frequency-info -------------- analyzing CPU 12: driver: intel_pstate CPUs which run at the same hardware frequency: 12 CPUs which need to have their frequency coordinated by software: 12 maximum transition latency: Cannot determine or is not supported. hardware limits: 400 MHz - 3.50 GHz available cpufreq governors: performance powersave current policy: frequency should be within 400 MHz and 3.50 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 1.54 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 12: Number of idle states: 5 Available idle states: POLL C1E C6 C8 C10 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 23587 Duration: 1272631 C1E: Flags/Description: MWAIT 0x01 Latency: 2 Usage: 1051408 Duration: 255336692 C6: Flags/Description: MWAIT 0x20 Latency: 170 Usage: 219788 Duration: 126246464 C8: Flags/Description: MWAIT 0x40 Latency: 200 Usage: 236692 Duration: 157157274 C10: Flags/Description: MWAIT 0x60 Latency: 230 Usage: 1418643 Duration: 1912917503
