frequency-info -------------- analyzing CPU 3: driver: intel_pstate CPUs which run at the same hardware frequency: 3 CPUs which need to have their frequency coordinated by software: 3 maximum transition latency: Cannot determine or is not supported. hardware limits: 400 MHz - 3.20 GHz available cpufreq governors: performance powersave current policy: frequency should be within 400 MHz and 3.20 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 3.05 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 3: 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: 16888 Duration: 479111 C1: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 169023 Duration: 17338497 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 306863 Duration: 46426104 C3: Flags/Description: MWAIT 0x10 Latency: 70 Usage: 181557 Duration: 25145378 C6: Flags/Description: MWAIT 0x20 Latency: 85 Usage: 697048 Duration: 256268430 C7s: Flags/Description: MWAIT 0x33 Latency: 124 Usage: 6103 Duration: 4286581 C8: Flags/Description: MWAIT 0x40 Latency: 200 Usage: 426882 Duration: 280951296 C9: Flags/Description: MWAIT 0x50 Latency: 480 Usage: 11877 Duration: 17518619 C10: Flags/Description: MWAIT 0x60 Latency: 890 Usage: 358275 Duration: 1278189538
