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: 400 MHz - 3.90 GHz available cpufreq governors: performance powersave current policy: frequency should be within 400 MHz and 3.90 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 1.55 GHz (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: 458985 Duration: 7800031 C1: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 3903441 Duration: 310476480 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 10307351 Duration: 1435882351 C3: Flags/Description: MWAIT 0x10 Latency: 70 Usage: 8560962 Duration: 1160048216 C6: Flags/Description: MWAIT 0x20 Latency: 85 Usage: 32842204 Duration: 15006355269 C7s: Flags/Description: MWAIT 0x33 Latency: 124 Usage: 178217 Duration: 211933939 C8: Flags/Description: MWAIT 0x40 Latency: 200 Usage: 18407208 Duration: 13480936354 C9: Flags/Description: MWAIT 0x50 Latency: 480 Usage: 522145 Duration: 902274113 C10: Flags/Description: MWAIT 0x60 Latency: 890 Usage: 8338170 Duration: 37806133872
