A security disclosure has been made public today for a yet-to-be-patched arbitrary code execution vulnerability with the KDE Plasma desktop.

It's not only old x86 i486 CPU support being removed from the Linux kernel but a number of older ARM platforms and features are on the chopping block too. A proposal has been laid out for deprecating and then removing a number of outdated ARM platforms and features from the Linux kernel in early 2027.

Back in May the FFmpeg project introduced Vulkan-accelerated decoding for the APV video format. The Advanced Professional Video (APV) codec was being handled using Vulkan shaders in a similar way to how FFmpeg implemented Vulkan acceleration for Apple ProRes. Now there is Vulkan-accelerated APV encoding too.

Red Hat engineer Karol Herbst has landed his latest optimization work to Rusticl in Mesa 26.2. The latest effort for this Rust-based OpenCL driver that works across Gallium3D drivers is around better hardware utilization.

A new release of libjxl is now available for this reference implementation of the JPEG-XL image format, including both image encode and decode support.

Erin Catto who has been developing the Box2D 2D physics engine for games announced the release of Box3D. Box3D is now providing a new open-source 3D physics engine that is forked off from the Box2D code.

Stemming from the widely varying views over the recent Fedora proposal for an "AI Developer Desktop" catering to running local AI and machine learning workloads in pre-configured environments with a seamless hardware-accelerated experience, the Fedora Council issued a statement this evening to effectively shutdown discussions for now over a Fedora AI Developer Desktop and to pause the Fedora Community Initiatives process.

Back in March Steam on Linux use shot up to 5.33% as a big 3.1% improvement over February. In April it dropped to 4.52% and then fell to 3.99% in May. Valve just published the Steam Survey numbers for June and it points to another minor setback from the recent all-time high of Steam on Linux.

With the start of the new month comes a new progress report on the KDE Linux distribution for the prior month. Even with KDE developers being busy to ship Plasma 6.7 in June, they still accomplished a lot when it comes to KDE Linux.

System76 today announced their new Lemur Pro high-end Linux laptop that is now powered by the Core Ultra Series 3 "Panther Lake" SoCs.

While the Linux 7.2 feature merge window ended just days ago and the better part of two months now before v7.2 will be released as stable, there are already features beginning to accumulate that will target the Linux 7.3 cycle. The most exciting change I've seen to kick off that dance ahead of Linux 7.3 is addressing a "significant" bottleneck affecting small direct I/O performance with speedy storage such as PCIe Gen5 NVMe SSDs.

Earlier this year AMD disclosed the RMPOPT instruction that given the timing will seemingly be introduced with upcoming Zen 6 EPYC "Venice" processors. The RMPOPT feature amounts to a performance optimization for AMD EPYC SEV-SNP enabled servers by cutting down on the associated Reverse Map Table (RMP) overhead. Linux enablement of AMD RMPOPT remains ongoing and out this week is the latest iteration of the enablement.

Red Hat has contributed new system-wide tunables infrastructure to the GNU C Library "glibc" that allows specifying system-wide tunables via the new /etc/tunables.conf configuration file.

Timur Kristóf of Valve's Linux graphics driver team continues taking special focus on AMD Radeon GCN 1.0 and GCN 1.1 era GPUs for enhancing the open-source graphics driver support for these aging graphics cards.

For those that prefer waiting until the first bug-fix/point release before upgrading to a major new feature series, GCC 16.2 is being planned for an early August release for delivering back-ported bug fixes to the GCC 16 compiler.

Last month on Phoronix there were 294 original news articles and 18 Linux hardware reviews / multi-page benchmark articles. Beyond Phoronix.com turning 22 years old in June, there were also a lot of exciting Linux hardware and open-source software developments worth recapping.

With modern laptops, proper platform/WMI drivers are becoming more depended upon not only for supporting all typical functionality from keyboards to backlights and other handling, but also for achieving proper performance. For many laptop vendors, the Linux platform drivers are maintained by the open-source community and actual customers. The latest example of the challenges of the community-maintained support rather than from the vendor is with the ASUS ROG Strix G16 G614PR gaming laptop seeing inappropriate power values set in the open-source driver that were incorrect and led to lower power/performance than Windows.

The Asahi Linux project published a new blog post outlining recent development efforts in getting Apple Silicon hardware working with their downstream Linux distribution. There is ongoing work on bringing up Apple M3 support, fixing boot support for macOS 27 beta systems, Apple Video Decoder (AVD) support progress, and more.

NVIDIA engineers have been developing a new binary format for their GPU firmware images for use with the in-development, open-source Nova kernel driver. With this new TLV binary firmware format it aims to be easier to parse by their Rust-based driver code.

As the last planned article on Phoronix of Q2, here is a look back at what excited readers the most in the second quarter. There were 872 original news articles this quarter as well as 54 Linux hardware reviews / multi-page featured benchmark articles. Here is what excited readers the most over these past three months.
