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 - 3.10 GHz available cpufreq governors: conservative ondemand userspace powersave performance schedutil current policy: frequency should be within 800 MHz and 3.10 GHz. The governor "ondemand" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 2.52 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 3: Number of idle states: 6 Available idle states: POLL C1 C1E C3 C6 C7s POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 42240 Duration: 825538 C1: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 24752 Duration: 2309712 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 16987 Duration: 2929644 C3: Flags/Description: MWAIT 0x10 Latency: 33 Usage: 12736 Duration: 2710418 C6: Flags/Description: MWAIT 0x20 Latency: 133 Usage: 3547 Duration: 1168655 C7s: Flags/Description: MWAIT 0x32 Latency: 166 Usage: 125864 Duration: 373663146
