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.

Just hours ago Valve announced the new Steam Controller along with the Steam Frame VR headset and new Steam Machine. While these new Steam hardware products won't be available until early 2026, Valve has just-now upstreamed support for the new Steam Controller to the SDL3 library.

Valve just sent over the press release announcing three new Steam Hardware devices.

With the upcoming release of Weston 15.0, this Wayland reference compositor will finally feature a Vulkan renderer. For those curious about its potential, a presentation recently outlined the current state of this Vulkan code path.

Framework Computer announced back in August that the Framework Laptop 16 would be rolling out upgrades to the AMD Ryzen AI 300 series and a GeForce RTX 5070 graphics option. Today the review embargo lifts on these new Framework 16 laptop upgrades and some Linux benchmarking of the new hardware.

As covered recently on Phoronix there has been several exciting improvements for aging AMD Radeon GCN 1.0 and GCN 1.1 era graphics cards for the open-source AMD Linux graphics driver stack. This work has been led by Timur Kristóf of Valve's Linux Open-Source Graphics Driver Group with an ultimate goal of shifting the GCN 1.0/1.1 open-source Linux driver hardware support from the aging "Radeon" kernel graphics driver over to the "AMDGPU" kernel driver already used by default for all AMD GPUs/accelerators from GCN 1.2 and newer.

Red Hat Enterprise Linux 10.1 has reached general availability with a number of enhancements to this leading enterprise Linux distribution. As with so many things in 2025, AI is a big focus for RHEL 10.1.

Back in August with the Vulkan 1.4.327 spec update was the introduction of VK_VALVE_video_encode_rgb_conversion as a Valve vendor extension. The open-source Radeon Vulkan "RADV" driver has now merged support for this extension that is being used now by Steam Link VR.

Open-source developer Tomeu Vizoso who developed the open-source and reverse-engineered "Rocket" accel driver for the Rockchip NPU and also worked on the Etnaviv/Vivante NPU support and other related code like Mesa's Teflon is teasing new NPU drivers coming in the new year.
