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...

From time to time I need to inspect a used device-tree of a running device. For instance, the used bootloader (u-boot, barebox, …) patches the the initial specified dtb and I want to see the modified one. All that is needed is an installed device-tree-compiler on the target. $ dtc -I fs -O dts /sys/firmware/devicetree/base

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....

As HTTPS is a must nowadays I decided a year a go to give it a try and got a certificate from startssl. The process at startssl took quite some time and was not that easy. With lets encrypt everything should be much easier and faster to setup – lets give it a try @ueberspace (my hoster). There is a very good (German) tutorial directly from ueberspace for the whole process....

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....
