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: 0.97 ms. 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 is 2.90 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: 678 Duration: 765109 C1-IVB: Flags/Description: MWAIT 0x00 Latency: 1 Usage: 89307 Duration: 34100202 C1E-IVB: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 207148 Duration: 233274500 C3-IVB: Flags/Description: MWAIT 0x10 Latency: 59 Usage: 50113 Duration: 27939158 C6-IVB: Flags/Description: MWAIT 0x20 Latency: 80 Usage: 1990 Duration: 3282176 C7-IVB: Flags/Description: MWAIT 0x30 Latency: 87 Usage: 665999 Duration: 2914700958
