This will allow us to stop compiling e.g. the virtio-blk module into
the kernel, because it will be loaded by the initramfs.
This introduces some duplication between the rootfs and initramfs's
Makefiles. I don't think it's worth the effort at the moment to try
to reduce that, because it would come at the expense of additional
complexity in the Makefiles. We can revisit this later if we want to.

These drivers should be loaded by the initramfs if required — most
Spectrum installs won't need the virtio drivers on the host, and
overriding the kernel means more stuff we can't reuse from
cache.nixos.org.
We'll probably want to build in the driver for whatever filesystem we
end up using for the root file system eventually, since it will always
be required, but that should be done as part of a more systematic
effort to optimise our kernel configuration.

Hi,
This patchset introduces errors in the default qemu
configuration of spectrum, where it is possible to see in the
console log attempts to load broken aliases like:
modprobe: FATAL: Module acpi:PNP0C0F: not found in directory
/lib/modules/5.18.0
As well as valid modules load failures like:
modprobe: ERROR: could not insert 'vfio_pci': Invalid argument
The full boot log is attached for further perusal.
Best regards.
José.

This is pretty much expected. The only job of the initramfs is to get
the root filesystem mounted, so most kernel modules are not included in
it to keep the size down. It just contains modules related to block
devices, dm-verity, ext4, etc. If a we try to load a driver in
initramfs, and it isn't available, that's fine, because when we get to
the root filesystem, we run mdevd-coldplug again, and the module will be
loaded at that point.
The reason this didn't happen before when testing Spectrum in a VM is
that since all the drivers we needed were built in to the kernel, the
the block device nodes would be available before userspace even started,
meaning that the initramfs simply wouldn't have any time to try and fail
loading any other drivers before the rootfs was ready. On hardware,
where the appropriate drivers wouldn't have been built in, I assume
these messages would already have been normal without this change,
although I didn't test.

I wasn't able to reproduce this, with this series applied on top of
commit c0b9dff8653b59f5d2a24bb539cba6c91d3f7506,
Nixpkgs commit 4d05083dd894b73941e2e7d3b4f428b0ce1c7007, running
Spectrum with `make run' in the host/rootfs directory. I started netvm
and verified that the QEMU ethernet device was successfully passed
through as well, so vfio-pci was definitely working.
Does that differ to the versions you were using to test? If so, could
you try with those versions and let me know if that works for you?

Yes, I was living in b01594b2c089ce2434dacddccf9a285af7334d24,
right version on nixpkgs. Rebasing on upstream main solved the issue.
Thanks!

Awesome! If it's now working for you, want to send me some Tested-by:
lines for the patches you've tested, so they can be recorded in the
commit log? (Just reply to the patches you've tested with "Tested-by:
José Pekkarinen <jose.pekkarinen@unikie.com>" on a line on its own, and
then it'll be automatically picked up when I apply the patches.)
