 3 Chris Wilson 2018-11-12 10:53:51 UTC
This one has the hallmark of being an uncommon sw issue. I'm still betting on ksoftirqd being at the heart of it, proof left to the imagination.
Comment 4 Francesco Balestrieri 2018-11-14 15:12:46 UTC
Still no other occurrences. I'm going setting it to high priority.
Comment 5 Chris Wilson 2018-11-29 12:48:31 UTC
https://intel-gfx-ci.01.org/tree/drm-tip/Patchwork_10950/fi-cfl-8109u/igt@i915_selftest@live_contexts.html Same again, running very slowly but progress is still being made. Still taking over 2s for a 100 context switches is bogus.
Comment 6 Francesco Balestrieri 2019-01-09 07:53:14 UTC
Occurred several times in a day, then never again for almost two months. Closing.
