Separate from last week in uncovering a big performance regression on Linux 6.15 affecting workloads like Nginx and that regression getting fixed, I unfortunately discovered another heavy-hitting regression on Linux 6.15. This latest performance regression has been bisected and a possible fix is being thought through by the relevant party, but for the moment has yet to be fixed upstream and affects modern AMD processors.

Kdenlive 25.04 is out today as the newest feature release to this KDE/Qt-aligned non-linear, open-source video editing application.

The AMD-XGBE Linux network driver has seen a set of patches published for it in enabling the "new" AMD Ethernet Device codenamed Crater.

The Trinity Desktop Environment as a long ago fork of the KDE 3.5 desktop released TDE R14.1.4 on Sunday as the newest maintenance release with various bug fixes and minor feature improvements.

With the release of Ubuntu 25.04 this month I've looked at its performance on x86_64 laptops and desktop hardware to nice gains on server. That testing so far was focused on Intel and AMD systems given my abundance of x86_64 platforms. Last week I began testing Ubuntu 25.04 ARM64 on the System76 Thelio Astra powered by Ampere Altra processors. For those considering the Ubuntu 25.04 upgrade and not minding that it's not a Long Term Support (LTS) release, Ubuntu 25.04 is also allowing for greater performance on ARM hardware.

Wayland Protocols 1.44 released on Sunday and with it comes one new protocol addition.

Another change to look forward to with GNOME 49 come September is better/faster direct scanout for more applications thanks to a change that was merged to the Mutter compositor this past week.

A fresh take is being pursued around allowing the Linux kernel's out-of-memory (OOM) behavior to be customized using BPF programs.

Linux 6.15-rc4 is now available after a rather eventful week and about one month to go until the stable Linux 6.15.

Theo de Raadt announced today the release of OpenBSD 7.7, the 58th release for this BSD operating system over the past two decades.

Merged today to the widely-used FFmpeg open-source multimedia library is an APV decoder and APV bitstream muxing and demuxing capabilities. APV is the Advanced Professional Video Codec originally developed by Samsung and is a royalty-free format.

A patch currently residing within Andrew Morton's "MM" memory management branch ahead of the upcoming Linux 6.16 merge window is an addition by Red Hat for introducing deferred THP insertion to khugepaged. This deferred Transparent Huge Page (THP) insertion aims to help reduce memory waste on Linux with some workloads.

The XPG Alpha Wireless Gaming Mouse boasts a 16K DPI sensor and retails for $65~80 USD but turns out it doesn't even work properly under Linux without a pending kernel patch.

The SHA-256 code within the Linux kernel's cryptography subsystem is in the process of being refactoring so that it's available via the crypto's library API and also opening it up to support architecture-optimized implementations.

Mold 2.38 is out this weekend as the latest feature update to this open-source, high-speed linker.

Ahead of the Linux 6.16 merge window opening up in just one month, the new Zblock allocator was queued up into Andrew Morton's "MM" tree of memory management material likely destined for the next kernel merge window. Zblock is showing much potential as a compressed slab memory allocator.

Tvrtko Ursulin of Igalia has been pursuing the Fair DRM Scheduler as a "fair" scheduling policy to help with multiple applications/processes aiming to make use of the GPU concurrently. With this week's v4 patch-set to the DRM Fair Scheduler there are some big code changes but overall looking well as a nice scheduling policy for multiple apps/games/processes wanting equal access to GPU resources.

With the Linux kernel now limiting 32-bit systems to 4GB of memory even with the "HIGHMEM" Kconfig option, an issue was uncovered where if the system was still populated with more memory than addressable by 32-bit systems, the kernel would crash. With the Linux 6.15-rc4 kernel due out on Sunday, this issue will be addressed.

A new Wayland-only feature merged for GNOME 49's Mutter is support for tablet pad relative dials. These dials found on some drawing tablets now allow for relative moment under the GNOME Wayland session when paired with recent libinput and libwacom releases.

As we near the end of April, KDE developers remain quite busy working on more enhancements for the Plasma 6.4 desktop while many of them were also meeting this week in Graz, Austria for further development and planning.
