Description Tomi Sarvela 2018-07-10 07:39:10 UTC

Continuing with the series of "Initial findings" with Intel-GFX-CI and i915 selftests.

SKL with IOMMU enabled fail the following tests with:
i915: probe of 0000:00:02.0 failed with error -25

This is supposedly a great success and expected behaviour, so the bug is just a placeholder for CI filters.

Not really IGT either since piglit isn't a part of IGT...

Comment 2 Chris Wilson 2018-07-28 15:59:42 UTC

The probe fail message isn't currently being flagged as an issue (and it shouldn't be), lets hope it continues.

Comment 3 Lakshmi 2018-08-22 13:39:48 UTC

This is not a bug and works as expected.

But, igt@drv_selftest@live_guc test is failing that needs fix from guc
Dmesg:

For this issue there is a separate bug filed.

Closing this as works as expected.
