frequency-info -------------- analyzing CPU 3: driver: intel_cpufreq CPUs which run at the same hardware frequency: 3 CPUs which need to have their frequency coordinated by software: 3 maximum transition latency: 20.0 us hardware limits: 500 MHz - 2.90 GHz available cpufreq governors: conservative ondemand userspace powersave performance schedutil current policy: frequency should be within 500 MHz and 2.90 GHz. The governor "ondemand" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 2.44 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: 134141 Duration: 1533159 C1: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 69588 Duration: 10112012 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 79335 Duration: 8546465 C3: Flags/Description: MWAIT 0x10 Latency: 40 Usage: 47193 Duration: 15030950 C6: Flags/Description: MWAIT 0x20 Latency: 133 Usage: 16380 Duration: 9711126 C7s: Flags/Description: MWAIT 0x32 Latency: 166 Usage: 37007 Duration: 22373282 C8: Flags/Description: MWAIT 0x40 Latency: 300 Usage: 25007 Duration: 21664133 C9: Flags/Description: MWAIT 0x50 Latency: 600 Usage: 142557 Duration: 173698736 C10: Flags/Description: MWAIT 0x60 Latency: 2600 Usage: 47628 Duration: 106950871
