For those with limited rack space and wanting to assemble a high-end server/workstation, the SilverStone RM32 provides a lot of opportunities in being a 3U rackmount chassis that can accommodate an E-ATX or SSI-EEB motherboard, up to a 360mm liquid cooling radiator, and up to four full-size expansion cards all within 3U height requirements. Paired with the SilverStone Extreme 1000Rz Platinum 1000W PSU, you can patch a lot into 5.25 inches.

The KVM virtualization-related changes were merged a few days ago for the ongoing Linux 7.2 kernel merge window. While there are a number of features/improvements for AMD and Intel virtualization as well as the likes of s390 and RISC-V, there aren't any new features on ARM64. The lack of ARM64 feature work this cycle is being attributed to "so many AI-fueled fixes" swamping the ARM Linux developers...

Last week the main set of sched_ext changes were merged for Linux 7.2 that included continued work on sub-scheduler support. While Linus Torvalds didn't object to any of the features being worked on for this extensible scheduler framework that relies on user-space BPF programs, he was frustrated by the layout of the new C source files and remarked, "please don't do this disgusting thing...proper hierarchical filesystems have been available since 1965."..

While the Linux 7.2 merge window doesn't wrap up until this weekend as the feature cut-off for new material, I have already begun some early benchmarks of the code currently staged for this next version of the Linux kernel. Linux 7.2 already was looking quite exciting with cache aware scheduling and other exciting new features while an unexpected surprise in my early testing this week was seeing some local network/socket performance improvements...

Over the years while working at Red Hat, Hans de Goede was known for driving many wonderful Linux laptop improvements benefiting AMD/Intel x86_64 hardware. Hans left Red Hat last year and ended up joining Qualcomm to advance their open-source/Linux support.

Released last week was Bcachefs 1.38.6 with a host of performance improvements to this out-of-tree, copy-on-write file-system. Given all the performance improvements and this being the first release since Kent Overstreet dropped the "experimental" flag on the file-system, I decided to fire up some benchmarks looking at how the Bcachefs file-system performance has changed with this new version.

Over the past half-year, Xfwl4 has been developed as a Wayland compositor for the Xfce desktop environment. Released this weekend was the first preview release of Xfwl4 in alpha form...

Google Antigravity with the Gemini 3.5 Flash model helped a Linux user sort out a situation where his laptop was taking around 36 seconds to boot the kernel, which shouldn't be the case for the high-end laptop with AMD Ryzen 9 processor and 32GB of RAM. It ended up being yet another case of device firmware issues, but now a Linux kernel patch is pending for working around the issue on the ASUS ROG Strix G16 G614 laptop while discussions are ongoing in getting the vendor to provide a proper firmware fix...

When going through the VFIO subsystem patches for the ongoing Linux 7.2 merge window, there isn't too much to get excited about for end users with these changes. But there is the first time mentioning "Blackwell-Next" enablement by NVIDIA for the Linux kernel...

Interesting feature work for VMware virtualization on Linux now being pursued by Broadcom is to support zero-copy buffer sharing between the VM(s) and host hypervisor, which would equate to an efficiency and performance win...

Linux 7.2 has finally eliminated the strncpy API from the Linux kernel. The strncpy() function for copying up to a specified number of bytes has long been deprecated and after six years of work and hundreds of patches, no more users of the strncpy interface within the Linux kernel remained that it has now been eliminated...

Merged for Linux 7.1 was ARMM64 NEON-accelerated CRC64-NVMe support for around 6x the performance out of that checksumming algorithm. The generic code had been a bottleneck in NVMe and other storage subsystem code of the Linux kernel with CRC64-NVMe being used to help verify against data corruption. Now for Linux 7.2, the NEON-accelerated code will also work for those still relying on 32-bit ARM...

The open-source world waited long enough for the GIMP 3.0 release that finally came last year with its GTK3 port and more, but for those with time on their hands this weekend and want to relive GIMP's past from long ago, GIMP 0.54 has been adapted for Flatpak to work on modern Linux desktops. What makes this version of GIMP from 1996 notable is that it was the last to use the Motif toolkit...

With KDE's Plasma 6.7 desktop having released this week, more development attention is turning to feature work toward Plasma 6.8 but there are also some fixes already accumulating for the Plasma 6.7.1 point release...

Happening back in Linux 7.1 was the "NTFS resurrection" with landing a new NTFS driver into the Linux kernel that had been years in the making and began as the former NTFS read-only kernel driver many years back before the stint of the Paragon NTFS3 driver in the Linux kernel. For Linux 7.2 that new/modern NTFS driver has seen more hardening work, some fixes, and Windows native symbolic links support...

With the code merged today to Mesa 26.2-devel, the open-source NVIDIA "NVK" Vulkan driver is capable of handling Deep Learning Super Sampling (DLSS) with modern game titles running on Linux / Steam Play...
