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 - 2.13 GHz available frequency steps: 2.13 GHz, 2.00 GHz, 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 2.13 GHz. The governor "ondemand" may decide which speed to use within this range. current CPU frequency is 2.13 GHz (asserted by call to hardware). boost state support: Supported: no Active: no 1600 MHz max turbo 2 active cores 1600 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: 107 Duration: 83779 C1-NHM: Flags/Description: MWAIT 0x00 Latency: 3 Usage: 13961 Duration: 6072364 C1E-NHM: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 6636 Duration: 5405168 C3-NHM: Flags/Description: MWAIT 0x10 Latency: 20 Usage: 65091 Duration: 235095351
