And this is ALL anyone ever needs to know, initially.

This is not a new project. It's a project we started developing ~2 years ago. This is why I prefer not to change buildroot version. Of course I will do it in case I have no other option.

Two years and you don't have video working?? After being a kernel developer for 15???

As always, I read the documentation and also googled this issue, with no results.

Hard to believe, since mrmazda gave you links to the primer (twice), you claimed not to understand them, and they gave you a module to load...did you load it??? Did you contact the manufacturer for assistance??

Did you look at how to build the i915 module???

Hi All,

With the attached buildroot (2021.02.1) config.log file, Xorg has OpenGL support.

Thank you,
Zvika

So you loaded the i915 module you had to be told about (several times), and it worked?? Isn't that what you were told???
