frequency-info -------------- analyzing CPU 1: driver: intel_pstate CPUs which run at the same hardware frequency: 1 CPUs which need to have their frequency coordinated by software: 1 energy performance preference: performance hardware limits: 400 MHz - 4.20 GHz available cpufreq governors: performance powersave current policy: frequency should be within 400 MHz and 4.20 GHz. The governor "performance" may decide which speed to use within this range. current CPU frequency: 4.08 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 1: 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 Residency: 0 Usage: 23715 Duration: 544870 C1: Flags/Description: MWAIT 0x00 Latency: 2 Residency: 2 Usage: 8238964 Duration: 606153577 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Residency: 20 Usage: 559381 Duration: 82065877 C3: Flags/Description: MWAIT 0x10 Latency: 70 Residency: 100 Usage: 448178 Duration: 63145971 C6: Flags/Description: MWAIT 0x20 Latency: 85 Residency: 200 Usage: 1748979 Duration: 766380475 C7s: Flags/Description: MWAIT 0x33 Latency: 124 Residency: 800 Usage: 0 Duration: 0 C8: Flags/Description: MWAIT 0x40 Latency: 200 Residency: 800 Usage: 1014416 Duration: 717387565 C9: Flags/Description: MWAIT 0x50 Latency: 480 Residency: 5000 Usage: 313697 Duration: 58969199 C10: Flags/Description: MWAIT 0x60 Latency: 890 Residency: 5000 Usage: 8015672 Duration: 9089447462
