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 energy performance preference: balance_performance hardware limits: 800 MHz - 4.60 GHz available cpufreq governors: performance powersave current policy: frequency should be within 800 MHz and 4.60 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: 4.40 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 Residency: 0 Usage: 1584 Duration: 20213 C1: Flags/Description: MWAIT 0x00 Latency: 2 Residency: 2 Usage: 41516 Duration: 2641942 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Residency: 20 Usage: 136606 Duration: 8205904 C3: Flags/Description: MWAIT 0x10 Latency: 70 Residency: 100 Usage: 18068 Duration: 2048846 C6: Flags/Description: MWAIT 0x20 Latency: 85 Residency: 200 Usage: 50369 Duration: 20619063 C7s: Flags/Description: MWAIT 0x33 Latency: 124 Residency: 800 Usage: 0 Duration: 0 C8: Flags/Description: MWAIT 0x40 Latency: 200 Residency: 800 Usage: 28366 Duration: 20117926 C9: Flags/Description: MWAIT 0x50 Latency: 480 Residency: 5000 Usage: 1951 Duration: 2740336 C10: Flags/Description: MWAIT 0x60 Latency: 890 Residency: 5000 Usage: 83364 Duration: 325971929
