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: yes Active: yes idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 0: Number of idle states: 9 Available idle states: POLL C1 C1E C3 C6 C7s C8 C9 C10 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 109303 Duration: 1864164 C1: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 1819802 Duration: 413301901 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 2679395 Duration: 761790245 C3: Flags/Description: MWAIT 0x10 Latency: 70 Usage: 1180342 Duration: 168215419 C6: Flags/Description: MWAIT 0x20 Latency: 85 Usage: 4691639 Duration: 1760043113 C7s: Flags/Description: MWAIT 0x33 Latency: 124 Usage: 1697 Duration: 561812 C8: Flags/Description: MWAIT 0x40 Latency: 200 Usage: 10771278 Duration: 10318108375 C9: Flags/Description: MWAIT 0x50 Latency: 480 Usage: 77675 Duration: 121715087 C10: Flags/Description: MWAIT 0x60 Latency: 890 Usage: 11584007 Duration: 71597204496
