Linux Kernel Patches Speed-Up CRC32 Performance For CPUs With "Good" AVX-512

Google engineer Eric Biggers who has been responsible for many great Linux cryptography subsystem performance optimizations in recent years has another exciting patch series. Biggers has done some great work for optimizing various functions for modern Intel/AMD CPUs especially around AVX-512 implementations and now he has another big optimization coming for the CRC32 checksum performance...

Debian 13.0 Ready To Introduce Formal RISC-V Support But Still Bound By Slow Hardware

With the Debian 13.0 release planned for 9 August, one of the notable fundamental features with this Debian "Trixie" release is now supporting RISC-V as an official CPU architecture. This is the first release where RISC-V 64-bit is officially supported by Debian Linux albeit with limited board support and the Debian RISC-V build process is handicapped by slow hardware...

Radeon Vulkan Driver's Emulated Ray-Tracing Scores A ~40% Improvement For Quake II RTX

In addition to Mesa's open-source Radeon Vulkan driver "RADV" making some nice performance improvements for modern AMD GPUs with hardware ray-tracing, the emulated ray-tracing code path in RADV for primarily older GPUs has seen some improvements merged this weekend. In fact, so significant that from one merge request is around 40% faster performance for the Quake II RTX game with the emulated RT handling...

Open-Source & Rust-Written Burn MATMUL Kernels Can Compete With NVIDIA's CUDA/cuBLAS

The open-source and Rust-based Burn deep learning framework developed by Tracel AI shared that their open-source matrix multiplication kernel performance can compete with and even outperform the NVIDIA CUDA cuBLAS performance. Plus Burn isn't limited to just NVIDIA GPUs but can work on most hardware/drivers, including a Vulkan back-end...

Arch Linux AUR Packages For Firefox & Other Browsers Removed For Containing Malware

While the Arch Linux AUR repository can be popular for fetching some packages not found in Arch Linux proper, it's important to keep in mind that AUR stands for the Arch User Repository. These user packages aren't always the best and rarely can be done with malicious intent as shown this week with an advisory over several malicious browser packages being briefly pedaled through AUR...

Intel Announces It's Shutting Down Clear Linux

The most depressing news of the week: Intel is ending their performance-optimized Clear Linux distribution. Over the past decade the Clear Linux operating system has shown what's possible with out-of-the-box performance on x86_64 hardware... Not just for Intel platforms but even showing extremely great performance results on AMD x86_64 too. But with the cost-cutting going on at Intel, Clear Linux is now being sunset...
