The governor "ondemand" may decide which speed to use within this range. current CPU frequency: 1.33 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: 4 Available idle states: POLL C1 C2 C3 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 453 Duration: 416477 C1: Flags/Description: ACPI FFH INTEL MWAIT 0x0 Latency: 1 Usage: 1225 Duration: 216081 C2: Flags/Description: ACPI FFH INTEL MWAIT 0x10 Latency: 1 Usage: 163404 Duration: 71745961 C3: Flags/Description: ACPI FFH INTEL MWAIT 0x30 Latency: 57 Usage: 356204 Duration: 218018768
