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 - 3.00 GHz available cpufreq governors: conservative ondemand userspace powersave performance schedutil current policy: frequency should be within 500 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: 2.49 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: 33565 Duration: 86211 C1: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 52680 Duration: 2928536 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 32425 Duration: 3998785 C3: Flags/Description: MWAIT 0x10 Latency: 40 Usage: 26550 Duration: 6304787 C6: Flags/Description: MWAIT 0x20 Latency: 133 Usage: 7320 Duration: 3407981 C7s: Flags/Description: MWAIT 0x32 Latency: 166 Usage: 29124 Duration: 19630233 C8: Flags/Description: MWAIT 0x40 Latency: 300 Usage: 9311 Duration: 6401891 C9: Flags/Description: MWAIT 0x50 Latency: 600 Usage: 48344 Duration: 113282286 C10: Flags/Description: MWAIT 0x60 Latency: 2600 Usage: 16661 Duration: 225878080
