--- Comment #12 from Chris Wilson <chris at chris-wilson.co.uk> ---
The biggest problem is that we only sync between rpm suspend and the rc6
counter at the time of sampling, so there's a gray error where the combined pmu
result may go adrift, and our only limit is that we make sure the reported pmu
value is monotonic.
