frequency-info -------------- analyzing CPU 4: driver: intel_pstate CPUs which run at the same hardware frequency: 4 CPUs which need to have their frequency coordinated by software: 4 energy performance preference: balance_performance hardware limits: 800 MHz - 3.80 GHz available cpufreq governors: performance powersave current policy: frequency should be within 800 MHz and 3.80 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: 3.47 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 3: 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: 1759 Duration: 23927 C1: Flags/Description: MWAIT 0x00 Latency: 2 Residency: 2 Usage: 18430 Duration: 3769716 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Residency: 20 Usage: 12960 Duration: 2144413 C3: Flags/Description: MWAIT 0x10 Latency: 70 Residency: 100 Usage: 6360 Duration: 763471 C6: Flags/Description: MWAIT 0x20 Latency: 85 Residency: 200 Usage: 26645 Duration: 13551989 C7s: Flags/Description: MWAIT 0x33 Latency: 124 Residency: 800 Usage: 0 Duration: 0 C8: Flags/Description: MWAIT 0x40 Latency: 200 Residency: 800 Usage: 8895 Duration: 6764723 C9: Flags/Description: MWAIT 0x50 Latency: 480 Residency: 5000 Usage: 3768 Duration: 1652635 C10: Flags/Description: MWAIT 0x60 Latency: 890 Residency: 5000 Usage: 53072 Duration: 372829195
