This shouldn't be too surprising to long-time Phoronix readers, but Intel's performance-optimized Clear Linux operating system is yielding great performance with AMD Ryzen 7000 series "Zen 4" processors. Intel's Clear Linux has long shipped HWCAPS support and tuning for AVX-512 and the like to be able to provide optimized libraries when running on their own AVX-512 processors. But with AMD now joining the AVX-512 party -- and Zen 4's AVX-512 implementation performing great -- Intel's Clear Linux distribution is showing leading performance numbers on these new AMD desktop processors.

Intel has today sent out new compiler patches as they work to get their next-generation processors all set for the open-source GNU Compiler Collection (GCC), including the introduction of some new x86_64 instruction set extensions coming with the high core count Sierra Forest processors...

The 9P network protocol is commonly used -- such as with QEMU's 9pfs pass-through file-system -- for being able to share certain directories/files on host machines with the guest operating systems. With Linux 6.1 the 9p code has seen a nice set of optimizations that can allow for faster communication between the host and guest(s)...

Intel has published their "2022Q3" releases for their open-source Media Driver with VA-API support as well as their Intel oneVPL GPU Runtime...

The NVIDIA-VAAPI-Driver is the open-source, community-developed Video Acceleration API (VA-API) implementation that is built to make use of NVIDIA's NVDEC interface exposed by their proprietary Linux graphics driver stack. In turn this VA-API implementation is notable since it allows for NVIDIA GPU video acceleration with Firefox that targets VA-API but not the NVIDIA interfaces...

Merged for Mesa 22.3 one month ago was Rusticl as a new OpenCL implementation written in Rust. Since then Karol Herbst of Red Hat, who has led the work on this new driver front-end, has been working to get Rusticl running on more Gallium3D drivers and even atop Zink for execution with Vulkan drivers. Much of his testing/focus so far has been making use of integrated GPUs while an important patch series was merged this evening for discrete GPU fixes...

One of the leading test requests at Phoronix around my AMD Zen 4 Linux benchmarking has been some side-by-side comparisons against Microsoft Windows 11. While older, high core count AMD systems have particularly performed very well under Linux against Windows, with new hardware there is sometimes hiccups and various limitations with the at-launch support especially on the open-source Linux side. So for your viewing pleasure today are some initial AMD Ryzen 9 7950X benchmarks under Microsoft Windows 11 22H2 up against Ubuntu 22.04.1 LTS and a near-final development snapshot of the upcoming Ubuntu 22.10.

The staging changes for Linux 6.1 aren't particularly notable but of the code churn is lightening the kernel a bit by dropping the old "fwserial" driver that allows for TTY support over IEEE-1394 Firewire connections...

While LLVM Clang is increasingly being used by various developers and organizations for building the mainline Linux kernel as complementary support to the GCC compiler that has long been the predominant compiler target, Intel's ICC compiler has also been able to build the Linux kernel albeit not widely used.
