If I'm understanding his series correct it only fixes the mmap issues
not relocs so I don't think it will help all that much. I probably could
send a trybot series letting relocs work on DG1 + his series and that
might work? I guess I'll find out.

GuC submission is enabled by default on ADL-P. We don't have ADL-P in
pre-merge CI currently though :(, just offline runs of about 1800 tests.
Still a awaiting results for that though.

For what it is worth I've run all 1800 locally, via a script, and gotten
solid results back with my IGT updates. There are some failures but I
believe I understand all of them as either test issues or known
differences in behavior between execlists and GuC submission with are
opens (e.g. persistence, semaphores, SUBMIT fence, etc...).
