frequency-info -------------- analyzing CPU 4: driver: acpi-cpufreq CPUs which run at the same hardware frequency: 4 CPUs which need to have their frequency coordinated by software: 4 maximum transition latency: 10.0 us hardware limits: 1.20 GHz - 2.93 GHz available frequency steps: 2.93 GHz, 2.93 GHz, 2.79 GHz, 2.66 GHz, 2.53 GHz, 2.39 GHz, 2.26 GHz, 2.13 GHz, 2.00 GHz, 1.86 GHz, 1.73 GHz, 1.60 GHz, 1.46 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 2.93 GHz. The governor "schedutil" may decide which speed to use within this range. current CPU frequency: 2.00 GHz (asserted by call to hardware) boost state support: Supported: yes Active: yes 3200 MHz max turbo 4 active cores 3200 MHz max turbo 3 active cores 3467 MHz max turbo 2 active cores 3600 MHz max turbo 1 active cores idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 1: Number of idle states: 5 Available idle states: POLL C1 C1E C3 C6 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 122691 Duration: 1938066 C1: Flags/Description: MWAIT 0x00 Latency: 3 Usage: 184264 Duration: 4668070 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 8398 Duration: 955417 C3: Flags/Description: MWAIT 0x10 Latency: 20 Usage: 60186 Duration: 29712346 C6: Flags/Description: MWAIT 0x20 Latency: 200 Usage: 129568 Duration: 237036886
