Linux kernel version 6.8 brings some exciting new features and fixes throughout.
If you’re a big Linux kernel nerd, you might be shrugging your shoulders at version 6.8. After all, it’s nowhere near the size of 6.7. In fact, it’s “average” in Linus Torvalds’ humble opinion. But hey, even an average Linux release brings fixes all over the place and some cool new features!
What’s So Average About It?
In his Linux Kernel Mailing List post, Torvalds mentions, “…this looks like an average release in pretty much all respects, and we don’t have any obvious big new filesystems or architectures.” But fear not, dear Linux enthusiasts! Even without groundbreaking innovations, version 6.8 brings some noteworthy updates and fixes.
Fixes All Over the Place
This release includes numerous fixes and improvements that touch various aspects of the Linux kernel. Here are just a few:
- Improved networking buffers for better caching efficiency 🌐
- Driver fixes for the Steam Controller 🎮
- Better color management for the Steam Deck 👾
- A guest-first memory feature for KVM 💭
- A change to the Intel P-State CPU frequency scaling driver (so those CPUs will be able to hit their advertised boost speeds) 🚀
- The ability to prevent direct writes to block devices 🚫
- Improved sys call entry performance for the IBM Z architecture 💨
- Fixes to mitigate AMD RFI interference on Ryzen 7000 and 8000 laptops 🔧
- Optimizations for NUMA balancing and Deadline Scheduler 🏎️
- IRQ override quirks for various laptops 🎛️
- Improvements to the WMI bus driver 🚌
- Improvements for several Android devices 📱
The New Additions
While the focus of this release may be on fixes, there are still noteworthy new features to excite the inner tech geek in you. The most significant addition is the new Intel Xe DRM driver. This driver ensures that Linux will support future Intel graphics cards. It will also boost the performance of Intel integrated and discrete GPUs 🎮✨.
Additionally, Linux 6.8 brings support for various hardware and new technologies:
- Support for the Broadcom BCM2712 CPU found in the Raspberry Pi 5 🍓🥧
- The Bcachefs initial online filesystem check and repair 🧰
- Timing adjustment to the fscrypt keyring destruction in preparation for Btrfs’s fscrypt support ⏰
- SBI-based suspend to RAM 💤
- Host-side support for Intel’s Trust Domain Extensions (TDX) 🔒
- Intel Sierra Forest and Grand Ridge intel/cstate PMU support 🌲
- New drivers to support MPS Multi-phase mp2856/mp2857 controllers 🎛️
What Lies Ahead
Although the Linux 6.8 kernel will only be supported for a few months before being succeeded by kernel 6.9, Torvalds already has several pull requests waiting in the pipeline. He urges the community to test version 6.8 thoroughly before diving into the next exciting release.

Installing the 6.8 Kernel
If you’re eager to try out the Linux 6.8 kernel, your best bet is to wait until your distribution of choice adds it to its default repositories. However, if you simply cannot wait, you can always download the source from the kernel.org site.
