ZDNet's Steven Vaughan-Nichols shares his list of "what's new and improved" in the latest Linux 6.16 kernel. An anonymous reader shares an excerpt from the report: First, the Rust language is continuing to become more well-integrated into the kernel. At the top of my list is that the kernel now boasts Rust bindings for the driver core and PCI device subsystem. This approach will make it easier to add new Rust-based hardware drivers to Linux. Additionally, new Rust abstractions have been integrated into the Direct Rendering Manager (DRM), particularly for ioctl handling, file/GEM memory management, and driver/device infrastructure for major GPU vendors, such as AMD, Nvidia, and Intel. These changes should reduce vulnerabilities and optimize graphics performance. This will make gamers and AI/ML developers happier. Linux 6.16 also brings general improvements to Rust crate support. Crate is Rust's packaging format. This will make it easier to build, maintain, and integrate Rust kernel modules into the kernel. For those of you who still love C, don't worry. The vast majority of kernel code remains in C, and Rust is unlikely to replace C soon. In a decade, we may be telling another story. Beyond Rust, this latest release also comes with several major file system improvements. For starters, the XFS filesystem now supports large atomic writes. This capability means that large multi-block write operations are 'atomic,' meaning all blocks are updated or none. This enhances data integrity and prevents data write errors. This move is significant for companies that use XFS for databases and large-scale storage. Perhaps the most popular Linux file system, Ext4, is also getting many improvements. These boosts include faster commit paths, large folio support, and atomic multi-fsblock writes for bigalloc filesystems. What these improvements mean, if you're not a file-system nerd, is that we should see speedups of up to 37% for sequential I/O workloads. If your Linux laptop doubles as a music player, another nice new feature is that you can now stream your audio over USB even while the rest of your system is asleep. That capability's been available in Android for a while, but now it's part of mainline Linux. If security is a top priority for you, the 6.16 kernel now supports Intel Trusted Execution Technology (TXT) and Intel Trusted Domain Extensions (TDX). This addition, along with Linux's improved support for AMD Secure Encrypted Virtualization and Secure Memory Encryption (SEV-SNP), enables you to encrypt your software's memory in what's known as confidential computing. This feature improves cloud security by encrypting a user's virtual machine memory, meaning someone who cracks a cloud can't access your data. Linux 6.16 also delivers several chip-related upgrades. It introduces support for Intel's Advanced Performance Extensions (APX), doubling x86 general-purpose registers from 16 to 32 and boosting performance on next-gen CPUs like Lunar Lake and Granite Rapids Xeon. Additionally, the new CONFIG_X86_NATIVE_CPU option allows users to build processor-optimized kernels for greater efficiency. Support for Nvidia's AI-focused Blackwell GPUs has also been improved, and updates to TCP/IP with DMABUF help offload networking tasks to GPUs and accelerators. While these changes may go unnoticed by everyday users, high-performance systems will see gains and OpenVPN users may finally experience speeds that challenge WireGuard.Read more of this story at Slashdot.
