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 - 3.60 GHz available cpufreq governors: ondemand performance schedutil current policy: frequency should be within 800 MHz and 3.60 GHz. The governor "ondemand" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 3.48 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: 7 Available idle states: POLL C1 C1E C3 C6 C7s C8 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 453908 Duration: 2763097 C1: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 3286184 Duration: 681991620 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 4350342 Duration: 2175349239 C3: Flags/Description: MWAIT 0x10 Latency: 70 Usage: 1544 Duration: 1567330 C6: Flags/Description: MWAIT 0x20 Latency: 85 Usage: 1992491 Duration: 2436956364 C7s: Flags/Description: MWAIT 0x33 Latency: 124 Usage: 77354 Duration: 158223001 C8: Flags/Description: MWAIT 0x40 Latency: 200 Usage: 730662 Duration: 2593471337
