The IO_uring asynchronous I/O API for Linux is quite novel and has proven performance benefits. With time IO_uring has been adapted to other areas of the kernel like networking and now with a proposal raised by an Arm graphics driver engineer, it could potentially be adapted for use by Direct Rendering Manager (DRM) kernel graphics drivers.

Now past the launch day for the AMD EPYC 9005 series server processors and having delivered initial AMD EPYC Zen 5 benchmarks for the EPYC 9575F / EPYC 9755 / EPYC 9965 SKUs, it's onto one of my favorite areas of testing and that is the more focused benchmarks looking at different specific changes/features of new processors. Today under the benchmarking microscope is looking at the new AVX-512 512-bit data path capabilities of 5th Gen AMD EPYC compared to using a 256-bit data path or disabling AVX-512 entirely.

The drm-xe-next pull request earlier this week began preparing open-source driver support for Intel Xe3 graphics to premiere with Panther Lake processors. That code is beginning to queue for the upcoming Linux 6.13 cycle. Today a drm-intel-next pull request was sent out to prepare for more Intel Linux kernel graphics driver changes for Linux 6.13.

DRM_Log is an effort that continues to be worked on by Jocelyn Falempe at Red Hat as a new boot logger for printing the kernel messages on the screen.

With 5th Gen AMD EPYC "Turin" processors now launched, AMD provided a same-day release of their updated AMD Optimizing C/C++ Compiler "AOCC". This is AMD's downstream version of LLVM/Clang/Flang where they provide optimized AMD processor support with code that hasn't yet worked its way up into LLVM proper.

Collabora's Faith Ekstrand provided a status update yesterday at XDC 2024 Montreal around the state of the Nouveau kernel driver with the Mesa NVK Vulkan driver as a means of open-source Vulkan API support on NVIDIA GPUs.

Back in August I wrote about AMD beginning work on a new Linux driver to help with heterogeneous core CPUs. On Thursday a second iteration of the AMD HFI Linux driver patches were posted with this driver continuing to work its way toward the mainline kernel.

After the AMD Advancing AI Event yesterday where they launched AMD 5th Gen EPYC processors, Instinct product updates, and new high-end networking gear, they also put out a blog post to affirm their "commitment to open security technologies in the data center."

At the X.Org Developer's Conference (XDC 2024) happening this week in Montreal, NVIDIA shared a road-map around their Wayland plans as well as encouraging Wayland compositors to target the Vulkan API.

Last month Intel introduced their Xeon 6 "Granite Rapids" processors with up to 128 P cores, MRDIMM support, and other improvements as a big step-up in performance and power efficiency for their server processors. The Xeon 6900P series showed they could tango with the AMD EPYC 9004 Genoa/Bergamo processors in a number of areas, but Genoa has been around since November 2022... With today's AMD 5th Gen EPYC "Turin" launch, Zen 5 is coming to servers and delivers stunning performance and power efficiency. The new top-end AMD EPYC Turin processor performance can obliterate the competition in most workloads and delivers a great generational leap in performance and power efficiency. Here are our first 5th Gen AMD EPYC Turin benchmarks in looking at the EPYC 9575F, EPYC 9755, and EPYC 9965 processors across many workloads and testing in both single and dual socket configurations.

In addition to announcing the EPYC 9005 "Turin" processors and the latest on the AMD Instinct front, Lisa Su at the AMD Advancing AI event in San Francisco also announced the AMD Pensando Salina 400 DPU and AMD Pensando Pollara 400 Ultra Ethernet AI NIC.

AMD is using their Advancing AI event today to announce 5th Gen EPYC "Turin" processors. With up to 192 cores / 384 threads per socket, 17% IPC uplift, AVX-512 with a full 512-bit data path, and the Zen 5 architectural improvements, these new EPYC 9005 processors deliver a significant generational improvement over the EPYC 9004 Genoa and Bergamo processors.

Complementing the AMD EPYC 9575F / 9755 / 9965 performance benchmarks article looking at those Turin processors up against prior AMD EPYC CPUs and the Intel Xeon competition, this article is looking squarely at the 192-core EPYC 9965 "Turin Dense" processor compared to Ampere Computing's AmpereOne A192-32X flagship processor. It's an x86_64 vs. AArch64 battle at the leading 192 core count for performance and CPU power efficiency.

As part of a busy day in the CPU world, Intel has lifted the embargo on the Core Ultra 200S "Arrow Lake" desktop processors. This isn't the review embargo but just an overview on this new generation succeeding 14th Gen "Raptor Lake Refresh" on the desktop.

Alyssa Rosenzweig provided an update today at the XDC 2024 conference in Montreal on the open-source "Honeykrisp" Vulkan driver for Apple Silicon M1/M2 SoCs within Mesa and related work as part of the Asahi Linux project to provide for a nice Linux gaming experience atop the ARM-based Apple devices.

The Ubuntu 24.10 "Oracular Oriole" ISOs are now officially available as the newest six-month update to Ubuntu Linux.

While Intel Xe2 graphics have just debuted with Lunar Lake and we are awaiting Battlemage discrete GPUs with Xe2, Intel's open-source Linux driver engineers have begun work enabling Xe3 graphics! Xe3 driver work is now underway for next-generation Intel graphics.

AMD today quietly posted a new open-source Linux kernel driver for review... the AMD 3D V-Cache Performance Optimizer Driver. This AMD 3D V-Cache Performance Optimizer Driver for Linux is intended to help optimize performance on systems sporting 3D V-Cache such as the AMD Ryzen "X3D" parts and the EPYC "X" processors.

For those making use of Restartable Sequences (RSEQ) on Linux systems, there is an enticing performance optimization on the way.

The Open 3D Engine as the open-source game engine developed under the Linux Foundation umbrella and began as an advanced version of the Amazon Lumberyard engine is out with a new feature release. Open 3D Engine "O3DE" 24.09 is out today with a variety of enhancements for this cross-platform game engine.
