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: 800 MHz - 3.10 GHz available cpufreq governors: performance schedutil current policy: frequency should be within 800 MHz and 3.10 GHz. The governor "schedutil" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 2.56 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes 2900 MHz max turbo 4 active cores 2900 MHz max turbo 3 active cores 2900 MHz max turbo 2 active cores 3100 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: 54410 Duration: 1049345 C1: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 166527 Duration: 24316079 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 849632 Duration: 262212355 C3: Flags/Description: MWAIT 0x10 Latency: 80 Usage: 337867 Duration: 151551448 C6: Flags/Description: MWAIT 0x20 Latency: 104 Usage: 6921 Duration: 10618452 C7: Flags/Description: MWAIT 0x30 Latency: 109 Usage: 4399365 Duration: 19479933916
