This week, of course, saw the release of KDE MegaRelease 6 with Plasma 6.0, KDE Gear 24.02, and KDE Frameworks 6.0 in tow. Post-launch Graham characterizes Plasma 6.0 as being in good shape and the extra QA paying off. He commented, "Hopefully this should help banish those now 16-year-old painful memories of KDE 4. It's a new KDE now. Harder, better, faster, stronger!"..

The Arch Linux based CachyOS Linux distribution aims to be a "blazingly fast and customizable Linux distribution" that is aggressive with its performance optimizations. CachyOS takes to leveraging compiler optimizations like Link-Time Optimizations (LTO), the BORE scheduler, and also offering package archives compiled for x86-64-v3 and x86-64-v4 in allowing the distribution's packages to be catered toward newer Intel and AMD processors. In this article is a comparison of CachyOS packages from their main archive, the x86-64-v3 optimized packages, and then the x86-64-v4 wares that can be beneficial for modern Intel Xeon and AMD EPYC / AMD Ryzen systems.

One of the limitations of AMD's open-source Linux graphics driver has been the inability to implement HDMI 2.1+ functionality on the basis of legal requirements by the HDMI Forum. AMD engineers had been working to come up with a solution in conjunction with the HDMI Forum for being able to provide HDMI 2.1+ capabilities with their open-source Linux kernel driver, but it looks like those efforts for now have concluded and failed...

Besides the integrated RDNA3 graphics making the Ryzen 8000G series desktop APUs interesting, making the AMD Ryzen 5 8500G a fun benchmarking target besides its sub-$200 price tag is having a mix of Zen 4 and Zen 4C cores. Here are some benchmarks looking at the Zen 4 vs. Zen 4C performance and power efficiency when offlining various core combinations on the Ryzen 5 8500G desktop processor.

Back in 2022 Cloudflare announced they were ditching Nginx for an in-house, Rust-written software called Pingora. Today Cloudflare is open-sourcing the Pingora framework...

Being worked on and off for several years has been FUSE read/write passthrough support for improving the performance of File-Systems in User-Space by avoiding the daemon overhead on a per-file basis where read/write operations are forwarded by the kernel directly to the lower file-system rather than the FUSE daemon. FUSE passthrough mode has shown to be a big performance win and it looks like it could be finally mainlined come Linux 6.9...

Upstreamed for Linux 6.8 is the experimental Xe kernel graphics driver that is a modern replacement to the "i915" Direct Rendering Manager driver. The Xe kernel driver targets Tigerlake graphics and newer while it won't be until Lunar Lake / Xe2 when it aims to become the default driver for Intel iGPU/dGPU graphics. For the upcoming Linux 6.9 kernel merge window are more feature changes and fixes to this new open-source Intel kernel graphics driver...

By default the AArch64 kernel on Ubuntu and other Linux distributions tend to default to a standard 4K page size but for newer AArch64 hardware especially in the server/HPC space, there can be great benefits to using a 64K page size. As it's been a while since I last ran any 64-bit ARM 4K vs. 64K kernel page size benchmarks, while having remote access to the NVIDIA GH200 I ran a fresh comparison for looking at the performance advantages to switching over to a 64K page size kernel. These new 64K kernel numbers are shown alongside the recent AMD EPYC and Intel Xeon CPU reference benchmark results for a look at how the 4K vs. 64K page size affects the overall computing landscape.

Ahead of this week's big KDE Plasma 6.0 release, the KWinFT project forked from the KDE KWin compositor code is re-branding as Theseus' Ship...
