Linux 中的 powercfg.exe

Question

有人可以翻译这些Linux命令吗？

powercfg.exe /setACvalueindex OVERLAY_SCHEME_MAX SUB_PROCESSOR PERFEPP 0
powercfg.exe /setACvalueindex SCHEME_BALANCED SUB_PROCESSOR PERFEPP 33
powercfg.exe /setACvalueindex OVERLAY_SCHEME_MIN SUB_PROCESSOR PERFEPP 60 

我在 Lenovo X1 Carbon 6th 上遇到 CPU 问题（插入交流电源）始终固定在 4Ghz 上，使风扇不断旋转（空闲时），联想论坛中唯一的解决方案是 Windows 命令。

不是这个问题的主题，但我尝试使用以下程序控制 CPU 和 FAN：

• intel-undervolt（将 CPU 缓存设置为 -100 mV）
• 思凡

还：

$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
powersave

以及空闲状态下的 CPU 值：

Cpu speed from cpuinfo 2111.00Mhz
cpuinfo might be wrong if cpufreq is enabled. To guess correctly try estimating via tsc
Linux's inbuilt cpu_khz code emulated now
True Frequency (without accounting Turbo) 2111 MHz
  CPU Multiplier 21x || Bus clock frequency (BCLK) 100.52 MHz

Socket [0] - [physical cores=4, logical cores=8, max online cores ever=4]
  TURBO ENABLED on 4 Cores, Hyper Threading ON
  Max Frequency without considering Turbo 2211.52 MHz (100.52 x [22])
  Max TURBO Multiplier (if Enabled) with 1/2/3/4 Cores is  42x/42x/39x/39x
  Real Current Frequency 3888.34 MHz [100.52 x 38.68] (Max of below)
        Core [core-id]  :Actual Freq (Mult.)      C0%   Halt(C1)%  C3 %   C6 %  Temp      VCore
        Core 1 [0]:       3876.97 (38.57x)      1.02    94.4       1    2.77    57      1.1874
        Core 2 [1]:       3873.57 (38.53x)         1    92.5       1    4.71    58      1.2014
        Core 3 [2]:       3879.58 (38.59x)      1.93    85.7       1    9.77    59      1.2114
        Core 4 [3]:       3888.34 (38.68x)      99.9       0       0       0    78      1.1807

C0 = Processor running without halting
C1 = Processor running with halts (States >C0 are power saver modes with cores idling)
C3 = Cores running with PLL turned off and core cache turned off
C6, C7 = Everything in C3 + core state saved to last level cache, C7 is deeper than C6

谢谢。
