    Phoronix: Panfrost Gallium3D Picks Up Yet More Features Thanks To Collabora's Summer Internship

    Just a few days ago I wrote how the Panfrost Gallium3D driver continues making incredible progress for this community-driven, open-source graphics driver targeting Arm Bifrost/Midgard graphics. There's yet another batch of new features and improvements to talk about...

    Excellent timing, as the Pinebook Pro should be out later this year. The benchmarks should be very interesting.

      Is there some reason why this driver isn't on mesamatrix? I have just noticed virgl was added, so that's nice anyway.

        Firstly, the driver must appear on the features file:
        https://gitlab.freedesktop.org/mesa/...s/features.txt

        Secondly, I don't if the hardware supports OpenGLES 3 or higher, which seems to be the minimum level displayed on the file

        Thirdly, if all the previous requirements were fulfilled, you have to check with mesamatrix developer ( don't remember if it was Creak or someone else here in the forums) if there is any modification needed to display that information

          Hardware using the Lima driver (Mali 470 and lower) is OpenGL ES 2.0 for Utgard and 1.1 for the very first models (Mali 55/110). It'd be great to track status for lower-tier hardware, but as you mentioned, there's nothing for it on Mesa Matrix at the moment.

          The Panfrost stuff is about Midgard (T604-T880) and Bifrost (G31-G76) hardware, and all of it supports OpenGL 3.1 or higher. Midgard is getting most of the attention at the moment. Vulkan and OpenGL ES 3.2 support kicks in during the 3rd generation of Midgard (Q3 2013), but is present for all of Bifrost. It's rather suitable for tracking, and since they're mainlining things, I think it'll get added at some point.

          The internship is about stabilizing the OpenGL [ES] 2.0 support, so it might be a bit premature at this point. I'd still love to see it up there. It'd be nice if Mesa Matrix could showcase the early wins as well as the late-game wins.

          EDIT: left out the "ES" in the internship details.

            Nice to know that a open-Source driver is closer for MidGard/Bifrost Graphics Hardware..
            Is Lima already merged for Utgard Hardware, and working?
