Wine on Wayland: An exciting first update
Two months ago we announced a first proposal for a Wayland driver for Wine, the compatibility layer for Windows applications. Here's an update on this effort, which contains more details and instructions for building and running the Wayland driver.
New year, new kernel: Collabora's contributions to Linux 5.11
The first kernel release of 2021 brings a number of highlights contributed by Collaborans, including the new Syscall User Dispatch mechanism, and the destaging of both the H.264 stateless decoding interface and the Rockchip ISP driver.
Adding HEVC/H.265 support for NXP's i.MX 8M
Our recent efforts on the Hantro kernel driver have resulted in the addition of H.264 decoding support and multiple performance improvements. We are now introducing High Efficiency Video Coding, also known as H.265, decoding support on NXP's i.MX8 M.
Monado 21.0.0, an officially conformant OpenXR implementation!
Monado, the OpenXR runtime for Linux, is now officially conformant! In recognition of this milestone, a first major release version of the OpenXR runtime for Linux is now available, bringing with it a SteamVR driver!
Network adaptive streaming with Hwangsaeul
Hwangsaeul, or H8L, a remote surveillance streaming solution, utilizes the capability of libsrt to collect statistics from open SRT sockets and by continuously analyzing the available data tries to detect potential connectivity issues.
Trimming apitrace workload captures for better Mesa testing
Complex, real-world correctness tests and performance analysis are now possible thanks to gltrim, a new tool recently added to apitrace, designed to trim replayable traces to single, user-defined frames.
GStreamer on Windows: adding WebRTC support to a gst-build install
Earlier this week, WebRTC became an official W3C and IETF standard. GStreamer has a powerful and rapidly maturing WebRTC implementation. So, the obvious question is: how do we build this on Windows?
Implementing a performance boosting algorithm in Coccinelle
Last year, from June to September, I worked on the kernel development tool Coccinelle under Collabora. I implemented a performance boosting algorithm for one of Coccinelle's use cases. Here's a look at this work.
One weekend, two conferences
Join us as our 2021 conference schedule gets underway this weekend with the virtual editions of linux.conf.au and MiniDebConf India! Collaborans will be giving talks on recent projects including futex2, and Open Source AI video analytics with Panfrost.
Desktop OpenGL 3.1 on Mali GPUs with Panfrost
The open source Panfrost driver for Arm Mali Midgard and Bifrost GPUs now provides non-conformant OpenGL ES 3.0 on Bifrost and desktop OpenGL 3.1 on Midgard (Mali T760 and newer) and Bifrost, in time for Mesa's first release of 2021.
A Wayland driver for Wine
After several months of work, we are excited to announce a first proposal for a Wayland driver for Wine. The proposal is in the form of an RFC, in order to explore how to best move forward with the upstreaming and further development of the driver.
Kernel 5.10: Rockchip, H.264, Bifrost & more!
Even amidst the chaos and uncertainty that 2020 brought, Linux Kernel development keeps moving forward at a constant and relentless pace. Collabora remains active, developing, maintaining, documenting and testing many parts of the kernel.
Empathy first: Driving growth through people leadership
This year, the global pandemic has put a strain on us all. Motivation can become hard to maintain, worries can cloud our minds. Now more than ever, it is important to try and connect with our colleagues.
Developing Wayland Color Management and High Dynamic Range
Wayland is still lacking proper consideration for color management & support for high dynamic range (HDR) imagery. However, a group of developers has begun an effort to fix this situation. This is their story.
Linux App Summit 2020
Starting today, and running until Saturday, join us at Linux App Summit for a look at Linux graphics, PipeWire, our work with Valve, and a virtual office hour with our Engineering Manager!
A summer sprint: bringing near-native performance to Zink
This week marks two years since the OpenGL implementation on Vulkan was initially announced. Since then, and especially over the past few months, much has progressed with many new features being added and performance now close to native (95%!).
From Panfrost to production, a tale of Open Source graphics
Since our previous update on Panfrost, the open source stack for Arm's Mali Midgard and Bifrost GPUs, we've focused on taking our driver from its reverse-engineered origins on Midgard to a mature stack.
Monado update: Passing conformance, Android support & more
Monado 0.4 OpenXR runtime introduces initial support for Android and passes all of the OpenXR conformance tests with both OpenGL and Vulkan on desktop with a simulated device.

Android Leftovers
| It’s raining i.MX 8M Plus systems-on-module at Embedded World 2021
NXP introduced i.MX 8M Plus AI SoC with a built-in 2.3 TOPS neural processing unit (NPU) last year, and we’ve already covered several early announcements about i.MX 8M Plus systems-on-module (SoM) with Variscite VAR-SOM-MX8M-PLUS and DART-MX8M-PLUS, TechNexion EDM-G-IMX8M-PLUS and AXON-E-IMX8M-PLUS respectively using SO-DIMM edge connectors and board-to-board connectors, as well as SolidRun i.MX 8M Plus SoM that was announced together with the HummindBoard Mate carrier board with dual Gigabit Ethernet.
But as Embedded World 2021 Digital is taking place virtually until Friday, other companies have now made their own announcements of i.MX 8M Plus SoMs as the processor enters mass production this month, and since as far as I know, it’s pin-to-pin and software compatible with earlier i.MX 8M Nano/Mini SoCs, the update must have been easy. That means we’ve got a longish list of modules, and I have probably missed some. Supported operating systems are basically the same across companies with Linux using Builroot or the Yocto Project running on Cortex-A53 cores, and FreeRTOS on the real-time Cortex-M7 core. Some also offer Android support.
