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 - 4.10 GHz available cpufreq governors: performance powersave current policy: frequency should be within 400 MHz and 4.10 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 2.55 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 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: 9882 Duration: 258539 C1: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 224405 Duration: 17022773 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 224289 Duration: 26218471 C3: Flags/Description: MWAIT 0x10 Latency: 70 Usage: 113513 Duration: 12134893 C6: Flags/Description: MWAIT 0x20 Latency: 85 Usage: 799270 Duration: 590396339 C7s: Flags/Description: MWAIT 0x33 Latency: 124 Usage: 578 Duration: 386508 C8: Flags/Description: MWAIT 0x40 Latency: 200 Usage: 458417 Duration: 449849434 C9: Flags/Description: MWAIT 0x50 Latency: 480 Usage: 38991 Duration: 25283880 C10: Flags/Description: MWAIT 0x60 Latency: 890 Usage: 2880708 Duration: 21267365563
