frequency-info -------------- analyzing CPU 0: driver: intel_pstate CPUs which run at the same hardware frequency: 0 CPUs which need to have their frequency coordinated by software: 0 maximum transition latency: Cannot determine or is not supported. hardware limits: 400 MHz - 4.90 GHz available cpufreq governors: performance powersave current policy: frequency should be within 400 MHz and 4.90 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 800 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: 9 Available idle states: POLL C1 C1E C3 C6 C7s C8 C9 C10 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 955869 Duration: 900263 C1: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 189934 Duration: 29429667 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 169724 Duration: 49445696 C3: Flags/Description: MWAIT 0x10 Latency: 70 Usage: 107898 Duration: 19480842 C6: Flags/Description: MWAIT 0x20 Latency: 85 Usage: 449940 Duration: 223510800 C7s: Flags/Description: MWAIT 0x33 Latency: 124 Usage: 7508 Duration: 13346310 C8: Flags/Description: MWAIT 0x40 Latency: 200 Usage: 1046130 Duration: 1633304984 C9: Flags/Description: MWAIT 0x50 Latency: 480 Usage: 7988 Duration: 35115208 C10: Flags/Description: MWAIT 0x60 Latency: 890 Usage: 512270 Duration: 3621750589
