摘要： 在推出英特尔Alder Lake处理器的过去一年里，英特尔工程师已经对Linux内核进行了一些改进，以便更好地处理混合P核与E核的混合处理运算方法。虽然Alder Lake在最近版本的内核中运行得很好，而且Linux上的P核与E核的任务选择比推出时要更完善，但仍有英特尔工程师本周提出了其中需要改进的地方。 上周有重要的Linux内核补丁系列发布，致力于混合CPU的”任务类”和正确实现Linux上的线程管理支持。本周，在Linux管道工会议上（Linux Plumbers Conference）还提出了如何将Linux的能源意识调度适应于 英特尔 混合CPU的议题，因为现在EAS只是为Arm big.LITTLE设计量身定做。 在本周的LPC2022会议上，英特尔工程师Zhang Rui和Chen Yu提到了英特尔混合Linux的工作仍然需要完善。这次额外的发言是提出Linux内核的负载平衡机制对于英特尔的混合处理器来说依然不尽如人意。 特别是，用于计算频率刻度的频率最大值是一个全局值，而不是针对不同类型的核心，因为P核和E核在操作过程中有着不同的最大频率值。频率最大值也可以根据睿频模式、热\/功率节流等而无法被正确判断，并且最大频率值也不能在运行时调整。 对这个话题感兴趣的人可以在下面的地址中找到完整的幻灯片，其中概述了目前英特尔混合CPU的Linux负载平衡问题以及可能的改进。 https:\/\/lpc.events\/event\/16\/contributions\/1191\/attachments\/1074\/2125\/LPC-2022-1-freq.pdf<\/a>
