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: 798 MHz - 1.86 GHz available frequency steps: 1.86 GHz, 1.60 GHz, 1.33 GHz, 1.06 GHz, 798 MHz available cpufreq governors: userspace, ondemand, performance current policy: frequency should be within 798 MHz and 1.86 GHz. The governor "ondemand" may decide which speed to use within this range. current CPU frequency is 798 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: 5 Available idle states: POLL C1E-ATM C2-ATM C4-ATM C6-ATM POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 4514 Duration: 1329970 C1E-ATM: Flags/Description: MWAIT 0x00 Latency: 10 Usage: 1754721 Duration: 200743715 C2-ATM: Flags/Description: MWAIT 0x10 Latency: 20 Usage: 1135122 Duration: 521791856 C4-ATM: Flags/Description: MWAIT 0x30 Latency: 100 Usage: 686639 Duration: 510519818 C6-ATM: Flags/Description: MWAIT 0x52 Latency: 140 Usage: 6546919 Duration: 18080335462
