Google Taps More Performance Out Of AMD Zen CPUs With BPF-CCX Scheduling

For helping with thread placement on modern AMD Zen systems with multiple CPU core complexes, Google has been developing “BPF CCX” that leverages the Linux kernel’s eBPF capabilities paired with a user-space agent for fine-grained thread control. Google has found very positive performance results out of their use of this alternative means of high performance scheduling for achieving even greater performance on AMD processors under Linux…

Auvidea X242 Carrier Board Brings Dual 10GbE and PCIe Gen 5 to Jetson T5000

Auvidea has released the X242, a high-performance carrier board designed for NVIDIA Jetson T5000 (Jetson Thor) modules. The board targets edge systems that require high-bandwidth I/O, multi-display support, and upgrade paths from earlier Jetson AGX Xavier and Orin platforms. The X242 is designed as a scalable, industrial-grade carrier board intended for commercial deployment volumes. It […]

Jackson: Debian’s git transition

Ian Jackson (along with Sean Whitton) has posted a manifesto and status
update
to the effect that, since Git repositories have become the
preferred method to distribute source, that is how Debian should be
distributing its source packages.

Everyone who interacts with Debian source code should be able to
do so entirely in git.

That means, more specifically:

  1. All examination and edits to the source should be performed via
    normal git operations.

  2. Source code should be transferred and exchanged as git data, not
    tarballs. git should be the canonical form everywhere.

  3. Upstream git histories should be re-published, traceably, as part of
    formal git releases published by Debian.

  4. No-one should have to learn about Debian Source Packages, which are
    bizarre, and have been obsoleted by modern version control.

This is very ambitious, but we have come a long way!

Linux 6.19’s Significant ~30% Performance Boost For Old AMD Radeon GPUs

For those still using old AMD GCN 1.0 “Southern Islands” or GCN 1.1 “Sea Islands” graphics cards, the upcoming Linux 6.19 kernel is a wonderful holiday gift. With Linux 6.19, the GCN 1.0/1.1 GPUs are now defaulting to the modern AMDGPU kernel driver in place of the legacy “Radeon” DRM driver that has been the default for GCN 1.1/1.0 and other ATI/AMD graphics processors of the past 2+ decades. In this article is a look at the performance benefit of now AMDGPU being the default as well as now enabling RADV Vulkan support out-of-the-box.

[$] Tools for successful documentation projects

At Open
Source Summit Japan
2025, Erin McKean talked about the challenges to
producing good project documentation, along with some tooling that can help
guide the process toward success. It is a problem that many projects
struggle with and one that her employer, Google, gained a lot of experience
with from its now-concluded Season of Docs
initiative. Through that program, more than 200 case studies of
documentation projects were gathered that were mined for common problems
and solutions, which led to the tools and techniques that McKean described.
