frequency-info -------------- analyzing CPU 0: driver: intel_pstate CPUs which run at the same hardware frequency: 0 CPUs which need to have their frequency coordinated by software: 0 maximum transition latency: Cannot determine or is not supported. hardware limits: 1.60 GHz - 3.70 GHz available cpufreq governors: performance powersave current policy: frequency should be within 1.60 GHz and 3.70 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: 3.52 GHz (asserted by call to hardware) boost state support: Supported: yes Active: yes 3400 MHz max turbo 4 active cores 3500 MHz max turbo 3 active cores 3600 MHz max turbo 2 active cores 3700 MHz max turbo 1 active cores idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 0: Number of idle states: 5 Available idle states: POLL C1-SNB C1E-SNB C3-SNB C6-SNB POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 14913 Duration: 5541060 C1-SNB: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 986784 Duration: 164760539 C1E-SNB: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 3135036 Duration: 1202236562 C3-SNB: Flags/Description: MWAIT 0x10 Latency: 80 Usage: 546771 Duration: 256935350 C6-SNB: Flags/Description: MWAIT 0x20 Latency: 104 Usage: 4700518 Duration: 29201847333
