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 - 3.90 GHz available cpufreq governors: performance powersave current policy: frequency should be within 400 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: 2.15 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 0: Number of idle states: 9 Available idle states: POLL C1 C1E C3 C6 C7s C8 C9 C10 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 2642 Duration: 31271 C1: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 8617 Duration: 863534 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 7398 Duration: 1269993 C3: Flags/Description: MWAIT 0x10 Latency: 70 Usage: 5251 Duration: 1157502 C6: Flags/Description: MWAIT 0x20 Latency: 85 Usage: 23365 Duration: 12931803 C7s: Flags/Description: MWAIT 0x33 Latency: 124 Usage: 24 Duration: 24332 C8: Flags/Description: MWAIT 0x40 Latency: 200 Usage: 28951 Duration: 40669948 C9: Flags/Description: MWAIT 0x50 Latency: 480 Usage: 339 Duration: 825765 C10: Flags/Description: MWAIT 0x60 Latency: 890 Usage: 14733 Duration: 315606969
