A new opportunity for you to help improve the upcoming OpenBSD 7.8 release has turned up. If YOU have a USB webcam you are using or would like to use with our favorite operating system, Kirill Korinsky (kirill@) would like to hear from you after testing recent snapshots.

Kirill's message to misc@ reads: Subject: Call for testing: USB webcams From: Kirill A. Korinsky <kirill () korins ! ky> Date: 2025-08-06 13:27:31 misc@, the latest snapshots for amd64 and arm64 (I haven't checked other architectures) include my recent changes to add support for H.264 streams from USB webcams.

[$] On the use of LLM assistants for kernel development

Linux Weekly News
1 hónap 1 hét óta
By some appearances, at least, the kernel community has been relatively insulated from the onslaught of AI-driven software-development tools. There has not been a flood of vibe-coded memory-management patches — yet. But kernel development is, in the end, software development, and these tools threaten to change many aspects of how software development is done. In a world where companies are actively pushing their developers to use these tools, it is not surprising that the topic is increasingly prominent in kernel circles as well. There are currently a number of ongoing discussions about how tools based on large language models (LLMs) fit into the kernel-development community.

Native NVIDIA support for AlmaLinux OS 9 and 10

Linux Weekly News
1 hónap 1 hét óta

The AlmaLinux project has announced the availability of packages to enable native NVIDIA driver support, including CUDA and Secure Boot, for AlmaLinux 9 and 10.

When AlmaLinux started just 5 years ago, this wouldn't have been possible. With NVIDIA's open source version of their graphics drivers things have changed. This open source version is slowly becoming the flagship driver, with new products being added exclusively to it. With the help of some incredible people in the open source ecosystem and the AlmaLinux community, we were able to do something that has yet to be done in the EL ecosystem - ship Secure Boot signed, open source, NVIDIA kernel modules.

Full documentation is available on the AlmaLinux wiki.

Almeida: a brief introduction on how GPU drivers work

Linux Weekly News
1 hónap 1 hét óta
Daniel Almeida continues his look at graphics drivers on the Collabora blog.

The starting point is to understand that a kernel-mode GPU driver connects a much larger UMD (user-mode driver) to the actual GPU. The UMD will actually implement APIs like Vulkan, OpenGL, OpenCL, and others. These APIs, in turn, will be used by actual programs to describe their workload to the GPU. This includes allocating and using not only the geometry and textures, but also the shaders being used to process said data into the final result. This means that a key aspect of GPU drivers is actually allocating GPU memory to house data related to the current scene being drawn so that it can actually be operated on by the hardware.

[$] Don't fear the TPM

Linux Weekly News
1 hónap 1 hét óta

There is a great deal of misunderstanding, and some misinformation, about the Trusted Platform Module (TPM); to combat this, Debian developer Jonathan McDowell would like to clear the air and help users understand what it is good for, as well as what it's not. At DebConf25 in Brest, France, he delivered a talk about TPMs that explained what they are, why people might be interested in using them, and how users might do so on a Debian system.
