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 - 2.80 GHz available cpufreq governors: conservative ondemand userspace powersave performance schedutil current policy: frequency should be within 1.20 GHz and 2.80 GHz. The governor "ondemand" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 2.21 GHz (asserted by call to kernel) boost state support: Supported: no Active: no 2800 MHz max turbo 4 active cores 2800 MHz max turbo 3 active cores 2800 MHz max turbo 2 active cores 2800 MHz max turbo 1 active cores idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 0: Number of idle states: 6 Available idle states: POLL C1 C1E C3 C6 C7 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 2918238660 Duration: 4072002455 C1: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 205058690 Duration: 15804158225 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 2087393248 Duration: 563701744303 C3 (DISABLED) : Flags/Description: MWAIT 0x10 Latency: 80 Usage: 0 Duration: 0 C6: Flags/Description: MWAIT 0x20 Latency: 104 Usage: 1058825 Duration: 373291933 C7: Flags/Description: MWAIT 0x30 Latency: 109 Usage: 2206143427 Duration: 816661498461
