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 "schedutil" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 2.12 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: 1647834 Duration: 8508828 C1: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 12155054 Duration: 876889621 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 14035194 Duration: 1479818228 C3: Flags/Description: MWAIT 0x10 Latency: 40 Usage: 22440122 Duration: 5610674549 C6: Flags/Description: MWAIT 0x20 Latency: 133 Usage: 5680552 Duration: 2524915938 C7s: Flags/Description: MWAIT 0x32 Latency: 166 Usage: 14469820 Duration: 8581050656 C8: Flags/Description: MWAIT 0x40 Latency: 300 Usage: 4463166 Duration: 3003175151 C9: Flags/Description: MWAIT 0x50 Latency: 600 Usage: 12984621 Duration: 27493268388 C10: Flags/Description: MWAIT 0x60 Latency: 2600 Usage: 1479428 Duration: 16397721468
