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 - 3.10 GHz available cpufreq governors: performance, powersave current policy: frequency should be within 1.60 GHz and 3.10 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency is 1.88 GHz (asserted by call to hardware). boost state support: Supported: yes Active: yes 2900 MHz max turbo 4 active cores 3000 MHz max turbo 3 active cores 3000 MHz max turbo 2 active cores 3100 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: 34715 Duration: 337876 C1-SNB: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 104082 Duration: 22171450 C1E-SNB: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 141847 Duration: 42605592 C3-SNB: Flags/Description: MWAIT 0x10 Latency: 80 Usage: 59645 Duration: 21557766 C6-SNB: Flags/Description: MWAIT 0x20 Latency: 104 Usage: 318095 Duration: 720335782
