Microsoft has made a lot of interesting developments and maneuvers over the past number of months for leveraging open-source Mesa for use by Windows Subsystem for Linux (WSL) and supporting various Khronos APIs atop Direct3D 12 for use when native drivers are lacking on Windows. This work so far has been focused on OpenGL, OpenCL, and Vulkan but Microsoft has now even implemented Direct3D 12 video API support within Mesa and leverages the VA-API state tracker support within Mesa.

Canonical continues investing a lot in ensuring a first-rate Ubuntu experience when using Microsoft's Windows Subsystem for Linux (WSL/WSL2) with Windows 10 and newer. Rather than needing to wait longer to see the fruits of that work in the next Ubuntu releases, Canonical has now made "Ubuntu Preview" available from the Microsoft Store to have a daily-updated, bleeding-edge Ubuntu experience.

With the Linux 5.18 kernel reaching stable in the next week or two there is basic support for Tesla's FSD chip.

Mesa's Radeon Vulkan driver "RADV" continues working on maturing its ray-tracing implementation after the initial code was merged last year. RADV ray-tracing is still treated as experimental and not as reliable as the proprietary NVIDIA Vulkan driver's ray-tracing support that has been around much longer, but it's getting there and at least is open-source -- unlike AMD's official AMDVLK driver that continues to not support Vulkan RT unlike their proprietary driver alternative.

Google engineer Sami Tolvanen has posted the second "request for comments" patch series on KCFI as a Control-Flow Integrity implementation better geared for Linux kernel usage than the existing CFI support.

Mesa developer Timothy Arceri of Valve's Linux graphics driver team has added a NIR varying linker for GLSL.

Linus Torvalds has released what is likely the last release candidate before officially declaring Linux 5.18 next weekend if all goes according to plan.

PAPPL as the free software project started by CUPS founder Michael Sweet after departing Apple more than two years ago, this C-based framework/library for creating CUPS Printer Applications is out with a major feature release.

An interesting Linux kernel patch series was posted this week to address inconsistent NUMA imbalancing behavior for at least some workloads. In such cases these patches address performance differences seen over the past number of Linux kernel releases going on for a while.

In addition to Linux 5.19 being the kernel set to have DG2/Alchemist graphics support in better shape with the IDs now (finally) being added and compute support being ready, this next kernel should boast improved power management handling for these "Alchemist" Arc Graphics GPUs.

The Solarflare "SFC" network driver within the Linux kernel for their high performance network adapters, owned by Xilinx and now owned by AMD, is seeing some restructuring with the next version of the Linux kernel. The intention is on shifting older network hardware to a separate kernel module/driver so improvements and new hardware support can be the focus with this main Solarflare Linux network driver.

MSM DRM driver and Freedreno creator Rob Clark continues leading the charge on open-source Qualcomm Adreno graphics/display support for Linux in this effort that started out as a reverse-engineering project years ago. This past week Rob sent in the last batch of MSM Direct Rendering Manager driver updates intended for the Linux 5.19 kernel.

With the tenth iteration of the LoongArch CPU architecture patches published on Saturday, it's looking like work is settling down and this Chinese MIPS-derived, RISC-V-inspired architecture could soon be going mainline.

For those using Keychron keyboards for being wireless, mechanical keyboards they will be better supported with the Linux 5.19 kernel.

Merged this week were some minor changes to AMD's RadeonSI Gallium3D OpenGL open-source driver around the shader selector code. One of the changes in particular though is noteworthy.

Released on Friday was systemd 251-rc3 as what should be the last planned release candidate for this first major feature update since last December.

It was another week of seeing lots of Plasma Wayland session fixes and improvements.

A feature of Thunderbolt seemingly not widely leveraged is allowing two distinct hosts/systems to be connected over a Thunderbolt cable that can then be used for tunneling arbitrary data packets using high-speed DMA rings. Should you find yourself using such a setup, starting with Linux 5.19+ it should open the door for being much faster when running on latest-generation Intel hardware for USB4/Thunderbolt.

NetworkManager 1.38 is now available for this widely-used software on the Linux desktop (and elsewhere) for managing wired and wireless network interfaces.

Earlier this week Arch Linux set the WirePlumber package to replace PipeWire-Media-Session. WirePlumber is the modern, feature-rich session manager for PipeWire and much better off than the reference PipeWire-Media-Session manager that is effectively unmaintained. But Arch Linux developers are now calling this premature and have reverted the change.
