It's a big day today in the open-source NVIDIA Nouveau/NVK space... The Mesa NVK driver is now officially declared a Vulkan 1.3 conformant implementation by the Khronos Group! In turn the NVK driver is no longer considered experimental and with Mesa 24.1 will build by default for x86/x86_64-based installations...

One of the limitations of AMD's open-source Linux graphics driver has been the inability to implement HDMI 2.1+ functionality on the basis of legal requirements by the HDMI Forum. AMD engineers had been working to come up with a solution in conjunction with the HDMI Forum for being able to provide HDMI 2.1+ capabilities with their open-source Linux kernel driver, but it looks like those efforts for now have concluded and failed...

Besides the integrated RDNA3 graphics making the Ryzen 8000G series desktop APUs interesting, making the AMD Ryzen 5 8500G a fun benchmarking target besides its sub-$200 price tag is having a mix of Zen 4 and Zen 4C cores. Here are some benchmarks looking at the Zen 4 vs. Zen 4C performance and power efficiency when offlining various core combinations on the Ryzen 5 8500G desktop processor.

Back in 2022 Cloudflare announced they were ditching Nginx for an in-house, Rust-written software called Pingora. Today Cloudflare is open-sourcing the Pingora framework...

Being worked on and off for several years has been FUSE read/write passthrough support for improving the performance of File-Systems in User-Space by avoiding the daemon overhead on a per-file basis where read/write operations are forwarded by the kernel directly to the lower file-system rather than the FUSE daemon. FUSE passthrough mode has shown to be a big performance win and it looks like it could be finally mainlined come Linux 6.9...

Upstreamed for Linux 6.8 is the experimental Xe kernel graphics driver that is a modern replacement to the "i915" Direct Rendering Manager driver. The Xe kernel driver targets Tigerlake graphics and newer while it won't be until Lunar Lake / Xe2 when it aims to become the default driver for Intel iGPU/dGPU graphics. For the upcoming Linux 6.9 kernel merge window are more feature changes and fixes to this new open-source Intel kernel graphics driver...

Continuing to bring-up the Wine Wayland driver for offering native Wayland support without X11/XWayland, Alexandros Frantzis opened the pull request today for enabling basic OpenGL support...

By default the AArch64 kernel on Ubuntu and other Linux distributions tend to default to a standard 4K page size but for newer AArch64 hardware especially in the server/HPC space, there can be great benefits to using a 64K page size. As it's been a while since I last ran any 64-bit ARM 4K vs. 64K kernel page size benchmarks, while having remote access to the NVIDIA GH200 I ran a fresh comparison for looking at the performance advantages to switching over to a 64K page size kernel. These new 64K kernel numbers are shown alongside the recent AMD EPYC and Intel Xeon CPU reference benchmark results for a look at how the 4K vs. 64K page size affects the overall computing landscape.

Ahead of this week's big KDE Plasma 6.0 release, the KWinFT project forked from the KDE KWin compositor code is re-branding as Theseus' Ship...

The Linux kernel has supported the Intel Hardware Feedback Interface "HFI" via the "intel_hfi" driver since 2022 for bettering supporting Core hybrid processors. The Intel HFI can be used for communicating performance and energy efficiency capabilities of individual CPU cores of the system. In turn the Linux kernel can leverage Intel HFI details for better task placement among the available CPU cores/threads. With a new patch series, the Intel HFI driver can "save tons of CPU cycles" by only enabling it when needed...

It looks like AMD will soon be announcing the ROCm 6.1 update to its open-source GPU compute stack...

Ubuntu/Canonical has for a while now promoted the prospects of Rust programming within the Linux kernel and one of their kernel engineers, Andrea Righi, wrote a Rust-written Linux scheduler with promising results that leverages eBPF for dynamically loading it at run-time. While Ubuntu isn't yet committing to using it as part of their distribution, appearing on the Ubuntu blog today was more praise for the work and even talking about the potential for a "micro-kernel design" in the future via leveraging Rust and eBPF...

Longtime AMD open-source Mesa developer Marek Olak after more than one decade working officially for AMD and years before that as an independent open-source contributor going back to the R300g days still has not run out of new performance optimizations to pursue. The most recent accomplishment for this leading Mesa contributor are some refinements to the OpenGL threading "glthread" code for lowering the memory footprint...

Intel confirmed at their MWC 2024 briefings that Granite Rapids D will debut in 2025 as the successor to Ice Lake D for Xeon D edge processors...

When it comes to neural processing unit NPU/AI accelerators for Linux there is open-source options with the likes most notably of Intel-owned Habana Labs leading the way, Intel's iVPU driver for the NPU found within Meteor Lake SoCs, AMD recently posting a Ryzen AI Linux driver, etc. When it comes to reverse-engineered efforts, the Etnaviv project has expanded its scopes from just Vivante graphics IP to also embracing the Vivante NPU IP for running workloads like TensorFlow Lite. With the latest open-source achievements, the Etnaviv NPU performance is coming incredibly close to the proprietary and official driver...

WayVNC 0.8 was released this weekend as the VNC server for wlroots-based Wayland compositors like Sway.

Sent in this morning via the "x86/urgent" pull request ahead of the Linux 6.8-rc6 kernel later today is a set of patches from Intel to ensure clearing of CPU buffers using the VERW instruction happens at the latest possible point in the return-to-userspace code path. This is being done to better protect against CPU bugs like Microarchitectural Data Sampling (MDS)...

Kent Overstreet on Saturday evening posted a set of 21 patches to overhaul the disk accounting code for the Bcachefs file-system. This change does break compatibility with the existing disk accounting on-disk format and thus will require an upgrade when moving to the new version, which may land for Linux v6.9...

Microsoft's in-house CBL-Mariner Linux distribution has routinely seen weekly-ish updates to this open-source code used within Azure, WSL, and other areas of the Redmond company.
