Merged for the Linux 6.13 kernel was the AMD 3D V-Cache Optimizer driver for being able to influence the kernel's scheduling decisions on AMD processors where only a subset of CCDs have the larger 3D V-Cache. With this new driver users can communicate their cache vs. frequency preference for influencing where new tasks are first placed if on the CCD with the larger L3 cache or with the higher frequency potential. Here is a look at the impact of using the AMD 3D V-Cache Optimizer driver with the new AMD Ryzen 9 9950X3D.

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...

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.

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...
