Chris Wilson c43dd6b414 drm/i915/selftests: Check power consumption at min/max frequencies ... A basic premise of RPS is that at lower frequencies, not only do we run slower, but we save power compared to higher frequencies. For example, when idle, we set the minimum frequency just in case there is some residual current. Since the power curve should be a physical relationship, if we find no power saving it's likely that we've broken our frequency handling, so test!
