> Just don't use the guc.
Hello Chris, we are supposed to test with firmware. Any reason for this specific test to NOT use guc?? Thank you.
Comment 7 Chris Wilson 2017-09-18 15:09:56 UTC 
Other than that it is telling us the firmware is broken?

In GLK, with IGT-Version: 1.20-g6d27aca (x86_64) (Linux: 4.15.0-rc4-drm-tip-ww52-commit-05590c3+ x86_64), the tests:

igt@gem_exec_whisper@contexts-forked
igt@gem_exec_whisper@fds-forked
igt@gem_exec_whisper@fds-priority

Are all success, while the test:

igt@gem_exec_whisper@hang-chain-forked 

Do _not_ fail, but it takes around 9 hours to complete. I believe is the same case for the others platforms, but I haven't tested yet. And again, we have another test that takes too much time to finish to add to the list.
