Hi Vincent, Why do we have two interfaces arch_scale_freq_power() and arch_scale_cpu_power()? Does it make sense to consolidate them now ? Regards Preeti U Murthy On 05/23/2014 09:22 PM, Vincent Guittot wrote:

Use the new arch_scale_cpu_power in order to reflect the original capacity of a CPU instead of arch_scale_freq_power which is more linked to a scaling of the capacity linked to the frequency.
