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 - 2.58 GHz available cpufreq governors: conservative ondemand userspace powersave performance schedutil current policy: frequency should be within 500 MHz and 2.58 GHz. The governor "ondemand" may decide which speed to use within this range. current CPU frequency: 2.52 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 Residency: 0 Usage: 659 Duration: 21609 C1: Flags/Description: MWAIT 0x00 Latency: 1 Residency: 1 Usage: 44310 Duration: 5838996 C6N: Flags/Description: MWAIT 0x58 Latency: 300 Residency: 275 Usage: 28820 Duration: 13447674 C6S: Flags/Description: MWAIT 0x52 Latency: 500 Residency: 560 Usage: 34952 Duration: 21651835 C7: Flags/Description: MWAIT 0x60 Latency: 1200 Residency: 4000 Usage: 45153 Duration: 158462367 C7S: Flags/Description: MWAIT 0x64 Latency: 10000 Residency: 20000 Usage: 6190 Duration: 94576170
