With the recent stable releases of LLVM's Clang 16 and GCC 13 compilers there is now initial AMD Zen 4 "znver4" support in these open-source compilers. Curious about the performance difference between these two compilers on the very newest AMD 4th Gen EPYC "Genoa" server processors, I ran some LLVM Clang 16.0 and GCC 13.1 benchmarks on the flagship EPYC 9654 2P Linux server.

Last week XFS users began encountering metadata corruption on the latest Linux 6.3 point releases. Following kernel developers and those testing the kernels on affected hardware over the US holiday weekend, it's believed the issue has been tracked down to one missing patch that is a one line of code being deleted...
One of the new features of Intel Xeon Scalable 4th Gen "Sapphire Rapids" server processors is support for Trust Domain Extensions (TDX) but for this generation is only being activated for CPUs going to select cloud providers. Intel TDX allows better isolating virtual machines from the VMM/hypervisor and other non-TD software on the platform. This limited roll-out of Intel TDX has worked out okay with the Linux support for this security feature still being in flux. Sent out today was the 14th spin of the 113 patches needed for getting KVM TDX support wired up within the Linux kernel...
While GCC 13 saw its first stable release several weeks back, for those taking their time in moving to major new compiler releases and still relying on the two-year-old GCC 11 series, out today is the GCC 11.4 point release...
A few days ago I wrote about a Linux kernel patch being prepared for fixing Intel hybrid CPU SMP/HT topology reporting due to the way the Linux kernel was currently counting the number of Hyper Threading siblings for each core. Fortunately, that fix which is apparently becomes more pressing for upcoming Meteor Lake processors, has now been picked up in time for today's Linux 6.4-rc4 release and is set for back-porting to stable kernel series...

Announced on Thursday was the Ubuntu High Performance Computing (HPC) team to promote Ubuntu Linux for running AI/ML, energy, bioinformatics, meteorology, and other workloads on Ubuntu Linux...
A fix is on its way to the mainline Linux 6.4 kernel and also marked for back-porting to existing stable kernel series to fix x86 topology reporting for Intel Hybrid systems. The topology bug within the kernel becomes more pronounced for Meteor Lake laptops where currently internal Intel test laptops can report the systems having 11 CPU sockets rather than the proper number of cores all contained within one CPU socket...
Queued up ahead of the Linux 6.5 cycle kicking off in about one month is a new Linux x86 optimization patch for further tuning csum_partial, the function used within the kernel for calculating 32-bit checksums on blocks of data. Much lower latency and higher throughput can be observed with the newly-optimized csum_partial on the latest Intel/AMD processors...

Sent out last week by Alexandre Bailon with Bay Libre is the AI Processing Unit "APU" Direct Rendering Manager driver to interface between CPUs and AI Processing Units. The hope is this APU driver could be re-used by various hardware drivers while the initial focus is on bringing up the AI capabilities of the MediaTek MT8183 SoC...
Going back to 2020 has been work by Intel's open-source engineers on implementing Key Locker support for Linux. Intel Key Locker allows for encrypting/decrypting data with an AES key without having access to the raw/actual key. AES keys are converted into handles with Intel Key Locker that can then be used for carrying out encryption/decryption on that system until revoked or system state changes. Intel engineers on Wednesday posted their seventh iteration of the patches for supporting Key Locker on Linux...
In addition to Microsoft's Build 2023 conference this week where they announced expanded archive/compression format support, Windows Terminal improvements, more AI tech, and other initiatives, they also happened to release CBL-Mariner 2.0.20230518 as the newest version of their in-house Linux distribution...
Since the early bits of Wine Wayland support were merged back in March for building up a native Wayland display driver, Alexandros Frantzis has continued submitting more of the code for review and upstreaming. Wednesday marked the third chunk of Wine Wayland code to be merged...
Among Intel's dozens of terrific open-source components -- including the many components making up their oneAPI software suite -- is Open Image Denoise. Open Image Denoise for years has been a terrific, high-performance denoising library for ray-tracing use The software has long been CPU-based while being highly performant thanks to leveraging modern instruction set extensions. Today though Open Image Denoise 2.0 is released and brings GPU acceleration across Intel, AMD, and NVIDIA graphics processors...
The Intel IPU6 web camera tech found in Alder Lake laptops and newer has unfortunately no upstream Linux driver yet and has resulted in kernel developers avoiding these laptops where web camera support is needed. Intel maintains an out-of-tree IPU6 Linux driver while they have been making progress toward ultimately getting it upstreamed. To ease the situation for Fedora Linux users, an experimental IPU6 software stack has now been added to the RPM Fusion repository...
For those that have been interested in the Radeon RX 7900 series for the great open-source driver support on Linux but have been wanting a cheaper graphics card and perhaps are a 1080p gamer, today's launch of the Radeon RX 7600 will surely be of interest to you. The Radeon RX 7600 is a nice lower-end graphics card for 1080p gamers and has upstream open-source Linux support already -- including the ability to run out-of-the-box already on Ubuntu 23.04 and other newer distributions. Here is my Linux performance review of the AMD Radeon RX 7600.

The AMD k10temp Linux driver is used for CPU temperature reporting with all modern AMD Ryzen/EPYC processors plus going back all the way to many earlier FX / Athlon / Sempron / Opteron / Phenom CPUs starting with the Family 10h line-up. While this driver has been in the Linux kernel for years, it's carried a limitation until now that it can't handle reporting negative temperatures. That is changing thanks to new patches from AMD...
