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: 800 MHz - 2.80 GHz available cpufreq governors: conservative ondemand userspace powersave performance schedutil current policy: frequency should be within 800 MHz and 2.80 GHz. The governor "ondemand" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 2.66 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: 8 Available idle states: POLL C1 C1E C6 C7s C8 C9 C10 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 82037 Duration: 1284972 C1: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 90044 Duration: 13891228 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 225454 Duration: 39436423 C6: Flags/Description: MWAIT 0x20 Latency: 150 Usage: 0 Duration: 0 C7s: Flags/Description: MWAIT 0x31 Latency: 150 Usage: 221477 Duration: 95403496 C8: Flags/Description: MWAIT 0x40 Latency: 5963 Usage: 7228 Duration: 3133260 C9: Flags/Description: MWAIT 0x50 Latency: 5963 Usage: 5199 Duration: 4374288 C10: Flags/Description: MWAIT 0x60 Latency: 6291 Usage: 73192 Duration: 136184793
