As a very high-level comment, my worry is that you feel like DRM
doesn't supoort this so are inventing it in the DAL. This is
understandable, but the problem is that DRM will come up with a
different interface for things like genlock or FreeSync; one that is
unlikely to match the abstraction in the DAL.

If there are areas you feel core DRM does not address but need to be
supported, please start by working in the core and building out from
there.

Cheers,
Daniel
