Probably you can go through Documentation/cpu-freq/* for this information. Governor decides which frequency you will switch to and when. Policy decides which frequencies you *can* switch to. > Are there a different cpufreq policy structure created for each cpu? A separate policy exists for each group of CPU sharing clock line. So, it may happen that there is a policy per CPU if they don't share clock line at all.. > Will policy structure change when governor changes or when will it change? Policy structure doesn't change with governor. It will get updated only when you try to play with min/max frequency a CPU can switch to OR hotplug/unplug a CPU.. _______________________________________________ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev
