The governor "ondemand" may decide which speed to use within this range. current CPU frequency: 1.20 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: 9911 Duration: 508296 C1_ACPI: Flags/Description: ACPI FFH MWAIT 0x0 Latency: 1 Usage: 469 Duration: 3557 C2_ACPI: Flags/Description: ACPI FFH MWAIT 0x10 Latency: 1 Usage: 41901 Duration: 12791852 C3_ACPI: Flags/Description: ACPI FFH MWAIT 0x30 Latency: 57 Usage: 226704 Duration: 386846400
