Nouveau On NVIDIA Turing GPUs & Newer Will Now Prefer NVK+Zink For OpenGL

As a sign of the times for both the NVK open-source NVIDIA Vulkan driver within Mesa and the generic Zink OpenGL-on-Vulkan code, with next quarter's Mesa 25.1 release when using a NVIDIA Turing GPU or newer with the Nouveau driver stack it will now default to using Zink atop NVK for OpenGL rather than the existing NVC0 Gallium3D driver...

GNOME Dash To Panel Extension Development Being "Passed On"

The GNOME Dash To Panel extension that allows moving the dash into the GNOME main panel has proven popular with GNOME desktop users for an integrated icon taskbar and status panel on GNOME Shell. Unfortunately though one of the main developers to Charles Gagnon is "passing on" development of the extension moving forward...

AMD Announces The EPYC Embedded 9005 Series

Since last year we have continued to be impressed by the AMD EPYC 9005 "Turin" server processors while today they are announcing the EPYC Embedded 9005 line-up. The AMD EPYC Embedded 9005 Series processors are much like the EPYC 9005 series processors but with a few differences...

DRM User-Space API For Apple Silicon Graphics Posted For Review

While the Asahi AGX Gallium3D and Honeykrisp Vulkan drivers continue to be developed within mainline Mesa for supporting OpenGL and Vulkan with Apple Silicon M1/M2 SoCs, the necessary Direct Rendering Manager (DRM) kernel driver has yet to be upstreamed. But hitting the mailing list today is a patch getting the user-space API (UAPI) with more eyes on as the precursor to the actual kernel driver that is currently held up by waiting on Rust kernel abstractions to be upstreamed...

AMD EPYC 9845 Makes For A Persuasive Upgrade With Performance & Energy Efficiency

With the new AMD EPYC 9005 processors there are SKUs up to 500 Watt with the likes of the EPYC 9965 flagship at 192 cores for Turin Dense cores or 128 Turin classic cores with the EPYC 9755. But for those looking at upgrading from an existing EPYC 9004 series server and bound by the motherboard BIOS support and/or cooling/power capacity, 400 Watts is a sweet spot. Many of the existing platforms designed for EPYC 9004 Bergamo/Genoa(X) and now extended for EPYC 9005 Turin are limited to a 400 Watt TDP. With the prior AMD EPYC 9655 testing I have already shown off the great Zen 5 uplift when maintaining the same core counts as Zen 4, but even sticking to 400 Watts at the top-end is room for more. The EPYC 9845 is AMD's top-end SKU for 400 Watts or less that allows for 160 dense cores (320 threads) per socket compared to the 128 core EPYC 9754 Bergamo. Effectively the same power level and 25% more -- and better (Zen 5C) -- cores. Plus with EPYC Turin supporting the new AMD P-State CPU frequency scaling driver there is greater headroom in optimizing for power efficiency if so desired. Here is a look at how the AMD EPYC 9845 delivers a great leap to performance and power efficiency for those looking at a surprisingly robust upgrade from prior generation EPYC 9004.

Intel Preps Xe3's "Dirty Rect" Feature For Linux 6.15

Along with other exciting Intel kernel graphics driver updates submitted for the upcoming Linux 6.15 merge window, another batch of drm-intel-next code was sent out today to DRM-Next. This pull request is mostly around bug fixing and other low-level work but it does provide a new "dirty rect" feature being introduced with next-gen Intel Xe3 graphics...

Linux's ARM Apple Support Now Has Another Code Reviewer

In hopefully helping Asahi Linux reduce their downstream patch burden and helping to enhance the overall flow of new Apple Silicon related code into the mainline Linux kernel, another developer has agreed to serve as an official code reviewer over the ARM Apple bits within the Linux kernel...

The New Rust-Written NVIDIA "NOVA" Driver Submitted Ahead Of Linux 6.15

For quite a while Red Hat engineers have been developing the open-source, Rust-written NOVA driver to in effect serve as the successor to the reverse-engineered Nouveau driver that isn't too actively developed in more recent times. But unlike Nouveau's extensive range of NVIDIA GPU support, the NOVA driver is intentionally limited to the RTX 20 "Turing" GPUs and newer where there is the NVIDIA GPU System Processor (GSP) with the firmware support to leverage for an easier driver-writing experience. The very initial NOVA driver code was sent out on Sunday for DRM-Next ahead of the Linux 6.15 merge window...

Intel Preps Linux For "Platform Temperature Control" With Lunar Lake & Panther Lake SoCs

Intel's new Platform Temperature Control (PTC) feature is a hardware-based solution to manage skin and/or board temperatures of a device. Platform Temperature Control will adjust the SoC power/performance if the temperature thresholds are exceeded, which are programmed by the device manufacturer. But new Linux patches posted allow controlling the Intel Platform Temperature Control feature found with new Core Ultra Lunar Lake laptops and upcoming Panther Lake hardware...

ALGOL 68 Compiler Front-End Not Being Merged Into GCC At This Point

ALGOL 68 is an imperative programming language that's more than a half-century old and went on to inspire and influence other programming languages. It has its place in programming language history but a recently published compiler front-end for ALGOL 68 has been decided for now at least not to be upstreamed into the GNU Compiler Collection (GCC)...

Intel NPU Firmware Files Upstreamed To linux-firmware.git

For two years now the Intel IVPU accelerator driver has been part of the mainline kernel for supporting the Neural Processing Unit (NPU) that's part of the Core Ultra "Meteor Lake" CPUs and newer. Only this week though was the firmware for the Intel NPUs now upstreamed to the linux-firmware.git repository...

GCC 15 Now Enables AArch64 Early Scheduling For -O3/-Ofast Modes

The GCC "-fschedule-insns" option allows for reordering of instructions to eliminate execution stalls when required data is unavailable. This early scheduling option can be beneficial for systems with slow floating point performance or costly memory load instructions. With the upcoming GCC 15 release, AArch64 will be enabling this early scheduling optimization at the -O3 optimization level and higher...

Unofficial ROCm SDK Builder Expanded To Support More GPUs

The community-based ROCm SDK Builder is an unofficial project leveraging the open-source AMD ROCm code and making it easy to build machine learning and GPU compute software across a range of environments and helping ensure proper integration with other machine learning tools and models. The ROCm SDK Builder takes special focus on the consumer Radeon iGPUs and dGPUs that typically aren't as much of a focus for the upstream AMD ROCm stack...
