Linux Kernel 7.0 is Out With Improvements Across the Board for Intel, AMD, and Storage

The development of the Linux kernel moves fast, and the 7.0 release is no exception. Around the same time as this release, a patch queued for Linux 7.1 has kicked off what will eventually be the end of i486 CPU support in the kernel.

But that’s a story for another time. For now, let’s focus on what Linux 7.0 brings to the table.

Head penguin, Linus Torvalds, had the following words to say regarding the release:

The last week of the release continued the same “lots of small fixes” trend, but it all really does seem pretty benign, so I’ve tagged the final 7.0 and pushed it out.

I suspect it’s a lot of AI tool use that will keep finding corner cases for us for a while, so this may be the “new normal” at least for a while. Only time will tell.

Linux Kernel 7.0: What’s New?

The release is here, and before getting into the improvements, there is one thing worth getting out of the way first.

This is not a long-term support release. If your priority is stability and extended maintenance, this is not the kernel to land on. Instead, you could opt for Linux kernel 6.18, which is supported until December 2028.

Intel Upgrades

Linux 6.19 already added audio support for Intel Nova Lake S, but the standard Nova Lake (NVL) variant was left out. That’s fixed in 7.0, and the difference between the two in terms of specs is mainly in core count (4 vs. 2).

Intel Arc users get something useful too. The Xe driver now exposes a lot more temperature data through the HWMON interface. Previously you got a single GPU core reading; now you get shutdown, critical, and max temperature limits, plus memory controller, PCIe, and individual vRAM channel temperatures.

Also for Panther Lake, GSC firmware loading and Protected Xe Path (PXP) support are in.

And lastly, Diamond Rapids (the upcoming Xeon successor to Granite Rapids) gets NTB driver support, which handles high-speed data transfers between separate systems over PCIe. It is expected to be helpful for distributed storage and cluster setups.

AMD Refinements

While the Zen 6 series of CPUs are still a while out, the kernel is already getting ready for it. Linux 7.0 merges perf events and metrics support for AMD Zen 6, covering performance counters for branch prediction, L1 and L2 cache activity, TLB activity, and uncore events like UMC command activity.

All of that is mainly useful for developers and admins doing performance profiling ahead of launch, and not something the average user will notice.

For virtualization, KVM picks up support for AMD ERAPS (Enhanced Return Address Predictor Security), a Zen 5 security feature. In VM scenarios, this bumps the Return Stack Buffer from 32 to 64 entries, letting guests make full use of the larger RSB.

AMD is also laying the groundwork for next-gen GPU hardware in 7.0, enabling new graphics IP blocks for what looks like an upcoming RDNA 4 successor and another RDNA 3.5 variant.

There are also hints of deeper NPU integration with future Radeon hardware, but AMD hasn’t announced anything yet, so exact product details remain a mystery for now.

Better Storage Handling

XFS gets one of the more interesting additions this release called autonomous self-healing. A new xfs_healer daemon, managed by systemd, watches for metadata failures and I/O errors in real time and triggers repairs automatically while the filesystem stays mounted.

Btrfs picks up direct I/O support for block sizes larger than the kernel page size, falling back to buffered I/O when the data profile has duplication. There’s also an experimental remap-tree feature, which introduces a translation layer for logical block addresses that lets the filesystem handle relocations and copy-on-write operations without physically moving or rewriting blocks.

EXT4 sees better write performance for concurrent direct I/O writes to multiple files by deferring the splitting of unwritten extents to I/O completion. It also avoids unnecessary cache invalidation and forced ordered writes when appending with delayed allocation.

Miscellaneous Changes

Wrapping up this section, we have some other notable changes that made it into this release:

• RISC-V gains user-space control-flow integrity (CFI) support.
• WiFi 8 Ultra-High Reliability (UHR) groundwork lands in the networking stack.
• Security bug report documentation gets an overhaul to help AI tools send more actionable reports.
• Rust support is officially no longer experimental, with the kernel team formally declaring it is here to stay.
• ASUS motherboards, including the Pro WS TRX50-SAGE WIFI A and ROG MAXIMUS X HERO, now have working sensor support.

Installing Linux Kernel 7.0

As always, those on rolling distros like Arch Linux and other distros like Fedora and its derivatives will get this new release very soon. For others on distros like Debian, Linux Mint, Ubuntu, MX Linux, etc. You will most likely not receive this upgrade.

If that doesn’t work for you, then you could always install the latest mainline Linux kernel on your Ubuntu setup. And, this goes without saying, this is risky. If you end up borking your system, we are not to blame for it.
