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 - 4.30 GHz available cpufreq governors: performance powersave current policy: frequency should be within 800 MHz and 4.30 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 3.82 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 5: Number of idle states: 5 Available idle states: POLL C1E C6 C8 C10 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Residency: 0 Usage: 8595123 Duration: 277020746 C1E: Flags/Description: MWAIT 0x01 Latency: 2 Residency: 4 Usage: 81444460 Duration: 30461049063 C6: Flags/Description: MWAIT 0x20 Latency: 220 Residency: 600 Usage: 16103835 Duration: 15773641896 C8: Flags/Description: MWAIT 0x40 Latency: 280 Residency: 800 Usage: 18101098 Duration: 26540632739 C10: Flags/Description: MWAIT 0x60 Latency: 680 Residency: 2000 Usage: 38115371 Duration: 151752052465
