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?
