frequency-info -------------- analyzing CPU 0: driver: intel_cpufreq CPUs which run at the same hardware frequency: 0 CPUs which need to have their frequency coordinated by software: 0 maximum transition latency: 20.0 us hardware limits: 800 MHz - 3.00 GHz available cpufreq governors: conservative ondemand userspace powersave performance schedutil current policy: frequency should be within 800 MHz and 3.00 GHz. The governor "ondemand" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 2.14 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: 9 Available idle states: POLL C1 C1E C3 C6 C7s C8 C9 C10 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 29226 Duration: 524816 C1: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 84415 Duration: 11790129 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 96935 Duration: 40811663 C3: Flags/Description: MWAIT 0x10 Latency: 33 Usage: 11367 Duration: 9478208 C6: Flags/Description: MWAIT 0x20 Latency: 133 Usage: 39123 Duration: 36573664 C7s: Flags/Description: MWAIT 0x32 Latency: 166 Usage: 30915 Duration: 34523560 C8: Flags/Description: MWAIT 0x40 Latency: 300 Usage: 79044 Duration: 125224841 C9: Flags/Description: MWAIT 0x50 Latency: 600 Usage: 29171 Duration: 77698076 C10: Flags/Description: MWAIT 0x60 Latency: 2600 Usage: 36151 Duration: 725416076
