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: 1.60 GHz - 3.20 GHz available cpufreq governors: performance powersave current policy: frequency should be within 1.60 GHz and 3.20 GHz. The governor "performance" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 1.87 GHz (asserted by call to kernel) boost state support: Supported: no Active: no 3400 MHz max turbo 4 active cores 3500 MHz max turbo 3 active cores 3600 MHz max turbo 2 active cores 3600 MHz max turbo 1 active cores idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 0: Number of idle states: 5 Available idle states: POLL C1 C1E C3 C6 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 529 Duration: 21492 C1: Flags/Description: MWAIT 0x00 Latency: 1 Usage: 72324 Duration: 6071601 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 167055 Duration: 28392805 C3: Flags/Description: MWAIT 0x10 Latency: 59 Usage: 33168 Duration: 6695466 C6: Flags/Description: MWAIT 0x20 Latency: 80 Usage: 413030 Duration: 799127829
