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: 1.20 GHz - 4.20 GHz available cpufreq governors: conservative ondemand userspace powersave performance schedutil current policy: frequency should be within 2.00 GHz and 4.20 GHz. The governor "ondemand" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 2.48 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: 5 Available idle states: POLL C1 C1E C3 C6 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 20279927 Duration: 196296135 C1: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 67873410 Duration: 8448422786 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 42084791 Duration: 9022768630 C3 (DISABLED) : Flags/Description: MWAIT 0x10 Latency: 40 Usage: 0 Duration: 0 C6: Flags/Description: MWAIT 0x20 Latency: 133 Usage: 64866527 Duration: 67537165021
