Merged last week for the Linux 6.10 kernel were all of the 64-bit ARM (ARM64 / AArch64) architecture changes. There is ACPI FACS support, the ability to easily construct FIT images, and a new command-line option for disabling 32-bit application support.
While earlier this week was looking at the AMD EPYC 4004 vs. Intel Xeon E-2488 performance for entry-level server performance, in today's benchmarking showdown is a fresh look higher up the stack at the current generation server performance out of Intel Xeon Sapphire Rapids / Emerald Rapids and AMD EPYC Genoa(X) / Bergamo / Siena with a leading-edge open-source software stack of using Ubuntu 24.04 LTS while also jumping from Linux 6.8 to Linux 6.9 for the very latest x86_64 Linux server performance.
In addition to the Linux 6.10 USB changes and char/misc with the new NTSYNC driver, Greg Kroah-Hartman on Wednesday also sent out the staging updates for Linux 6.10. There isn't much in the way of new code but some 19k lines of code removed thanks to removing an unused driver as well as a broken driver.
Similar to the GCC compiler dropping support for the Xeon Phi Knights Mill and Knights Landing accelerators a few days ago, Intel has also gone ahead and seen to the removal of Xeon Phi support for the LLVM/Clang 19 compiler.
Andrew Morton sent out more patches on Wednesday that have been pulled into the Linux 6.10 kernel. Notable from this latest round of "non-MM" updates is enabling more compiler warnings by default and getting newer AMD GPUs working on the RISC-V architecture.
GNOME Shell and Mutter had been covered by Ubuntu's GNOME MicroReleaseException "MRE" policy that allows for new point releases to ship rather easily as stable updates to existing Ubuntu Linux releases. But breaking the camel's back is GNOME 46.1 shipping explicit sync support. Due to landing a "significant new feature" into a point release, the GNOME Shell and Mutter are no longer covered by this exception.
All of the VirtIO updates are now ready for the Linux 6.10 merge window that is closing this weekend.

Over the past several years we have seen AMD Ryzen processors being used for low-cost servers, budget web hosting platforms, game servers, and more. Since the Ryzen 5000 series we have seen the likes of ASRock Rack and Supermicro putting out interesting budget-friendly Ryzen servers and that has ramped up even more with AMD Ryzen 7000 series server performance being stellar thanks to AVX-512 and other improvements making it more practical for such workloads. AMD has now solidified its positioning for entry-level servers with the introduction of the EPYC 4004 series processors. The EPYC 4004 series is derived from the Ryzen 7000 series offerings to facilitate cost conscious server options and putting the Intel Xeon E-2400 series in the crosshairs. In this review is a look at the EPYC 4004 series along with benchmarks of nearly the entire EPYC 4004 product stack compared to Intel's current top-end Xeon E-2400 series processor, the Intel Xeon E-2488 Raptor Lake.

The Fedora Engineering and Steering Committee (FESCo) has approved of the newest Fedora desktop ISO spin: Fedora Miracle.
Last week I wrote about Intel aiming to remove Xeon Phi support in GCC 15 with the products being end-of-life and deprecated in GCC 14. While some openly wondered whether the open-source community would allow it given the Xeon Phi accelerators were available to buy just a few years ago and at some very low prices going back years so some potentially finding use still out of them especially during this AI boom (and still readily available to buy used for around ~$50 USD), today the Intel Xeon Phi support was indeed removed.
It was just earlier this month that AMD Linux kernel graphics driver patches appeared for introducing a new ISP hardware block for Image Signal Processing with new AMD APUs. Already the AMDGPU ISP firmware has appeared in linux-firmware.git indicating that this "ISP" block may be coming in hardware quite soon if not already quietly found within some products.
It's not often having anything to write about on the Oracle Cluster File-System v2 (OCFS2), but with Linux 6.10 it's seeing a rather significant performance optimization.
