Llamafile remains one of the more interesting non-browser projects out of Mozilla in recent times that so far has a bright future...

Along with AMD's upcoming hardware enablement and other Q1 code contributions, Intel's open-source engineers remained very busy this quarter as well. Intel continues upstreaming a lot of new code not only for upcoming hardware but also a lot of exciting Linux kernel features in general, various optimizations and improvements to countless open-source user-space software projects, and their other great open-source efforts in general...

With the first quarter drawing to a close, here's a recap of the most exciting AMD Linux/open-source news from the quarter. During the past three months we've seen AMD finally publish their XDNA Linux driver for open-source Ryzen AI support, their open-source HDMI driver efforts were sadly rejected by the HDMI Forum, the AMD Zen 5 "znver5" compiler support was added to GCC 14, more AMD Zen 5 Linux kernel preparations made, and various other AMD Linux driver enhancements landed...

Disclosed last August was the AMD Inception vulnerability also known as SRSO for the Speculative Return Stack Overflow. The kernel-side patches for the AMD SRSO mitigation were quickly merged. Following that were more clean-ups and fixes to the SRSO mitigation code. It's been a quiet few months since while merged on Friday was fixing some of the mitigation code due to being ineffective...

With time Microsoft's Linux kernel contributions have extended beyond just the initial business focus on Hyper-V support and other needs for Azure as well as around Windows Subsystem for Linux (WSL) to more general contributions.

Now that the Linux 6.9 merge window is past I've begun testing out this in-development kernel on more hardware platforms in the lab. While some performance boosts like Intel Core Ultra "Meteor Lake" running faster on Linux 6.9 was to be expected given EPP tuning in the new kernel specific to those SoCs, one of the unexpected delights has been seeing AMD 4th Gen EPYC performance with some nice performance gains over Linux 6.8 stable.

Fedora 39 had hoped to use the DNF5 package manager by default as the next iteration of this package management solution for RPM-based distributions. But DNF5 wasn't ready and then delayed to Fedora 41 -- skipping over the Fedora 40 series due to the RHEL 10 branching from it and not wanting the very new DNF5 to be part of that merge. Now the change proposal has been re-filed for introducing DNF5 by default in Fedora 41...

The third iteration of that driver was posted overnight as it seeks to go into the mainline Linux kernel...

Since the mid-90's with the P6 micro-architecture for the Pentium Pro as the sixth-generation x86 microarchitecture, Intel has relied on the "Family 6" CPU ID. From there Intel has just revved the Model number within Family 6 for each new microarchitecture/core. For example, Meteor Lake is Family 6 Model 170 and Emerald Rapids is Family 6 Model 207. This CPU ID identification is used within the Linux kernel and other operating systems for identifying CPU generations for correct handling, etc. But Intel Linux engineers today disclosed that Family 6 is coming to an end "soon-ish"...

While Intel Core Ultra "Meteor Lake" has been working out well under Linux already -- especially with regards to the enticing integrated Arc Graphics -- with the in-development Linux 6.9 kernel it's looking even better for the CPU performance. Here are some initial benchmarks looking at the Intel Core Ultra 7 155H Meteor Lake performance with Linux 6.8 vs. 6.9 Git.

Open-source developer Tomeu Vizoso recently began the effort of creating an open-source, reverse-engineered driver for the Rockchip NPU found in some of the latest Rockchip SoCs. After succeeding at open-source NPU driver support for the VeriSilicon NPU IP, Vizoso took up the challenge of working on Rockchip NPU support. With his open-source user-space driver he's already got his first model running. Not only is it running but it's doing so at similar performance to the proprietary driver...

Some time ago I ran through a number of benchmarks of Google Cloud's C3D VMs powered by AMD EPYC Genoa processors. The AMD EPYC 9004 series showed terrific performance with strong generational improvements over the Intel Xeon Scalable processors. Following that a request came in to examine the PingCAP TiDB database performance given its growing popularity. In this article we'll review those benchmarks showing how GCE C3D delivers strong performance advantages for TiDB.

Samba 4.20 is out as the newest feature update to this free software implementation for SMB networking protocol support and others to enhance file/print interoperability with Microsoft Windows systems...

Besides its desktop-level customizations, further differentiating System76's Pop!_OS Linux distribution from its Ubuntu LTS package base is the tendency to roll down newer versions of the upstream Linux kernel once validated across System76's portfolio of laptops and desktops. The latest on that front is Pop!_OS now shipping with the fresh Linux 6.8 stable series...

Following several days of discussions from both sides of the table over whether SDL 3.0 should revert its Wayland over X11 preference in light of some aspects of the Wayland ecosystem support not being in good shape, for now at least SDL 3.0 is sticking to the Wayland support by default. It may be revisited though closer to release to see how the upstream support is for users of this hardware/software abstraction library widely used by cross-platform games...

Ubuntu maker Canonical has spent the past several months exploring Ubuntu x86-64-v3 based images for leveraging the x86_64 micro-architecture feature level capabilities to target the level embracing AVX/AVX2, FMA, BMI2, and other instructions supported largely since Intel Haswell and AMD Excavator era processors. As shown in benchmarks Ubuntu x86-64-v3 builds can deliver better performance for the AMD/Intel systems of the past number of years. Canonical's latest foray in this area is offering up Microsoft Azure images that are tailored for x86-64-v3...

Blender has long enjoyed faster CPU rendering under Linux compared to using Microsoft Windows. Across many different processors over the years consistently we see faster Linux CPU render performance than under Windows, though that's typically the case for most renderers. With yesterday's release of Blender 4.1, there is even faster Linux CPU render speeds. Here are some initial Blender 4.0 vs. 4.1 benchmarks...

Red Hat has made the Red Hat Enterprise Linux 9.4 Beta available to their customers this week for those wanting to test the next iteration of RHEL9...
