frequency-info -------------- analyzing CPU 27: driver: intel_cpufreq CPUs which run at the same hardware frequency: 27 CPUs which need to have their frequency coordinated by software: 27 maximum transition latency: 20.0 us hardware limits: 1.20 GHz - 3.60 GHz available cpufreq governors: performance schedutil current policy: frequency should be within 1.20 GHz and 3.60 GHz. The governor "schedutil" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 3.21 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 9: Number of idle states: 5 Available idle states: POLL C1 C1E C3 C6 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 15798 Duration: 156030 C1: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 43110 Duration: 18312222 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 1746339 Duration: 7580087488 C3 (DISABLED) : Flags/Description: MWAIT 0x10 Latency: 40 Usage: 0 Duration: 0 C6 (DISABLED) : Flags/Description: MWAIT 0x20 Latency: 133 Usage: 0 Duration: 0
