Linux 内核 6.7 发布，包含众多修复和新的文件系统
|
||||
======
|
||||
|
||||
![][0]
|
||||
|
||||
> 这是历来重大的 Linux 内核发布之一，集大量修复和新增功能于一身。
|
||||
|
||||
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][1] 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
|
||||
|
||||
![][3]
|
||||
|
||||
首先要讲的是英特尔的 [Meteor Lake][4] 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][5] 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][6] 和 Lunar Lake 芯片在 [Turbostat][7]（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
|
||||
|
||||
![][8]
|
||||
|
||||
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][9] 中有更多信息。
|
||||
|
||||
你还可以阅读关于 <ruby>[阴影堆栈][10]<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][11]）在 [Versal][12] 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][13] 中，你能了解到关于它如何实施的更多信息，我们在此对 [Phoronix][14] 的发现表示感谢。
|
||||
|
||||
#### 众多存储功能的升级
|
||||
|
||||
![][16]
|
||||
|
||||
我们终于在 Linux 内核 6.7 中迎来了 [Bcachefs][17] 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][18] 平台的支持。
|
||||
* **x86 CPU 微码加载过程** 的改进。
|
||||
* 在 [EROFS][19] 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][20] 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。
|
||||
|
||||
你可以通过阅读 [短日志][1] 或等待在 [内核档案][21] 上发布的更新日志，以了解更多的技术更新。
|
||||
|
||||
### 安装 Linux 内核 6.7
|
||||
|
||||
如果你在使用如 Arch 或 Fedora 这样的滚动版本发行版，可以期待在发行版开发者的一番测试后，就能收到升级。
|
||||
|
||||
对于其他用户，你可以安静等待，或者按照我们的简明教程， **在 Ubuntu 上升级到最新的主线 Linux 内核**：
|
||||
|
||||
> 🚧 我们并不建议你手动升级 Linux 内核，除非你的确有某些问题需要解决。
|
||||
|
||||
你可以从 [官方网站][21] 获取最新 Linux 内核版本的 tarball。但是请记住，新版本发布后需要一些时间才能下载得到。
|
||||
|
||||
> **[Linux 内核 6.7][21]**
|
||||
|
||||
💬 你打算升级到 Linux 内核 6.7 吗？你对这个版本有何评价？

Linux Kernel 6.7 Release is Loaded With Fixes and a New Filesystem
|
||||
======
|
||||
One of the biggest Linux Kernel releases, packed with fixes and a couple
|
||||
of new things.
|
||||
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][1]:
|
||||
|
||||
> 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
|
||||
|
||||
![][3]
|
||||
|
||||
We start off with Intel's [Meteor Lake][4] 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][5] processors.
|
||||
|
||||
Initial groundwork was also laid for Intel's upcoming [Arrow Lake][6] and Lunar Lake chips in [Turbostat][7], 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
|
||||
|
||||
![][8]
|
||||
|
||||
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][9] has additional information.
|
||||
|
||||
You can also read up on what a [Shadow Stack][10] 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][11]) for the [Versal][12] 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][13], and kudos to [Phoronix][14] for spotting that.
|
||||
|
||||
![][15]
|
||||
|
||||
### Many Storage Improvements
|
||||
|
||||
![][16]
|
||||
|
||||
We finally see the introduction of the [Bcachefs][17] 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][18] platform.
|
||||
* Various improvements to **x86 CPU microcode loading**.
|
||||
* **MicroLZMA compression** is now considered stable on [EROFS][19].
|
||||
* Better support for the **RISC-V powered** [Milk-V Pioneer][20] 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][1] or wait for the changelog to be available on [The Kernel Archives][21].
|
||||
|
||||
## 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:
|
||||
|
||||
![][22]
|
||||
|
||||
🚧
|
||||
|
||||
We do not recommend you to upgrade the Linux kernel manually unless you really need to resolve some issue.
|
||||
|
||||
You can source the tarball for the latest Linux kernel release from the [official website][21]. Just keep in mind that it takes some time for the latest release to be available.
