Linux 内核 6.6 版本莅临，带来诸多变化
|
||||
======
|
||||
|
||||
![][0]
|
||||
|
||||
> 笔记本的支持得到了提升，服务器性能得到了改进，更多内容一一揭晓。
|
||||
|
||||
又到了迎接 Linux 内核新版本发布的时刻！
|
||||
|
||||
Linux 内核 6.6 的发布，是一次大规模更新，针对各类笔记本、网络硬件、处理器等提供了**大量全方位的改良**。
|
||||
|
||||
Linus Torvalds [表示][1]：
|
||||
|
||||
> 各种各样的修复散布各处，除了针对 r8152 驱动的一些重要修复外，其它的都相当小型。下面是上周的简短日志，供所有想要一探究竟、了解更多细节的读者。日志篇幅短小，可以快速翻阅。
|
||||
|
||||
### 🆕 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
|
||||
|
||||
![][3]
|
||||
|
||||
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][4]”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][5] 的支持，因为他们的 [控制流执行技术][6]（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
|
||||
|
||||
![][8]
|
||||
|
||||
**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][9]（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
|
||||
|
||||
![][10]
|
||||
|
||||
在网络方面，Linux 内核 6.6 版本带来了对如 [Atheros QCA8081][11]、**MediaTek MT7988**、**MediaTek MT7981**，[NXP TJA1120 PHY][12] 等新型硬件的**支持**。
|
||||
|
||||
同时，各类驱动程序也进行了升级，例如 **高通 Wi-Fi 7 （ath12k）驱动程序**，它现在**支持 Extremely High Throughput（EHT）PHY**。
|
||||
|
||||
此外，针对各类 Realtek（rtl8xxxu）Wi-Fi 芯片**启用了 AP 模式**。
|
||||
|
||||
关于特定于网络的变动，你可以在这个 [拉取请求][13] 中查阅更多的详细信息。
|
||||
|
||||
#### AMD 芯片的性能提升
|
||||
|
||||
![][14]
|
||||
|
||||
随着 Linux 内核 6.6 的发布，AMD 的开发人员推出了**两项尚未正式公开的新技术的支持**。
|
||||
|
||||
一项技术是对他们即将推出的 “**FreeSync Panel Replay**” 技术的支持，这一技术只用于游戏笔记本抖动屏，可以自动降低刷新率以节省电力和降低 GPU 工作负载。
|
||||
|
||||
另一项技术被称为 “**动态提速控制**”，这是一项能够**提高某些 Ryzen SoC 性能的功能**，但关于它的更多细节比较少。
|
||||
|
||||
关于它的实施，你可以在这个 [补丁序列][15] 中查阅更多的信息。
|
||||
|
||||
#### 🛠️ 其他的变化与改进
|
||||
|
||||
其他方面，还包括一些值得注意的变动：
|
||||
|
||||
* 针对 **龙芯** 的大量新特性。
|
||||
* **Rust 工具链** 升级至 v1.71.1 版本。
|
||||
* 对 **RISC-V** 和 **Btrfs** 的多项改进。
|
||||
* 完全移除了 [无线 USB][16] 和 [**Ultra-Wideband**][17] 的代码。
|
||||
* 对 **英伟达**、**英特尔** 和 **AMD** 的**开源图形驱动程序** 的众多优化。
|
||||
|
||||
你可以在 [更新日志][18] 中查阅更详细的信息。
|
||||
|
||||
### 安装 Linux 内核 6.6 版本
|
||||
|
||||
如果你的体验是像 Arch 或 Fedora 那类的滚动发行版，升级过程非常简单。
|
||||
|
||||
你只需要稍等片刻，因为这些发行版在发布更新时需要一些时间。
|
||||
|
||||
对于其他的用户，你可以等待主要版本更新，或者**根据我们的指南在 Ubuntu 中升级至最新的主线 Linux 内核**：
|
||||
|
||||
> **[在 Ubuntu 上安装最新的主线 Linux 内核][19]**
|
||||
|
||||
你可以在 [官方网站][20] 下载最新的 Linux 内核的 tarball （_发布后可能需要些时间才能得到_）。

Linux Kernel 6.6 Arrives With Numerous Refinements
|
||||
======
|
||||
Improved laptop support, server improvements, and more.
|
||||
It is time for another Linux kernel release!
|
||||
|
||||
The Linux kernel 6.6 release is a big one with **plenty of improvements across the board** for various laptops, networking hardware, processors and what not.
|
||||
|
||||
Linus Torvalds [mentions][1]:
|
||||
|
||||
_There's a random smattering of fixes all over, and apart from some
|
||||
bigger fixes to the r8152 driver, it's all fairly small. Below is the
|
||||
shortlog for last week for anybody who really wants to get a flavor of
|
||||
the details. It's short enough to scroll through._
|
||||
|
||||
**Suggested Read** 📖
|
||||
|
||||
![][2]
|
||||
|
||||
## 🆕 Linux Kernel 6.6: What's New?
|
||||
|
||||
Before we begin, just keep in mind that this is **a non-LTS release** , so not everyone is required to upgrade, unless they want the latest and greatest.
|
||||
|
||||
Anyway, let's move on to the highlights of this release:
|
||||
|
||||
* **Intel Improvements**
|
||||
* **Better Support for Laptops**
|
||||
* **Networking Improvements**
|
||||
* **AMD Enhancements**
|
||||
|
||||
|
||||
|
||||
### Intel Improvements
|
||||
|
||||
![][3]
|
||||
|
||||
Linux kernel 6.6 features **support for Intel's Neural Processing Unit** ( **NPU** ) technology, which was formerly known as the Versatile Processing Unit.
|
||||
|
||||
This tech is **set to debut with Intel's “[ **Meteor Lake**][4]” chips** later this year that will see these **NPUs exclusively being used for handling AI workloads**.
|
||||
|
||||
Intel has even begun the **initial work for NPU support** on the upcoming “ **Arrow Lake** ” chips with this kernel release!
|
||||
|
||||
Then there's the **support for Intel's[ **Shadow Stack**][5]** that came with the inclusion of their [**Control-flow Enforcement Technology**][6] (CET) into the kernel. Its main objective is to **defend against return-oriented programming (ROP) attacks** on modern Intel CPUs from Tiger Lake onwards.
|
||||
|
||||
![][7]
|
||||
|
||||
### Better Support for Laptops
|
||||
|
||||
![][8]
|
||||
|
||||
**For HP laptops** , it is now **possible to manage the BIOS from within Linux** , this is thanks to the implementation of the “ **HP-BIOSCFG** ” driver.
|
||||
|
||||
According to reports, **HP laptops from 2018 and later should work** with this driver.
|
||||
|
||||
**For Lenovo laptops** , the driver was updated to **add support for keyboard backlight control** for more IdeaPad laptops.
|
||||
|
||||
Similarly, **for ASUS laptops** , the [ROG Flow X16][9] (2023) gaming laptops can now **properly enable tablet mode** when the lid is flipped over.
|
||||
|
||||
### Networking Improvements
|
||||
|
||||
![][10]
|
||||
|
||||
On the networking side of things, Linux kernel 6.6 features **support for new hardware** such as [**Atheros QCA8081**][11], **MediaTek MT7988** , **MediaTek MT7981** , [**NXP TJA1120 PHY**][12], and more.
|
||||
|
||||
Even the **drivers have seen upgrades** , take for instance the **Qualcomm Wi-Fi 7 (ath12k) driver** , which now **supports Extremely High Throughput (EHT) PHY**.
|
||||
|
||||
Then there is the **enabling of AP mode for various Realtek (rtl8xxxu) Wi-Fi chips**.
|
||||
|
||||
More details on networking-specific changes can be found in the [pull request][13].
|
||||
|
||||
### AMD Enhancements
|
||||
|
||||
![][14]
|
||||
|
||||
With the Linux kernel 6.6 release, AMD developers have pushed **support for two new pieces of technology** that they have yet to officially announce.
|
||||
|
||||
One is support for their upcoming “ **FreeSync Panel Replay** ” technology for gaming displays (laptops only) that would automatically decrease the refresh rate to save on power and reduce GPU workload.
|
||||
|
||||
The other is called “ **Dynamic boost control** ” that is a **performance** **improving feature for some Ryzen SoCs** , details about it are quite slim.
|
||||
|
||||
More on its implementation can be found in the [patch series][15].
|
||||
|
||||
### 🛠️ Other Changes & Improvements
|
||||
|
||||
As for the rest, here are some other notable changes:
|
||||
|
||||
* Loads of new features for **LoongArch**.
|
||||
* The **Rust toolchain** was upgraded to v1.71.1.
|
||||
* Various improvements for **RISC-V** and **Btrfs**.
|
||||
* Complete removal of [**Wireless USB**][16] and [**Ultra-Wideband**][17] code.
|
||||
* Many improvements for **open-source graphics drivers** for **Nvidia** , **Intel** , and **AMD**.
|
||||
|
||||
|
||||
|
||||
You can go through the [changelog][18] for more details.
|
||||
|
||||
## Installing Linux Kernel 6.6
|
||||
|
||||
If you are running rolling-release distros such as Arch or Fedora, then it is quite straightforward to upgrade.
|
||||
|
||||
You just have to wait a bit, as these distros take their time in releasing the update.
|
||||
|
||||
As for the rest, you can either wait for a major release, or **upgrade to the latest mainline Linux kernel in Ubuntu** by following our guide:
|
||||
|
||||
![][19]
|
||||
|
||||
You can download the tarball for the latest Linux kernel from its [official website][20] ( _it takes time for it to be available after release_ ).
|
||||
