frequency-info -------------- analyzing CPU 0: driver: acpi-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 - 2.26 GHz available frequency steps: 2.26 GHz, 2.26 GHz, 2.13 GHz, 2.00 GHz, 1.86 GHz, 1.73 GHz, 1.60 GHz available cpufreq governors: conservative ondemand userspace powersave performance schedutil current policy: frequency should be within 1.60 GHz and 2.26 GHz. The governor "ondemand" may decide which speed to use within this range. current CPU frequency: 1.86 GHz (asserted by call to hardware) boost state support: Supported: yes Active: yes 2400 MHz max turbo 4 active cores 2400 MHz max turbo 3 active cores 2533 MHz max turbo 2 active cores 2533 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: 3983226 Duration: 62959441 C1: Flags/Description: MWAIT 0x00 Latency: 3 Usage: 64730438 Duration: 2431976750 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 18725516 Duration: 2079773705 C3: Flags/Description: MWAIT 0x10 Latency: 20 Usage: 124886976 Duration: 60049666526 C6: Flags/Description: MWAIT 0x20 Latency: 200 Usage: 513751394 Duration: 952517133327
