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: 1.80 GHz (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: 205 Duration: 269211 C1-SKL: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 13574 Duration: 3761226 C1E-SKL: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 18979 Duration: 11703488 C3-SKL: Flags/Description: MWAIT 0x10 Latency: 70 Usage: 5587 Duration: 4286117 C6-SKL: Flags/Description: MWAIT 0x20 Latency: 85 Usage: 27664 Duration: 22380735 C7s-SKL: Flags/Description: MWAIT 0x33 Latency: 124 Usage: 1061 Duration: 2992111 C8-SKL: Flags/Description: MWAIT 0x40 Latency: 200 Usage: 32874 Duration: 74397208 C9-SKL: Flags/Description: MWAIT 0x50 Latency: 480 Usage: 502 Duration: 3906174 C10-SKL: Flags/Description: MWAIT 0x60 Latency: 890 Usage: 8207 Duration: 92192223
