Jemalloc 5.3.1 was released today with next month marking four years since the prior release, jemalloc 5.3.0. While the version bump may not seem like much, jemalloc 5.3.1 comes with many performance improvements, new features, and other enhancements...

Last month we showcased GreenBoost as an open-source means of augmenting NVIDIA GPU vRAM with system RAM and NVMe storage. This memory tiering solution for NVIDIA GPUs was developed by an open-source developer with a focus on CUDA and allowing larger LLMs to be handled on graphics cards with smaller vRAM capacities. There was a setback to the project due to NVIDIA legal but now the project is going in new form and also has introduced GreenBoost-Proton for helping Linux gaming on NVIDIA hardware...

For those that had purchased a StarBook MK VI laptop 3+ years ago over the advertised support for Coreboot, Star Labs has now delivered with a Coreboot build finally available and working for this AMD Ryzen 5000 series powered laptop...

On this first day of the Linux 7.1 merge window, among the early pull requests merged were beginning to land the various VFS pull requests submitted by Christian Brauner. Among that code merged is enabling support for user.* extended attributes on sockets...

The Spack package manager is quite popular in the HPC / supercomputer space for scientific software. Even with the more selective niche than a typical general purpose OS package manager, large language models (LLMs) have already proven capable of being useful in generating new Spack packages. But there have also been some headaches involved too for Spack developers...

Last year NVIDIA announced the new CUDA Tile programming model as one of the biggest updates ever to the CUDA platform. CUDA Tile brings a virtual ISA for tile-based parallel programming and they subsequently open-sourced the CUDA Tile IR as an intermediate representation built atop LLVM's MLIR. Now they are looking to hire additional LLVM compiler engineers to help foster their CUDA Tile initiatives...

In advance of the Linux 7.1 merge window opening, Miguel Ojeda sent out all of the Rust feature updates on Friday. This includes bumping the minimum Rust version for building the Linux kernel as well as a new experimental option that can provide better performance for Rust code within the kernel, alongside other updates...

Sent out today was an initial patch series for comment on introducing the FTRFS file-system. The FTRFS proposal is more interesting than last week's VMUFAT file-system proposal...

Mold 2.41 is out as the latest major update to this high performance linker and viable alternative to the linkers from the GNU and LLVM projects...

The open-source, Rust-based Servo browser engine has been improving its Servoshell demo browser application while one of the most promising potentials for this engine is around embedded use as an alternative to the Chromium Embedded Framework (CEF). With the latest moves by Servo developers, they are making for a more compelling story for its use...

For those wishing to make use of modern OpenCL 3.0 capabilities on AMD APUs/SoCs with integrated Radeon graphics using Mesa's Rusticl driver, an improvement was merged this weekend to the RadeonSI driver ahead of this quarter's Mesa 26.1 release...

Nearly one year ago to the day I noted Linux developers were considering the removal of the Apple HFS and HFS+ file-system drivers from the kernel. They were orphaned the past decade and turning into a maintenance burden for upstream developers. But then to some surprise, a few developers stepped up to maintain the HFS(+) drivers. One year later it's proving to be a success story with more fixes for this aging Apple file-system support continuing...

Among the early pull requests sent out to Linus Torvalds even before the Linux 7.0 kernel officially released on Sunday were the Btrfs file-system updates. This feature-packed CoW file-system is seeing more performance optimizations for Linux 7.1 as well as its shutdown ioctl feature no longer being experimental and a variety of fixes...

Building off last night's release of the Linux 7.0 kernel is now the GNU Linux-libre 7.0-gnu kernel release for that downstream kernel that removes support for loading non-free-software kernel modules, blocks the loading of loadable microcode/firmware even when it means greatly reduced hardware support, and other sanitization of code in the name of software freedom...

Merged for the Linux 7.0 kernel was a power sequencing driver for PCIe M.2 connectors as part of an effort to allow describing PCIe M.2 connectors in Device Tree files. For Linux 7.1, that driver is extending support for PCIe M.2 Key E connectors...

As expected the stable Linux 7.0 kernel was just released today in marking this next kernel release. The Linux 7.0 milestone comes due to Linus Torvalds' preference of bumping the major version number after hitting X.19 as opposed to any single major change, but in any event there are a lot of great improvements and changes to find with this new kernel version. Linux 7.0 is also what's powering the upcoming Ubuntu 26.04 LTS release...

An out-of-bounds access within the Linux kernel has existed in mainline the past three years that could be exploited by an unprivileged user submitting a specially crafted certificate to the kernel...

With Linux 7.0 expected for release later today, in turn the Linux 7.1 merge window will kick off for the two week period of landing all sorts of exciting new features, changes, and removal of old features from the kernel. Here is a look at some of what is on the table for the Linux 7.1 merge window...

While the Meson build system has been capturing much of the limelight in recent years by open-source projects, the cross-platform CMake build system also shows no signs of slowing down and continues evolving with new features and functionality...

Ahead of the Linux 7.0 stable kernel release expected later today are some last minute pull requests sent out this morning. Notable for those using AMD Zen 3 hardware is addressing some bogus hardware errors that began appearing for some users on recent versions of the Linux kernel...
