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: 1.60 GHz - 4.10 GHz available cpufreq governors: performance powersave current policy: frequency should be within 1.60 GHz 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: 1.87 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes 4100 MHz max turbo 4 active cores 4100 MHz max turbo 3 active cores 4100 MHz max turbo 2 active cores 4100 MHz max turbo 1 active cores idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 0: Number of idle states: 5 Available idle states: POLL C1 C1E C3 C6 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 42382 Duration: 114650 C1: Flags/Description: MWAIT 0x00 Latency: 1 Usage: 1275953 Duration: 345065510 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 1139063 Duration: 289596853 C3: Flags/Description: MWAIT 0x10 Latency: 59 Usage: 613376 Duration: 162189397 C6: Flags/Description: MWAIT 0x20 Latency: 80 Usage: 7417163 Duration: 10664866819
