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 - 3.70 GHz available cpufreq governors: performance, powersave current policy: frequency should be within 1.60 GHz and 3.70 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency is 2.17 GHz (asserted by call to hardware). boost state support: Supported: yes Active: yes 3500 MHz max turbo 4 active cores 3600 MHz max turbo 3 active cores 3700 MHz max turbo 2 active cores 3700 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: 169 Duration: 304014 C1-IVB: Flags/Description: MWAIT 0x00 Latency: 1 Usage: 39235 Duration: 8941616 C1E-IVB: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 92558 Duration: 64436011 C3-IVB: Flags/Description: MWAIT 0x10 Latency: 59 Usage: 43087 Duration: 22923380 C6-IVB: Flags/Description: MWAIT 0x20 Latency: 80 Usage: 522144 Duration: 1395529351
