Hijacking the thread a bit, not to be considered a blocker for this
series:

Is there a plan to kzalloc i915->gt[0] too in intel_gt_probe_all() so we
wouldn't need to have intel_gt gt0 in struct drm_i915_private? And the
to_gt() inline would return i915->gt[0] instead of &i915->gt0? (And
maybe i915_drv.h wouldn't need the definition of intel_gt anymore! :o)

BR,
Jani.
