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 - 2.60 GHz available cpufreq governors: performance, powersave current policy: frequency should be within 1.60 GHz and 2.60 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency is 2.22 GHz (asserted by call to hardware). boost state support: Supported: no Active: no 2600 MHz max turbo 4 active cores 2600 MHz max turbo 3 active cores 2600 MHz max turbo 2 active cores 2600 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-SNB C1E-SNB C3-SNB C6-SNB POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 1432 Duration: 454302 C1-SNB: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 555012 Duration: 22640482 C1E-SNB: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 170856 Duration: 104239788 C3-SNB: Flags/Description: MWAIT 0x10 Latency: 80 Usage: 55128 Duration: 36016167 C6-SNB: Flags/Description: MWAIT 0x20 Latency: 104 Usage: 712162 Duration: 2281486925
