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: 480 MHz - 2.16 GHz available cpufreq governors: conservative ondemand userspace powersave performance schedutil current policy: frequency should be within 480 MHz and 2.16 GHz. The governor "performance" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 644 MHz (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 C6N C6S C7 C7S POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 5159 Duration: 290742 C1: Flags/Description: MWAIT 0x00 Latency: 1 Usage: 155833 Duration: 31473759 C6N: Flags/Description: MWAIT 0x58 Latency: 80 Usage: 123977 Duration: 56487960 C6S: Flags/Description: MWAIT 0x52 Latency: 200 Usage: 157633 Duration: 120091536 C7: Flags/Description: MWAIT 0x60 Latency: 1200 Usage: 58663 Duration: 218335511 C7S: Flags/Description: MWAIT 0x64 Latency: 10000 Usage: 7179 Duration: 145968467
