Could have kept use of intel_lr_context_descriptor for better separation.
I was leaning the other way, since the code doesn't want
intel_lr_context_descriptor() just happens to want to reuse some of the
bits e.g. engine->ctx_desc_template | lrca
Thats true, but it was at least using an exported function with
documented content, rather than directly fishing out stuff from
essentially private data elsewhere.
i.e. lrc->context_desc != ce->lrc_desc and I would prefer it to be
clarified as to exactly what the GuC expects.
Yes that would be best. Cc-ed Dave for when he is back to comment what
does GuC really wants in there.
