This week's round of drm-misc-next patches for staging ahead of the Linux 7.3 kernel merge window bring an exciting change for the open-source NVIDIA "Nouveau" driver.

In recent weeks there was a proposal to enable x86_64 Shadow Stack support by default with the upcoming Fedora Linux 45 release. That change has been approved now by the Fedora Engineering and Steering Committee (FESCo) but with the feature being punted off to Fedora 46 next year.

After two weeks without any Vulkan spec update, Vulkan 1.4.358 was released overnight. Besides the usual assortment of minor clarifications/fixes, Vulkan 1.4.358 introduces one new extension: VK_EXT_image_tiling_control.

Linux sound subsystem maintainer Takashi Iwai of SUSE previously warned of many sound driver fixes due to AI/LLMs and a "new normal" of patch activity as a result. While we are approaching the end of the Linux 7.2 merge window with the stable release coming up in August, the sound patches continue trending higher and this week were "far larger than wished" ahead of Linux 7.2-rc6 due out on Sunday.

Ahead of the next-generation Intel Nova Lake processors expected to begin rolling out around the start of 2027, the upcoming Linux 7.3 kernel cycle is going to begin treating Nova Lake S processors with their integrated graphics as stable.

Following AMD posting AMDGPU patches for HDMI 2.1 FRL support after the HDMI 2.1 open-source support was long blocked by the HDMI Forum, as part of working toward a complete HDMI 2.1 implementation in this AMD Linux driver it was followed by HDMI 2.1 Display Stream Compression (DSC) support. Now the latest on the AMDGPU HDMI 2.1 enabling path is enabling Auto Low-Latency Mode (ALLM) as well as HDMI Variable Rate Refresh!

It's been about a decade since seeing any new games released on the visually-impressive, Linux-friendly Unigine Engine. Unigine Corp has mostly been focusing on Unigine Engine usage for simulations and other professional applications, but coming as a surprise today is a new game being developed on their latest Unigine 2 engine technology.

The Linux Foundation hosted Open Programmable Infrastructure "OPI" announced its first coordinated release with OPI Abstraction v0.1. The work of the Open Programmable Infrastructure is hoping to standardize the data processing unit (DPU) and infrastructure processing unit (IPU) ecosystems.

With the Razer Blade 18 as the first laptop Razer's certifying for (Ubuntu) Linux use while testing it out I was predominantly using the NVIDIA R610 official driver stack. Some users were interested though in how well this laptop is working with the open-source, upstream Nouveau+NVK driver stack given Razer is marketing this high-end laptop for Linux use too. Before sending the review unit back I had run some graphics benchmarks to see how Nouveau+NVK was performing for this Razer Blade RZ09-0582 with the flagship GeForce RTX 5090 Laptop GPU.

In an interesting twist, patches this week posted to the Linux kernel mailing list are enabling AMD Zen 6 client desktop and laptop SoCs for the HSMP driver. Up to now the AMD HSMP Linux driver was just used for modern EPYC server processors while now we are seeing this HSMP driver supporting the upcoming Medusa and Olympic Ridge client platforms... Including mentions of overclocking and even noting "Ryzen Master" as the Windows-only software for overclocking and system management.

The Xen Project today released Xen 4.22 as the newest feature release of this open-source hypervisor popular for open-source virtualization in automotive systems and other embedded use-cases as well as the cloud.

A Huawei engineer posted to the Mesa mailing list today over potentially upstreaming a Vulkan driver they have developed for an in-house GPU. However, at least in current form, this new in-house GPU Vulkan driver is likely dead in the water from being upstreamed into Mesa.

The Intel Arc A-Series graphics (DG2) remains in a bit of an awkward state on Linux due to the transition period moving from the i915 kernel driver to more modern and feature capable Xe kernel driver. It's only post-Alchemist where the Intel Xe driver is officially supported and used by default while those opting for the Xe driver with the A-Series can often enjoy better performance and functionality. Except one of the caveats in using the Xe driver on Alchemist GPUs has been the lack of proper media acceleration support.

Last week Debian developers began considering a general resolution over AI large language model (LLM) usage within the Debian project. They are now up to weighing five different proposals for how to permit or block AI/LLM usage in the Debian space.

Over the past few Intel VA-API Media Driver releases we have seen preparations made for Nova Lake video acceleration. That has continued today with the Intel Media Driver and Intel oneVPL GPU Runtime releases today with their new quarterly feature releases.

The System76 and Pop!_OS developers continue quickly iterating on their Rust-based COSMIC desktop environment.

Sent out today was another week's worth of features and other code changes to the AMDGPU kernel graphics driver and AMDKFD kernel compute driver. We are nearing the cut-off of new feature material for next month's Linux 7.3 kernel but there is some nice feature work in store for this week.

Today's Steam client beta update brings some new game streaming enhancements for Linux gamers.

Intel today sent out their latest batch of kernel graphics driver updates that are ready for staging ahead of next month's Linux 7.3 merge window.

Valve has been sponsoring Collabora engineers with early phase, exploratory work for trying to bring the open-source Radeon Vulkan "RADV" driver to Microsoft Windows.
