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: 800 MHz - 1.60 GHz available frequency steps: 1.60 GHz, 1.33 GHz, 1.07 GHz, 800 MHz available cpufreq governors: userspace, ondemand, performance current policy: frequency should be within 800 MHz and 1.60 GHz. The governor "ondemand" may decide which speed to use within this range. current CPU frequency is 800 MHz (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: 452 Duration: 211686 C1E-ATM: Flags/Description: MWAIT 0x00 Latency: 10 Usage: 105704 Duration: 291967727 C2-ATM: Flags/Description: MWAIT 0x10 Latency: 20 Usage: 217632 Duration: 161740050 C4-ATM: Flags/Description: MWAIT 0x30 Latency: 100 Usage: 771157 Duration: 1254325412
