frequency-info -------------- analyzing CPU 3: driver: intel_cpufreq CPUs which run at the same hardware frequency: 3 CPUs which need to have their frequency coordinated by software: 3 maximum transition latency: 20.0 us hardware limits: 800 MHz - 2.90 GHz available cpufreq governors: conservative ondemand userspace powersave performance schedutil current policy: frequency should be within 800 MHz and 2.90 GHz. The governor "schedutil" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 2.69 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes 2700 MHz max turbo 4 active cores 2700 MHz max turbo 3 active cores 2700 MHz max turbo 2 active cores 2900 MHz max turbo 1 active cores idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 2: Number of idle states: 6 Available idle states: POLL C1 C1E C3 C6 C7 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 23869 Duration: 492672 C1: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 5735 Duration: 451841 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 9582 Duration: 1521366 C3: Flags/Description: MWAIT 0x10 Latency: 80 Usage: 3072 Duration: 896119 C6: Flags/Description: MWAIT 0x20 Latency: 104 Usage: 25 Duration: 11827 C7: Flags/Description: MWAIT 0x30 Latency: 109 Usage: 45788 Duration: 304593471
