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: 1.60 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 available cpufreq governors: userspace, ondemand, performance current policy: frequency should be within 1.60 GHz and 2.13 GHz. The governor "ondemand" may decide which speed to use within this range. current CPU frequency is 1.87 GHz (asserted by call to hardware). boost state support: Supported: yes Active: yes 1700 MHz max turbo 4 active cores 1700 MHz max turbo 3 active cores 1800 MHz max turbo 2 active cores 1800 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: 122 Duration: 365512 C1-NHM: Flags/Description: MWAIT 0x00 Latency: 3 Usage: 10003 Duration: 2993931 C1E-NHM: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 9344 Duration: 4034685 C3-NHM: Flags/Description: MWAIT 0x10 Latency: 20 Usage: 85630 Duration: 64756094 C6-NHM: Flags/Description: MWAIT 0x20 Latency: 200 Usage: 37021 Duration: 137940117
