frequency-info -------------- analyzing CPU 2: driver: intel_cpufreq CPUs which run at the same hardware frequency: 2 CPUs which need to have their frequency coordinated by software: 2 maximum transition latency: 20.0 us hardware limits: 480 MHz - 2.40 GHz available cpufreq governors: conservative ondemand userspace powersave performance schedutil current policy: frequency should be within 480 MHz and 2.40 GHz. The governor "schedutil" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 2.07 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 2: Number of idle states: 6 Available idle states: POLL C1 C6N C6S C7 C7S POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 1202 Duration: 63984 C1: Flags/Description: MWAIT 0x00 Latency: 1 Usage: 25349 Duration: 5490500 C6N: Flags/Description: MWAIT 0x58 Latency: 80 Usage: 12765 Duration: 6983554 C6S: Flags/Description: MWAIT 0x52 Latency: 200 Usage: 27889 Duration: 26796383 C7: Flags/Description: MWAIT 0x60 Latency: 1200 Usage: 28165 Duration: 63503425 C7S: Flags/Description: MWAIT 0x64 Latency: 10000 Usage: 3799 Duration: 29421984
