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 - 1.90 GHz available cpufreq governors: performance powersave current policy: frequency should be within 500 MHz and 1.90 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 1.23 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: 350 Duration: 566329 C1: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 57616 Duration: 25240225 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 33612 Duration: 16325793 C3: Flags/Description: MWAIT 0x10 Latency: 40 Usage: 96335 Duration: 47403707 C6: Flags/Description: MWAIT 0x20 Latency: 133 Usage: 29595 Duration: 20072433 C7s: Flags/Description: MWAIT 0x32 Latency: 166 Usage: 72381 Duration: 73245458 C8: Flags/Description: MWAIT 0x40 Latency: 300 Usage: 75002 Duration: 118738178 C9: Flags/Description: MWAIT 0x50 Latency: 600 Usage: 91898 Duration: 383199842 C10: Flags/Description: MWAIT 0x60 Latency: 2600 Usage: 31320 Duration: 716971342
