frequency-info -------------- analyzing CPU 7: driver: acpi-cpufreq CPUs which run at the same hardware frequency: 7 CPUs which need to have their frequency coordinated by software: 7 maximum transition latency: 10.0 us hardware limits: 1.20 GHz - 2.80 GHz available frequency steps: 2.80 GHz, 2.80 GHz, 2.67 GHz, 2.53 GHz, 2.40 GHz, 2.27 GHz, 2.13 GHz, 2.00 GHz, 1.87 GHz, 1.73 GHz, 1.60 GHz, 1.47 GHz, 1.33 GHz, 1.20 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: 2.80 GHz (asserted by call to hardware) boost state support: Supported: yes Active: yes 2933 MHz max turbo 4 active cores 2933 MHz max turbo 3 active cores 3333 MHz max turbo 2 active cores 3467 MHz max turbo 1 active cores idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 7: Number of idle states: 5 Available idle states: POLL C1 C1E C3 C6 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Residency: 0 Usage: 34333 Duration: 567672 C1: Flags/Description: MWAIT 0x00 Latency: 3 Residency: 6 Usage: 10950 Duration: 751313 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Residency: 20 Usage: 34867 Duration: 2264704 C3: Flags/Description: MWAIT 0x10 Latency: 20 Residency: 80 Usage: 26736 Duration: 9566193 C6: Flags/Description: MWAIT 0x20 Latency: 200 Residency: 800 Usage: 44523 Duration: 434488829
