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: 800 MHz - 2.60 GHz available cpufreq governors: performance, powersave current policy: frequency should be within 800 MHz and 2.60 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency is 1.30 GHz (asserted by call to hardware). boost state support: Supported: yes Active: yes 2400 MHz max turbo 4 active cores 2400 MHz max turbo 3 active cores 2400 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: 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: 620 Duration: 504222 C1-IVB: Flags/Description: MWAIT 0x00 Latency: 1 Usage: 158447 Duration: 38993029 C1E-IVB: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 287077 Duration: 90739631 C3-IVB: Flags/Description: MWAIT 0x10 Latency: 59 Usage: 158736 Duration: 97811903 C6-IVB: Flags/Description: MWAIT 0x20 Latency: 80 Usage: 34107 Duration: 46987632 C7-IVB: Flags/Description: MWAIT 0x30 Latency: 87 Usage: 835603 Duration: 4760479885
