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: 481 Duration: 454782 C1E-ATM: Flags/Description: MWAIT 0x00 Latency: 10 Usage: 143387 Duration: 55695436 C2-ATM: Flags/Description: MWAIT 0x10 Latency: 20 Usage: 101048 Duration: 61526279 C4-ATM: Flags/Description: MWAIT 0x30 Latency: 100 Usage: 1141174 Duration: 2577076807
