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: 1.60 GHz - 3.90 GHz available cpufreq governors: performance, powersave current policy: frequency should be within 1.60 GHz and 3.90 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency is 2.51 GHz (asserted by call to hardware). 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-IVB C1E-IVB C3-IVB C6-IVB POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 2166 Duration: 241803 C1-IVB: Flags/Description: MWAIT 0x00 Latency: 1 Usage: 28223 Duration: 6362798 C1E-IVB: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 55134 Duration: 30829181 C3-IVB: Flags/Description: MWAIT 0x10 Latency: 59 Usage: 19357 Duration: 15969823 C6-IVB: Flags/Description: MWAIT 0x20 Latency: 80 Usage: 108746 Duration: 338184250
