* The maximum deviation is the sum of the interval over which we
* perform the sampling and the maximum period of any sampled
* clock. That's because the maximum skew between any two sampled
* clock edges is when the sampled clock with the largest period is
* sampled at the end of that period but right at the beginning of the
* sampling interval and some other clock is sampled right at the
* beginning of its sampling period and right at the end of the
* sampling interval. Let's assume the GPU has the longest clock
* period and that the application is sampling GPU and monotonic:
