frequency-info -------------- analyzing CPU 7: driver: intel_pstate CPUs which run at the same hardware frequency: 7 CPUs which need to have their frequency coordinated by software: 7 maximum transition latency: Cannot determine or is not supported. hardware limits: 400 MHz - 4.60 GHz available cpufreq governors: performance powersave current policy: frequency should be within 400 MHz and 4.60 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 900 MHz (asserted by call to kernel) boost state support: Supported: yes Active: yes idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 7: 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: 1997080 Duration: 79321299 C1: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 776854 Duration: 49291049 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 7638498 Duration: 941340295 C3: Flags/Description: MWAIT 0x10 Latency: 70 Usage: 2450762 Duration: 276806883 C6: Flags/Description: MWAIT 0x20 Latency: 85 Usage: 10446044 Duration: 5121485514 C7s: Flags/Description: MWAIT 0x33 Latency: 124 Usage: 13437 Duration: 7870775 C8: Flags/Description: MWAIT 0x40 Latency: 200 Usage: 7674014 Duration: 5948160176 C9: Flags/Description: MWAIT 0x50 Latency: 480 Usage: 186227 Duration: 527708476 C10: Flags/Description: MWAIT 0x60 Latency: 890 Usage: 12364852 Duration: 113351716232
