And it doesn't appear to be bound to any specific test.

We were able to filter those out by looking at whether the ELSP remained active, but in commit beecec901790 ("drm/i915/execlists: Preemption!") that became problematic as we now anticipate receiving a context-switch event for preemption while ELSP may be empty. To restore the spurious interrupt suppression, add a counter for the expected number of pending context-switches and skip if we do not need to handle this interrupt to make forward progress. Chris patch was integrated into CI_DRM_3277 I want a couple of more clean runs before I close this and archive the cibuglog. No occurances on +10 runs I am closing |
