Yes, but there's a bit a twist: This is definitely end-user documentation,
so maybe should be in admin-guide?

Atm all we have in Documentation/gpu/ is internals for drivers + some
beginnings of uapi documentation for userspace developers.

Jon, what's your recommendation here for subsystem specific
end-user/adming docs?

Thanks, Daniel
