frequency-info -------------- analyzing CPU 0: driver: intel_cpufreq CPUs which run at the same hardware frequency: 0 CPUs which need to have their frequency coordinated by software: 0 maximum transition latency: 20.0 us hardware limits: 1.33 GHz - 2.58 GHz available cpufreq governors: conservative ondemand userspace powersave performance schedutil current policy: frequency should be within 1.33 GHz and 2.58 GHz. The governor "ondemand" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 2.58 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: 6 Available idle states: POLL C1 C6N C6S C7 C7S POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 4543 Duration: 27227 C1: Flags/Description: MWAIT 0x00 Latency: 1 Usage: 638639 Duration: 70815290 C6N: Flags/Description: MWAIT 0x58 Latency: 300 Usage: 83494 Duration: 33691631 C6S: Flags/Description: MWAIT 0x52 Latency: 500 Usage: 166618 Duration: 160273306 C7: Flags/Description: MWAIT 0x60 Latency: 1200 Usage: 35759 Duration: 153179076 C7S: Flags/Description: MWAIT 0x64 Latency: 10000 Usage: 8135 Duration: 272401875
