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: 1.60 GHz - 2.60 GHz available cpufreq governors: conservative ondemand userspace powersave performance schedutil current policy: frequency should be within 1.60 GHz and 2.60 GHz. The governor "ondemand" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 2.57 GHz (asserted by call to kernel) boost state support: Supported: no Active: no 2600 MHz max turbo 4 active cores 2600 MHz max turbo 3 active cores 2600 MHz max turbo 2 active cores 2600 MHz max turbo 1 active cores 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: 12300 Duration: 22074 C1: Flags/Description: MWAIT 0x00 Latency: 1 Usage: 32770 Duration: 3184858 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 85534 Duration: 22516517 C3: Flags/Description: MWAIT 0x10 Latency: 59 Usage: 27448 Duration: 14175256 C6: Flags/Description: MWAIT 0x20 Latency: 80 Usage: 135856 Duration: 305932229
