Developers have released Linux kernel 7.0, featuring improvements for Intel and AMD hardware, enhanced storage handling, and the removal of the experimental label from Rust support. Linus Torvalds announced the update, which is not a long-term support version. The release includes preparations for upcoming CPUs and GPUs, alongside self-healing filesystem capabilities.
Linus Torvalds, the lead maintainer of the Linux kernel, announced the release of version 7.0 on April 13. This update brings widespread enhancements but is not designated as a long-term support kernel; users seeking extended stability should stick with Linux kernel 6.18, supported until December 2028. Distros like Arch Linux and Fedora will receive it soon, while others like Ubuntu may require manual installation of the mainline kernel, which carries risks to system stability. Rust support in the kernel is now officially stable, no longer marked as experimental. Intel gains audio support for the standard Nova Lake variant, expanded temperature monitoring for Arc GPUs via the HWMON interface, GSC firmware and Protected Xe Path for Panther Lake, and NTB driver support for Diamond Rapids Xeon processors to enable high-speed PCIe data transfers. AMD sees preparations for Zen 6 CPUs with performance event support for branch prediction, caches, and uncore metrics, useful for developers. KVM virtualization now supports AMD's ERAPS security feature, expanding the Return Stack Buffer for guests. Groundwork for next-generation RDNA GPUs and deeper NPU integration with Radeon hardware is also included. Storage improvements feature XFS's autonomous self-healing via the xfs_healer daemon, which repairs metadata and I/O errors on mounted filesystems; Btrfs gains direct I/O for large block sizes and an experimental remap-tree; EXT4 improves concurrent direct I/O write performance. Other changes encompass RISC-V user-space control-flow integrity, WiFi 8 Ultra-High Reliability groundwork, overhauled security bug reporting for AI tools, and sensor support for select ASUS motherboards.
