There is another open-source Radeon Vulkan driver (RADV) improvement to look forward to in the upcoming Mesa 26.0 release that was worked on by one of Valve's Linux graphics driver developers.

Timur Kristóf in addition to his recent work improving old AMD GCN 1.0/1.1 GPUs has finally pushed his dedicated transfer-only queue patches using the SDMA engine over the finish line. Since October 2026 was the merge request radv: Add a dedicated transfer-only

The QEMU emulator already deprecated 32-bit host CPU support while for the QEMU 11.0 release this year they could eliminate the 32-bit host support for good.

Richard Henderson sent out a set of 50 patches on Thursday to go ahead and remove the 32-bit host support. He argued the more than seven thousand lines of code savings in QEMU and the Tiny Code Generator (TCG) and is worthwhile especially with the 32-bit support already having been deprecated. He commented

Now past the end-of-year holidays, this round of Direct Rendering Manager (DRM) fixes for the in-development Linux 6.19 are a bit more meaningful following those light holiday weeks. Sent out today were the DRM fixes for Linux 6.19-rc5 that includes a fix for broken support for newer NVIDIA GPUs on the Nouveau open-source driver.

Today's round of DRM fixes for Linux 6.19-rc5 include a regression fix by David Airlie for

Valve released the SteamOS 3.7.20 beta overnight and with it they are finally building the NTSYNC kernel driver for helping accelerate Windows NT synchronization primitives.

The NTSYNC kernel driver has been in good shape for about one year now after the implementation was finished up . From user-space Wine 10.16 added NTSYNC usage support as part of the upcoming Wine 11.0 stable release due out this month. In turn Proton 11.0 will see that support when it is re-based

The latest work by Qualcomm on the RISC-V CPU architecture is sending out their first non-RFC patch series for enabling Reliability, Availability and Serviceability (RAS) support by making use of the RISC-V RERI specification. This RISC-V RAS support is useful for conveying hardware errors to users and will be especially important with future RISC-V Linux servers.

The RISC-V RERI specification is for the RAS Error-record Register Interface to standardize the logging and reporting of errors by a memory-mapped register

Canonical is making it easier for ARM64 Ubuntu users like those on the NVIDIA DGX Spark to do a bit of gaming with Steam. Canonical engineers have assembled a Steam Snap for 64-bit ARM that comes complete with the FEX emulator for running Windows/Linux x86-based games on ARM64 Linux.

Following quiet testing in recent weeks, today Canonical engineer Mitchell Augustin announced the ARM64 Steam Snap as well as an ARM64 version of the gaming-graphics "gaming-graphics

The RADV ray-tracing improvement covered earlier this week for some big performance gains for Unreal Engine 5 titles running under Linux thanks to Steam Play has been merged for Mesa 25.0.

The improvement made by Valve contractor Natalie Vock for reworking the launch ID swizzling of the RADV ray-tracing code fixes the Unreal Engine 5 illumination and reflection system. As shown in that prior article, there are big performance improvements expected for at least UE5 game titles when running on this now-merged code for the open-

For those that happen to have a Logitech MX Anywhere 3S mouse connected via Bluetooth, the upcoming Linux 6.19 kernel release is enabling HID++ support for it to enjoy high resolution scrolling and other functionality of the updated protocol.

HID++ is Logitech's addition atop of HID providing extra functionality for mice from high resolution scrolling to onboard profiles, force feedback, and other features depending upon the hardware like RGB effects. Supporting Logitech HID++ on Linux has been a headache and resorting to white

The Intel Mesa graphics drivers have supported a GPU hardware replay feature for making it easier to reproduce issues. But until now that functionality has only worked with the i915 kernel driver while for Mesa 26.0 the Intel Xe driver will also be supported.

Mesa and the i915 kernel driver have supported a hardware replay feature to make it easier to reproduce GPU hangs and other issues for expedited graphics debugging. Finally for Mesa 26.0 there will be support for the Intel Xe driver,
