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 - 1.92 GHz available cpufreq governors: conservative ondemand userspace powersave performance schedutil current policy: frequency should be within 480 MHz and 1.92 GHz. The governor "performance" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 1.57 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 C6N C6S C7 C7S POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 7886 Duration: 1400485 C1: Flags/Description: MWAIT 0x00 Latency: 1 Usage: 128540 Duration: 17820490 C6N: Flags/Description: MWAIT 0x58 Latency: 80 Usage: 25061 Duration: 13700548 C6S: Flags/Description: MWAIT 0x52 Latency: 200 Usage: 181614 Duration: 353096772 C7: Flags/Description: MWAIT 0x60 Latency: 1200 Usage: 132870 Duration: 454900882 C7S: Flags/Description: MWAIT 0x64 Latency: 10000 Usage: 18653 Duration: 183639770
