The governor "powersave" may decide which speed to use within this range. current CPU frequency: 2.80 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 1: Number of idle states: 7 Available idle states: POLL C1 C1E C3 C6 C7s C8 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Residency: 0 Usage: 122731 Duration: 2551731 C1: Flags/Description: MWAIT 0x00 Latency: 2 Residency: 2 Usage: 14454 Duration: 2099129 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Residency: 20 Usage: 42114 Duration: 5165602 C3: Flags/Description: MWAIT 0x10 Latency: 70 Residency: 100 Usage: 31630 Duration: 5316912 C6: Flags/Description: MWAIT 0x20 Latency: 85 Residency: 200 Usage: 167853 Duration: 94555282 C7s: Flags/Description: MWAIT 0x33 Latency: 124 Residency: 800 Usage: 0 Duration: 0 C8: Flags/Description: MWAIT 0x40 Latency: 200 Residency: 800 Usage: 76976 Duration: 252502044
