Linus Torvalds can be known for his hardware commentary at times like hoping AVX-512 "dies a painful death", Intel's "bad policies" around ECC memory, and giving NVIDIA the finger. The latest colorful commentary by the Linux creator is around Intel's new Linear Address Masking (LAM) feature that aimed to land in Linux 6.2 but is now delayed until the code can be reworked...

After recently getting H.264 and H.265 video decode working for the Mesa RADV Vulkan driver with the current Vulkan Video extensions, David Airlie of Red Hat resumed his prior work on enabling the Vulkan Video extensions for the open-source Intel "ANV" driver too...

As written about last month, Sony has been working on adding DualShock 4 controller support to their newer PlayStation HID driver in Linux. The DualShock 4 controller has long been supported under the older "hid-sony" driver but now with Linux 6.2 the support can also be found under "hid-playstation"...

Introduced in early 2021 with now prior-generation AMD EPYC 7003 "Milan" processors was SEV-SNP as the "Secure Nested Paging" addition to their Secure Encrypted Virtualization technology. While this year saw the initial SEV-SNP support was finally merged to the mainline Linux kernel, the hypervisor portion remain outstanding and have taken a step back as the AMD engineers overhauled their implementation...

Last month when AMD launched the EPYC 9004 "Genoa" series they also published AOCC 4.0 as the newest version of the AMD Optimizing C/C++ Compiler derived from LLVM/Clang and tailored to their latest Zen microarchitecture. At the time I ran some AOCC 4.0 benchmarks on the Ryzen 7000 series and compared it to GCC and Clang. Since then I've had the time on my Genoa test rig to look at how well AOCC 4.0 is performing and in this article are some benchmarks with the EPYC 9374F processors between GCC and AOCC 4.0.

Well known Mesa developer Marek Olšák has for years meticulously optimized the RadeonSI driver and before that R600g and R300g where he got his start as a student developer. Besides ensuring the AMD Radeon OpenGL performance is in great shape for Linux gaming, he's also spent much time more recently in focusing on workstation OpenGL performance and with that the common SPECViewPerf benchmark. This week he landed another set of patches providing around a 7.5% improvement for one of the SPECViewPerf tests...

The x86/microcode changes that were merged this week into the Linux 6.2 kernel address prior shortcomings with the Intel In-Field Scan (IFS) driver so it's now deemed ready to help in spotting out faulty silicon across a fleet of systems in production or prior to commissioning new hardware...
