11 April 03:49 PM EDT - AMD - Generative AI Is Awesome

In addition to their efforts around the Lemonade SDK itself, AMD software engineers working on their AI initiatives continue to be investing quite a bit into the Lemonade-using GAIA, the project that originally stood for "Generative AI Is Awesome". AMD's GAIA now allows building your own custom AI agents via chatting with GAIA as well as becoming a "true desktop app" so it's easier to deploy across Windows, Linux, and macOS environments.

D7VK as the open-source project that began as a fork of DXVK in adding support for Direct3D 7 atop Vulkan has with time extended its range to also supporting Direct3D 6, 5, and 3 APIs. Out today is D7VK 1.7 in continuing to better support those vintage versions of Microsoft's Direct3D API.

A few weeks past the GNOME 50 release and there continues to be a lot of ongoing GNOME app activity worth highlighting.

Back in February we were the first to report on a new AMD "RDNA 4m" target appearing in the AMDGPU LLVM shader compiler. While part of the "RDNA 4" family, it's graphics IP version is GFX 11.7 (GFX1170) that is associated with the RDNA 3 family but with some ISA changes to align it slightly more with the newer RDNA 4 graphics IP. While the RDNA 4m AMDGPU LLVM shader compiler patches have been out for two months, the Mesa patches have only been posted this week for enabling the RADV Vulkan driver and RadeonSI Gallium3D (OpenGL) driver support.

A big kernel patch series was posted today by longtime Linux developer Thomas Gleixner. The set of 38 patches amount to some big time "spring cleaning" with addressing some code remnants still around that originated back in the very early Linux v0.1 kernel while some other code being cleaned up dates back to the Linux 1.3~2.1 kernel series from the 90's.

TUXEDO Computers' laptops received some heat in the past from upstream Linux kernel developers over their out-of-tree kernel drivers but fortunately that situation has been improving. The Uniwill driver premiered in the Linux 6.19 kernel with that OEM manufacturing many of the TUXEDO Computers laptop models. That Uniwill x86 platform driver enabled more functionality for TUXEDO hardware in the mainline kernel and has continued improving since its upstreaming. More features are on the way for Linux 7.1.

The SpacemiT K3 is exciting as one of the first RISC-V RVA23 designs coming to market. For the Linux 7.0 kernel there is initial K3 support in the mainline kernel while the upcoming Linux 7.1 merge window is expected to land more K3 enablement.

Merged back in Linux 6.19 was the ASUS Armoury driver to enhance support for the ROG Ally gaming handhelds and modern ASUS laptops. The ASUS Armoury driver enables various laptop features to be toggled under Linux and since its introduction it has continued expanding support for more ASUS devices. Ahead of Linux 7.0 coming out on Sunday, a few more devices are now supported by this upstream driver.

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.

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.

8 April 08:50 PM EDT - AI - New AI Agent Keys

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.

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.

8 April 06:29 AM EDT - Intel - OpenVINO 2026.1

7 April 10:45 AM EDT - Intel - Intel QuickAssist

The Intel QuickAssist "QAT" driver for the mainline Linux 7.1 kernel is adding support for Zstd offloading across QuickAssist Gen 4 / Gen 5 / Gen 6 accelerators for Zstandard compression as well as Zstandard decompression (limited there to the latest Gen 6 hardware).

Greg Kroah-Hartman, the main Linux stable kernel maintainer and typically viewed as the second-in-command to the Linux kernel development, has turned to new "gregkh_clanker_t1000" fuzzing tooling to help uncover new kernel bugs.

Framework Computer on Monday issued their latest update concerning the ongoing price increases for memory and solid state drives affecting the industry. There has been some more price increases, signs of some temporary reprieve, and then a bit of good news on pricing for select Framework hardware.

It looks like with the Linux 7.2 kernel later in the year the AMD ISP4 driver will finally be merged to mainline. This driver is needed for the web camera on the HP ZBook Ultra G1a Strix Halo laptop and other future AMD Ryzen laptops.

7 April 06:19 AM EDT - RISC-V - RISC-V Execute In Place

Introduced in Linux 5.13 back in 2021 was eXecute In Place "XIP" support for RISC-V that allows for the kernel image to be executed from ROM. The intent is on allowing the kernel to run from non-volatile storage like NOR flash that is directly addressable by the CPU and to reduce RAM usage. But after RISC-V XIP support is broken for months at a time, the feature is now set to be retired from the mainline kernel.

It doesn't change too much in practice with how Mesa updates typically have been handled under Fedora Linux, but now it's officially documented: Mesa graphics drivers have a permanent updates exception so new Mesa versions can be shipped as updates in Fedora stable releases.

Following last month's Lemonade SDK 10.0 release that finally makes AMD Ryzen AI NPUs under Linux useful for running large language models (LLMs) where as before the Linux build could only target GPUs, released on Monday was Lemonade 10.1 with more enhancements to this local LLM solution.
