The governor "ondemand" may decide which speed to use within this range. current CPU frequency: 1.20 GHz (asserted by call to hardware) idle-info --------- CPUidle driver: acpi_idle CPUidle governor: menu analyzing CPU 0: Number of idle states: 4 Available idle states: POLL C1 C2 C3 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 314 Duration: 3411 C1: Flags/Description: ACPI HLT Latency: 1 Usage: 24594 Duration: 5705580 C2: Flags/Description: ACPI IOPORT 0x814 Latency: 50 Usage: 4036 Duration: 722699 C3: Flags/Description: ACPI IOPORT 0x815 Latency: 80 Usage: 240884 Duration: 565278736
