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 - 1.90 GHz available cpufreq governors: performance, powersave current policy: frequency should be within 1.20 GHz and 1.90 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency is 1.90 GHz (asserted by call to hardware). boost state support: Supported: no Active: no 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: 4 Available idle states: POLL C1-IVB C1E-IVB C3-IVB POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 78 Duration: 102293 C1-IVB: Flags/Description: MWAIT 0x00 Latency: 1 Usage: 18412 Duration: 5031191 C1E-IVB: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 15405 Duration: 13713558 C3-IVB: Flags/Description: MWAIT 0x10 Latency: 59 Usage: 19184 Duration: 70685510
