frequency-info -------------- analyzing CPU 0: driver: intel_cpufreq CPUs which run at the same hardware frequency: 0 CPUs which need to have their frequency coordinated by software: 0 maximum transition latency: 20.0 us hardware limits: 500 MHz - 2.70 GHz available cpufreq governors: conservative ondemand userspace powersave performance schedutil current policy: frequency should be within 500 MHz and 2.70 GHz. The governor "schedutil" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 2.20 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 Usage: 1256781 Duration: 6471805 C1: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 9900045 Duration: 726303213 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 11732303 Duration: 1238268231 C3: Flags/Description: MWAIT 0x10 Latency: 40 Usage: 19549068 Duration: 4967958924 C6: Flags/Description: MWAIT 0x20 Latency: 133 Usage: 4954367 Duration: 2234569831 C7s: Flags/Description: MWAIT 0x32 Latency: 166 Usage: 12378661 Duration: 7414315029 C8: Flags/Description: MWAIT 0x40 Latency: 300 Usage: 3933916 Duration: 2697455523 C9: Flags/Description: MWAIT 0x50 Latency: 600 Usage: 10804420 Duration: 22800740694 C10: Flags/Description: MWAIT 0x60 Latency: 2600 Usage: 891613 Duration: 8639196255
