frequency-info -------------- analyzing CPU 6: driver: intel_cpufreq CPUs which run at the same hardware frequency: 6 CPUs which need to have their frequency coordinated by software: 6 maximum transition latency: 20.0 us hardware limits: 800 MHz - 3.50 GHz available cpufreq governors: performance schedutil current policy: frequency should be within 800 MHz and 3.50 GHz. The governor "schedutil" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 2.27 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 C1E C3 C6 C7s POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 4177 Duration: 22995 C1: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 14380 Duration: 860085 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 11332 Duration: 1316205 C3: Flags/Description: MWAIT 0x10 Latency: 33 Usage: 13284 Duration: 3382397 C6: Flags/Description: MWAIT 0x20 Latency: 133 Usage: 3967 Duration: 1579937 C7s: Flags/Description: MWAIT 0x32 Latency: 166 Usage: 76120 Duration: 288551549
