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 maximum transition latency: Cannot determine or is not supported. hardware limits: 800 MHz - 4.40 GHz available cpufreq governors: performance powersave current policy: frequency should be within 800 MHz and 4.40 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 890 MHz (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: 5 Available idle states: POLL C1E C6 C8 C10 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 173367 Duration: 707225 C1E: Flags/Description: MWAIT 0x01 Latency: 2 Usage: 58739 Duration: 15167699 C6: Flags/Description: MWAIT 0x20 Latency: 220 Usage: 29254 Duration: 24482296 C8: Flags/Description: MWAIT 0x40 Latency: 280 Usage: 9092 Duration: 6906308 C10: Flags/Description: MWAIT 0x60 Latency: 680 Usage: 56320 Duration: 137718522
