DRM format modifier support is one of the most important features we've landed in NVK in a while. Though it's not a very interesting feature to most Vulkan applications or game developers, it's very important to the Linux display pipeline. Importantly to users, this is the last piece required to support GameScope. It's also an important piece in making Zink+NVK a robust OpenGL solution.

Highlighting some of the key changes Collabora worked on with Valve to improve the system update tooling on SteamOS, including the move to Desync, making applying system updates significantly faster and more reliable.

In a recent update to NVK, Faith Ekstrand landed support in Mesa for the VK_KHR_shader_maximal_reconvergence and VK_KHR_shader_subgroup_uniform_control_flow extensions. Properly implementing these required a good bit of compiler engineering. This is the story of what went wrong and how it was fixed.

Today, we're excited to introduce DRM-CI, a groundbreaking solution that enables developers to test their graphics subsystem patches across numerous devices within the community's shared infrastructure. Released with Linux kernel 6.7, DRM-CI is a GitLab-CI pipeline that runs on the Freedesktop infrastructure. This setup allows for efficient kernel compilation and dispatches tests across multiple devices available in various community labs.

2023 was a great year for the Wayland driver for Wine. The goal was to move forward from the experimental phase and make the driver a proper upstream component. A year later, after several merge requests, many people are now already able to use the latest Wine release to enjoy some of their favorite Windows applications in a completely X11-free environment! Here's a quick look at what's to come in 2024.

By creating a real-time AI chatbot communication system using fully open source tools WhisperLive & WhisperSpeech, Collabora's engineers have addressed the unnatural delay in current bot interactions for seamless conversation.

One of the key high-level challenges of building Mesa drivers these days is figuring out how to best share code between a Vulkan driver and a Gallium driver. In the old Gallium-only world, the answer was simple: Implement Gallium and you get all the APIs for free. However, because Gallium isn't really capable of implementing Vulkan, that answer no longer works.

2024 is here, and with it comes a brand new Linux kernel release. Collabora's kernel team made a number of key contributions including a new kselftest for verifying driver probe of Devicetree-based platforms, multiple improvements to further improve support for MediaTek SoCs found in Chromebooks, and more.

As work continues on improving the kernel integration landscape on multiple fronts, this also means making better tests available for all. Working closely with the community, Collabora has now landed a new, ready-to-use, kselftest upstream in mainline Linux.

It is with the utmost excitement that we witness the release today of PipeWire 1.0, the first officially stable release of this noteworthy inter-process multimedia streaming framework after many years of development. PipeWire 1.0 now has all the features that are expected to move media streams inside a system

With the upcoming 0.5 release, WirePlumber's Lua scripts will be transformed with the new Event Dispatcher. More modular and extensible with very little redundant processing, they will look and feel completely different.

The latest mainline Linux kernel (v6.5) includes 22 patches that enable support for the AV1 uAPI and for two stateless video decoders: one for the Rockchip RK3588 and one for MT8195, a MediaTek SoC.

Today, Collabora is pleased to announce an extension of our collaboration with Arm, providing more surety and capability for Panfrost, the mainline open-source solution to support graphics acceleration on Arm's Mali GPU family. Read on for more.

Released last week, Weston 12.0 brings a number of highlights including two new backends, support for multiple scanout devices, and the addition of new protocol implementations. Here's a look at some of the changes that have landed in this new version.

NVK, an open-source Vulkan driver for NVIDIA hardware that is part of Mesa, now supports the Vulkan extension VK_KHR_multiview.

VSCode is a popular IDE (integrated development environment) from Microsoft that is highly configurable with extensions. Meson is the open source build system used by most GNOME and Freedesktop projects. It provides introspection data to integrate your project into your IDE, for tasks such as building and running your project. With the recent release of Meson 1.1.0, its VSCode extension is now fully functional & ready to use! Here's how it works.

Extracting precise 3D object information is one of the prime goals for comprehensive scene understanding. However, labeling errors are common in present open-source 3D perception datasets, which could have impactful consequences. To tackle this issue, we used Carlafox to automatically generate an error-free synthetic dataset for 3D perception.

A look at some of the Vulkan API extensions recently implemented for NVK, an open-source Vulkan driver for NVIDIA hardware in Mesa.

Rewriting bmaptool in Rust to remove Python dependencies, create statically linked binary, and allow the bmap sparse file format to be used in other Rust projects.

With more SoC support, a new V4L2 driver and a new dma-buf locking convention among its contributions, Collabora was one of the most active employers for this latest kernel development cycle. Here's a look at their contributions.
