frequency-info -------------- analyzing CPU 1: driver: intel_cpufreq CPUs which run at the same hardware frequency: 1 CPUs which need to have their frequency coordinated by software: 1 maximum transition latency: 20.0 us hardware limits: 1.60 GHz - 3.90 GHz available cpufreq governors: conservative ondemand userspace powersave performance schedutil current policy: frequency should be within 1.60 GHz and 3.10 GHz. The governor "performance" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 3.20 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes 3900 MHz max turbo 4 active cores 3900 MHz max turbo 3 active cores 3900 MHz max turbo 2 active cores 3900 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: 813 Duration: 13676 C1: Flags/Description: MWAIT 0x00 Latency: 1 Usage: 7946 Duration: 489321 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 11815 Duration: 1767700 C3: Flags/Description: MWAIT 0x10 Latency: 59 Usage: 3579 Duration: 866614 C6: Flags/Description: MWAIT 0x20 Latency: 80 Usage: 166403 Duration: 413655962
