There is a newer version of this series
[PATCH v2 3/6] drm/ci: build virtual GPU driver as module
Posted by Vignesh Raman 1 year, 8 months ago 
With latest IGT, the tests tries to load the module and it
fails. So build the virtual GPU driver for virtio as module.

Why? If the test fails on module loading (if the driver is built-in)
then it's the test that needs to be fixed, not the kerenel config.

It's fine as a temporal workaround, but please include a link to the
patch posted to fix the issue.

Is it necessary to create it manually here?

This was the issue seen with IGT commit 
https://gitlab.freedesktop.org/drm/igt-gpu-tools/-/commit/7d1841317c13c19c26b6352f923b205d43742c55

https://gitlab.freedesktop.org/vigneshraman/linux/-/jobs/59037122

With the recent uprev of IGT to 
https://gitlab.freedesktop.org/drm/igt-gpu-tools/-/commit/0df7b9b97f9da0e364f5ee30fe331004b8c86b56,
this issue is not seen. So will drop this commit.
