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: 500 MHz - 2.67 GHz available cpufreq governors: performance, powersave current policy: frequency should be within 500 MHz and 2.67 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency is 2.67 GHz (asserted by call to hardware). boost state support: Supported: yes Active: yes idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu Analyzing CPU 0: Number of idle states: 6 Available idle states: POLL C1-BYT C6N-BYT C6S-BYT C7-BYT C7S-BYT POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 3721 Duration: 907423 C1-BYT: Flags/Description: MWAIT 0x00 Latency: 1 Usage: 78359 Duration: 52779802 C6N-BYT: Flags/Description: MWAIT 0x58 Latency: 300 Usage: 21916 Duration: 21848163 C6S-BYT: Flags/Description: MWAIT 0x52 Latency: 500 Usage: 82711 Duration: 169201390 C7-BYT: Flags/Description: MWAIT 0x60 Latency: 1200 Usage: 18255 Duration: 127080446 C7S-BYT: Flags/Description: MWAIT 0x64 Latency: 10000 Usage: 4370 Duration: 95029256
