The Ubuntu Mainline Kernel PPA for years has been a great feature for Ubuntu users to be able to easily fetch and run the newest upstream kernel whether it's the latest stable kernel version, one of the weekly release candidates, or even the very leading-edge daily Git kernel builds. Sadly for months now this service has been out of order...

Initially merged back for the Linux 6.13 kernel was EXECMEM_ROX support for module text on x86_64 systems. With this caching of large ROX pages it can help with lowering TLB instruction pressure and enhancing performance. But this EXECMEM_ROX support that was contributed by a Microsoft engineer ended up being reverted in the final days of Linux 6.13. The revert came due to bugs and not having any Linux x86 maintainers signing off on the code. This code has been getting into shape for trying again with the mainline kernel...

Red Hat's Kpatch, Oracle's Ksplice, and SUSE's kGraft are the most well known solutions currently for Linux kernel live-patching primarily for applying security patches to running Linux servers.

Red Hat engineers have been working on Nova as an open-source driver successor to the Nouveau driver for upstream NVIDIA GPU support within the Linux kernel that can be used with the Mesa OpenGL/Vulkan drivers. Unlike the prior larger RFC patch series, sent out to the Linux kernel mailing list today were some small patches for introducing "NOVA-Core" that would serve as the initial base for this modern NVIDIA Linux kernel DRM driver. Over time and succeeding kernel releases, the NOVA code would be built up until ultimately becoming a usable state for end-users...

Back in October following the launch of the EPYC 9005 "Turin" processors I ran an AVX-512 performance comparison for the EPYC 9755 with 512-bit data path vs. 256-bit data path vs. AVX-512 disabled. That was interesting for showing the benefits of Zen 5's full 512-bit data path support compared to the "double pumped" approach with Zen 4 or optionally used via a BIOS option on Zen 5. AVX-512 continues to prove to be very performant and power efficient with AMD Zen 5 processors unlike with the early generations of AVX-512 on Intel processors. Here is a fresh look at the AVX-512 performance on a Supermicro server with an AMD EPYC 9655 processor.

Over the past week I have published a number of GeForce RTX 5090 Linux compute benchmarks as well as the GeForce RTX 5080 on Linux. With that early NVIDIA R570 Linux driver build as part of the CUDA 12.8 package I was asked to wait on Linux gaming benchmarks until the proper RTX 50 Linux driver is released. Well, it was released this morning with the NVIDIA 570.86.16 Linux beta availability and have in turn been pushing the GeForce RTX 5080 and RTX 5090 through a number of Linux gaming/graphics benchmarks.

Last week saw the big set of Bcachefs updates merged for the Linux 6.14 kernel that included the last anticipated big on-disk format change as well as scalability improvements.
