The governor "ondemand" may decide which speed to use within this range. current CPU frequency: 1.67 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 C1E-ATM C2-ATM C4-ATM POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 1466 Duration: 746244 C1E-ATM: Flags/Description: MWAIT 0x00 Latency: 10 Usage: 36620 Duration: 13657433 C2-ATM: Flags/Description: MWAIT 0x10 Latency: 20 Usage: 228828 Duration: 122721455 C4-ATM: Flags/Description: MWAIT 0x30 Latency: 100 Usage: 429132 Duration: 253305989
