In addition to the big performance uplift from AVX-512, up to 96 cores per socket, and other Zen 4 architectural improvements, also empowering the EPYC 9004 "Genoa" processors is the support for up to 12 channels of DDR5-4800 memory. In this article is a wide assortment of benchmarks looking at the AMD EPYC 9654 performance across varying numbers of populated DDR5 memory channels.

Following the recent discussions around Fedora planning to disable byte swapped clients support for the X.Org Server in order to close another "large attack surface" with the aging X11 server codebase, the upstream X.Org Server has now dropped this support by default...

Linspire as the Linux distribution whose roots go back two decades ago to when it originally started out as "Lindows" is preparing a new major release. The current incarnation of Linspire though started five years ago when PC/OpenSystems acquired the Linspire and Freespire rights from Xandros. Linspire claims to be "the easiest desktop Linux" and are looking to improve things further with their v12 release...

While MGLRU is a nice performance win for the Linux kernel now available when enabling it for v6.1+ kernel builds, during my testing I did encounter a regression around the SVT-AV1 video encode performance at least and a fix is working its way toward mainline...

Over the past few years it's become possible to compile the mainline Linux kernel with LLVM/Clang compared to the long-standing dependence on using the GCC compiler. While it's been possible for 3+ years to use the mainline Linux kernel and mainline Clang for building a working x86_64 and AArch64 kernel, the process and support continues to mature...

After enjoying a two month holiday, Valve-funded Mike Blumenkrantz is back to working on Mesa's Zink code that implements OpenGL (and via Rusticl even OpenCL) atop the Vulkan API. Zink has shown it can be quite competitive in its OpenGL performance atop Vulkan compared to dedicated OpenGL drivers and in 2023 should be maturing into even better shape...

GNOME's Mutter now allows disabling XWayland support at build-time if so desired. This is part of the broader GNOME effort for making X11 support optional and ultimately allowing for a modern Wayland-only environment if so desired and without carrying legacy X11 cruft...

While back in 2018 when the C-SKY architecture was merged to the Linux kernel it was talked about possibly being the last new CPU arch/port to be mainlined given the growing success of RISC-V even back then, it looks like that upstream kernel developer belief might not hold true. France-based Kalray that focuses on high-performance, data-centric computing from cloud to edge posted their initial Linux kernel patches today for their "KVX" kernel port to get the kernel running on their MPPA3-80 "Coolidge" DPU SoC with the KV3-1 CPU architecture...

The past several months saw much discussion over a proposal to add "-fno-omit-frame-pointer" as a default compiler flag to Fedora Linux that would improve profiling/debugging but with possible performance implications that can vary based on the application/workload. While just over one month ago FESCo rejected that change, they re-voted today and decided after all to allow this change to happen but to ensure that packages can easily opt-out if they find performance regressions. By Fedora 40 they will also re-visit the matter to determine if the benefits and performance costs are justified...

The D1 is Allwinner's first SoC based on a RISC-V core design. While the Allwinner D1 isn't powerful at all, it's appearance in low-cost boards, RISC-V based design, and the Allwinner development community has made this an attractive entry-level RISC-V target. While various Linux distributions are already supporting D1-based boards, the mainline support for the D1/D1s platform looks like it will finally be merged in 2023...
