frequency-info -------------- analyzing CPU 0: driver: intel_pstate CPUs which run at the same hardware frequency: 0 CPUs which need to have their frequency coordinated by software: 0 maximum transition latency: Cannot determine or is not supported. hardware limits: 800 MHz - 4.10 GHz available cpufreq governors: performance powersave current policy: frequency should be within 800 MHz and 4.10 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: 3.20 GHz (asserted by call to hardware) 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-SKL C1E-SKL C3-SKL C6-SKL C7s-SKL C8-SKL C9-SKL C10-SKL POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 146 Duration: 32733 C1-SKL: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 8572 Duration: 1843594 C1E-SKL: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 8355 Duration: 5868329 C3-SKL: Flags/Description: MWAIT 0x10 Latency: 70 Usage: 3248 Duration: 10759902 C6-SKL: Flags/Description: MWAIT 0x20 Latency: 85 Usage: 17736 Duration: 16180120 C7s-SKL: Flags/Description: MWAIT 0x33 Latency: 124 Usage: 393 Duration: 559001 C8-SKL: Flags/Description: MWAIT 0x40 Latency: 200 Usage: 26637 Duration: 73267309 C9-SKL: Flags/Description: MWAIT 0x50 Latency: 480 Usage: 262 Duration: 1421766 C10-SKL: Flags/Description: MWAIT 0x60 Latency: 890 Usage: 27843 Duration: 1327316129
