I feel it would be good to have a config to control HDCP2.2 instead of having such a strong binding with MEI. If MEI have some issues we don’t want I915 to go down even if HDCP is not even required or used for a particular distribution or a design. @Daniel/Sean - What do you suggest ? > >Userspace interface remains unchanged as version agnostic.
