I am not sure I understand the problem. If you have DVFS working (see the link to the wiki) including per-core DVFS (see the earlier comments regarding socket_id), then Linux should automatically adjust the CPU frequency, if you select the right governor (for example "interactive" or "ondemand").
That means that you then simply run your application and Linux will do things automatically. If you want to control DVFS from the application directly, then you need to tell Linux to do so, for example have the application write to the right fields in /sys/devices/system/cpu/cpufreq/* -- Sincerely, Stephan Stephan Diestelhorst Staff Engineer, ARM Research - Systems +44 (0)1223 405662 On Monday 01 June 2015 15:43:26 冰兲轌地 wrote: > thank you very much for your reply! > I want to run a benchmark in the fs mode,but I don't konw how to add DVFS to > each core.
