Description Ramalingam C 2018-11-02 17:16:06 UTC 
With dmesg-fail HDCP key loadability is failed.

Comment 1 Ramalingam C 2018-11-02 17:18:50 UTC 
With the debugging, it is found that power well status for SKL_DISP_PW_1 needs a special treatment on gen 9.

We are working on verifying the fix.
Comment 2 Ramalingam C 2018-11-03 05:02:13 UTC 
https://patchwork.freedesktop.org/patch/260059/ fixes the issue as per the CI results(https://patchwork.freedesktop.org/series/51968/).

Comment 4 Ramalingam C 2018-11-26 05:46:27 UTC 
@ https://intel-gfx-ci.01.org/tree/drm-tip/combined-issues-by-run.html content protection tests are failing due to the Lspcon's failure to authenticate as a repeater. Key loadability issue is fixed with imre's patch for powerwell status check. So I am closing this as fixed.
Comment 5 Francesco Balestrieri 2018-12-28 09:00:53 UTC 
Not reproduced in CI, closing.
