--- Comment #14 from Ramalingam C <ramalingam.c at intel.com> ---
Martin,

We need to file different bugs for the content protection failures based on the
cause for it. 
This is needed because few failures are due to the HDCP sink, which can't be
fixed.

The cause has to be picked from the kernel demsg debug logs as given below. 

1. [drm:intel_hdcp_read_valid_bksv.isra.0 [i915]] Bksv is invalid
      Ex:
https://intel-gfx-ci.01.org/tree/drm-tip/Trybot_3967/fi-icl-u3/igt@kms_content_protection@legacy.html

2. [drm:intel_hdcp_auth [i915]] KSV list failed to become ready (-110)
      Ex:
https://intel-gfx-ci.01.org/tree/drm-tip/CI_DRM_5750/shard-kbl5/igt@kms_content_protection@atomic.html


Could you please help with this?

This bug can be used to track the content protection enable failure due to the
HDCP key load issue. But I believe this is no more seen on the latest HDCP
results.
