frequency-info -------------- analyzing CPU 0: driver: intel_pstate CPUs which run at the same hardware frequency: 0 CPUs which need to have their frequency coordinated by software: 0 maximum transition latency: Cannot determine or is not supported. hardware limits: 800 MHz - 3.20 GHz available cpufreq governors: performance powersave current policy: frequency should be within 800 MHz and 3.20 GHz. The governor "performance" may decide which speed to use within this range. current CPU frequency: 2.51 GHz (asserted by call to hardware) boost state support: Supported: yes Active: yes idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 0: Number of idle states: 4 Available idle states: POLL C1-SKX C1E-SKX C6-SKX POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 9439 Duration: 665024 C1-SKX: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 2665102 Duration: 4951587660 C1E-SKX: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 5596806 Duration: 5414703406 C6-SKX: Flags/Description: MWAIT 0x20 Latency: 133 Usage: 8591541 Duration: 63090816551
