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: 400 MHz - 3.60 GHz available cpufreq governors: performance powersave current policy: frequency should be within 400 MHz and 3.60 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: 2.73 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 5: Number of idle states: 4 Available idle states: POLL C1E C6 C10 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Residency: 0 Usage: 1169 Duration: 59321 C1E: Flags/Description: MWAIT 0x01 Latency: 1 Residency: 1 Usage: 115756 Duration: 21897701 C6: Flags/Description: MWAIT 0x20 Latency: 140 Residency: 420 Usage: 157375 Duration: 117053586 C10: Flags/Description: MWAIT 0x60 Latency: 310 Residency: 930 Usage: 109584 Duration: 420138618
