The BeOS-inspired Haiku open-source operating system project has published their June 2026 status report. In the past month the developers merged their NVMM VM monitor support, hardware driver improvements, and progressed toward the upcoming Haiku sixth beta release.

Going back to Google Summer of Code 2024 was work on porting the NetBSD Virtual Machine Monitor "NVMM" over to Haiku for hardware-accelerated virtualization support with QEMU. That NVMM port has finally been merged to upstream Haiku. But it's known

A month ago there was a change proposal raised for offering a "light" version of the GRUB2 bootloader for use in confidential computing environments. While there were some differing views on the matter for this alternative, stripped-down GRUB package as opposed to just using other bootloaders like systemd-boot, ultimately, the proposal is now approved.

The Fedora Engineering and Steering Committee (FESCo) has now approved this Fedora 45 change proposal for having a light, alternative version of GRUB2 focused on confidential computing needs.

Overnight the Weston 16.0 release occurred as the latest milestone for this reference Wayland compositor.

Weston 16.0 delivers the latest improvements to Wayland's high dynamic range (HDR) display support and color management handling. Weston's DRM back-end now supports the "color format" DRM connector property, there is a grayscale output color effect added to Weston, color pipelines support is added to the DRM back-end, various color transform additions, and a number of other HDR/color related

For those having Linux systems with multiple swap devices, such as for swap tiering or layered swap handling, a set of patches posted today for the Linux kernel are looking to improve the situation.

While most Phoronix readers are likely not leveraging multiple swap devices, for those with more complex Linux server deployments there is a new and interesting patch series out of Tencent. Kairui Song has been leading the effort to better distribute I/O to multiple swap devices and address multiple outstanding design issues in the process with the Linux swap handling

Alfonso Siciliano, who has been one of the FreeBSD developers leading the effort on adding a KDE-based desktop option to the FreeBSD installer , provided an update on recent work around adding integrating this desktop option.

Following integration work already accomplished in May for being able to provide automatic GPU detection for Intel and AMD graphics hardware based on pciconf and fwget data, the attention more recently has turned to properly handling the NVIDIA FreeBSD driver support. In particular, due to the official NVIDIA FreeBSD drivers having different driver branches from NVIDIA for

GNOME developers working on GNOME OS have received funding from Germany's Prototype Fund to work on creating the GNOME OS "Developer Tool Suite" or also tentatively called their "Test Center" to help in testing experimental applications/libraries in a modern Linux computing world with systemd-sysext, Buildstream, and other newer tech.

In the belated issue of This Week in GNOME , this GNOME OS "Test Center" is described as being akin to Apple TestFlight or the old Mozilla Labs for testing experimental/development software in image

Stemming from looking at a proposed Linux kernel patch to alter the Linux kernel's system call number handling, veteran Linux kernel developer Thomas Gleixner went down a rabbit hole of the kernel's system call entry handling to make a number of clean-ups and improvements to the code. That rework to the system call entry handling is now expected to land for the Linux 7.3 kernel cycle.

When going through the system call entry handling code for Linux, he realized some CPU architectures supported by the Linux kernel weren

While the Raspberry Pi 5 is already over two and a half years old, one of the missing elements of its support from the mainline Linux kernel has been the IOMMU driver. We are now seeing Raspberry Pi's downstream IOMMU driver being adapted for mainline with hopes of getting it into the upstream kernel.

Open-source developer Daniel Drake has been working on the Broadcom BCM2712 IOMMU driver support as used by the Raspberry Pi. The driver is adapted from Raspberry Pi's downstream driver but with various
