frequency-info -------------- analyzing CPU 19: driver: intel_cpufreq CPUs which run at the same hardware frequency: 19 CPUs which need to have their frequency coordinated by software: 19 maximum transition latency: 20.0 us hardware limits: 1.20 GHz - 2.50 GHz available cpufreq governors: conservative ondemand userspace powersave performance schedutil current policy: frequency should be within 1.20 GHz and 2.50 GHz. The governor "schedutil" may decide which speed to use within this range. current CPU frequency: 1.90 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes 2400 MHz max turbo 4 active cores 2400 MHz max turbo 3 active cores 2500 MHz max turbo 2 active cores 2500 MHz max turbo 1 active cores idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 21: Number of idle states: 6 Available idle states: POLL C1 C1E C3 C6 C7 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Residency: 0 Usage: 619 Duration: 11316 C1: Flags/Description: MWAIT 0x00 Latency: 2 Residency: 2 Usage: 11695 Duration: 685699 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Residency: 20 Usage: 61195 Duration: 13470241 C3: Flags/Description: MWAIT 0x10 Latency: 80 Residency: 211 Usage: 26695 Duration: 10209294 C6: Flags/Description: MWAIT 0x20 Latency: 104 Residency: 345 Usage: 0 Duration: 0 C7: Flags/Description: MWAIT 0x30 Latency: 109 Residency: 345 Usage: 389129 Duration: 3415856549
