I realize I missed checkpatch on patch-7 before send-mail. Will fix that on next rev.
Patch #2 also has checkpatch failures which I was aware of - I'm still wresting with how to instance those register tables in a clean readable way using.

Subject: [RFC 7/7] drm/i915/guc: Print the GuC error capture output register list.
Print the GuC captured error state register list (offsets and values) when gpu_coredump_state printout is invoked.
Also, since the GuC can report multiple engine class registers in a single notification event, parse the captured data (appearing as a stream of structures) to identify multiple captures of different 'engine-capture-group-outputs'.
Finally, for each 'engine-capture-group-output', identify the last running context and print already-identified vma's so that user's output report follows the same layout as execlist submission. I.e.
engine1-registers, engine1-context-vmas, engine2-registers, engine2-context-vmas, etc.
