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: 800 MHz (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: 7 Available idle states: POLL C1-SKL C1E-SKL C3-SKL C6-SKL C7s-SKL C8-SKL POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 2357 Duration: 905472 C1-SKL: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 142730 Duration: 14151518 C1E-SKL: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 146279 Duration: 52536036 C3-SKL: Flags/Description: MWAIT 0x10 Latency: 70 Usage: 54145 Duration: 16814185 C6-SKL: Flags/Description: MWAIT 0x20 Latency: 85 Usage: 246431 Duration: 175697929 C7s-SKL: Flags/Description: MWAIT 0x33 Latency: 124 Usage: 3114 Duration: 7819975 C8-SKL: Flags/Description: MWAIT 0x40 Latency: 200 Usage: 221820 Duration: 883040677
