RISC-V processor IP purveyor SiFive just announced they have raised $400 million USD in an over-subscribed Series G financing round. This latest funding is so they can further focus on delivering high performance RISC-V designs for the data center.

In addition to RISC-V discontinuing its eXecute In Place "XIP" kernel support for Linux 7.1, there is an optimized strnlen() function coming for Linux 7.1 on RISC-V as well as some other optimized functions.

Natalie Vock of Valve's Linux graphics driver team primarily working on the RADV Vulkan driver has come up with a new interesting creation: patches to the Linux kernel and KDE for sharply improving the gaming experience for those running systems with limited amounts of video memory. Such as for graphics cards with just 8GB of dedicated vRAM, the patches now available -- initially on CachyOS for a nice out-of-the-box experience -- provide a noticeably better Linux gaming experience.

Beyond the capabilities of just the Vulkan Video API, the FFmpeg multimedia library has made interesting Vulkan-accelerated adaptations using compute shaders. With Vulkan compute they've implemented Apple ProRes video acceleration, FFV1 decode, and other features. The newest Vulkan feature now in place for FFmpeg is 360 degree video conversion.

The open-source Lemonade local AI server that enables using Ryzen AI NPUs on Linux for LLM usage as well as AMD Radeon GPU support and common x86_64 CPU support (in addition to Microsoft Windows support) is now becoming easier to embed within other apps for AI usage.

The newest Vulkan API extension now wired up for Mesa's Radeon Vulkan driver "RADV" is VK_EXT_primitive_restart_index that was introduced last week.

Miracle-WM as the Wayland compositor / window manager built atop Canonical's Mir project is out with a big new feature release. This "hackable" and i3/Sway-inspired Wayland compositor has landed a WebAssembly-based plug-in system for opening up new possibilities as well as a new Rust API with this week's v0.9 release.

Since last year the Linux kernel already supported the Microsoft Copilot key appearing on recent laptops to trigger AI agent interactions. That keyboard key is becoming more common but now three additional new keys have been standardized for additional AI integration on future PCs. Merged today for Linux 7.0 is supporting those new standardized keycodes for AI use.

TrueNAS 26 Beta released today as the initial test release for this next version of this Linux-based operating system for network attached storage (NAS) devices and more.

The Rust-based Redox OS open-source operating system provided a status update on all of their interesting development activities during the month of March. In addition to a lot of code improvements, Redox OS also enhanced its documentation as well as added an AI policy to reject any contributions relying on large language models.

At the end of March AMD announced the Ryzen 9 9950X3D2 processor with both dies having 3D V-Cache. This 16 core processor with 206MB of total cache is quit exciting and will be on sale later this month but AMD refrained from commenting on the price until today.

Last month Intel announced the Arc Pro B70 with 32GB of GDDR6 video memory for this long-awaited Battlemage G31 graphics card. This new top-end Battlemage graphics card with 32 Xe cores and 32GB of GDDR6 video memory offers a lot of potential for LLM/AI and other use cases, especially when running multiple Arc Pro B70s. Last week Intel sent over four Arc Pro B70 graphics cards for Linux testing at Phoronix. Given the current re-testing for the imminent Ubuntu 26.04 release, I am still going through all of the benchmarks especially for the multi-GPU scenarios. In this article are some initial Arc Pro B70 single card benchmarks on Linux compared to other Intel Arc Graphics hardware across AI / LLM with OpenVINO and Llama.cpp, OpenCL compute benchmarks, and also some OpenGL and Vulkan benchmarks. More benchmarks and the competitive compares will come as that fresh testing wraps up, but so far the Arc Pro B70 is working out rather well atop the fully open-source Linux graphics driver stack.

Set to be merged for the upcoming Linux 7.1 merge window is the "Yogafan" hardware monitoring driver to provide fan speed monitoring not only for Lenovo Yoga laptops but also various Legion and IdeaPad laptops too.

Intel's OpenVINO toolkit for optimizing and deploying AI inferencing across their range of hardware platforms is out with its newest quarterly feature update. There is official support for Intel's latest hardware as well as enabling more large language models and other new AI innovations for this excellent open-source Intel software project.

Google on Tuesday announced the Chrome 147 stable release to all Windows, macOS, and Linux users. There are a number of refinements in this latest routine Chrome stable update paired with various fixes and new developer capabilities.

Announced today from the PyTorch Conference EU in Paris is word that Hugging Face has contributed their Safetensors project to the PyTorch Foundation, which is an umbrella organization under the Linux Foundation for hosting AI initiatives. Safetensors aims to help mitigate arbitrary code execution risks and more.

In addition to the release today of Flatpak 1.16.4 for shipping new security fixes including a sandbox escape and the ability to delete host files, XDG-Desktop-Portal 1.20.4 is also now available with another security fix of its own to prevent sandboxed apps from being able to trash arbitrary host files.

That Flatbox app sandboxing and distribution system is out today with important security updates.

Jay is a new open-source shader compiler being developed for Intel's open-source OpenGL and Vulkan Linux drivers. Ultimately this Jay shader compiler should help in delivering better Linux graphics performance with modern Intel hardware.

For those that like to make remarks about AMD "fine wine" especially when it comes to open-source Linux drivers and/or nostalgic about feature work on really old hardware, to much amusement there are new patches today for the AMD InterWave ISA sound card from the 1990s.
