Sure, I've run 3 jobs: * v5.11-rc6 as a reference, to see the original issue: https://lava.collabora.co.uk/scheduler/job/3187848 * + your debug patch: https://lava.collabora.co.uk/scheduler/job/3187849 * + the "breaking" commit reverted, passing the tests: https://lava.collabora.co.uk/scheduler/job/3187851 You can see the history of the test branch I'm using here, with the 3 revisions mentioned above: https://gitlab.collabora.com/gtucker/linux/-/commits/linux-5.11-rc6-nyan-big-drm-read/ Hope that helps, Guillaume _______________________________________________ iommu mailing list iommu@lists.linux-foundation.org https://lists.linuxfoundation.org/mailman/listinfo/iommu
