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: 933 MHz - 1.87 GHz available frequency steps: 1.87 GHz, 1.73 GHz, 1.60 GHz, 1.47 GHz, 1.33 GHz, 1.20 GHz, 1.07 GHz, 933 MHz available cpufreq governors: userspace, ondemand, performance current policy: frequency should be within 933 MHz and 1.87 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: no Active: no 25500 MHz max turbo 4 active cores 25500 MHz max turbo 3 active cores 25500 MHz max turbo 2 active cores 25500 MHz max turbo 1 active cores idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu Analyzing CPU 0: Number of idle states: 4 Available idle states: POLL C1-NHM C1E-NHM C3-NHM POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 6233 Duration: 1734565 C1-NHM: Flags/Description: MWAIT 0x00 Latency: 3 Usage: 328209 Duration: 61626448 C1E-NHM: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 331505 Duration: 69347697 C3-NHM: Flags/Description: MWAIT 0x10 Latency: 20 Usage: 3309076 Duration: 9292218849
