frequency-info -------------- analyzing CPU 3: driver: acpi-cpufreq CPUs which run at the same hardware frequency: 3 CPUs which need to have their frequency coordinated by software: 3 maximum transition latency: 10.0 us hardware limits: 1.20 GHz - 2.13 GHz available frequency steps: 2.13 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 2.13 GHz. The governor "schedutil" may decide which speed to use within this range. current CPU frequency: 1.20 GHz (asserted by call to hardware) boost state support: Supported: yes Active: yes 2667 MHz max turbo 2 active cores 2933 MHz max turbo 1 active cores idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 2: Number of idle states: 5 Available idle states: POLL C1 C1E C3 C6 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 248423 Duration: 4814623 C1: Flags/Description: MWAIT 0x00 Latency: 3 Usage: 549699 Duration: 93765572 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 1453329 Duration: 217246517 C3: Flags/Description: MWAIT 0x10 Latency: 20 Usage: 3625433 Duration: 1502692194 C6: Flags/Description: MWAIT 0x20 Latency: 200 Usage: 9053449 Duration: 41366294518
