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 energy performance preference: balance_performance hardware limits: 400 MHz - 3.40 GHz available cpufreq governors: performance powersave current policy: frequency should be within 400 MHz and 3.40 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: 3.10 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: 2786 Duration: 47579 C1: Flags/Description: MWAIT 0x00 Latency: 2 Residency: 2 Usage: 20378 Duration: 2493607 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Residency: 20 Usage: 40520 Duration: 6637865 C3: Flags/Description: MWAIT 0x10 Latency: 70 Residency: 100 Usage: 30371 Duration: 7543927 C6: Flags/Description: MWAIT 0x20 Latency: 85 Residency: 200 Usage: 96704 Duration: 48500399 C7s: Flags/Description: MWAIT 0x33 Latency: 124 Residency: 800 Usage: 0 Duration: 0 C8: Flags/Description: MWAIT 0x40 Latency: 200 Residency: 800 Usage: 39556 Duration: 28200962 C9: Flags/Description: MWAIT 0x50 Latency: 480 Residency: 5000 Usage: 1669 Duration: 3973867 C10: Flags/Description: MWAIT 0x60 Latency: 890 Residency: 5000 Usage: 40232 Duration: 278251732
