Martin,

How to get the current status of this issue on cfl? if I check at https://intel-gfx-ci.01.org/tree/drm-tip/combined-issues-by-run.html cfl is used for fast feedback where content protection tests are not executed.

And shards-iclb has no connector with hdcp capability. I am not sure how did we get these observations. Could you please help on this?

Sorry for the delay. What you want to look at is the CI-wide idle runs: https://intel-gfx-ci.01.org/tree/drm-tip/drmtip.html (link can be found in https://intel-gfx-ci.01.org).

In the future, I would like people to use CI Bug Log to find all the failures associated to a bug, but that will require a bit more development (a non-intel-hosted instance).

CFL HDCP1.4 key load issue is locally verified to be fixed by https://patchwork.freedesktop.org/patch/265985/

The series https://patchwork.freedesktop.org/series/53493/ is awaiting the merger

ICL needs to be debugged yet.

Thanks! CFL is not seeing the "Could not load HDCP keys" error anymore, but it still fails:

Martin difficult to fix this, as this is not reproducible on the CFL/KBL I have tested locally. When I can use the fi-cfl-8109u or problematic KBL fi system, for debugging, we can fix this.

Mostly errors are KSV list not available on DP port which mean LSPCon related issues.
