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 1.68 GHz (asserted by call to hardware). boost state support: Supported: yes Active: yes 3700 MHz max turbo 4 active cores 3800 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: 260 Duration: 133989 C1-IVB: Flags/Description: MWAIT 0x00 Latency: 1 Usage: 37998 Duration: 4587839 C1E-IVB: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 72926 Duration: 19058404 C3-IVB: Flags/Description: MWAIT 0x10 Latency: 59 Usage: 31236 Duration: 10607373 C6-IVB: Flags/Description: MWAIT 0x20 Latency: 80 Usage: 388214 Duration: 977201898
