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 1.80 GHz (asserted by call to hardware). boost state support: Supported: yes Active: yes 3400 MHz max turbo 4 active cores 3500 MHz max turbo 3 active cores 3600 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-SNB C1E-SNB C3-SNB C6-SNB POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 699 Duration: 636011 C1-SNB: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 215869 Duration: 78760394 C1E-SNB: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 305925 Duration: 210707939 C3-SNB: Flags/Description: MWAIT 0x10 Latency: 80 Usage: 89252 Duration: 57346087 C6-SNB: Flags/Description: MWAIT 0x20 Latency: 104 Usage: 994915 Duration: 3367041710
