我正在使用带有省电调节器的 TLP 和启用了 Intel Sidestep 的 intel_pstate 驱动程序。
我注意到省电调节器发挥了作用，内核在空闲时处于 800Mhz 的频率，但是当引入任何类型的负载时，所有内核的时钟频率都会上升。无论负载如何，它们在所有意图和目的上都保持大致相同的时钟速度。我启动了一个单线程工作负载，甚至尝试将其内核亲和性限制为内核 0，但它们都达到了 1.5GHZ 的最大值。
我的理解是，它应该能够只为需要节省电量的内核提供时钟频率？我错了吗？
还值得一提的是，我无法使用 cpupower 设置每个核心的频率（它总是影响所有核心）
它应该像我想象的那样运行吗？如果是这样，那有什么问题？
