The governor "ondemand" may decide which speed to use within this range. current CPU frequency: 1.66 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: 3 Available idle states: POLL C1 C2 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 937 Duration: 331740 C1: Flags/Description: ACPI HLT Latency: 1 Usage: 12410 Duration: 398289 C2: Flags/Description: ACPI IOPORT 0x814 Latency: 1 Usage: 2707118 Duration: 4247469474
