The governor "conservative" may decide which speed to use within this range. current CPU frequency: 3.66 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 0: Number of idle states: 6 Available idle states: POLL C1 C1E C3 C6 C7s POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Residency: 0 Usage: 289504 Duration: 1386391 C1: Flags/Description: MWAIT 0x00 Latency: 2 Residency: 2 Usage: 2223158 Duration: 122099383 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Residency: 20 Usage: 1963951 Duration: 235603605 C3: Flags/Description: MWAIT 0x10 Latency: 33 Residency: 100 Usage: 2608818 Duration: 674455247 C6: Flags/Description: MWAIT 0x20 Latency: 133 Residency: 400 Usage: 285504 Duration: 132832081 C7s: Flags/Description: MWAIT 0x32 Latency: 166 Residency: 500 Usage: 1192155 Duration: 1097290392
