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 - 2.53 GHz available frequency steps: 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, 1.07 GHz, 933 MHz available cpufreq governors: userspace, ondemand, performance current policy: frequency should be within 933 MHz and 2.53 GHz. The governor "ondemand" may decide which speed to use within this range. current CPU frequency is 2.53 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: 5 Available idle states: POLL C1-NHM C1E-NHM C3-NHM C6-NHM POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 4446 Duration: 410491 C1-NHM: Flags/Description: MWAIT 0x00 Latency: 3 Usage: 926458 Duration: 78636149 C1E-NHM: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 455921 Duration: 31902783 C3-NHM: Flags/Description: MWAIT 0x10 Latency: 20 Usage: 167825 Duration: 125319304 C6-NHM: Flags/Description: MWAIT 0x20 Latency: 200 Usage: 83175 Duration: 253002117
