To much surprise, the X.Org Server Git tree saw the most commits in 2024 going all the way back to 2014... While there were many more commits than in years prior, it's not a sign of resurgence for the X.Org Server with Wayland continuing to become the dominant force on the Linux desktop...

Mere hours into 2025 and some news I didn't expect to be writing about... An Oracle engineer has posted a set of patches implementing an ALGOL 68 programming language front-end for the GNU Compiler Collection (GCC). These are work-in-progress patches for the half century old niche programming language...

During the course of 2024 there were 3,021 original news articles written on Phoronix around Linux and open-source topics... Fresh content each and every day, 99% of which was written by your's truly. It was quite an eventful year with a lot of excitement in kernel space, hardware vendors continuing to ramp up timely new hardware support, the never-ending drive for maximum performance optimizations, the continued Rust-ification of the open-source world, and much more. Here is a look back at the most popular news on Phoronix over the past year...

The hid-pidff driver exists within the Linux kernel for enabling force feedback "FF" support on various USB HID PID (Physical Interface Device) compliant devices.

RISC-V on the software front made very nice progress over the past year with a lot of Linux kernel and toolchain improvements, new targets being enabled, and new instructions being supported along with other additions for improving the overall RISC-V software ecosystem. When it comes to hardware though most of the readily available RISC-V systems are painstakingly slow and the more performant/featureful options are much harder to come by...

The Arch Linux project appears to have enjoyed a rather robust and successful 2024 with Valve continuing to make use of it as a base for their SteamOS distribution and now engaging more with upstream Arch Linux. Downstreams like CachyOS, Manjaro, and EndeavourOS continue to make it an appealing choice for enthusiasts and gamers. And then the continued improvements to Archinstall for an easy-to-use and quick installer and other enhancements overall made for a well-rounded year...

With New Year's Eve at Phoronix it means combing through Git statistics for the past year of various open-source projects among other end of year coverage... The most surprising takeaway from today's end of year exploration was seeing the Linux kernel hitting a decade low for the number of new commits this year. But not all is bad as on a line count the annual metric is comparable to more recent years...

In working toward the Debian 13 "Trixie" stable release in 2025, as a lovely New Year's Eve surprise today is the first alpha release of the Debian Installer for Trixie...

One of the unexpected twists this year was after several years of AMD quietly funding the ZLUDA developer for enabling unmodified CUDA applications to run on AMD GPUs at near-native performance, the ZLUDA atop AMD HIP code was made available and open-source following the end of the AMD contract. But then later on that ZLUDA code was taken down at the request of AMD. Back in October ZLUDA then decided to pursue a new life as an open-source multi-GPU CUDA implementation with an emphasis on AI workloads. Now as a New Year's Eve surprise, ZLUDA v4 was released as the first step to that new codebase...

The holiday between Christmas and New Year's is... Linus Torvalds' birthday on 28 December. Capping off the Linux creator's 55th birthday week is the Linux 6.13-rc5 kernel release...

Last weekend a Meta engineer posted Linux kernel patches to make use of the AMD INVLPGB instruction for broadcast TLB invalidation. The Linux kernel can in turn invalidate TLB entries on remote CPUs without needing to send IPIs and without having to wait for remote CPUs to handle those interrupts. Synthetic benchmarks shown in that patch series were very promising and thus I carried out some benchmarking over the holidays of this AMD INVLPGB support for the Linux kernel.

Back in April was the release of the Amarok 3.0 music player for KDE after a six year hiatus and their first version ported to using the Qt5 toolkit and KDE Frameworks 5.
