Description Marta Löfstedt 2017-11-10 09:52:07 UTC
new test igt@drv_selftest@mock_breadcrumbs was added from CI_DRM_3326. It has dmesg-fail on all shards on all runs so far.

Here are some examples:
https://intel-gfx-ci.01.org/tree/drm-tip/CI_DRM_3329/shard-apl6/igt@drv_selftest@mock_breadcrumbs.html
https://intel-gfx-ci.01.org/tree/drm-tip/CI_DRM_3329/shard-glkb4/igt@drv_selftest@mock_breadcrumbs.html
https://intel-gfx-ci.01.org/tree/drm-tip/CI_DRM_3329/shard-hsw2/igt@drv_selftest@mock_breadcrumbs.html
https://intel-gfx-ci.01.org/tree/drm-tip/CI_DRM_3329/shard-kbl5/igt@drv_selftest@mock_breadcrumbs.html
https://intel-gfx-ci.01.org/tree/drm-tip/CI_DRM_3329/shard-snb6/igt@drv_selftest@mock_breadcrumbs.html

Note that it is not the same issues an all machines, also not that there can be different issues on the same machine on different invocations. So, go mine data from shards.

    drm/i915: Move irqs enabled assertion deeper for mock breadcrumbs
    
    In order to allow the mock breadcrumbs tests to run without device irqs
    being enabled, move the intel_irqs_enabled() assert deeper to just
    before we commit to enabling the HW irq.
    
    v2: Add a FIXME explaining that placing the assertion so deep is not
    ideal, but a compromise for mock breadcrumbs.
