Increase the severity as this bug largely impacted IGT pass rate, and we blacklist 175 kms_flip cases and 41 pm_rpm cases. Created attachment 114483 [details] [review] avoid spurious PM interrupts Could you try the attached patch? (In reply to Imre Deak from comment #6) > Created attachment 114483 [details] [review] [review] > avoid spurious PM interrupts > > Could you try the attached patch? Test this patch, run ./pm_rpm --run-subtest cursor 10 cycles and ./kms_flip --run-subtest vblank-vs-modeset-rpm-interruptible 10 cycles. This error goes away. The fix is merged to -nightly. Test on the latest -nightly kernel and igt, I don't see this error. Verified.Fixed. Closing old verified. |
