Hi Jani,
There is still one piece missing in the puzzle to be done.
This is the patch for the HDCP implementation in the kernel needing a
secret key: https://patchwork.freedesktop.org/series/94623/
The implementation currently uses debugfs in testing. The next step is
to use the blob created instea

Sorry, I really haven't had the time to think this through.

Hi Jani, thanks for your review. I got all the user space
implementation ready to see it in context.
