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: 500 MHz - 2.90 GHz available cpufreq governors: conservative ondemand userspace powersave performance schedutil current policy: frequency should be within 500 MHz and 2.90 GHz. The governor "schedutil" may decide which speed to use within this range. current CPU frequency: 2.29 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: 9 Available idle states: POLL C1 C1E C3 C6 C7s C8 C9 C10 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Residency: 0 Usage: 15596 Duration: 155666 C1: Flags/Description: MWAIT 0x00 Latency: 2 Residency: 2 Usage: 221929 Duration: 18691059 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Residency: 20 Usage: 194643 Duration: 22766685 C3: Flags/Description: MWAIT 0x10 Latency: 40 Residency: 100 Usage: 419262 Duration: 134813701 C6: Flags/Description: MWAIT 0x20 Latency: 133 Residency: 400 Usage: 103356 Duration: 54392587 C7s: Flags/Description: MWAIT 0x32 Latency: 166 Residency: 500 Usage: 203989 Duration: 124642366 C8: Flags/Description: MWAIT 0x40 Latency: 300 Residency: 900 Usage: 69093 Duration: 49782862 C9: Flags/Description: MWAIT 0x50 Latency: 600 Residency: 1800 Usage: 206220 Duration: 369685084 C10: Flags/Description: MWAIT 0x60 Latency: 2600 Residency: 7700 Usage: 36689 Duration: 66522568
