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: 1.20 GHz - 2.20 GHz available frequency steps: 2.20 GHz, 2.20 GHz, 1.60 GHz, 1.20 GHz available cpufreq governors: userspace, ondemand, performance current policy: frequency should be within 1.20 GHz and 2.20 GHz. The governor "ondemand" may decide which speed to use within this range. current CPU frequency is 2.20 GHz (asserted by call to hardware). boost state support: Supported: yes Active: yes idle-info --------- CPUidle driver: acpi_idle CPUidle governor: menu Analyzing CPU 0: Number of idle states: 3 Available idle states: POLL C1 C2 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 547 Duration: 204068 C1: Flags/Description: ACPI FFH INTEL MWAIT 0x0 Latency: 1 Usage: 174121 Duration: 87103935 C2: Flags/Description: ACPI FFH INTEL MWAIT 0x30 Latency: 57 Usage: 1297029 Duration: 6076969592
