It would be great if you could fill in missing kernel config options for 
machines you use for V3D(V) in
the `kernel/configs/mesa*.config` within the `gfx-ci/Linux repository 
(the config files here origin from there).

If the compiled kernel will work on RPis, then the next step would be 
adding kernel format
and DTB names to the `src/broadcom/ci/gitlab-ci.yml` in the Mesa 
repository so that you can use my Mesa draft MR [1]
to quickly test if your jobs would work with the mainline kernel and any 
other board that won't break due to your changes.

When this integration is done ‒ it's easy to run drm-ci testing on these 
machines.
