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 - 3.90 GHz available cpufreq governors: performance powersave current policy: frequency should be within 800 MHz and 3.90 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: 3.86 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: 6 Available idle states: POLL C1-HSW C1E-HSW C3-HSW C6-HSW C7s-HSW POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 2124 Duration: 1180928 C1-HSW: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 615965 Duration: 492234801 C1E-HSW: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 590851 Duration: 442875562 C3-HSW: Flags/Description: MWAIT 0x10 Latency: 33 Usage: 216508 Duration: 112552563 C6-HSW: Flags/Description: MWAIT 0x20 Latency: 133 Usage: 69027 Duration: 54628128 C7s-HSW: Flags/Description: MWAIT 0x32 Latency: 166 Usage: 1703945 Duration: 8939878706
