The Year 2023 in Retrospect

Holidays are here and I have time to look back at 2023. For six months I have been working for Igalia and what should I say? I ❤️ it! This was the best decision to leave my comfort zone of a normal 9-5 job. I am so proud to work on open source GPU drivers and I am able to spend much of my work time on etnaviv. Driver maintenance Before adding any new feature I thought it would be great idea to improve the current state of etnaviv’s gallium driver....

You might be familiar with mesamatrix - a nice site to track the state of all GPU drivers provided by Mesa. Ohh.. did I say all? Let’s have a closer look: This page is a graphical representation of the text file docs/features.txt from the Mesa repository. So wouldn’t it be sick to get etnaviv mentioned in docs/features.txt and onto the matrix? First mesamatrix needs to know/support etnaviv. This seems to be quite simple as there is already a pull request to add a bunch of embedded GPU drivers: Add VC4,VC5 and Vivante GPUs...

etnaviv officially landed

After years of hard work the etnaviv team reached an other very important milestone. The gallium driver and the renderonly library got pushed into mesa’s git repository and will be released with mesa 17.0 - yeah! This does not mean we are done with development at all. There are many interesting topics to work on and some of them like better support for newer IP cores or a reworked GLSL compiler should see the light of day during the next months....

etnaviv: kmscube

Last Friday I got kmscube successfully running with mesa and the new etnaviv DRM kernel driver. At this time I got it not really pixel perfect and I spend some nights to get it fixed. It turns out that I need a small mesa hack to get the rendering correct. You may ask why did it so long to get it working? Let me explain it to you. The Vivnate GPU is a so called render-only GPU which does not have any kind of scanout logic in it....

Mesa meets GC2000

Here is the first result of running mesatest_gles on mesa&etna: Following tests are showing good visual results compared to swrast: Hello_Triangle/CH02_HelloTriangle Simple_VertexShader/CH08_SimpleVertexShader CubeVBO/cube_vbo ParticleSystem/CH13_ParticleSystem Viewports/viewports All other are visual corrupted or segfault. So there is still some work done to get all demos up and running.
