The governor "ondemand" may decide which speed to use within this range. current CPU frequency: 1.60 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 C2 C4 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 39151 Duration: 1389589 C1E: Flags/Description: MWAIT 0x00 Latency: 10 Usage: 116579 Duration: 87623466 C2: Flags/Description: MWAIT 0x10 Latency: 20 Usage: 127225 Duration: 53351149 C4: Flags/Description: MWAIT 0x30 Latency: 100 Usage: 651293 Duration: 480490468
