Xfce 4.18 released last December with some strides on the Wayland front for this lightweight GTK-based desktop environment, but more work remains before Xfce will be fully compatible with Wayland and its own robust compositor. The Xfce Wayland road-map was recently updated to reflect the latest work on this major undertaking...

Still not over the finish line for the mainline Linux kernel are the real-time "RT" patches but it continues inching toward that long-awaited goal. Out today is v6.6-rc1-rt1 as the real-time kernel patch series updated against the initial Linux 6.6 Git state...

During the Linux 6.6 merge window a pull request submitted the new "GenPD" subsystem. While the pull request did land for Linux 6.6, Linus Torvalds took issue with it -- not because of the code but over the lack of clarity on what "GenPD" is for those not domain experts in this area. To help clear things up, GenPD is being renamed to "pmdomain" to provide a bit more clarity...

Linux Mint Debian Edition 6 "LMDE 6" is now available in beta form for this desktop Linux distribution spin from the Linux Mint crew derived directly from Debian packages rather than Ubuntu...

The firmware folks at 3mdeb have released Dasharo 1.1.2 for the MSI PRO Z690-A motherboard. In case you missed it, last year 3mdeb ported Coreboot/Dasharo to select MSI desktop motherboards that are readily available in retail channels and supporting the latest Intel processors. This started with the MSI PRO Z690-A and since extended to the Z790 series. 3mdeb has released an updated Dasharo build with some new features for replacing the proprietary BIOS on these motherboards...

While Bcachefs was not merged for the Linux 6.6 cycle with one of the concerns raised by Linus Torvalds being that it hadn't been vetted via the "linux-next" staging area, that process has now begun to raise hopes of potentially seeing the new file-system driver introduced for Linux 6.7...

One of the driver additions we've been eager to see for the mainline Linux kernel that didn't pan out in time for the recently closed Linux 6.6 merge window is the Intel Xe DRM kernel graphics driver as a modern alternative to their i915 driver. The Xe driver better supports non-x86 CPU architectures, better designed and more performant around their modern integrated and discrete GPUs, and overall is able to make better design choices and improvements in being a clean sheet driver design compared to all the code that has built up in i915 over the years. But for getting the Xe driver upstream even in experimental form, first some necessary DRM scheduler patches need to be ironed out...

One of the new Linux networking features we've been looking forward to seeing in the kernel is TCP Authentication Option (TCP-AO / RFC5925) as a means of improving TCP security and authenticity. The eleventh iteration of the TCP-AO patches were posted today for the Linux kernel with it looking like work on this network addition potentially wrapping up soon...

Merged for Mesa 23.3 today is the Vulkan windowing system integration (WSI) to allow for the "PresentOptionAsyncMayTear" option that can be used to enable tearing under (X)Wayland if desiring peak performance at the cost of possible imperfect rendering...

The openSUSE Slowroll distribution is a middle-ground between the rolling-release openSUSE Tumbleweed Linux distribution and the SUSE Linux Enterprise aligned openSUSE Leap with its fixed releases. The new openSUSE Slowroll is a rolling-release-like distribution with updates "every one or two months" but with constant bug/security fixes...

Sub-NUMA Clustering with Intel Xeon processors allows for splitting up the CPU cores, cache, and memory into multiple NUMA domains for enhancing the performance of NUMA-aware applications. While SNC can help in a number of cases especially plenty of HPC and server workloads, currently it's not properly supported if making use of Resource Director Technology (RDT) on modern Intel CPUs. That is in the process of changing with new Linux kernel patches being worked on by Intel...

The Linux 6.6 merge window is over as the period by which new features and improvements are added to the kernel. Linux 6.6-rc1 is out the door as the kernel developers and testing community begin stabilizing this next major Linux kernel release. With Linux 6.6 there are many exciting feature additions but also one notable addition that once again didn't make the cut...

In addition to the EEVDF scheduler replacing the CFS code in Linux 6.6, another fundamental and interesting change with Linux 6.6 is on the workqueue (WQ) side with a rework that can benefit systems with multiple L3 caches like modern AMD chiplet-based systems...

In addition to all the open-source kernel graphics/display driver updates for Linux 6.6, merged this afternoon ahead of the Linux 6.6-rc1 tagging is merging of the DRM continuous integration (CI) code to hopefully lead to better testing of DRM subsystem/driver changes...

With Linux 6.6 the KSMBD server is no longer "experimental" while this new kernel on the SMB3 client side also brings a notable addition: the new "dir_cache_timeout" option to control the cache time for directory contents...

Earlier this year I wrote about Microsoft working on their first Vulkan extension and today it finally debuted within the Vulkan 1.3.264 spec update...

With the recently released Linux 6.5 kernel bringing AMD P-State EPP by default for modern Ryzen systems rather than the generic ACPI CPUFreq driver, running Linux 6.5 (or newer) in various workloads can lead to improved performance and/or power efficiency. Curious about the impact on the mobile side, I recently carried out some benchmarks of the ASUS ROG Ally gaming handheld with AMD Ryzen Z1 Extreme SoC from Linux 6.3, 6.4, 6.5, and 6.6 Git kernels.

In addition to the ASUS laptop improvements for Linux 6.6 with the ASUS-WMI driver, additional feature work is on the way for future kernel versions with one of those interesting additions being support for the ASUS Screenpad. Some higher-end ASUS laptops feature a secondary screen "screenpad" on the laptops and the pending ASUS-WMI driver patch will properly support it...

Since early this year AMD has been working on Linux enablement patches for Dynamic Boost Control (DBC). This is a new feature of some AMD SoCs that allow an "authenticated entity" to have greater control over certain SoC characteristics to improve the power/performance. AMD DBC was merged for Linux 6.6 just days ago while already new patches have been posted that extend the supported platforms for this Dynamic Boost Control functionality...

While we've been looking forward to Bcachefs landing and carrying out a fresh round of performance testing of Bcachefs against other file-system options, it's looking clear now that Bcachefs won't be landing for the Linux 6.6 merge window...

Merged on Thursday were a batch of KVM virtualization changes for the Linux 6.6 kernel...
