frequency-info -------------- analyzing CPU 12: driver: intel_pstate CPUs which run at the same hardware frequency: 12 CPUs which need to have their frequency coordinated by software: 12 maximum transition latency: Cannot determine or is not supported. hardware limits: 400 MHz - 3.80 GHz available cpufreq governors: performance powersave current policy: frequency should be within 400 MHz and 3.80 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 2.00 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 15: Number of idle states: 4 Available idle states: POLL C1E C6 C10 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 8960 Duration: 555184 C1E: Flags/Description: MWAIT 0x01 Latency: 1 Usage: 35798 Duration: 5744413 C6: Flags/Description: MWAIT 0x20 Latency: 140 Usage: 30619 Duration: 21071491 C10: Flags/Description: MWAIT 0x60 Latency: 310 Usage: 86696 Duration: 846565868
