This is what I have:
https://git.linuxtv.org/hverkuil/media_tree.git/log/?h=hdcp
This is very old and somewhat messy.
It uses ioctls for the bksv's, but I wonder if array/compound controls
wouldn't be more appropriate (those didn't exist when this was written
originally).
It also needs to be checked against HDCP 2 so it can support that as well
(or at least be easily extended for that).
Regards,
Hans
