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: 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: 1.79 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: 34324 Duration: 429476 C1: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 54486 Duration: 4370303 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 61738 Duration: 28548918 C3: Flags/Description: MWAIT 0x10 Latency: 40 Usage: 135 Duration: 20193 C6: Flags/Description: MWAIT 0x20 Latency: 133 Usage: 27513 Duration: 39797259 C7s: Flags/Description: MWAIT 0x32 Latency: 166 Usage: 25149 Duration: 52855946 C8: Flags/Description: MWAIT 0x40 Latency: 300 Usage: 13068 Duration: 42545135 C9: Flags/Description: MWAIT 0x50 Latency: 600 Usage: 3360 Duration: 16868790 C10: Flags/Description: MWAIT 0x60 Latency: 2600 Usage: 13353 Duration: 204348044
