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 1.34 GHz (asserted by call to hardware). boost state support: Supported: yes Active: yes 2600 MHz max turbo 4 active cores 2600 MHz max turbo 3 active cores 2800 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: 541 Duration: 449032 C1-SNB: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 56711 Duration: 13613391 C1E-SNB: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 211581 Duration: 93869341 C3-SNB: Flags/Description: MWAIT 0x10 Latency: 80 Usage: 51304 Duration: 29567148 C6-SNB: Flags/Description: MWAIT 0x20 Latency: 104 Usage: 758 Duration: 1360076 C7-SNB: Flags/Description: MWAIT 0x30 Latency: 109 Usage: 461328 Duration: 926550422
