The governor "ondemand" may decide which speed to use within this range. current CPU frequency: 600 MHz (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: 5 Available idle states: POLL C1E-ATM C2-ATM C4-ATM C6-ATM POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 299 Duration: 445282 C1E-ATM: Flags/Description: MWAIT 0x00 Latency: 10 Usage: 12543 Duration: 7134655 C2-ATM: Flags/Description: MWAIT 0x10 Latency: 20 Usage: 24476 Duration: 23499868 C4-ATM: Flags/Description: MWAIT 0x30 Latency: 100 Usage: 4942 Duration: 6068597 C6-ATM: Flags/Description: MWAIT 0x52 Latency: 140 Usage: 57763 Duration: 238809031
