Ahead of the Linux 7.0 merge window closing later today with the Linux 7.0-rc1 release, the performance "perf" subsystem tooling changes were merged on Saturday. Among the notable changes here are the performance events and metrics handling for upcoming AMD Zen 6 processors.

Timur Kristóf of Valve's open-source Linux graphics driver team has been doing a fantastic job enhancing the older AMD Radeon GPU support under Linux. Last year he made enough improvements to the AMDGPU open-source driver that older Radeon GCN 1.0/1.1 dGPUs switched over to AMDGPU by default for nice performance gains, RADV Vulkan driver support out of the box, and all around better experience than using the legacy Radeon driver. He's also been fixing countless bugs affecting older AMD GPUs. There is another improvement on the way for benefiting some with aging AMD GPUs.

The upstream Linux kernel appears largely ready for Intel's next-generation Xeon Diamond Rapids processors as the successor to Granite Rapids. Most of the driver support appears to have been settled for a while with just some stragglers remaining. With the ongoing Linux 7.0 kernel one new addition for Diamond Rapids is NTB driver support.

For those dealing with Microsoft Hyper-V for virtualization, the Linux 7.0 mainline kernel has seen a number of improvements there. This work follows KVM also bringing some nice improvements in Linux 7.0.

Last week was the main feature pull of Rust programming language updates for the Linux 7.0 kernel merge window. Most notable with that pull was Rust officially concluding its "experimental" in now treating Rust for Linux kernel/driver programming as stable and here to stay. Sent out today was a round of Rust fixes for Linux 7.0 that includes preparations for the upcoming Rust 1.95 release.

The AppArmour security module for the Linux kernel, which most notably is backed by Canonical for Ubuntu, has some small improvements and fixes for Linux 7.0.

We haven't heard much about eCryptfs in recent years for that stackable in-tree Linux file-system providing per-directory encryption support. The FSCRYPT framework has shown its strong capabilities in recent years with various file-systems, Canonical hasn't been pursuing its user home directory encryption like it did years ago for the Ubuntu desktop, and full disk encryption is the most secure approach for ensuring data security on your system. But to some surprise with Linux 7.0 there are the most patches to eCryptfs that we have seen in a while.

The open-source ollama project that makes it easy to get up and running with a variety of LLMs under Windows, macOS, and Linux is out with a new release. The ollama v0.17.0 release is driven by new functionality around enhancing the OpenClaw onboarding process.

For those making use of the Ceph open-source, distributed storage platform, with the upcoming Linux 7.0 kernel they are introducing support for the AES256K key type.

Following last week's main set of DRM kernel graphics driver feature updates for Linux 7.0, merged on Friday to Linux 7.0 Git was the first round of fixes to these Direct Rendering Manager drivers. Dominating most of the code changes in this latest pull were AMDGPU fixes, including more enhancements for aging Radeon graphics processors.

AMD AOMP 23.0-0 was released overnight as the latest build of this LLVM/Clang downstream that continues to carry the very latest AMD patches focused on delivering the best support for GPU offloading to Radeon/Instinct hardware with the likes of the OpenMP and OpenACC APIs. AOMP continues to serve as a great leading-edge compiler for the best AMD GPU offloading experience until the patches ultimately work their way into upstream LLVM.

This week marked the release of KDE's Plasma 6.6 desktop as a very successful release that overall is in very robust shape and performing well. While Plasma 6.6 overall is in great shape, there are various bugs - including crash fixes - that have already been queued for the upcoming Plasma 6.6.1. KDE developers are also quite busy on the trek toward Plasma 6.7.

As some good news out of Intel today on the Linux/open-source side following last year's layoffs, they're hiring for some new Linux software development roles -- including for enhancing their Linux graphics driver stack that also includes a focus on Linux gaming with the likes of Valve's Proton (Steam Play).

Drgn is the programmable debugger developed by Meta engineer Omar Sandoval that has proven quite versatile and popular with Linux kernel developers and others. After nearly two dozen releases already, Drgn v0.1 was released this week as another big step forward for this open-source debugger.

When beginning some early Linux 7.0 kernel benchmarking this week for looking at its performance in its early development state, I started off testing on Core Ultra X7 "Panther Lake" in being hopeful for better performance with the maturing Arc B390 Xe3 graphics and the like. But I ended up finding Intel Panther Lake seeing some performance regressions on Linux 7.0. So next up I turned to an AMD EPYC Turin server since if regressions existed there at least it's much faster to carry out bisecting of the kernel performance regressions. But with that initial testing wrapped up, I didn't find any regressions like with Panther Lake and standing out were some rather enticing PostgreSQL database server performance benefits when running atop Linux 7.0.

Following GNOME 50's Mutter merging sdr-native color mode support for wide color gamut displays this week, another late addition to Mutter has now been merged ahead of next month's GNOME 50 stable release.

While we are on the horizon of seeing PCI Express 6.0 devices, there are already early Linux kernel patches beginning to surface for PCI Express 7.0.

Ahead of the Linux 7.0 merge window ending this weekend, the PHY updates were merged this week for this next major kernel release. There are some notable PHY additions particularly for Apple Silicon USB Type-C support as well as additions for Qualcomm's new Snapdragon X2 laptop SoCs.

Canonical engineer Utkarsh Gupta announced today on the behalf of the Ubuntu Release Team that the Ubuntu 26.04 "Resolute Raccoon" has entered its feature freeze.

Cloud Hypervisor 51 is now available for this Rust-based VMM focused on secure cloud computing. For what began as an Intel open-source project years ago is continuing to be largely led by Microsoft, Cyberus Tech, Tencent, Ant Group, and others.
