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: 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: Unable to call hardware current CPU frequency: 2.19 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 0: Number of idle states: 9 Available idle states: POLL C1 C1E C3 C6 C7s C8 C9 C10 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 21941 Duration: 16779393 C1: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 2810488 Duration: 1077517093 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 2551171 Duration: 497299839 C3: Flags/Description: MWAIT 0x10 Latency: 33 Usage: 4738207 Duration: 1819708534 C6: Flags/Description: MWAIT 0x20 Latency: 133 Usage: 1289196 Duration: 796016482 C7s: Flags/Description: MWAIT 0x32 Latency: 166 Usage: 4287657 Duration: 4160347322 C8: Flags/Description: MWAIT 0x40 Latency: 300 Usage: 2389902 Duration: 3165330009 C9: Flags/Description: MWAIT 0x50 Latency: 600 Usage: 2417711 Duration: 6970271265 C10: Flags/Description: MWAIT 0x60 Latency: 2600 Usage: 412315 Duration: 4187709421
