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

10 mars 2025 à 16:57
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

10 mars 2025 à 15:30
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

10 mars 2025 à 11:52
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...

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

10 mars 2025 à 05:00
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

9 mars 2025 à 15:00
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

9 mars 2025 à 12:35
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)...

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

7 mars 2025 à 16:13
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

7 mars 2025 à 14:40
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...

Ubuntu 25.10 Planning To Use Dracut By Default

6 mars 2025 à 18:00
For the past number of months there has been talk in the Ubuntu developer space around replacing initramfs-tools with Dracut for handling initrd generation. While there has been progress in switching to Dracut, they aren't over the finish line yet and not until Ubuntu 25.10 are they planning to use Dracut by default...
