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 - 3.30 GHz available cpufreq governors: conservative ondemand userspace powersave performance schedutil current policy: frequency should be within 800 MHz and 3.30 GHz. The governor "performance" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 3.19 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 Usage: 42647 Duration: 873436 C1: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 6855 Duration: 577415 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 8947 Duration: 1526158 C3: Flags/Description: MWAIT 0x10 Latency: 33 Usage: 9350 Duration: 2787168 C6: Flags/Description: MWAIT 0x20 Latency: 133 Usage: 2250 Duration: 1112201 C7s: Flags/Description: MWAIT 0x32 Latency: 166 Usage: 46005 Duration: 213065042
