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: 800 MHz - 2.90 GHz available cpufreq governors: performance, powersave current policy: frequency should be within 800 MHz and 2.90 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency is 1.08 GHz (asserted by call to hardware). boost state support: Supported: yes Active: yes 2700 MHz max turbo 4 active cores 2700 MHz max turbo 3 active cores 2700 MHz max turbo 2 active cores 2900 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-SNB C1E-SNB C3-SNB C6-SNB C7-SNB POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 419 Duration: 83371 C1-SNB: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 139568 Duration: 19633245 C1E-SNB: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 118648 Duration: 52417729 C3-SNB: Flags/Description: MWAIT 0x10 Latency: 80 Usage: 86040 Duration: 37521655 C6-SNB: Flags/Description: MWAIT 0x20 Latency: 104 Usage: 435 Duration: 685892 C7-SNB: Flags/Description: MWAIT 0x30 Latency: 109 Usage: 441852 Duration: 1401848132
