新年伊始，全新 Linux 内核发布！ ?


我们在 2024 年以 **Linux 内核 6.7 版本** 的推出开启了新的篇章，这一版本具备许多显著改进，其中包括上一版本遗漏的部分内容。


Linus Torvalds 在 [公告](https://lore.kernel.org/lkml/CAHk-=widprp4XoHUcsDe7e16YZjLYJWra-dK0hE1MnfPMf6C3Q@mail.gmail.com/T/#u) 中解释了假期引发的小幅延误：



> 
> 实际上，我们上周的工作量稍比假期前一周多些，但这不会让我觉得我们需要再进一步推迟发布。
> 
> 
> 最后的结果：6.7 版本基于提交数量（超过 17k 的非合并提交，以及 1k+ 的合并提交）来看，已经是我们有史以来发布的最大规模的内核版本之一。然而，额外的第 8 个 rc 版本主要是由于圣诞节假期的时间安排，并非大规模发布所引发的。

### ? Linux 内核 6.7：新的变化


由于 6.7 是**非长期支持版本**，你没有必须要升级到 Linux 内核 6.7 的压力，除非你急于体验 Linux 的尖端技术。


有鉴于此，我们来看看这个版本**关键的亮点**包括了哪些内容：


* **英特尔的优化**
* **增强的 RISC-V 支持**
* **针对 AMD 的特别增强**
* **众多存储功能的优化**


#### 英特尔的优化


![](/data/attachment/album/202401/10/160929e8z016ic3cpc3a3e.png)


首先要讲的是英特尔的 [Meteor Lake](https://en.wikipedia.org/wiki/Meteor_Lake) 处理器。**Linux 内核 6.7 对于英特尔 Meteor Lake 图形提供了原生支持**。在此之前，此项支持还处在 *实验性* 阶段。但现在，你可以在装备有第一代 [Core Ultra](https://www.intel.com/content/www/us/en/products/details/processors/core-ultra.html) 处理器的笔记本上全面享受到它的优势了。


另外，英特尔即将发布的 [Arrow Lake](https://en.wikipedia.org/wiki/Arrow_Lake) 和 Lunar Lake 芯片在 [Turbostat](https://www.linux.org/docs/man8/turbostat.html)（一个用于监测处理器频率、空闲统计等信息的命令行工具）中也做好了规划。


不过，也有一些支持功能被删除。


在 Linux 内核 6.7 中，**不再支持英特尔安腾 IA-64 架构**。这已经计划了好一段时间，现在，终于实现了。


#### 增强的 RISC-V 支持


![](/data/attachment/album/202401/10/160930ldzqmmu92d9x0rvc.png)


RISC-V 的一大亮点是 **引入了软件阴影调用堆栈**，这旨在保护 CPU 架构免受意外和恶意操作的影响。


此外，**在用户空间对 cbo.zero，以及在基于 ACPI 系统中对** CBO 的支持，还有许多其他杂项修复也同样进行了。这个 [合并请求](https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=d46392bbf5c6ce594669f00b8177f0b34e983f90) 中有更多信息。


你还可以阅读关于 <ruby> <a href="https://en.wikipedia.org/wiki/Shadow_stack">  阴影堆栈 </a> <rt>  Shadow Stack </rt></ruby> 的文章，以了解它更多的应用。


#### 针对 AMD 的特别增强


AMD 的 **无缝启动功能已经扩展到支持 Display Core Next 3.0 及以后版本的 GPU**。包括 Radeon RDNA2/RDNA3，以及未来发布的任何 GPU。


此功能使得系统 **平滑过渡，避免了通常随着电源按钮压下后会出现的屏幕闪烁现象**。之前，这个功能仅对 AMD 的 Van Gogh 系列 APU 开放。


接下来是 **错误检测和纠正**（[EDAC](https://en.wikipedia.org/wiki/Error_detection_and_correction)）在 [Versal](https://www.xilinx.com/products/silicon-devices/acap/versal.html) SoC 系列中的引入，它添加了一个 EDAC 驱动，支持在集成的 Xilinx DDR 内存控制器上进行 RAS 功能。


在这个 [提交信息](https://git.kernel.org/pub/scm/linux/kernel/git/ras/ras.git/commit/?h=edac-drivers&id=0fd934580ea3ea91052b999ff75017c3f08b9783) 中，你能了解到关于它如何实施的更多信息，我们在此对 [Phoronix](https://www.phoronix.com/news/AMD-Xilinx-Versal-EDAC-Linux-67) 的发现表示感谢。


#### 众多存储功能的升级


![](/data/attachment/album/202401/10/160931ephd5h1vh1op9ahh.png)


我们终于在 Linux 内核 6.7 中迎来了 [Bcachefs](https://bcachefs.org/) 文件系统的引入。如果你对它不熟悉，简单来说，它是一种**写时复制（COW）文件系统**，其重点放在可靠性和稳健表现上。


此外，Btrfs 引入了 **新的三项特性**，F2FS 现在 **支持更大的页面尺寸**，甚至 **IBM 的日志文件系统（JFS）也有所增强**。


#### ?️ 其它变化及优化


最后，还有其他一些值得注意的变化包括：


* 停止对 [MIPS AR7](https://en.wikipedia.org/wiki/Texas_Instruments_AR7) 平台的支持。
* **x86 CPU 微码加载过程** 的改进。
* 在 [EROFS](https://en.wikipedia.org/wiki/EROFS) 上，**MicroLZMA 压缩** 现在被认为是稳定的。
* 更好地支持 **采用 RISC-V 的** [Milk-V Pioneer](https://milkv.io/pioneer) 板。
* 引入 **Nouveau GPU 系统处理器（GSP）**，它为英伟达的 “Turing” 及更新的 GPU 开启了更好的体验途径。

A new year, a new Linux Kernel release!🎉

We start 2024 with the **Linux kernel 6.7 release** that sees the introduction of many improvements, including some that were left out with the previous release.

Linus Torvalds mentions the little delay because of holidays in the [announcement](https://lore.kernel.org/lkml/CAHk-=widprp4XoHUcsDe7e16YZjLYJWra-dK0hE1MnfPMf6C3Q@mail.gmail.com/T/?ref=news.itsfoss.com#u):

So we had a little bit more going on last week compared to the holiday

week before that, but certainly not enough to make me think we'd want

to delay this any further.

End result: 6.7 is (in number of commits: over 17k non-merge commits,

with 1k+ merges) one of the largest kernel releases we've ever had,

but the extra rc8 week was purely due to timing with the holidays, not

about any difficulties with the larger release.

## 🆕 Linux Kernel 6.7: What's New?

Being **a non-LTS release**, you don't have to upgrade to Linux Kernel 6.7, unless you are chasing the bleeding edge of what Linux has to offer.

So, keeping that in mind, let's take a look at the **key highlights** of this release:

**Intel Improvements****Better RISC-V Support****AMD-specific Enhancements****Many Storage Improvements**

### Intel Improvements

![intel linux kernel](https://news.itsfoss.com/content/images/2024/01/linux-kernel-6-7-chip.png)

We start off with Intel's [Meteor Lake](https://en.wikipedia.org/wiki/Meteor_Lake?ref=news.itsfoss.com) processors. **Linux Kernel 6.7 has native support for Intel Meteor Lake Graphics**. Earlier, the support was behind the *experimental* curtain. But now, you can take advantage of it properly on laptops equipped with first generation [Core Ultra](https://www.intel.com/content/www/us/en/products/details/processors/core-ultra.html?ref=news.itsfoss.com) processors.

Initial groundwork was also laid for Intel's upcoming [Arrow Lake](https://en.wikipedia.org/wiki/Arrow_Lake?ref=news.itsfoss.com) and Lunar Lake chips in [Turbostat](https://www.linux.org/docs/man8/turbostat.html?ref=news.itsfoss.com), a CLI utility for monitoring processor frequency, idle statistics, and more.

However, there has been the removal of some support too.

With Linux kernel 6.7, **support for Intel Itanium IA-64 has been dropped**. This was already in the works for quite some time, but now, it is finally done.

### Better RISC-V Support

![riscv linux kernel](https://news.itsfoss.com/content/images/2024/01/linux-kernel-6-7-riscv.png)

The highlight with RISC-V has been the **introduction of a software shadow call stack** that aims to protect the CPU architecture against accidents and malicious actions.

Additionally, **support for cbo.zero in userspace**, **CBOs in ACPI-based systems**, and many other misc fixes were also made. This [merge](https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=d46392bbf5c6ce594669f00b8177f0b34e983f90&ref=news.itsfoss.com) has additional information.

You can also read up on what a [Shadow Stack](https://en.wikipedia.org/wiki/Shadow_stack?ref=news.itsfoss.com) is for learning more about its uses.

### AMD-specific Enhancements

AMD's **seamless boot functionality has been extended to GPUs which support Display Core Next 3.0 and later**. This includes Radeon RDNA2/RDNA3, and any future GPUs.

This feature results in **a smooth transition into the system without the usual flickering of the screen** that follows a power button press. Previously, this support was only enabled for AMD's Van Gogh series of APUs.

Then there's the **implementation of error detection and correction** ([EDAC](https://en.wikipedia.org/wiki/Error_detection_and_correction?ref=news.itsfoss.com)) for the [Versal](https://www.xilinx.com/products/silicon-devices/acap/versal.html?ref=news.itsfoss.com) line of SoCs that adds an EDAC driver for the RAS features on the integrated Xilinx DDR memory controllers.

You can learn more about its implementation in the [commit](https://git.kernel.org/pub/scm/linux/kernel/git/ras/ras.git/commit/?h=edac-drivers&id=0fd934580ea3ea91052b999ff75017c3f08b9783&ref=news.itsfoss.com), and kudos to [Phoronix](https://www.phoronix.com/news/AMD-Xilinx-Versal-EDAC-Linux-67?ref=news.itsfoss.com) for spotting that.

### Many Storage Improvements

![linux kernel storage](https://news.itsfoss.com/content/images/2024/01/linux-kernel-6-7-storage.png)

We finally see the introduction of the [Bcachefs](https://bcachefs.org/?ref=news.itsfoss.com) file system with Linux kernel 6.7. For those who don't know, it is **a copy-on-write (COW) file system** that focuses on reliability and robustness.

Moreover, there are **three new features with Btrfs**, **support for larger page sizes with F2FS**, and even **IBM Journaled File-System (JFS) sees a few improvements**.

### 🛠️ Other Changes & Improvements

We wrap this one up with some other notable changes:

- Removal of support for the
[MIPS AR7](https://en.wikipedia.org/wiki/Texas_Instruments_AR7?ref=news.itsfoss.com)platform. - Various improvements to
**x86 CPU microcode loading**. **MicroLZMA compression**is now considered stable on[EROFS](https://en.wikipedia.org/wiki/EROFS?ref=news.itsfoss.com).- Better support for the
**RISC-V powered**[Milk-V Pioneer](https://milkv.io/pioneer?ref=news.itsfoss.com)board. - Inclusion of
**Nouveau GPU System Processor (GSP)**that paves the way for a better experience on Nvidia's “Turing” and newer GPUs.

For a brief look into the technical changes, refer to the [shortlog](https://lore.kernel.org/lkml/CAHk-=widprp4XoHUcsDe7e16YZjLYJWra-dK0hE1MnfPMf6C3Q@mail.gmail.com/T/?ref=news.itsfoss.com#u) or wait for the changelog to be available on [The Kernel Archives](https://www.kernel.org/?ref=news.itsfoss.com).

## Installing Linux Kernel 6.7

For those running a rolling-release distro such as Arch or Fedora, you can expect an upgrade soon enough after some testing by the distro devs.

For others, you could either play the waiting game, or **upgrade to the latest mainline Linux kernel on Ubuntu** by following our handy guide:
