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: 1.20 GHz - 3.90 GHz available cpufreq governors: performance powersave current policy: frequency should be within 1.20 GHz and 3.90 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: 3.40 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 4: Number of idle states: 4 Available idle states: POLL C1 C1E C6 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Residency: 0 Usage: 721043 Duration: 1665656 C1: Flags/Description: MWAIT 0x00 Latency: 2 Residency: 2 Usage: 269927 Duration: 7963195 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Residency: 20 Usage: 102703 Duration: 21622514 C6: Flags/Description: MWAIT 0x20 Latency: 133 Residency: 600 Usage: 99411 Duration: 347694238
