frequency-info -------------- analyzing CPU 23: driver: intel_pstate CPUs which run at the same hardware frequency: 23 CPUs which need to have their frequency coordinated by software: 23 maximum transition latency: Cannot determine or is not supported. hardware limits: 800 MHz - 3.90 GHz available cpufreq governors: performance powersave current policy: frequency should be within 800 MHz and 3.90 GHz. The governor "performance" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 3.82 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 23: Number of idle states: 5 Available idle states: POLL C1E C6 C8 C10 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 2598 Duration: 22965 C1E: Flags/Description: MWAIT 0x01 Latency: 2 Usage: 4744 Duration: 1046297 C6: Flags/Description: MWAIT 0x20 Latency: 220 Usage: 2713 Duration: 2482967 C8: Flags/Description: MWAIT 0x40 Latency: 280 Usage: 98 Duration: 95487 C10: Flags/Description: MWAIT 0x60 Latency: 680 Usage: 3708 Duration: 219526421
