Last week I wrote about how Microsoft landed a VA-API improvement in Mesa to support faster Video Acceleration API encoding with FFmpeg. That code was initially only wired up for the Microsoft D3D12 driver within Mesa for WSL use-cases, but now AMD has taken advantage of the new capability for RadeonSI Gallium3D usage with their Radeon GPUs.

Linux 6.0 Merges The AMD Performance Fix For The Old "Dummy Wait" Workaround
Linux 6.0 Merges The AMD Performance Fix For The Old "Dummy Wait" Workaround
26 September 06:48 PM EDT - AMD - Chipset Workaround - 34 Comments

This morning I called attention to some pending work around a 20 year old chipset workaround in the Linux kernel had been hurting modern AMD systems by erroneously still applying the change to modern hardware. Fortunately, that patch has now been picked up by Linus Torvalds in time for the Linux 6.0 kernel expected for its stable debut next weekend.

The review embargo just lifted for the AMD Ryzen 7000 series "Zen 4" desktop processors ahead of their retail availability this week. As such there are a few Phoronix articles today looking at these Zen 4 processors under Linux and many benchmarks whole several more follow-up articles will be coming over the weeks ahead. For the launch-day review I have the AMD Ryzen 9 7900X and 7950X processors. Let's take a look at the significant performance improvements to find with the AMD Ryzen 9 7900 series under Linux.

AMD Zen 4 AVX-512 Performance Analysis On The Ryzen 9 7950X

While much of AMD's briefings for the Ryzen 7000 desktop series were focused on gaming and other consumer workloads, one of the most exciting aspects for me with the Ryzen 7000 series is AMD now supporting AVX-512. But rather going for a 512-bit FPU data path and the possibility of reduced clock frequencies and power/thermal concerns, they employed a 256-bit "double pumping" strategy. When getting the AMD Ryzen 9 7950X in the lab, exploring the AMD Zen 4 AVX-512 performance was one of the areas I was most excited to evaluate. From the benchmarks about to be shown, AMD's initial AVX-512 implementation is promising and has me all the more excited for finding it on AMD EPYC "Genoa" processors.

Today the review embargo expires on the AMD Ryzen 7000 series desktop processors ahead of their retail availability this week. Over the past two weeks I have been testing the AMD Ryzen 9 7900X and 7950X processors as the initial review samples (I should be receiving the Ryzen 5 7600X and Ryzen 7 7700X CPUs this week, AMD is staggering their review seeding of the different models). In this article to get things started are my initial Linux gaming benchmarks with the Ryzen 9 7900X/7950X compared to an assortment of other AMD and Intel systems.

AMD engineer K Prateek Nayak recently uncovered that a ~20 year old chipset workaround in the Linux kernel still being applied to modern AMD systems is responsible in some cases for hurting performance on modern Zen hardware. Fortunately, a fix is on the way for limiting that workaround to old systems and in turn helping with performance for modern systems.

Earlier this year AMD-Xilinx announced a Linux-powered robotics starter kit making use of Xilinx's Kria KR26 SOM featuring a Zynq Ultrascale+ with four Cortex-A53 cores and Mali graphics. While robotics focused, there is a DisplayPort output and over the summer Canonical has been working to get this board playing nicely with a Wayland-powered GNOME desktop.

Solidigm P41 Plus NVMe SSD
23 September 07:21 AM EDT - Storage - 14 Comments

Up on the review block today is the Solidigm P41 Plus as a value-focused solid-state drive. Solidigm is the US company formed when SK Hynix acquired Intel's NAND/SSD business. Since forming Solidigm at the end of last year they have continued to sell products from Intel's existing SSD product line-up while last month they announced the P41 Plus as their first consumer solid-state drive of their own design. Recently I've been testing out the Solidigm P41 Plus 1TB and 2TB drives under Linux for seeing how these affordable QLC drives perform.

Radeon R600 Gallium3D Switches To Modern NIR Backend By Default
23 September 06:07 AM EDT - Radeon - R600g Switches To NIR Default - 7 Comments

After the persistent work by developer Gert Wollny with a desire to improve the aging "R600g" driver that provides open-source OpenGL support for Radeon HD 2000 through HD 6000 series graphics cards, this Gallium3D driver in Mesa 22.3 will now use the NIR back-end by default.

Linux RSEQ Patches Updated For Allowing Faster getcpu() In C Libraries
23 September 05:33 AM EDT - Linux Kernel - Faster getcpu() - 7 Comments

Restartable Sequences "RSEQ" has been one of the nice additions to the Linux kernel in recent years and can allow for faster user-space operations on per-CPU data by providing a shared data structure ABI between each user-space thread and the kernel. RSEQ has been in the process of being extended to provide even more performance benefits.

While Intel's Compute-Runtime stack is fully open-source and already provides OpenCL 3.0 support for recent generations of Intel graphics under Linux, it looks like the recently-merged "Rusticl" Rust OpenCL implementation in Mesa will soon be working too on Intel graphics hardware as an alternative OpenCL 3.0 implementation.
