ClangIR has been in development for a number of years now as a new intermediate representation for the Clang compiler. ClangIR makes use of MLIR and is higher-level than LLVM IR. With ClangIR able to preserve more C/C++ source semantics, its usage can lead to better diagnostics, code/static analysis, and more performance optimizations compared to everything lowered straight away from AST to LLVM IR. While not enabling its usage by default, LLVM stakeholders are discussing at least now building it by default.

Ahead of the Linux 7.3-rc2 kernel release due out later today, a merge causing a lot of code churn was pulled in by Linus Torvalds. This tree-wide effort converts more of the kmalloc() function calls over to the newer and superior kmalloc_obj() family of functions.

The timing on Saturday's Slackware-based Zenwalk ISO "current milestone" update is now more clear with upstream Slackware having prepared what is its first alpha release of the upcoming Slackware 16.

It's been over four years since the original release of Zenwalk 15.0 while released today is a new Zenwalk Current Milestone snapshot. This Slackware-based Linux distribution with a long history has an exciting update out for testing this weekend.

Ikey Doherty is back in the Linux distribution space. Sort of. Ikey Doherty who was the founder of the Solus Linux distribution as well as Serpent OS (now AerynOS) as well as having been employed by Intel on their Clear Linux team is back at it again in the Linux space.

NVIDIA continues building out more functionality around the open-source, upstream Nova kernel graphics driver within the Linux kernel. Making it out to the mailing list this Saturday is a set of 13 patches for introducing a NVIDIA vGPU manager and VFIO variant driver.

This week's Direct Rendering Manager (DRM) fixes that were merged ahead of Sunday's Linux 7.3-rc2 release contain a number of fixes to the open-source Nouveau driver's display support for current-generation NVIDIA Blackwell GPUs.

In addition to Linux developers focused on Apple Silicon being busy enabling functionality for the M3 and newer SoCs under the Linux kernel, there are also developers working on enabling the A18 Pro SoC used by the new, budget-friendly MacBook Neo laptop. Patches were posted this week for initial enablement of the A18 Pro and the MacBook Neo Device Tree... But even with these patches, the Linux support is still severely limited for now.

AMD is building out what they are describing as an "elite" team of developers for driving Rust code "deep into the GPU stack" from firmware to drivers, shader compilers, and other GPU software in Rust.

GNOME has been working to establish a formal request for comments (RFC) process for solving major technical questions and changes moving forward. A drafted RFC is now under discussion by GNOME stakeholders for moving this process forward.

It's been an exciting start to the month of September for KDE Plasma developers with continuing to land last minute improvements for Plasma 6.8 ahead of its official release in mid-October.

Wine 11.17 is out today as the newest bi-weekly feature development release for this software enabling Windows games and apps to run on Linux.

Yesterday AWS announced the public preview of Amazon Linux 2027 as their successor to the current Amazon Linux 2023 in-house distribution. With all the software upgrades and improvements like building packages now with link-time optimizations (LTO), enforcing x86-64-v3 builds, and other changes, I was eager to run some performance benchmarks of Amazon Linux 2023 vs. Amazon Linux 2027 in the EC2 cloud.

Last month the NetworkManager project adopted an AI coding policy where authors are responsible for 100% of the code they submit and must be able to explain it all. In an attempt to catch AI coding agents that may be trying to bypass their policy, they have added an interesting canary to the project to try to catch such AI-generated patches so they can then be automatically dealt with.

The Portable Computing Language project is out today with PoCL 7.2 as this portable, MIT-licensed OpenCL implementation that runs across various CPU architectures as well as targeting other GPUs/hardware with LLVM back-ends. Notable with PoCL 7.2 is bringing official OpenCL 3.0 conformance on x86_64 and RISC-V processors.

The annual X.Org Developer's Conference "XDC 2026" is happening later this month in Toronto. A great number of interesting talks are planned this year from new Wayland features to OpenCL over CUDA, the possibility of Vulkan Gallium, and a lot of exciting driver developments.

The Apple Silicon audio driver code within the Linux kernel is preparing to make use of the recent shared GPIO infrastructure for allowing multiple drivers / kernel components to nicely share the same GPIO lines. This should help clean things up in the mainline kernel for the Apple Silicon audio support and with a cleaner architecture than the current downstream Asahi Linux code.

A change proposal filed for what would be part of Fedora Linux 47 is on making use of Thin LTO rather than Fat LTO for link-time optimizations. With Thin LTO being more memory efficient and faster build speeds, the hope is that more Fedora packages could also use Thin LTO for packages where no link-time optimizations are currently leveraged.

Merged overnight for Mesa 26.3 are changes to Intel's graphics compiler code for supporting a new 64-bit shader addressing mode. It turns out with upcoming Nova Lake P graphics will be a big fundamental change.

Vulkan 1.4.362 is out this morning as the newest routine spec update. Making Vulkan 1.4.362 more notable beyond a couple bug fixes are two new Vulkan API extensions, both of which were worked on by Valve's Linux graphics team and one of them being a Valve vendor extension.
