frequency-info -------------- analyzing CPU 1: driver: intel_cpufreq CPUs which run at the same hardware frequency: 1 CPUs which need to have their frequency coordinated by software: 1 maximum transition latency: 20.0 us hardware limits: 1.20 GHz - 1.90 GHz available cpufreq governors: conservative ondemand userspace powersave performance schedutil current policy: frequency should be within 1.20 GHz and 1.90 GHz. The governor "ondemand" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 1.51 GHz (asserted by call to kernel) boost state support: Supported: no Active: no 1900 MHz max turbo 4 active cores 1900 MHz max turbo 3 active cores 1900 MHz max turbo 2 active cores 1900 MHz max turbo 1 active cores idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 1: Number of idle states: 4 Available idle states: POLL C1 C1E C3 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Residency: 0 Usage: 5395 Duration: 66820 C1: Flags/Description: MWAIT 0x00 Latency: 1 Residency: 1 Usage: 17645 Duration: 2384759 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Residency: 20 Usage: 29648 Duration: 5161685 C3: Flags/Description: MWAIT 0x10 Latency: 59 Residency: 156 Usage: 158278 Duration: 343991872
