The governor "ondemand" may decide which speed to use within this range. current CPU frequency: 1.60 GHz (asserted by call to hardware) boost state support: Supported: no Active: no idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 0: Number of idle states: 4 Available idle states: POLL C1_ACPI C2_ACPI C3_ACPI POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 34292 Duration: 823980 C1_ACPI: Flags/Description: ACPI FFH MWAIT 0x0 Latency: 1 Usage: 3711 Duration: 62432 C2_ACPI: Flags/Description: ACPI FFH MWAIT 0x10 Latency: 1 Usage: 85726 Duration: 36069133 C3_ACPI: Flags/Description: ACPI FFH MWAIT 0x20 Latency: 17 Usage: 13572999 Duration: 280932133
