Of course (I hope!). But they're internal to NVIDIA and they have no real
interest in sharing. Sometimes things can be found out from occasoinal code
drops, e.g. the more recent gk20a android driver. (Of course that HW has no
display component, so no use for something like this.)

Seeing what the blob does + manual poking based on observed patterns.
