Latest Linux and open source news from around the web
In addition to AMDGPU finally seeing HDMI 2.1 FRL support in Linux 7.2, another change worth noting in this week's AMDGPU pull request is the continued work on enhancing the AMDGPU/AMDKFD kernel driver support for non-4K page size kernel builds. In particular this helps out with AMD graphics and ROCm for the likes of ARM and POWER...
EGLStreams was NVIDIA's original route to supporting Wayland with their official Linux graphics driver stack. Adoption was limited and driver vendors outside of NVIDIA didn't end up going with EGLStreams/EGLDevice. Thankfully, NVIDIA corrected course long ago with DMA-BUF, GBM, and KMS support that aligns with the rest of the ecosystem, and now that old code path is being removed from GNOME Mutter...
Today marks 22 years since I started Phoronix.com to focus on Linux hardware reviews. It's been quite a journey from the early state of Linux hardware support.....
The Software Engineering Radio podcast has put up an interview with graphics maintainer Dave Airlie. Much of what is in there will not be news to LWN readers, but it is an interesting overview of the life of a large-subsystem maintainer. I was talking to a few of the Rust people, and I thought: these are very young people, these are a group of people in their 20s, maybe 30s, they are a younger cohort of developers than the people I am normally used to dealing with. I thought there was maybe a good way we could bring these groups together. I think that having young people coming into the kernel using Rust is valuable... So I thought that I should be supportive of bringing Rust into the kernel.
Earlier this week I ran benchmarks of different CachyOS Linux kernel flavors that proved interesting from the performance overhead of their hardened kernel build to various other interesting performancr takeaways. One kernel flavor I hadn't tested though was their build with the BORE scheduler. Given the interest and feedback from Phoronix readers, here is an article focused on looking at the performance of the BORE scheduler for the Linux kernel on CachyOS.
Linux gets some relief in the absurd OS-level age verification law fiasco.
A new HTTP/2 Bomb DoS attack can exhaust memory on major web servers, causing denial-of-service in seconds.
I have been using ZimaCube 2 Pro for nearly a month now. Here is my experience with it, covering what has improved, what has not, and what this upgrade actually means for real use.
The current snap bundles FEX to emulate x86 Steam on ARM hardware, but that approach might be shortlived.
With this week's launch day review of the AMD Radeon RX 9070 GRE, Ubuntu 26.04 with its Linux 7.0 and Mesa 26.0 default driver stack was used for testing. That choice was made since the Ubuntu 26.04 release is still fresh, the RDNA4-based RX 9070 GRE was working without issue there, and from other RDNA4 testing knowing there isn't much uplift from the in-development Linux 7.1 kernel or the current stable Mesa 26.1 OpenGL RadeonSI / Vulkan RADV drivers. But for those interested, here are those tests...
The Tokenomics Foundation will work on vendor-neutral benchmarks for token spend, with backing from major players.
The splice() and vmsplice() system calls are meant to improve performance for certain data-movement tasks by minimizing (or avoiding altogether) system calls and the copying of data. They also have a long history of security problems. The recent flood of LLM-discovered vulnerabilities has drawn attention, once again, to splice() and vmsplice(); as a result, they may end up being removed altogether.
Blender 5.2 LTS open-source 3D graphics software is now available for public beta testing with new Fill tool, new Thin Wall mode, new Sample Sound node, a new Bevel node, and many other changes.
KDE Linux developers have dropped the Arch User Repository from the build pipeline due to security concerns; other distributions should consider doing the same.
The EFF has a blog post looking at a new bill in California that would exempt open-source operating systems from the Digital Age Assurance Act passed last year, but has problems of its own: While the open source exemption, if passed, would improve the law, the remaining amendments proposed by AB 1856 would require all web browsers and websites to request and collect users' ages. This is an expansion of last year's AB 1043's age-bracketing system that compounds its constitutional harms to users' speech, privacy, and security. [...] EFF understands this amendment to exempt open-source operating systems from the requirement to collect and transmit users' age-bracket data. That is a definite win for open-source developers. The bill is narrower now than it was before, and lawmakers clearly responded to concerns raised by EFF and the broader open-source community. Some important questions still remain—for example, it is unclear how the law would apply when an open-source operating system is
