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: 1000 MHz - 1.67 GHz available frequency steps: 1.67 GHz, 1.33 GHz, 1000 MHz available cpufreq governors: userspace, ondemand, performance current policy: frequency should be within 1000 MHz and 1.67 GHz. The governor "ondemand" may decide which speed to use within this range. current CPU frequency is 1.67 GHz (asserted by call to hardware). boost state support: Supported: no Active: no idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu Analyzing CPU 0: Number of idle states: 4 Available idle states: POLL C1E-ATM C2-ATM C4-ATM POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 582 Duration: 233558 C1E-ATM: Flags/Description: MWAIT 0x00 Latency: 10 Usage: 45316 Duration: 13273904 C2-ATM: Flags/Description: MWAIT 0x10 Latency: 20 Usage: 222294 Duration: 105511276 C4-ATM: Flags/Description: MWAIT 0x30 Latency: 100 Usage: 350882 Duration: 976185104
