Hello Maira,

Regarding the second question about V3D and V3DV: in the Mesa3D CI, we
currently use downstream kernels, so we don't build the kernel for
Raspberry Pi.

BM_BOOTFS option can point to a link tarball containing an alternative kernel to use instead of downstream one.

The only drawback is that this tarball must be an already compiled kernel; it won't compile it.
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.



However, I've been thinking about the possibility of adding an override
for the kernel from an external source to our CI. This way, we can also
test with a provided kernel and override the default option of using the
downstream kernel on Raspberry Pi.

If we proceed with this, it would be sensible to include V3D* options in
our kernel builds.

I'm including Juan and Eric for their input on this topic.

The idea sounds great. Aren't we already compiling kernels for other hardware? Maybe we can include specific versions for Rpi.
