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: 0.00 ms. hardware limits: 1.60 GHz - 2.40 GHz available cpufreq governors: performance, powersave current policy: frequency should be within 1.60 GHz and 2.40 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency is 1.89 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: 5 Available idle states: POLL C1-SNB C1E-SNB C3-SNB C6-SNB POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 643 Duration: 39746 C1-SNB: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 63087 Duration: 8768651 C1E-SNB: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 169082 Duration: 49544356 C3-SNB: Flags/Description: MWAIT 0x10 Latency: 80 Usage: 13740 Duration: 9352849 C6-SNB: Flags/Description: MWAIT 0x20 Latency: 104 Usage: 254063 Duration: 1521510094
