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 - 2.27 GHz available frequency steps: 2.27 GHz, 1.87 GHz, 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 2.27 GHz. The governor "ondemand" may decide which speed to use within this range. current CPU frequency is 2.27 GHz (asserted by call to hardware). boost state support: Supported: no Active: no idle-info --------- CPUidle driver: acpi_idle CPUidle governor: menu Analyzing CPU 0: Number of idle states: 5 Available idle states: POLL C1 C2 C3 C4 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 36 Duration: 6616 C1: Flags/Description: ACPI HLT Latency: 1 Usage: 451 Duration: 93933 C2: Flags/Description: ACPI IOPORT 0x1014 Latency: 1 Usage: 17313 Duration: 38447477 C3: Flags/Description: ACPI IOPORT 0x1015 Latency: 85 Usage: 1781 Duration: 5554759 C4: Flags/Description: ACPI IOPORT 0x1016 Latency: 185 Usage: 9248 Duration: 68612746
