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: 3.89 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: 13618 Duration: 5497503 C1-HSW: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 537194 Duration: 466995231 C1E-HSW: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 390661 Duration: 216864601 C3-HSW: Flags/Description: MWAIT 0x10 Latency: 33 Usage: 207855 Duration: 100297783 C6-HSW: Flags/Description: MWAIT 0x20 Latency: 133 Usage: 70010 Duration: 48438905 C7s-HSW: Flags/Description: MWAIT 0x32 Latency: 166 Usage: 1196489 Duration: 3792947597
