The governor "ondemand" may decide which speed to use within this range. current CPU frequency: 1.47 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 Residency: 0 Usage: 81526 Duration: 3993393 C1_ACPI: Flags/Description: ACPI FFH MWAIT 0x0 Latency: 1 Residency: 1 Usage: 361 Duration: 69545 C2_ACPI: Flags/Description: ACPI FFH MWAIT 0x10 Latency: 1 Residency: 3 Usage: 182096 Duration: 57283333 C3_ACPI: Flags/Description: ACPI FFH MWAIT 0x20 Latency: 17 Residency: 51 Usage: 5708240 Duration: 165866693
