> GuC owns the execlists state and the context IDs used for submission, so
> the status of the ports and the CSB entries are not something we control
> or can decode from the i915 side, therefore we can avoid dumping it. A

> GuC dumps all the required events in the GuC logs when verbosity is set
> high enough.

Would not be worth including, or is it not very helpful for debugging
curious engine stalls?
