Linux Kernel 5.18 Released with Graphics Driver Changes and New Hardware Support
|
||||
======
|
||||
The latest Linux Kernel 5.18 is now available as per the expected schedule without any delays. The release includes support for new hardware, and some core changes.
|
||||
|
||||
![Linux kernel 5.18 release][1]
|
||||
|
||||
[Linux Kernel 5.17][2] came loaded with support for next-gen hardware, including improvements for the Steam Deck.
|
||||
|
||||
Not to forget, every Linux Kernel release is technically exciting, and Linux Kernel 5.18 is no exception.
|
||||
|
||||
### Linux Kernel 5.18: What’s New?
|
||||
|
||||
This time around, we get to see improved support for Razer hardware, Apple Magic keyboard, AMD graphics, and numerous networking, core, and security changes.
|
||||
|
||||
#### A New Razer Driver
|
||||
|
||||
When it comes to gaming gears, the hardware support in Linux needs serious upgrades.
|
||||
|
||||
Yes, there are useful workarounds with open-source drivers. But, that’s not always the solution for every user.
|
||||
|
||||
As spotted by [Phoronix][3], a new Razer HID driver comes with Linux Kernel 5.18, which focuses on Razer BlackWidow keyboards fixing the macro key handling.
|
||||
|
||||
#### AMDGPU FreeSync Video Mode Enabled by Default
|
||||
|
||||
![][4]
|
||||
|
||||
While the support for FreeSync video was good enough, it was a temporary solution to improve the user experience with FreeSync monitors.
|
||||
|
||||
Now, with Linux Kernel 5.18, the FreeSync video mode is enabled by default ([changelog][5]). You do not have to do anything from your side to enable it with supported monitors.
|
||||
|
||||
#### Graphics Driver Updates
|
||||
|
||||
In addition to the improvements to the AMDGPU driver, you also get updates preparing for future hardware.
|
||||
|
||||
There have been changes to support higher DisplayPort rates as well.
|
||||
|
||||
#### Switch from C89 to C11 (GNU11)
|
||||
|
||||
![][6]
|
||||
|
||||
The C programming used for the Linux Kernel was limited to the old C89 standard, which lacked certain features for the current requirements.
|
||||
|
||||
So, C11 was decided to replace it considering the current compiler version requirement i.e. GCC 5.1 sounds perfectly fine with it.
|
||||
|
||||
#### Networking Tweaks
|
||||
|
||||
Linux Kernel 5.18 adds support for new wireless hardware, including MediaTek MT7916, MT7921U, and Broadcom BCM43454/6.
|
||||
|
||||
![][7]
|
||||
|
||||
When it comes to mobile solutions, support for Intel M.2 WWAN card has also been added.
|
||||
|
||||
The Realtek W89 driver now supports AP mode, 6 GHz band, and adds a hardware scan feature.
|
||||
|
||||
Several other improvements have been made to configure IPv6, and handle various protocols, including performance optimizations.
|
||||
|
||||
#### USB Improvements
|
||||
|
||||
Xen USB driver is being hardened against malicious hosts, and the USB DWC3 driver received improvements to support more hardware types.
|
||||
|
||||
You can find various other refinements in the [commit log][8].
|
||||
|
||||
#### Enhanced Apple Keyboard and Tablet Support
|
||||
|
||||
![][9]
|
||||
|
||||
Advancements were made to improve the experience with Apple Magic Keyboards, including the first-generation models.
|
||||
|
||||
Some of the fixes included correcting function-key mapping, keyboard backlight events, and the ability to report the battery level for the 2021 Magic Keyboard model when connected via USB.
|
||||
|
||||
Linux Kernel 5.18 improves input handling and makes things reliable when it comes to tablets.
|
||||
|
||||
You can find changes for new hardware, touchscreens, and other stuff in the related [commit][10].
|
||||
|
||||
#### New ARM Chip Support (Tesla FSD, Raspberry Pi Zero 2 W)
|
||||
|
||||
![][11]
|
||||
|
||||
Tesla’s full self-driving SoC is now supported with Linux Kernel 5.18. Samsung engineers made it possible to upstream into the Linux Kernel.
|
||||
|
||||
Other interesting chip additions include Qualcomm Snapdragon 625/632, and Samsung Exynos 850/7885.
|
||||
|
||||
You also find the support for Raspberry Pi Zero 2 W with Linux Kernel 5.18. In addition to the new entrants, old hardware/boards were removed as well. You can explore the [commit l][12]og to know more.
|
||||
|
||||
You can refer to the [official changelog][13] and Linus Torvald’s announcement to explore more details.
|
||||
|
||||
### How to Install Linux Kernel 5.18?
|
||||
|
||||
You should find the newer kernel listed on [Linux Kernel Archives][14]. So, you can download the [tarball][15] to test it out. Or, you can follow our [Linux Kernel upgrade guide][16] for help.
|
||||
|
||||
If you want to avoid compiling it yourself, you should wait for a few weeks for Linux distributions to push it to the repositories.

Linux 内核 5.18版本正式发布，新增显卡驱动以及硬件支持
|
||||
======
|
||||
Linux 最新的稳定版内核 5.18 版本现已如期发布，本次更细包括针对新硬件的支持以及许多其他的变化。
|
||||
|
||||
![Linux kernel 5.18 release][1]
|
||||
|
||||
[Linux 5.17 内核][2] 发布时包含了对下一代硬件的支持，同时增强了 Steam Deck的游戏体验。
|
||||
|
||||
每一代内核都包含了令人兴奋的技术进步，Linux 内核 5.18也不例外。
|
||||
|
||||
### Linux 内核 5.18 有哪些变化呢？
|
||||
|
||||
本次我们可以看到，内核针对雷蛇外设硬件、苹果外设硬件和AMD的图形增强了支持，包括一些网络、核心和安全方面的更新。
|
||||
|
||||
#### 新的雷蛇驱动
|
||||
|
||||
说到游戏装备，Linux的硬件支持亟待更新。
|
||||
|
||||
目前存在一些开源驱动程序的解决方案。但是这些方案不具有普适性，适配和支持较少。
|
||||
|
||||
正如 [Phoronix][3] 所发现的，一个新的雷蛇 HID驱动程序与 Linux 内核 5.18一同发布，它适配了雷蛇黑寡妇蜘蛛键盘，并修复了宏键此前存在的问题。
|
||||
|
||||
#### AMD 显卡特性 FreeSync 模式被默认开启
|
||||
|
||||
![][4]
|
||||
|
||||
尽管能够支持FreeSync是很好的一件事情并可以改善用户体验，但前序版本的支持仅是临时性解决方案。
|
||||
|
||||
现在在 Linux 内核 5.18版本中 ([见更新日志][5]) ，用户无需调整任何设置即可使用 FreeSync，因为这一显示模式已被默认启用。
|
||||
|
||||
#### 显卡驱动更新
|
||||
|
||||
针对当前和未来的 AMD显卡驱动进行了改进。
|
||||
|
||||
更高刷新率的DisplayPort也在这一个版本中支持。
|
||||
|
||||
#### 从 C89标准升级到 C11标准 (GNU11)
|
||||
|
||||
![][6]
|
||||
|
||||
用于Linux内核的C语言被限制在旧的C89标准中，在当前已经稍显老旧并且缺失了许多十分必要的新特性。
|
||||
|
||||
考虑到目前的编译器版本要求，C11标准和GCC5.1可以满足兼容性要求。
|
||||
|
||||
#### 网络优化
|
||||
|
||||
Linux 内核 5.18 增加了对新硬件的支持，包括联发科 MT7916、MT7921U和博通 BCM43454/6。
|
||||
|
||||
![][7]
|
||||
|
||||
针对移动端的改进包括对英特尔 M.2 WWAN 卡的支持。
|
||||
|
||||
Realtek W89 驱动现在支持AP模式、6GHz频段并增加了硬件扫描功能。
|
||||
|
||||
在配置IPv6和其他各种协议方面，通过一系列的改进提升了性能。
|
||||
|
||||
#### USB 改进
|
||||
|
||||
Xen USB驱动程序进行了改进，以抵御恶意主机，USB DWC3驱动程序也支持了更多的硬件类型。
|
||||
|
||||
其他改进详见 [更新日志][8]。
|
||||
|
||||
#### 增强对苹果键盘以及平板的支持
|
||||
|
||||
![][9]
|
||||
|
||||
当前版本针对苹果包含第一代在内的键盘的使用体验进行了优化。
|
||||
|
||||
包括功能键的映射、键盘背光以及通过USB连接时报告电池水平的能力都得到了改进。
|
||||
|
||||
Linux 内核 5.18改进了输入处理，在平板电脑上输入将变得更为容易。
|
||||
|
||||
硬件相关的改进详见 [更新日志][10]。
|
||||
|
||||
#### ARM 架构芯片的支持 (特斯拉 FSD，树莓派 Zero 2 W)
|
||||
|
||||
![][11]
|
||||
|
||||
特斯拉的全套自动驾驶SoC现在支持Linux 内核 5.18。三星工程师使其可以向上移植到 Linux 内核。
|
||||
|
||||
其他芯片支持包括高通骁龙625/632，以及三星Exynos 850/7885。
|
||||
|
||||
你还会发现对采用 Linux 内核 5.18 的树莓派 Zero 2 W受到了支持。旧的硬件/主板的支持则被同步去除。详见 [更新日志][12]。
|
||||
|
||||
你可以参考 [官方更新日志][13] 和 Linus Torvald 的官方发布获取更多信息。
|
||||
|
||||
### 如何安装 Linux 内核 5.18？
|
||||
|
||||
你可以在 [Linux Kernel Archives][14]的网站上找到最新版本的内核。你可以下载 [tarball][15] 以进行测试。你也可以参照 [Linux 内核升级指南][16] 获取帮助
|
||||
|
||||
如果想避免自己编译它，你可以稍等几周，等 Linux发行版把它推到仓库。
