[Intel-gfx] [RFC PATCH 0/1] GuC engine reset support

[Fernando Pacheco]

Another attempt at providing GuC a list of registers to
save/restore during engine resets [1].

The list we provide GuC should mirror, with possibly some exceptions,
the list of registers applied during execlists_resume/enable_execlists.
Any ideas on how to flag any discrepancies (yet flexible enough to
handle exceptions) between the two lists e.g. via a selftest? I would
like something stronger than a comment that just states the other needs
updating. Or should I take this to mean a different approach is needed?

Thanks,
Fernando
