### ? Linux 内核 6.6：都有哪些新元素？


在我们开始之前，需要提醒大家，这一次发布的是**非长期支持版本**，因此不是每个人都必须进行升级，除非你想要享受最新、最棒的版本。


总的来说，让我们来看看这次发布版本的亮点：


* 针对英特尔芯片的优化
* 对笔记本的更佳支持
* 网络改进
* AMD 芯片性能提升


#### 针对英特尔芯片的优化


![](/data/attachment/album/202310/31/204634alrzd80mebeztnnp.png)


Linux 内核 6.6 版本新增了对英特尔的**神经处理单元（NPU）的支持**，这样的技术原先被称作通用处理器。


这项技术预计将于今年晚些时候，随着英特尔的“[Meteor Lake](https://www.intel.com/content/www/us/en/content-details/788851/meteor-lake-architecture-overview.html)”芯片亮相而首次公开登场。这些 **NPU 将被专门用于处理人工智能工作负载**。


英特尔甚至已经开始对即将发布的 “**Arrow Lake**”芯片进行**NPU 支持的初步工作**了！


此外，还新增了对英特尔的 [Shadow Stack](https://en.wikipedia.org/wiki/Shadow_stack) 的支持，因为他们的 [控制流执行技术](https://www.intel.com/content/www/us/en/developer/articles/technical/technical-look-control-flow-enforcement-technology.html)（CET）被引入到了内核中。其主要目的是防止现代英特尔 CPU（从 Tiger Lake 起）上的**返回导向编程（ROP）攻击**。


#### 对笔记本的更佳支持


![](/data/attachment/album/202310/31/204635nb3btutx6bhmx03e.png)


**对于惠普笔记本，现在你可以直接在 Linux 中对 BIOS 进行管理了**，这要归功于 “**HP-BIOSCFG**” 驱动的实现。


根据报道，**从 2018 年起出产的惠普笔记本应该都可以支持这个驱动程序**。


**对于联想笔记本，驱动程序已经更新，为更多的 IdeaPad 笔记本**添加了键盘背光控制\*\*。


同样，**对于华硕笔记本**，现在 [ROG Flow X16](https://rog.asus.com/laptops/rog-flow/rog-flow-x16-2023-series/spec/)（2023 年款）游戏笔记本，当屏幕翻转时可以**正确地启用平板模式**。


#### 网络改进
