Thanks for catching this, because GEN12_RPSTAT1 is indeed available for all
Gen12+. It was done this way because the voltage bits of GEN12_RPSTAT1 are
only available for DG1/DG2. Anyway in v9 I have changed this to just:
/* Available for all Gen12+/dGfx */
hwmon->rg.gt_perf_status = GEN12_RPSTAT1;
That is because hwmon is only availbable for dGfx (there's a check in Patch
1). Also, because of this change the 'IS_DG1(i915) || IS_DG2(i915)' check
has been moved to hwm_in_is_visible.
Thanks.
