One of the limitations of AMD's open-source Linux graphics driver has been the inability to implement HDMI 2.1+ functionality on the basis of legal requirements by the HDMI Forum. AMD engineers had been working to come up with a solution in conjunction with the HDMI Forum for being able to provide HDMI 2.1+ capabilities with their open-source Linux kernel driver, but it looks like those efforts for now have concluded and failed.

With Valve's release today of the Steam Audio SDK 4.5.2 they have made the software development kit fully open-source under an Apache 2.0 license.
There are still no signs of a new X.Org Server feature release coming in the near-term with most of the major stakeholders divesting from the xorg-server besides the XWayland portion of the code-base. But for those interested in the past few days there have been some NetBSD/OpenBSD build fixes to the X.Org Server as well as clearing out some remnants of old compiler support.
Back in 2022 Cloudflare announced they were ditching Nginx for an in-house, Rust-written software called Pingora. Today Cloudflare is open-sourcing the Pingora framework.
Nearly one year ago Intel published the X86S specification (formerly stylized as "X86-S") for simplifying the Intel architecture by removing support for 16-bit and 32-bit operating systems. X86S is a big step forward with dropping legacy mode, 5-level paging improvements, and other modernization improvements for x86_64. With the Linux 6.9 kernel more x86S bits are in place for this ongoing effort.
Merged two years ago with Linux 5.15 with the "NTFS3" driver developed by Paragon Software with working read-write support and other improvements for supporting Microsoft's NTFS file-system driver. This driver was a big improvement over the original NTFS read-only driver found in the mainline kernel and faster than using the NTFS-3G FUSE file-system driver. Now with enough time having passed and the NTFS3 driver working out well, the older NTFS driver is set for removal.
George Hotz with Tiny Corp that is working on Tinygrad and TinyBox for interesting developments in the open-source AI space has previously called out AMD over ROCm issues. Yesterday yielded new tweets by "the tiny corp" over AI training runs crashing with MES errors and then called for AMD open-sourcing the firmware to which AMD CEO Lisa Su has responded.
Mesa 24.1 Git has landed the initial infrastructure for allowing drivers to choose to using Zink instead for OpenGL via this OpenGL-on-Vulkan implementation. The motivating factor for this latest Mesa work is for using Zink atop the NVK Vulkan driver for newer NVIDIA GPUs.
Fedora Workstation has long defaulted to using GNOME's Wayland session by default, but it has continued to install the GNOME X.Org session for fallback purposes or those opting to use it instead. But for the Fedora Workstation 41 release later in the year, there is a newly-approved plan to no longer have that GNOME X.Org session installed by default.
The EFI updates were merged today for the ongoing Linux 6.9 merge window. This cycle the EFI kernel code is seeing enhancements for confidential computing as well as for satisfy Microsoft's requirements for getting them to sign the x86 shim loader again for UEFI Secure Boot handling.
The AMDGPU Linux driver up until the recent Linux 6.7 kernel release has let you lower the power limit of your graphics card with, well, no limits... This has allowed AMD Radeon Linux users to limit their GPU power draw when desiring for power/efficiency reasons. But since Linux 6.7 they've begun enforcing a lower-power limit set by the respective graphics card BIOS. Users petitioned to have this change reverted but in the name of safety this lower-limit enforcement will stand.
Depending upon how Linus Torvalds is feeling today, Linux 6.8 could debut today as stable and in turn mark the opening of the Linux 6.9 merge window... Otherwise it will be punted off by one week. In any event, there's a lot of interesting work queuing for Linux 6.9 as shared in today's preview.
Ant Group and Alibaba have proposed PVM, the Pagetable Virtual Machine, as a new virtualization framework built upon the Kernel-based Virtual Machine (KVM) hypervisor. PVM does not require hardware-assisted virtualization while working with KVM-enabled software like Kata Containers.
For years Wine developers have been after a better synchronization API for the Linux kernel to better match the semantics of Microsoft Windows. Posted back in January was a request for comments on an "NTSYNC" Linux kernel driver to implement Windows NT synchronization primitives for the Linux kernel. At the start of the month a post-RFC version was posted of this open-source driver and today the latest iteration of that work has been published to the kernel mailing list.
It's hard to believe we are already just down to a few days left before the release of Plasma 6.0 next week alongside KDE Frameworks 6 and KDE Gear apps ported over to the Qt6 toolkit. KDE Plasma 6.0 is pretty much primed for release while already fixes are beginning for Plasma 6.0.1 as well as early feature work underway for Plasma 6.1.
The GNOME Prompt terminal emulator in-development by Christian Hergert with a focus on GPU-acceleration and being a very speedy and beautiful terminal option has been renamed to Ptyxis.
The lightweight LXQt desktop environment is fully ready to take on the Wayland world.
Daniel Almeida with Collabora has posted a rewritten of the VP9 codec library code within the Linux kernel's Video 4 Linux 2 (V4L2) subsystem. In using Rust rather than the existing C code, this should yield better memory safety and better fend off potential issues within the existing code.
A "request for comments" patch series was posted on Monday for a new dynamic kernel stacks feature for Linux. Early testing has shown the potential for significant memory savings.
KDE developer Nate Graham is out with his weekly development summary outlining the interesting feature work and bug fixes to land in the KDE space. Being fresh off the recent Plasma 6.0 release, a lot of bug reports are still coming in while developers are already busy tackling new features for Plasma 6.1.
Microsoft announced today they will be winding down their support for Windows Subsystem for Android (WSA), which is similar to Windows Subsystem for Linux (WSL) but was designed to run Android apps from the Amazon Appstore atop Windows 11.
GIMP 2.99.18 was released today as the last planned development version prior in the long road to GIMP 3.0 that has been a decade in the making for this free software Adobe Photoshop alternative.
Linux 6.8 could debut as stable as soon as tomorrow if all goes well... Linus Torvalds last week was unsure whether an extra release candidate would be needed after the quiet 6.8-rc7 release. This week's seen a continued flow of fixes land, so we'll see what Linus decides on Sunday but in any event there are already a number of early 6.9 pull requests.
Since the Bcachefs file-system was upstreamed in the Linux 6.7 kernel it's been humming along fairy well. But today the Bcachefs feature updates were sent in for the Linux 6.9 merge window and Linus Torvalds isn't happy about some of the proposed code.
Back in 2020 AMD rolled out a video mode optimization for FreeSync on Linux, continued being revised in 2021, FreeSync Video mode then attempted by default in 2022 but then was reverted and then only last year FreeSync Video enabled by default. But now come Linux 6.9, the feature appears to be effectively retired.
