frequency-info -------------- analyzing CPU 5: driver: intel_cpufreq CPUs which run at the same hardware frequency: 5 CPUs which need to have their frequency coordinated by software: 5 maximum transition latency: 20.0 us hardware limits: 1.60 GHz - 3.90 GHz available cpufreq governors: performance schedutil current policy: frequency should be within 1.60 GHz and 3.90 GHz. The governor "schedutil" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 3.60 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes 3600 MHz max turbo 4 active cores 3700 MHz max turbo 3 active cores 3800 MHz max turbo 2 active cores 3900 MHz max turbo 1 active cores idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 3: Number of idle states: 5 Available idle states: POLL C1 C1E C3 C6 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 1009 Duration: 16713 C1: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 7298 Duration: 864399 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 18947 Duration: 2575714 C3: Flags/Description: MWAIT 0x10 Latency: 80 Usage: 2590 Duration: 837076 C6: Flags/Description: MWAIT 0x20 Latency: 104 Usage: 65136 Duration: 938887959
