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 - 1.90 GHz available cpufreq governors: performance powersave current policy: frequency should be within 1.20 GHz and 1.90 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: 1.52 GHz (asserted by call to hardware) boost state support: Supported: no Active: no 1900 MHz max turbo 4 active cores 1900 MHz max turbo 3 active cores 1900 MHz max turbo 2 active cores 1900 MHz max turbo 1 active cores idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 0: Number of idle states: 4 Available idle states: POLL C1-IVB C1E-IVB C3-IVB POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 1089 Duration: 556949 C1-IVB: Flags/Description: MWAIT 0x00 Latency: 1 Usage: 142084 Duration: 57060484 C1E-IVB: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 244320 Duration: 148474221 C3-IVB: Flags/Description: MWAIT 0x10 Latency: 59 Usage: 588330 Duration: 1599244913
