Merged a few days ago for the ongoing Linux 6.19 merge window were all of the "char/misc" updates. A lot of random changes throughout this time from the Industrial I/O "IIO" drivers to an interesting new feature for User-Space I/O "UIO" for PCI/PCIe devices...

Over the past year Intel engineers have worked a lot on Cache Aware Scheduling for the Linux kernel. The yet-to-be-merged functionality allows for the Linux kernel to better aggregate tasks sharing data to the same last level cache (LLC) domain to reduce cache misses and cache bouncing. The Cache Aware Scheduling development was led by Intel but helps other CPU vendors too for processors with multiple cache domains. Back in October I showed some nice performance wins for AMD EPYC Turin with Cache Aware Scheduling while today's article are some benchmarks of the newest CAS code and looking at the performance benefit on Xeon 6 "Granite Rapids" processors.

With the NVIDIA 590 Linux driver series removing GeForce 900 series "Maxwell" and GeForce 10 series "Pascal" as part of punting it off to the latest legacy driver branch, it's time for a last look at how the mainline NVIDIA Linux driver is performing with these aging graphics cards relative to the current state of the upstream open-source NVIDIA Linux drivers. In this article is a look at how the open-source and upstream Nouveau kernel driver with Nouveau/NVK Mesa drivers are performing relative to the NVIDIA 580 series with its Maxwell and Pascal support. For further perspective is also tossing in newer graphics cards too for providing a end-of-year GeForce 980 / 1080 / 2080 / 3080 / 4080 / 5080 series comparison between these different Linux drivers.

Early this year AMD announced the open-source GAIA project for "Generative AI Is Awesome" as a showcase of AI support atop their Ryzen AI NPUs and other hardware. That began as a Windows-only project but in September AMD added Linux support to GAIA but only using Vulkan acceleration for AI on Radeon GPUs. Now today GAIA 0.14 is available with "native" support for both macOS and Linux...

It's been months since hearing anything more about it and not being merged, but yesterday they "reintroduced" it to the Linux kernel community...

Last month the Vulkan VK_EXT_present_timing extension was merged after 5+ years in development. VK_EXT_present_timing ended up debuting at the end of November within the Vulkan 1.4.335 spec update to much excitement for providing functionality to obtain information on the presentation engine's display for accurate timing information and to assist in scheduling a present to happen no earlier than a desired time. This is a big win for helping avoid game stuttering and more while now the Mesa support for it is nearly complete and could be merged soon...

AMD previously talked of simplifying the in-box Linux support for ROCm during the second half of 2025. So far we haven't seen any groundbreaking changes from that initiative besides AMD working on various package archives/repositories to make it easier to install the latest ROCm on different Linux distributions. But today a big announcement is now public that Canonical with next year's Ubuntu 26.04 LTS release will provide official ROCm packages along with other libraries...

Yesterday I noted some early performance regressions I've found on the Linux 6.19 kernel compared to Linux 6.18 LTS stable. Those initial benchmarks were on an AMD EPYC server. Since then I've seen many of the same workloads regressing similarly on an AMD Ryzen Threadripper workstation between Linux 6.18 and Linux 6.19 Git. Given the significant impact and AMD Threadripper processors always helping out to speed-up Linux kernel build times to make for a quicker and more manageable kernel bisecting experience, here is a look at some of the results for the Linux 6.19 performance regressions.

AMD today announced their newest member of their expansive EPYC family: the EPYC Embedded 2005 series. The new AMD EPYC Embedded 2005 Series are intended primarily for networking, storage, and industrial devices while these BGA processors will likely see other interesting thin-server uses as well.
