Waitboost is a legacy feature implemented in the Host Turbo algorithm. This

Afaiu user doesn't have to call gem_wait, the boost will happen whenever a
request waits to be submitted to GuC because of an unmet depedency. This
has to be done from i915 because GuC has not yet seen the request.
Rest of the cover letter is fine.
Ok, thanks,
