Description Ville Syrjala 2016-01-19 20:36:02 UTC

IGT-Version: 1.13-g51e965f (x86_64) (Linux: 4.4.0-gfxbench+ x86_64)
Test requirement not met in function test_read_crc, file kms_pipe_crc_basic.c:227:
Test requirement: valid_connectors
No connector found for pipe 1
Subtest nonblocking-crc-pipe-B: SKIP (0.000s)

All the other very similar tests passed just fine. Looking at the results file we see it ran drv_module_reload just prior to this test, so perhaps we have some problem where we fail to probe the modes during driver load?

And naturally I forgot the link to the results: /archive/results/CI_IGT_test/Patchwork_1224/

Comment 2 Daniel Vetter 2016-01-19 21:04:06 UTC

Maybe related to bug #93769?
