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 - 3.10 GHz available cpufreq governors: performance powersave current policy: frequency should be within 1.20 GHz and 3.10 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: 2.25 GHz (asserted by call to hardware) boost state support: Supported: yes Active: yes 2900 MHz max turbo 4 active cores 2900 MHz max turbo 3 active cores 2900 MHz max turbo 2 active cores 3100 MHz max turbo 1 active cores idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 0: Number of idle states: 6 Available idle states: POLL C1-IVB C1E-IVB C3-IVB C6-IVB C7-IVB POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 18019 Duration: 772944 C1-IVB: Flags/Description: MWAIT 0x00 Latency: 1 Usage: 263063 Duration: 84520314 C1E-IVB: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 148090 Duration: 51329106 C3-IVB: Flags/Description: MWAIT 0x10 Latency: 59 Usage: 48213 Duration: 21173996 C6-IVB: Flags/Description: MWAIT 0x20 Latency: 80 Usage: 2002 Duration: 5721448 C7-IVB: Flags/Description: MWAIT 0x30 Latency: 87 Usage: 440789 Duration: 1856576192
