Other than that, I found that the kernels in the PPA does not have some
module drivers. As for example, I am looking for the vfio drivers, that is
generated by CONFIG_VFIO=m

These drivers are usually generated by linux-image-extra, and this image
seems not to be available in the mainline build (kernel-ppa)[1]. How do I
install these extra modules if I am using a mainline kernel?

Thank you,
