4 Hours Ago - NVIDIA - AutoFDO Profiling For GCC Toolchain

NVIDIA compiler engineers are looking to develop a standalone tool that could be upstreamed into the GNU Compiler Collection (GCC) codebase for generating AutoFDO profiles for consumption by GCC in turn for better benefiting from automatic feedback directed optimizations (FDO) in the name of better performance.

Less than one month after releasing ROCm 7.2.2, the ROCm 7.2.3 is now available with some minor improvements to this open-source AMD GPU compute and AI stack.

For those eager to get their hands on Valve's new Steam Controller, the gaming controller is now shipping.

Omarchy as the Arch Linux based desktop distribution using the Hyprland compositor and led by David Heinemeier Hansson "DHH" is out with a big OS update.

With the GCC 16.1 compiler released last Thursday, I have begun running more compiler benchmarks on this first GCC 16 stable feature release. GCC 16 comes heavy on new changes in being the annual feature release and delivering changes from AMD Zen 6 and Arm AGI CPU support to new C++ features and even the Algol 68 programming language front-end. It's also looking quite good in the performance department relative to the GCC 15 compiler from last year.

CachyOS is a very fast out-of-the-box Linux distribution and for those concerned about Python performance, the newest updates to this Arch Linux based distribution will provide even better performance.

The growing number of file-systems within the Linux kernel source tree is causing an ongoing burden for upstream developers maintaining the virtual file-system (VFS) code around it and associated code. As a result of the continuing rise of new file-systems being proposed for the Linux kernel, documentation is being introduced to establish clear guidelines for getting new file-systems accepted into the mainline kernel.

Since last November we've begun seeing new open-source driver activity for their next-gen GPU IP with their GFX12.1 graphics engine. GFX12 (12.0) was for the Radeon RX 9000 series RDNA4 hardware while GFX 12.1 is some new revision for yet-to-be-known products while there is also GFX13 bring-up and GFX12.5 too.

Linux 7.1-rc2 is out for testing with its accumulation of initial bug and regression fixes that have been collected over the past week since the Linux 7.1 merge window was capped off.

Brush v0.4 debuted today for this "Bourne Rusty Shell" as a Bash/POSIX-compatible shell written in the Rust programming language.

ReactOS as the "open-source Windows" operating system project striving for binary compatibility with Microsoft Windows has seen some exciting improvements this week.

This week Google announced the selected Google Summer of Code "GSoC" 2026 projects for providing stipends to student developers for engaging in different open-source projects. This year a lot of open-source projects involve AI/LLM adoption but there are also a number of other interesting student projects at large from GNOME Mutter GPU reset recovery to adding new features to FreeBSD.

It's been an interesting 2026 in Linux development with beginning to phase out i486 CPU support, dropping ISDN and amateur "ham" radio support, and other code cleaning in the name of a diminishing user base -- or perhaps even no users left -- for those running such vintage hardware with a modern, up-to-date kernel. Yet ISA sound card drivers have seen an uptick in activity.

One of the interesting GNOME-aligned application developments in recent months has been RustConn as a modern GTK4-based connection manager. RustConn allows managing SSH, RDP, VNC, SPICE, and a variety of other connections from this Rust-written application. It's been steadily tacking on more features and that effort continued with more features landing.

One of the most prominent changes with the upcoming Linux 7.1 kernel release is the introduction of the new NTFS driver in the Linux 7.1 kernel. This new driver provides more features and better performance than the Paragon NTFS3 driver that's been in the kernel the past few years and far better off than the original NTFS read-only driver that previously was in the kernel and for which this new driver is based. Needless to say it's also a big improvement over the NTFS-3G user-space FUSE driver too.

It turns out the Steam Deck OLED gaming handheld has not had working audio support with the mainline (upstream) Linux kernel since a change in late 2023 that was merged for Linux 6.8. There was an AMD ASoC audio change that inadvertently broke audio support for the Steam Deck OLED handheld but not affecting the original LCD model. Valve's downstream Steam OS kernel has compensated for this known breakage and other distributions targeting the Steam Deck OLED have carried the patch, but now there is a proper solution upstream ahead of Linux 7.1-rc2.

Miklos Szeredi of Red Hat has been developing the FUSEX file-system as an extended/experimental area for File-System in User-Space "FUSE" development.

Mike Blumenkrantz of Valve's Linux graphics team has ignited a discussion over potentially shifting some of Mesa's older GPU drivers into a new legacy Git branch in order to better support the more modern OpenGL and Vulkan drivers without having to worry about breaking the legacy drivers and to allow for better cleaning of the Mesa codebase. Among the drivers that could be impacted are the ATI/AMD R300 and R600 drivers and many smaller drivers.

A lot happened in the Linux and open-source world during the month of April. Ubuntu 26.04 LTS and Fedora 44 shipped, a lot of news around age attestation/verification laws, the Linux 7.0 kernel was released, Linux 7.1 is bringing many exciting changes as well as removing of old hardware drivers, the Ryzen 9 9950X3D2 Dual Edition CPU was released, we began testing the Intel Arc Pro B70 "BMG-G31", and much more software and hardware content that made the month interesting. Last month on Phoronix were 303 original news articles and 16 Linux hardware reviews / multi-page featured benchmark articles.

Due to Linux Mint moving to a longer development cycle with their next release not due until December, Linux Mint developers have decided to begin regularly publishing hardware enablement "HWE" ISOs with newer Linux kernel versions to provide better support for new hardware.

It's not too entirely surprising given the aggressive stance that the CachyOS Linux distribution has taken on out-of-the-box performance, but for those curious, it continues largely leading over the newly-released Ubuntu 26.04 LTS and Fedora Workstation 44 distributions for the leading performance on modern hardware.

AerynOS, the Linux distribution formerly known as Serpent OS, is out with a new monthly ISO refresh and details on other recent improvements to this original, from-scratch Linux distribution.

My initial testing of the Linux 7.1 development kernel on various systems in the lab continues going well. Aside from one main regression in a synthetic micro-benchmark appearing on multiple systems, not seeing much in the way of Linux 7.1 performance concerns thus far and seeing some nice performance gains in select workloads.

GCC 16.1 is now available as the first stable release of GCC 16 as this year's major open-source GNU compiler feature release.

That CPPC v4 support is now being worked on for the acpi_cppc Linux driver by NVIDIA engineers.

Just days after the Linux 7.1-rc1 kernel release, the Linux kernel's extensible scheduler class "sched_ext" is seeing a lot of bug fixes. Many of these bug fixes aren't just from the Linux 7.1 merge window but a number date back many kernel cycles. This uptick in bug fixes for sched_ext is coming due to increased AI code review.

Back in 2023 the Vulkan API introduced its initial Cooperative Matrix extension and necessary SPIR-V integration for helping with machine learning / AI inferencing use. Since then the cooperative matrix support has continued to be built upon for helping Vulkan in AI/ML areas. Now the OpenCL API is also introducing similar cooperative matrix extensions.
