The governor "ondemand" may decide which speed to use within this range. current CPU frequency: 1.87 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: 833 Duration: 7028 C1: Flags/Description: ACPI HLT Latency: 1 Usage: 0 Duration: 0 C2: Flags/Description: ACPI IOPORT 0x1014 Latency: 1 Usage: 17756 Duration: 108010612 C3: Flags/Description: ACPI IOPORT 0x1015 Latency: 85 Usage: 42 Duration: 4154 C4: Flags/Description: ACPI IOPORT 0x1016 Latency: 185 Usage: 604 Duration: 145604
