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: Cannot determine or is not supported. 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: 2.19 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: 210 Duration: 460929 C1-BYT: Flags/Description: MWAIT 0x00 Latency: 1 Usage: 37619 Duration: 37913785 C6N-BYT: Flags/Description: MWAIT 0x58 Latency: 300 Usage: 9010 Duration: 15244392 C6S-BYT: Flags/Description: MWAIT 0x52 Latency: 500 Usage: 21328 Duration: 55599836 C7-BYT: Flags/Description: MWAIT 0x60 Latency: 1200 Usage: 7093 Duration: 44258065 C7S-BYT: Flags/Description: MWAIT 0x64 Latency: 10000 Usage: 1652 Duration: 23621195
