The governor "ondemand" may decide which speed to use within this range. current CPU frequency: 800 MHz (asserted by call to hardware) boost state support: Supported: yes Active: yes 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: 17922 Duration: 848368 C1_ACPI: Flags/Description: ACPI FFH MWAIT 0x0 Latency: 1 Residency: 1 Usage: 540 Duration: 172427 C2_ACPI: Flags/Description: ACPI FFH MWAIT 0x10 Latency: 1 Residency: 3 Usage: 219788 Duration: 94689248 C3_ACPI: Flags/Description: ACPI FFH MWAIT 0x20 Latency: 17 Residency: 51 Usage: 4877131 Duration: 199101351
