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 - 3.20 GHz available cpufreq governors: performance powersave current policy: frequency should be within 1.60 GHz and 3.20 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: 1.87 GHz (asserted by call to hardware) boost state support: Supported: yes Active: yes 3000 MHz max turbo 4 active cores 3100 MHz max turbo 3 active cores 3200 MHz max turbo 2 active cores 3200 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-IVB C1E-IVB C3-IVB C6-IVB POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 325 Duration: 900833 C1-IVB: Flags/Description: MWAIT 0x00 Latency: 1 Usage: 37313 Duration: 18718095 C1E-IVB: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 58660 Duration: 47551994 C3-IVB: Flags/Description: MWAIT 0x10 Latency: 59 Usage: 14220 Duration: 11097235 C6-IVB: Flags/Description: MWAIT 0x20 Latency: 80 Usage: 135530 Duration: 647445193
