Introduced last year in the Linux 6.10 kernel was the mseal system call for memory sealing to protect the memory mapping against modifications to seal non-writable memory segments or better protecting sensitive data structures. The GNU C Library has finally introduced its mseal function making use of this modern Linux kernel functionality.

Following the mainline Linux kernel support for the VisionFive 2 RISC-V single board computer from StarFive, Linux kernel patches are on the way for their new VisionFive 2 Lite low-cost offering. With the StarFive VisionFive 2 Lite this RISC-V board can be procured for as little as $19.9 USD as one of the cheapest yet fairly capable RISC-V SBCs.

Intel driver engineer Suraj Kandpal presented at the recent X.Org Developer's Conference (XDC2025) on the challenges around supporting content protection on Linux such as for High-bandwidth Digital Content Protection (HDCP) and Protected Audio Video Path (PAVP).

Fedora 44 is looking at replacing the Linux kernel's console "FBCON" with the user-space-based KMSCON implementation. Eventually the hope remains to deprecate the FBCON/FBDEV code within the Linux kernel.

Compiler engineer Marek Polacek of Red Hat recently proposed making the C++20 language specification (or rather the GNU++20 dialect) the default C++ version when not otherwise specified.

The EROFS read-only file-system started by Huawei and now maintained by a growing number of contributors continues attracting even more interest. EROFS has exhibited much potential for mobile devices as well as container use-cases while proving itself to be quite robust since its mainlining back in 2019.

Valve and CodeWeavers today released Proton 10.0-3 as the newest stable update to this Wine-based software that powers Steam Play for enabling countless Windows games to run often extremely well under Linux.

Following the recent patch proposal for moving AMD GCN 1.1 generation GPUs over to the AMDGPU Linux driver by default in place of the legacy Radeon driver, a similar patch has now been proposed for the GCN 1.0 graphics processors. AMD GCN 1.0/1.1 GPUs are at parity with the AMDGPU driver to the Radeon driver while needing this newer kernel driver for enjoying RADV Vulkan support, better performance, and overall a better experience.

For those making use of the out-of-tree Bcachefs file-system driver, rolling out to the snapshot/nightly testing channel is the long-in-development "rebalance_v2" functionality now known as the "bcachefs_metadata_version_reconcile" feature.

Back in early September we reported on a Linux hardware enablement leader planning to leave Red Hat. Hans de Goede has been a longtime contributor to improving Intel/AMD Linux desktop/laptop hardware support and in fact an x86 platform drivers subsystem maintainer. We now found out where this lead Linux x86 driver developer ended up: Qualcomm.

Last week the Microsoft Azure HBv5 instances reached general availability as powered by the custom EPYC 9V64H CPUs with HBM3 memory. These very interesting EPYC processors for memory bandwidth intensive workloads were announced last year while have finally reached GA with jaw-dropping results for software able to take advantage of the 6.7 TB/s memory bandwidth thanks to the HBM memory. The Azure HBv5 benchmarks last week showed how they compare to prior generation HBv4 instances while this article is taking things further and putting the performance into perspective against the older HBv2 and HBv3 instances.

Patches posted to the Linux kernel mailing list this week are seeking to remove SHA1 support for signing of kernel modules. This is part of the larger effort in the industry for moving away from SHA1 given its vulnerabilities to hash collisions and superior hashing algorithms being available.

CUDA 13.0 Update 2 is now available as the latest incremental improvement to NVIDIA's compute stack.

For next quarter's Mesa 26.0 release, the AMD RadeonSI Gallium3D driver will present OpenGL mesh shaders support. It's been a long journey from the GL_EXT_mesh_shader extension being crafted and merged to wiring up the Mesa driver support while now it's in place for the AMD Radeon Linux graphics driver.

The Linux kernel's port to the DEC Alpha processors remains alive over 30 years after these processors first appeared.

Miracle-WM 0.8 was released on Wednesday as another step forward for this tiling Wayland compositor built atop Canonical's Mir software. Canonical engineer Matthew Kosarek continues driving new features into Miracle-WM as it works toward its v1.0 milestone.

Recently when Intel contributed Nova Lake support for LLVM/Clang and the GCC compiler support there was not any AVX10 or APX support contrary to rumors and expectations. Intel has now published a new programming reference manual where they now confirm Nova Lake will in fact support AVX10.2 and APX.

Canonical announced today the expansion of the legacy add-on for Ubuntu Pro to provide total coverage of Ubuntu LTS releases up to 15 years.

Back in April PostgreSQL added AVX-512 support for CRC32 computations. At the time the gains for CRC32 computations with this popular open-source database server were reported to be 50% to 3x faster for x86_64 CPUs able to leverage AVX-512. That AVX-512 support is found with PostgreSQL 18.0 that released in September and now Intel is praising this addition to PostgreSQL for which their developers also had a part in along with AWS and others.

Eric Engestrom today released Mesa 25.2.7 as the newest bi-weekly point release for this stable set of open-source (predominantly) OpenGL and Vulkan drivers for Linux systems.
