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: 1.20 GHz - 3.90 GHz available cpufreq governors: performance powersave current policy: frequency should be within 1.20 GHz and 3.90 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 1.39 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes 3900 MHz max turbo 4 active cores 3900 MHz max turbo 3 active cores 3900 MHz max turbo 2 active cores 3900 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 C1E C3 C6 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 498574 Duration: 910535 C1: Flags/Description: MWAIT 0x00 Latency: 1 Usage: 163495 Duration: 18422261 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 18550 Duration: 4332173 C3: Flags/Description: MWAIT 0x10 Latency: 59 Usage: 24322 Duration: 7025629 C6: Flags/Description: MWAIT 0x20 Latency: 82 Usage: 189872 Duration: 845394686
