frequency-info -------------- analyzing CPU 2: driver: intel_pstate CPUs which run at the same hardware frequency: 2 CPUs which need to have their frequency coordinated by software: 2 maximum transition latency: Cannot determine or is not supported. hardware limits: 700 MHz - 3.60 GHz available cpufreq governors: performance powersave current policy: frequency should be within 700 MHz and 3.60 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 2.63 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 2: Number of idle states: 5 Available idle states: POLL C1E C6 C8 C10 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 4234 Duration: 132515 C1E: Flags/Description: MWAIT 0x01 Latency: 2 Usage: 61738 Duration: 18531059 C6: Flags/Description: MWAIT 0x20 Latency: 195 Usage: 22509 Duration: 17995949 C8: Flags/Description: MWAIT 0x40 Latency: 260 Usage: 19786 Duration: 30947019 C10: Flags/Description: MWAIT 0x60 Latency: 660 Usage: 76861 Duration: 1634898263
