Ubuntu 25.10 "Questing Quokka" is now formally open for development.

With the recently released GCC 15 (GCC 15.1) compiler besides adding new language features, enhancements to help developers in debugging build failures, and other refinements, there is the never-ending quest of compiler performance optimizations. Since the recent GCC 15.1 release candidate I've been testing this annual compiler feature release on more hardware, including several AMD 5th Gen EPYC "Turin" servers to great success compared to the prior GCC 14 stable series.

Mediatek engineers have proposed Kcompressd as a new addition to the Linux kernel to improve the efficiency of memory reclamation. Mediatek engineers testing these patches on their handheld Linux devices have found huge benefit in alleviating memory pressure and enhancing system responsiveness.

LibreOffice supports Zip compression for ODT and DOCX files, among other compression uses. There's now work beginning to be merged for supporting Zstandard (Zstd) compression moving forward.

As a follow-up to the Phoronix article a few days ago entitled A Linux 6.15 Performance Regression Hits Modern AMD CPUs, there continues to be activity to address this issue with the performance impact catching the upstream kernel developers off guard. I've tested a patch now that does address the issue while still carrying the KVM protections desired.

During the past month on Phoronix were 249 original news articles and another 23 featured Linux hardware reviews and multi-page benchmark articles. There was a lot of interesting topics in April from the launch of the Framework Laptop 13 powered by AMD Strix Point, an interesting and cheap RISC-V board coming about, the Lenovo ThinkPad X1 Carbon Gen 13 proving to be an interesting low-power Linux laptop, Ubuntu 25.04 and Fedora 42 releasing, and much more.

Sculpt OS 25.04 hasbeen released as the newest version of this general purpose OS built atop the Genode OS operating system framework.

For those that have spent any length of time in the open-source world have likely come across osuosl.org when downloading open-source projects that often are mirrored at the Oregon State University Open Source Lab (OSU OSL). The OSU OSL over the past two decades has also provided VMs for various architectures from x86 and AArch64 to POWER for CI and testing purposes to open-source projects, among many other support roles. Unfortunately, the OSU OSL risks closure this year.

Intel's AI Flame Graphs software is now open-source. This is a project that started for Intel's Tiber AI Cloud to provide more insight into AI accelerator/GPU usage and hardware profiling of the full software stack. After being an internal/customer-only software project for some months, AI Flame Graphs is now open-source.

Merged a few minutes ago to the Mesa 25.2-devel graphics driver code for the open-source Intel "ANV" Vulkan Linux driver is proper memory pool support. In turn this can deliver some magnificent performance improvements on the likes of Lunar Lake and other newer Intel graphics processors.

OpenSUSE announced the beta release today of openSUSE Leap 16.0, their next-generation Linux distribution from from SUSE Linux Enterprise 16 (SLE 16) and its new base of SUSE Linux Framework One that was previously known as the Adaptable Linux Platform (ALP).

LibreSSL 4.1 released today as the newest version of this SSL/TLS library project forked a decade ago by OpenBSD from OpenSSL.

Bytedance engineers are exploring faster inter-process communication (IPC) on Linux via a new approach they call Run Process As Library (RPAL). Their initial benchmarks of RPAL are very promising for faster Linux IPC performance.

Ben Skeggs formerly of Red Hat who had been the maintainer of the Nouveau Linux kernel driver for reverse-engineered open-source NVIDIA driver support had joined NVIDIA last year and continued his engagements with the open-source Linux community. For ending out April there's a big surprise... The NVIDIA engineer posted a set of 60 patches enabling support for NVIDIA Hopper and Blackwell GPUs atop the open-source Nouveau kernel driver.

Firefox 138 was released yesterday and wasn't particularly exciting besides enhanced profile management and Tab Groups support... Aside from that it was a pretty basic release. In turn Firefox 139 is now in beta and that release does bring some items worth mentioning like faster HTTP/3 upload performance.

AMDVLK 2025.Q2.1 was released today as the first update to this official open-source AMD Vulkan driver since the previous release in mid-March. AMDVLK 2025.Q2.1 brings new hardware support, new Vulkan API extensions, and other new features.
