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: 400 MHz - 2.00 GHz available cpufreq governors: performance powersave current policy: frequency should be within 400 MHz and 2.00 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: 632 MHz (asserted by call to hardware) boost state support: Supported: no Active: no 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: 338 Duration: 172953 C1-SKL: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 22285 Duration: 6976617 C1E-SKL: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 29965 Duration: 16852496 C3-SKL: Flags/Description: MWAIT 0x10 Latency: 70 Usage: 7038 Duration: 4399490 C6-SKL: Flags/Description: MWAIT 0x20 Latency: 85 Usage: 36163 Duration: 31110126 C7s-SKL: Flags/Description: MWAIT 0x33 Latency: 124 Usage: 1454 Duration: 2110299 C8-SKL: Flags/Description: MWAIT 0x40 Latency: 200 Usage: 35356 Duration: 108530151 C9-SKL: Flags/Description: MWAIT 0x50 Latency: 480 Usage: 150 Duration: 151836 C10-SKL: Flags/Description: MWAIT 0x60 Latency: 890 Usage: 12374 Duration: 177947515
