[Bug 1475078] Re: VirtIO (and probably other modules as well) is built-in, make it modular...

 

Its a bit late for Xenial. Andy and I discussed this for the next
release. The reasons for building in some of these sub-systems no longer
exists, so we'll start modularizing in the Y series.

Bug description:
  Guys,

  Can Canonical ship Ubuntu with its Linux in a modular way?

  Honestly, don't understand why some modules are compiled as built-in,
  instead of modules, for example (NET/BLK/PCI/etc):

  ---
  ubuntu@vivid-1:~$ grep VIRTIO /boot/config-3.19.0-23-generic 
  CONFIG_NET_9P_VIRTIO=m
  CONFIG_VIRTIO_BLK=y
  CONFIG_SCSI_VIRTIO=m
  CONFIG_VIRTIO_NET=y
  CONFIG_CAIF_VIRTIO=m
  CONFIG_VIRTIO_CONSOLE=y
  CONFIG_HW_RANDOM_VIRTIO=m
  CONFIG_VIRTIO=y
  CONFIG_VIRTIO_PCI=y
  CONFIG_VIRTIO_BALLOON=y
  CONFIG_VIRTIO_MMIO=y
  CONFIG_VIRTIO_MMIO_CMDLINE_DEVICES=y
  ---

  While on Debian, it is all modular, as expected:

  ---
  debian@jessie-1:~# grep VIRTIO /boot/config-3.16.0-4-amd64 
  CONFIG_NET_9P_VIRTIO=m
  CONFIG_VIRTIO_BLK=m
  CONFIG_SCSI_VIRTIO=m
  CONFIG_VIRTIO_NET=m
  CONFIG_VIRTIO_CONSOLE=m
  CONFIG_HW_RANDOM_VIRTIO=m
  CONFIG_VIRTIO=m
  CONFIG_VIRTIO_PCI=m
  CONFIG_VIRTIO_BALLOON=m
  # CONFIG_VIRTIO_MMIO is not set
  ---

  I see no reason to load this modules in a non-virtualized
  environments.

  Thoughts!?

  Best,
  Thiago
