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.
