frequency-info -------------- analyzing CPU 4: driver: intel_cpufreq CPUs which run at the same hardware frequency: 4 CPUs which need to have their frequency coordinated by software: 4 maximum transition latency: 20.0 us hardware limits: 1.20 GHz - 3.80 GHz available cpufreq governors: conservative ondemand userspace powersave performance schedutil current policy: frequency should be within 1.20 GHz and 3.80 GHz. The governor "ondemand" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 3.49 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes 3600 MHz max turbo 4 active cores 3600 MHz max turbo 3 active cores 3700 MHz max turbo 2 active cores 3800 MHz max turbo 1 active cores idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 5: Number of idle states: 5 Available idle states: POLL C1 C1E C3 C6 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 66096 Duration: 362164 C1: Flags/Description: MWAIT 0x00 Latency: 1 Usage: 31035 Duration: 2681020 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 1095 Duration: 342499 C3: Flags/Description: MWAIT 0x10 Latency: 59 Usage: 838 Duration: 275423 C6: Flags/Description: MWAIT 0x20 Latency: 82 Usage: 27467 Duration: 430064728
