Last week saw the new Bcachefs features and Btrfs changes land along with XFS real-time improvements for the in-development Linux 6.14 kernel while overnight the Flash-Friendly File-System (F2FS) changes were merged for that other exciting and actively-advancing open-source file-system.

The Z3fold allocator for compressed pages was quietly deprecated several months ago with users encouraged to use zsmalloc instead. With no one vocally objecting, the Z3fold allocator code is now being positioned for removal from the Linux kernel source tree.

Building off last week's release of Wine 10.0, Hangover 10.0 is now available as this adaptation for running Windows games and applications on ARM64 Linux and other non-x86_64 CPU architectures.

The "char/misc" pull request was submitted today for the ongoing Linux 6.14 merge window and already merged to the Linux Git tree... As expected, the completed code around the NTSYNC driver has landed for better emulating the Windows NT synchronization primitives as a big win to Wine / Steam Play (Proton) Windows gaming on Linux.

In beginning the NVIDIA Blackwell Linux testing with the GeForce RTX 5090 compute performance, besides all the CUDA/OpenCL/OptiX benchmarks delivered last week a number of readers asked about AI performance and in particular the Llama.cpp performance with the RTX 5090 flagship graphics card. Here are some initial benchmarks looking at the GeForce RTX 5090 performance in Llama.cpp compared to prior RTX 40 and RTX 30 graphics cards.

Released last November following the AMD 5th Gen EPYC "Turin" server processor launch was ZenDNN 5.0 as their deep neural network library optimized for EPYC/Ryzen processors. ZenDNN 5.0 is their updated version of their neural network library that is compatible with the APIs from Intel oneDNN/DNNL and in turn can be used with the likes of PyTorch. It turns out ZenDNN 5.0 is capable of delivering a 400% performance uplift over their prior ZenDNN software release on the same hardware.

Hyprland 0.47 is out to begin a new week with some exciting enhancements to this visuals-focused Wayland compositor.

It's still not looking like triple buffering will land for GNOME 48 with the feature freeze set for next weekend. But that Mutter dynamic triple buffering support has been improved upon and now at least is working for direct scan-out situations as well as variable rate refresh (VRR).

The x86 platform driver updates have been merged for the ongoing Linux 6.14 merge window. As usual the x86 platform driver updates are predominantly to benefit the many different Intel/AMD laptops out there with various OEM vendor features/functionality. Plus within the platform-drivers-x86 space is a growing number of AMD SoC drivers for not only laptops but also desktops/servers.

With now having a Linux driver for running GPU compute workloads on the GeForce RTX 5090 (as mentioned, Linux gaming benchmarks will come following the formal R570 Linux driver release in the coming days that is better optimized for gaming), I ran some additional GPU compute benchmarks on the GeForce RTX 5090 "Blackwell" graphics card over the weekend.

In addition to all of the exciting "MM" changes for Linux 6.14 that were submitted by Andrew Morton's pull request, he also sent out the set of "non-MM" updates for the Linux 6.14 merge window.

The hardware monitoring "HWMON" subsystem updates have been merged for the Linux 6.14 kernel. As happens with most kernel releases, there are a number of already-launched desktop motherboards beginning to see working sensor monitoring support under Linux.

In a blog post dated for this past Thursday but only being made public on Sunday night, Microsoft issued an announcement open-sourcing their new NoSQL database... Where it gets weirder is that it's named DocumentDB. Amazon also has a database offering named DocumentDB albeit proprietary.

While many Linux distribution vendor kernels are already using SHA-512 for signing modules by default rather than the default SHA-1, the upstream Linux 6.14 kernel is also now switching the default over to using SHA-512 for better security.

For those looking for a heatsink fan to cool a custom build of an Ampere Altra / Altra Max server or workstation, the ARCTIC Freezer 4U-M ends up being a very potent option that offers similar performance to more expensive Ampere Altra heatsinks while providing similar performance.

While the main feature pull of new and updated kernel graphics/accelerator drivers were merged already for the ongoing Linux 6.14 merge window, an additional set of AMDGPU changes were sent out this week for squeezing into this next kernel release.

A set of patches being worked on by Oracle engineers allow for optionally sharing page table entries (PTEs) between processes. For some workloads this can equate to very significant memory savings.

Merged this week for the Linux 6.14 kernel were the various sound/audio driver updates. In addition to core API enhancements for better supporting the MIDI 2.0 specification, there is also support for some new audio hardware.

A half-year-old merge request from Igalia's Karmjit Mahil has been merged for Mesa 25.0 that is a Vulkan layer allowing for optionally limiting the amount of video memory reported to games/applications.

The RDMA subsystem updates have been merged for the Linux 6.14 kernel with a light set of changes overall and the most significant being support for the ROCEv2 protocol within the ERDMA driver.
