Thanks - I appreciate the feedback :-) As I said earlier, I think the maximum frequency can act as a level of energy efficiency request. If a workload knows that a certain level of performance is adequate, the maximum frequency request can prevent e.g. ondemand unnecessarily raising the frequency. --Antti
