intel_pstate 驱动程序让我发疯

Question

我的 intel_pstate 驱动程序有一些问题。

问题 1) 我无法禁用 Turbo。它在 BIOS 中被禁用并通过以下方式：

root@think:~# cat /sys/devices/system/cpu/intel_pstate/no_turbo 
1

问题2）我无法限制最大频率。 “max_perf_pct”设置为33，“min_perf_pct”相同。 CPU 完全忽略所有设置：

Socket [0] - [physical cores=2, logical cores=4, max online cores ever=2]
TURBO DISABLED on 2 Cores, Hyper Threading ON
Max Frequency without considering Turbo 2893.00 MHz (99.76 x [29])
Max TURBO Multiplier (if Enabled) with 1/2/3/4 Cores is  36x/34x/34x/34x
Real Current Frequency 3227.37 MHz [99.76 x 32.35] (Max of below)
      Core [core-id]  :Actual Freq (Mult.)      C0%   Halt(C1)%  C3 %   C6 %
    Core 1 [0]:       3227.37 (32.35x)      44.4    39.2       0       1
    Core 2 [2]:       3189.89 (31.98x)      43.3    44.3       1       1

“2 个核心上禁用 TURBO”...我不这么认为？

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: 0.97 ms.
hardware limits: 1.20 GHz - 3.60 GHz
available cpufreq governors: performance, powersave
current policy: frequency should be within 1.20 GHz and 3.60 GHz.
              The governor "powersave" may decide which speed to use
              within this range.
current CPU frequency is 1.20 GHz (asserted by call to hardware).

谢谢
