frequency-info -------------- analyzing CPU 2: driver: intel_pstate CPUs which run at the same hardware frequency: 2 CPUs which need to have their frequency coordinated by software: 2 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: Unable to call hardware current CPU frequency: 3.90 GHz (asserted by call to kernel) boost state support: Supported: no Active: no idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 0: Number of idle states: 7 Available idle states: POLL C1 C1E C3 C6 C7s C8 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 28189 Duration: 630055 C1: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 324891 Duration: 26369914 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 1436629 Duration: 158328064 C3: Flags/Description: MWAIT 0x10 Latency: 70 Usage: 958808 Duration: 151394425 C6: Flags/Description: MWAIT 0x20 Latency: 85 Usage: 2317078 Duration: 1067100010 C7s: Flags/Description: MWAIT 0x33 Latency: 124 Usage: 2681 Duration: 1962186 C8: Flags/Description: MWAIT 0x40 Latency: 200 Usage: 1104752 Duration: 1243014201
