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: 700 MHz - 3.40 GHz available cpufreq governors: performance powersave current policy: frequency should be within 700 MHz and 3.40 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 3.12 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: 5 Available idle states: POLL C1E C6 C8 C10 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 2310 Duration: 102100 C1E: Flags/Description: MWAIT 0x01 Latency: 2 Usage: 37287 Duration: 6765417 C6: Flags/Description: MWAIT 0x20 Latency: 195 Usage: 15818 Duration: 13641925 C8: Flags/Description: MWAIT 0x40 Latency: 260 Usage: 4436 Duration: 6725739 C10: Flags/Description: MWAIT 0x60 Latency: 660 Usage: 29233 Duration: 660879577
