  • Etnaviv Gallium3D Picks Up A NIR Compiler

    Open-source developer Jonathan Marek merged the support yesterday that allows for a NIR-based compiler as an alternative to its own homegrown compiler infrastructure for dealing with OpenGL shaders. NIR is the "new" Mesa common IR used by the likes of Intel's OpenGL/Vulkan drivers, RADV, optionally for RadeonSI, and other drivers like Freedreno and V3D. By leveraging NIR, this should help in their OpenGL (ES) advancement and potential for squeezing more performance optimizations as the Etnaviv reverse-engineered driver continues maturing.

  • ROCK Pi and an easy place: Panfrost & Wayland on a Rockchip board

    With the release of the 5.2 Linux kernel, you might have noticed that Collabora has done a lot of work with Rockchip's RK3399 platform, more specifically with the ROCK Pi 4 single-board computer.

    Our ongoing work on the reverse-engineered Panfrost OpenGL ES driver for Arm Mali GPUs turns the RK3399 SoC into a very attractive platform to try out Wayland on ARM devices, especially since it's such a versatile platform that is both affordable to buy and is available in multiple form factors, including system-on-module (SoM) and single-board computer (SBC).

  • Intel's Iris Gallium3D Driver Gets A 1 Line Patch To Bump The Performance By ~1%

    Intel's Iris Gallium3D driver as their new OpenGL Linux driver aiming to be the default Mesa driver by year's end continues seeing more performance optimizations now that the fundamentals are in place. The latest optimization is a one line tweak yielding around one percent higher performance across the board.

  • ROCK Pi 4 Is Becoming A Good Arm SBC With Panfrost Graphics & Wayland Support

    At $39 to $66 USD depending upon model, the ROCK Pi 4 is evolving to offer nice open-source support down to the Arm Mali graphics thanks to the Panfrost Mesa driver and also works nicely with Wayland.

    The ROCK Pi 4 single-board computer is what Collabora developers have been using lately for a lot of their work on the likes of the Panfrost Gallium3D driver and other Rockchip platform efforts. The ROCK Pi 4 makes use of Rockchip's RK3399 SoC (Mali T860 MP4 graphics, dual-core Cortex-A72 + quad-core Cortex-A53) and is paired with LPDDR4 and other typical components of modern ARM SBCs.
