frequency-info -------------- analyzing CPU 2: driver: intel_cpufreq CPUs which run at the same hardware frequency: 2 CPUs which need to have their frequency coordinated by software: 2 maximum transition latency: 20.0 us hardware limits: 800 MHz - 3.90 GHz available cpufreq governors: ondemand performance schedutil current policy: frequency should be within 800 MHz 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: 3.97 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 4: Number of idle states: 6 Available idle states: POLL C1 C1E C3 C6 C7s POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 5425658 Duration: 21234482 C1: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 2216436 Duration: 294807207 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 5639887 Duration: 650996607 C3: Flags/Description: MWAIT 0x10 Latency: 33 Usage: 2748201 Duration: 782917359 C6: Flags/Description: MWAIT 0x20 Latency: 133 Usage: 556960 Duration: 301788147 C7s: Flags/Description: MWAIT 0x32 Latency: 166 Usage: 15625317 Duration: 117124538607
