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: 1.20 GHz - 3.10 GHz available cpufreq governors: performance, powersave current policy: frequency should be within 1.20 GHz and 3.10 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency is 2.84 GHz (asserted by call to hardware). boost state support: Supported: yes Active: yes 25500 MHz max turbo 4 active cores 25500 MHz max turbo 3 active cores 25500 MHz max turbo 2 active cores 25500 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: 38564 Duration: 4578985 C1-IVB: Flags/Description: MWAIT 0x00 Latency: 1 Usage: 15954177 Duration: 2701625830 C1E-IVB: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 12786081 Duration: 5265601131 C3-IVB: Flags/Description: MWAIT 0x10 Latency: 59 Usage: 2428682 Duration: 1269775628 C6-IVB: Flags/Description: MWAIT 0x20 Latency: 80 Usage: 210028 Duration: 187682990 C7-IVB: Flags/Description: MWAIT 0x30 Latency: 87 Usage: 7868095 Duration: 12765369201
