An ARM Linux engineer leveraged AI/LLMs to help uncover some improvements to "significant speed up" the Linux kernel build times. In the process the LLM used generated "a lot of code, much of it hideous" but in the end was used to find some very significant time savings for faster kernel builds via more task parallelization in different areas of the kernel build process.
One week after releasing systemd 262-rc1, systemd 262-rc2 is now available with further fixes and refinements for this init system and service manager. Systemd is also the latest open-source project introducing an AI canary for aiming to detect AI/LLM-based code contributors that weren't reviewed by an actual person in advance of the pull request.
An interesting new open-source project for those looking to make use of NVIDIA DLSS 5 on Linux is DLSS5VKLayer. The DLSS5VKLayer is a Linux Vulkan layer that works for both native Linux games as well as Steam Play (Proton) Windows games for experimental DLSS 5 support.

CHUWI recently launched the UniBook laptop powered by the Intel Core 3 304 "Wildcat Lake" SOC and priced at just $449 USD. Especially with today's high component pricing, a brand new sub-$500 laptop is extremely rare. Rather than using some dated SoC, it uses Wildcat Lake as Intel's new value option alternative to the Core 3 Series Ultra "Panther Lake" SoCs. This was our first time testing out Intel Wildcat Lake and that SoC plus the overall CHUWI UniBook has been working out well on Linux for those looking at a laptop in the sub-$500 space.

Asahi Linux developers announced today that they are now officially supporting the Linux distribution on Apple M3 powered Macs. With the exception of the Mac Studio M3 Ultra, other M3 / M3 Pro / M3 Max devices should now work with the latest Asahi Linux builds but with some feature caveats.
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.
