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: 800 MHz - 2.90 GHz available cpufreq governors: conservative ondemand userspace powersave performance schedutil current policy: frequency should be within 800 MHz and 2.90 GHz. The governor "schedutil" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 1.90 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 3: 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: 4708 Duration: 93440 C1: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 28390 Duration: 3785904 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 64794 Duration: 8211006 C3: Flags/Description: MWAIT 0x10 Latency: 33 Usage: 123771 Duration: 35748290 C6: Flags/Description: MWAIT 0x20 Latency: 133 Usage: 41144 Duration: 19830362 C7s: Flags/Description: MWAIT 0x32 Latency: 166 Usage: 220778 Duration: 166844107 C8: Flags/Description: MWAIT 0x40 Latency: 300 Usage: 26149 Duration: 20332937 C9: Flags/Description: MWAIT 0x50 Latency: 600 Usage: 198399 Duration: 698284847 C10: Flags/Description: MWAIT 0x60 Latency: 2600 Usage: 64401 Duration: 921090388
