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 - 3.40 GHz available cpufreq governors: conservative ondemand userspace powersave performance schedutil current policy: frequency should be within 800 MHz and 3.40 GHz. The governor "ondemand" may decide which speed to use within this range. current CPU frequency: 2.79 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 0: Number of idle states: 6 Available idle states: POLL C1 C1E C3 C6 C7s POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Residency: 0 Usage: 2051 Duration: 25865 C1: Flags/Description: MWAIT 0x00 Latency: 2 Residency: 2 Usage: 19125 Duration: 2009585 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Residency: 20 Usage: 24922 Duration: 3289189 C3: Flags/Description: MWAIT 0x10 Latency: 33 Residency: 100 Usage: 36619 Duration: 9389118 C6: Flags/Description: MWAIT 0x20 Latency: 133 Residency: 400 Usage: 11452 Duration: 5382881 C7s: Flags/Description: MWAIT 0x32 Latency: 166 Residency: 500 Usage: 170947 Duration: 347683687
