A few nits..

1) All other/current logs use "gt%d" (no space).

2) intel_pcode_init also logs a drm_err - do we need two? I suggest
leaving this one only since it has more information.

3) It would have been nicer to have refactoring of intel_pcode_ to work
on uncore separate from adding for_each_gt.

Yeah.

Also the obvious first patch would've been to convert intel_pcode.c
functions from struct drm_i915_private * to intel_uncore *.

Will fix up the first 2 points but about this last point, to not break
incremental compile all callers of the pcode functions also need to be
converted to i915->uncore or gt->uncore (so it's not possible to convert
just intel_pcode.c functions without also converting all callers, if that
was the intent of this comment, unless I am missing something).

Yes the implication is to convert the callers when doing such conversion, we never do broken commits.

But yes the i915_pcode_init() above can be separated out to a separate
patch so I can do that.

AFAIR that will achieve what is suggested, thanks!

Tvrtko
