I see that CI got stuck somewhere, but the failure doesn't seem to be related to this patch. Otherwise it all looks good, with the improved git comment as Ashutosh asked and the comment above: Reviewed-by: Andi Shyti <andi.shyti@linux.intel.com> Andi > > u32 intel_rps_get_cagf(struct intel_rps *rps, u32 rpstat) > > { > > struct drm_i915_private *i915 = rps_to_i915(rps); > > u32 cagf; > > > > - if (IS_VALLEYVIEW(i915) || IS_CHERRYVIEW(i915)) > > + if (GRAPHICS_VER(i915) >= 12) > > + cagf = (rpstat & GEN12_CAGF_MASK) >> GEN12_CAGF_SHIFT; > > + else if (IS_VALLEYVIEW(i915) || IS_CHERRYVIEW(i915)) > > cagf = (rpstat >> 8) & 0xff; > > else if (GRAPHICS_VER(i915) >= 9) > > cagf = (rpstat & GEN9_CAGF_MASK) >> GEN9_CAGF_SHIFT; > > @@ -2099,7 +2127,7 @@ static u32 read_cagf(struct intel_rps *rps) > > freq = vlv_punit_read(i915, PUNIT_REG_GPU_FREQ_STS); > > vlv_punit_put(i915); > > } else if (GRAPHICS_VER(i915) >= 6) { > > - freq = intel_uncore_read(uncore, GEN6_RPSTAT1); > > + freq = intel_rps_read_rpstat(rps); > > } else { > > freq = intel_uncore_read(uncore, MEMSTAT_ILK); > > } > > diff --git a/drivers/gpu/drm/i915/gt/intel_rps.h b/drivers/gpu/drm/i915/gt/intel_rps.h > > index 4509dfdc52e0..76c8404d8416 100644 > > --- a/drivers/gpu/drm/i915/gt/intel_rps.h > > +++ b/drivers/gpu/drm/i915/gt/intel_rps.h > > @@ -47,6 +47,8 @@ u32 intel_rps_get_rp1_frequency(struct intel_rps *rps); > > u32 intel_rps_get_rpn_frequency(struct intel_rps *rps); > > u32 intel_rps_read_punit_req(struct intel_rps *rps); > > u32 intel_rps_read_punit_req_frequency(struct intel_rps *rps); > > +u32 intel_rps_read_rpstat(struct intel_rps *rps); > > +u32 intel_rps_read_rpstat_fw(struct intel_rps *rps); > > void gen6_rps_get_freq_caps(struct intel_rps *rps, struct intel_rps_freq_caps *caps); > > void intel_rps_raise_unslice(struct intel_rps *rps); > > void intel_rps_lower_unslice(struct intel_rps *rps); > > diff --git a/drivers/gpu/drm/i915/i915_pmu.c b/drivers/gpu/drm/i915/i915_pmu.c > > index 958b37123bf1..67140a87182f 100644 > > --- a/drivers/gpu/drm/i915/i915_pmu.c > > +++ b/drivers/gpu/drm/i915/i915_pmu.c > > @@ -371,7 +371,6 @@ static void > > frequency_sample(struct intel_gt *gt, unsigned int period_ns) > > { > > struct drm_i915_private *i915 = gt->i915; > > - struct intel_uncore *uncore = gt->uncore; > > struct i915_pmu *pmu = &i915->pmu; > > struct intel_rps *rps = >->rps; > > > > @@ -394,7 +393,7 @@ frequency_sample(struct intel_gt *gt, unsigned int period_ns) > > * case we assume the system is running at the intended > > * frequency.
