This option is selected by any driver which implements the virtio
bus, such as CONFIG_VIRTIO_MMIO, CONFIG_VIRTIO_PCI.

This option is selected if the architecture may need to enforce

select VIRTIO
help
This drivers provides support for memory mapped virtio
platform device driver. This is usually used with Qemu.
config VIRTIO_PCI
tristate "PCI driver for virtio devices"
depends on PCI && HAS_DMA
select VIRTIO
help
This driver provides support for virtio based paravirtual device
drivers over PCI. This requires that your VMM has appropriate PCI
virtio backends. Most QEMU based VMMs should support these devices
(like KVM or Xen).
