Linux 6.16-rc4 Released With AMD Cleaner Shader For More GPUs, Bcachefs Changes

Linus Torvalds just released Linux 6.16-rc4 as we prepare to close out the first half of 2025 and hitting roughly one month until the Linux 6.16 stable release.

Linux 6.16-rc4 does incorporate the Bcachefs changes that weren't pulled last week but with Linus Torvalds now considering the removal of Bcachefs in the Linux 6.17 cycle. We'll see what happens but in any event the latest code for Bcachefs is now present in Linux

Wine-Based Hangover Project Drops QEMU In Favor Of FEX & Box64 For Emulation

Building off Friday's release of Wine 10.11 for running Windows games and applications on Linux is now Hangover 10.11 for this Wine-based software used for running Windows games/applications cross-architecture such as on AArch64/ARM64 systems.

Hangover remains focused on enabling x86 32-bit and 64-bit Windows software on AArch64 Wine thanks to emulation technology. The emulator support by Hangover has relied on QEMU, FEX, or Box

AMD Prepares Linux Driver Support For New APUs Still Relying On RDNA1 Graphics

It looks like AMD is preparing to introduce some new APUs/SoCs still relying on RDNA1-based graphics with open-source GPU driver patches posted this week extending the " Cyan Skillfish " support to some new APU devices.

A patch series was posted this week adding five additional PCI device IDs to the Cyan Skillfish family within the AMDGPU Linux kernel driver. Cyan Skillfish support was originally brought up for Linux in 2021 for Navi 1x based APUs. Now four years later there are new products being prepped

Wayback Is An Experimental X11 Compatibility Layer For X11 Desktops Using Wayland

Wayback is a new open-source project working on providing an X11 compatibility layer for running full X11 desktop environments using Wayland components with a rootful XWayland server.

Open-source developer Ariadne Conill announced the Wayback project this weekend in its currently-experimental form. Conill who is an Alpine Linux developer hopes that Wayback will be eventually suitable for running X11 session desktops atop Alpine Linux and the like with Wayland.

Linux 6.16 Extends Cleaner Shader Support To More AMD CDNA/GFX9 GPUs

The past number of months has seen work by AMD Linux driver engineers in enabling cleaner shader functionality for various generations of GPUs to help ensure user/application isolation. Being merged overnight as part of the AMDGPU "fixes" for Linux 6.16 is cleaner shader support for more AMD GFX9 / CDNA hardware, notably to benefit various Instinct accelerators with this security feature.

The AMD cleaner shader functionality helps ensure data isolation between GPU workloads. The cleaner shader will clear the Local Data Store (LDS), Vector General

RADV Ray-Tracing Lands Pointer Flags Support For RDNA3 & Newer

The RADV Vulkan driver's ray-tracing performance has improved a lot over time such as shown within yesterday's RADV vs. AMDVLK performance comparison on Strix Point . Coincidentally, merged today is yet another ray-tracing optimization to benefit RDNA3 (GFX11) and newer AMD graphics processors.

A six month old merge request by Natalie Vock was merged today for Mesa 25.2. This merge for the RADV driver enables using pointer flags on RDNA3 graphics processors and newer. Pointer flags for the

LACT 0.8 GPU Configuration & Monitoring Tool Introduces More Features

While a number of Linux desktop users have expressed disappointment over Intel and AMD not providing any GUI for their GPU driver settings and similar functionality like they do under Windows, there are a number of third-party open-source GUI programs for managing graphics driver settings. One of the most capable solutions is LACT for GPU configuration and monitoring. Out today is LACT 0.8 with more features now in place.

The LACT program provides a GUI for viewing information about your GPU, overclocking your graphics card, manipulating fan controls
