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: 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: userspace, ondemand, performance 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 is 1.20 GHz (asserted by call to hardware). boost state support: Supported: yes Active: yes 2200 MHz max turbo 4 active cores 2200 MHz max turbo 3 active cores 2500 MHz max turbo 2 active cores 2500 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-NHM C1E-NHM C3-NHM C6-NHM POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 540 Duration: 124814 C1-NHM: Flags/Description: MWAIT 0x00 Latency: 3 Usage: 21965 Duration: 2718036 C1E-NHM: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 15187 Duration: 4768204 C3-NHM: Flags/Description: MWAIT 0x10 Latency: 20 Usage: 136153 Duration: 108684348 C6-NHM: Flags/Description: MWAIT 0x20 Latency: 200 Usage: 127775 Duration: 355576684
