开启完整HWP(SpeedShift)电源管理特性

641287677

请问如何检测是否完整的开启了HWP所有功能呢？我现在只在Clover中勾选了HWPEnable和UseARTFrequency，以及设置了HWPValue，这样下来用HWMonitor以及Intel Power Gadget检测变频都是有很多档，看起来HWP应该是开启了，另外两个x86也加载了。通过AppleIntelInfo.kext的日志看似乎HWP也是开启了。

麻烦帮我看看是否还需要向楼主这样操作，谢谢。

UseARTFrequency以及HWPValue怎么设置？从没见过此类帖子

我是参考这篇帖子的设置的 Skylake HWP Enable ，从效果上来看还不错，就是不知道有没有楼主所说的完整开启HWP。

641287677

请问是否可以理解为“MSR 0xE2 lock的主板”才需要这么做？

你需要在设置 节能器中查看是否有三到四项电源勾选 没有的话表明HWP并没有完整开启。

你说的是这几项吗？这个貌似在DSDT里面加入LPC的patch就有了。

从Intel Power Gadget上看这变频效果还不错，像是HWP开启了。我之前没有勾选HWPEnable的选项之前只有最低频和最高频。

终于发中文版的了，话说我这个无论频率设成多低，最低频率总在1400左右

你这变频效果可以了啊，8个档。我的Macbook Pro with Touchbar正好是这个型号的MacBookPro13,2 。也是8个档，跟你这差不多。

你这CPU设置机型IMC17,1还比较合适吧，毕竟IMC17,1用过I5-6500

iMac17,1有三种分别是i5 6500，i5 6600和i7 6700K

Pike 的 freqVectorsEdit.sh 是替换其他机型的 FrequencyVectors ，这个脚本的主要目的和 HWP 无关，而是 ...

这个解释很好，终于让我明白了FrequencyVectors
