WineConf as what had been the regularly hosted Wine developer conference for this open-source project devoted to running Windows games/applications on Linux and other platforms is likely over. Due to dwindling attendance and no one stepping up to organize the next WineConf, the developer conference is on hiatus but in place there may end up being something like a Proton conference in the future...

The most common request from my recent ROG Ally benchmarking with the Ryzen Z1 SoC and also the Ryzen 7 7840U laptop SoC testing has been wanting to know how these Zen 4 mobile processors compete with Apple's M2 on Linux. Well, for those curious, here are some initial performance figures of the Apple M2 in a MacBook Air running Asahi Linux up against the AMD Ryzen Z1 Extreme and Ryzen 7 7840U SoCs on Linux.

Prior to LLVM/Clang becoming so popular within organizations and it maturing well on x86_64, AArch64, and other architectures, Open64 was once quite popular in areas now dominated by LLVM and GCC. Open64 had been popular with academic researchers, AMD even maintained their Open64 optimized compiler a decade prior to the LLVM-based AOCC, and was quite popular in the HPC space. Surprisingly there's been some recent activity on the Open64 compiler code...

Linux has supported Quick Assist Technology (QAT) devices from the start whether it be QAT PCIe adapters or QAT support found within select Atom and Xeon CPUs as well as the latest-generation Sapphire Rapids CPUs. Only now though with the upcoming Linux 6.6 kernel is it adding a heartbeat feature for determining if a QAT device becomes unresponsive so that it can be acted upon...

While the AMD EPYC 9754 "Bergamo" processor is impressive for having 128 physical Zen 4C cores, it also has Simultaneous Multi-Threading (SMT) to provide for 256 threads per socket. Meanwhile with Ampere Altra Max and AmpereOne there is no SMT and it's likely Intel's upcoming Sierra Forest will also lack SMT (Hyper Threading) given it's an E-core-only design. But that led to my curiosity over the SMT impact for Bergamo on power and performance when leveraging SMT for the 128-core flagship EPYC 9754. Today's Bergamo benchmarking is looking at SMT on and off for both 1P and 2P server configurations.

While Intel is well known -- and well regarded -- as being one of the top contributors to the Linux kernel as well as being a significant player in many other open-source projects with their countless open-source software contributions over the years, Arm is now trying to better promote their open-source support and open contributions...

In addition to the review embargo lift today for Genoa-X with our AMD EPYC 9684X benchmarks, the lift is also today on the new AMD EPYC "Bergamo" processors for offering up to 128 cores / 256 threads per socket using the new Zen 4C core. In this article is an initial look at the performance provided by the AMD EPYC 9754 128-core processors.

Last year AMD launched Milan-X as their first server processors with 3D V-Cache. The performance uplift from the 768MB of L3 cache per socket was phenomenal, but now here we are today with the next-generation successor: Genoa-X. The flagship EPYC 9684X is the new leader for HPC and AI performance as in addition to a 1.1GB L3 cache it leverages AMD's modern Zen 4 micro-architecture with AVX-512, 12 channel DDR5 memory, and other improvements found with existing EPYC 9004 series processors to easily triumph as the new best CPU for high performance computing from CFD and FEA to dozens of other scientific workloads. Here are the first benchmarks of the AMD EPYC 9684X processors.

There's a lovely new Linux kernel patch series out that's big in working on a major clean-up of the x86 APIC code (or "decrapification" as it's called in the patches) and also bringing up for discussion the idea of killing off x86 32-bit support. It's unlikely the x86 32-bit support will be removed right now, which is "just museum pieces", but as an alternative would be making it SMP-only to at least remove the uni-processor code paths...

While Intel Arc Graphics continue enjoying performance optimizations with the open-source Linux graphics driver stack, the major limitation facing Arc Graphics on Linux right now for gamers is the lack of sparse residency support that is needed for running many newer games on Linux with Intel graphics -- particularly newer Windows D3D12 titles running on Linux via Valve's Steam Play. It's been a long known limitation and will hopefully be addressed once the Intel Xe kernel driver is introduced, but at least as an interim solution there is now "fake" sparse support being implemented...
