igt/tests/kms_pipe_crc_basic --run-subtest nonblocking-crc-pipe-A Also happens on HSW and BDW, and in other tests as well. I think it would happen on ILK and IVB as well if we enabled runtime PM on those platforms. Regression from the two-stage wm programming. Is there any special system setup or non-default driver settings required to trigger this? I don't see this warning when I run the suggested test on SNB, and CI doesn't seem to be reporting it either as far as I can see.

Maybe run the pm_rpm tests first so that they drop the autosuspend delay to 0 etc., and then see if it happens.

Still no luck reproducing this on my end. Is this something you can reproduce 100% of the time or is it a sporadic issue? BAT reporting same warning on igt/tests/pm_rpm --run-subtest basic-rte Also seen in pm_rpm@basic-pci-d3-state on snb-x220t in [1], which is somewhat odd as that test always fails (as in is unable to autosuspend the device) on particular machine for some reason. [1] /archive/results/CI_IGT_test/Patchwork_1518/ Happens also with kms_pipe_crc_basic@nonblocking-crc-pipe-b-frame-sequence Proposed fix: https://patchwork.freedesktop.org/patch/75903/ Can QA verify whether this solves the problem *** Bug 94645 has been marked as a duplicate of this bug. *** Patch is pushed now to -nightly, closing this. *** Bug 94384 has been marked as a duplicate of this bug. *** |
