frequency-info -------------- analyzing CPU 4: driver: intel_cpufreq CPUs which run at the same hardware frequency: 4 CPUs which need to have their frequency coordinated by software: 4 maximum transition latency: 20.0 us hardware limits: 1.20 GHz - 3.10 GHz available cpufreq governors: conservative ondemand userspace powersave performance schedutil current policy: frequency should be within 1.20 GHz and 3.10 GHz. The governor "ondemand" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 1.49 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 21: Number of idle states: 5 Available idle states: POLL C1 C1E C3 C6 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Residency: 0 Usage: 783 Duration: 11318 C1: Flags/Description: MWAIT 0x00 Latency: 2 Residency: 2 Usage: 13262 Duration: 2415773 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Residency: 20 Usage: 30180 Duration: 6420823 C3 (DISABLED) : Flags/Description: MWAIT 0x10 Latency: 33 Residency: 100 Usage: 0 Duration: 0 C6: Flags/Description: MWAIT 0x20 Latency: 133 Residency: 400 Usage: 95943 Duration: 402327056
