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 - 4.30 GHz available cpufreq governors: performance powersave current policy: frequency should be within 800 MHz and 4.30 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 4.09 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 2: 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 Usage: 68658 Duration: 1393859 C1: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 10052 Duration: 629234 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 9209 Duration: 1362032 C3: Flags/Description: MWAIT 0x10 Latency: 70 Usage: 6533 Duration: 888925 C6: Flags/Description: MWAIT 0x20 Latency: 85 Usage: 40189 Duration: 24745502 C7s: Flags/Description: MWAIT 0x33 Latency: 124 Usage: 65 Duration: 98442 C8: Flags/Description: MWAIT 0x40 Latency: 200 Usage: 12627 Duration: 10196800 C9: Flags/Description: MWAIT 0x50 Latency: 480 Usage: 424 Duration: 1106012 C10: Flags/Description: MWAIT 0x60 Latency: 890 Usage: 25037 Duration: 381948161
