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 - 2.70 GHz available cpufreq governors: conservative ondemand userspace powersave performance schedutil current policy: frequency should be within 500 MHz and 2.70 GHz. The governor "ondemand" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 2.00 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: 29191 Duration: 735487 C1: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 47234 Duration: 4331737 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 50971 Duration: 23651225 C3: Flags/Description: MWAIT 0x10 Latency: 40 Usage: 986 Duration: 465732 C6: Flags/Description: MWAIT 0x20 Latency: 133 Usage: 14843 Duration: 20013624 C7s: Flags/Description: MWAIT 0x32 Latency: 166 Usage: 15903 Duration: 34731921 C8: Flags/Description: MWAIT 0x40 Latency: 300 Usage: 10062 Duration: 35341726 C9: Flags/Description: MWAIT 0x50 Latency: 600 Usage: 3438 Duration: 15560599 C10: Flags/Description: MWAIT 0x60 Latency: 2600 Usage: 13787 Duration: 253971045
