4 This option is selected by any driver which implements the virtio
5 bus, such as CONFIG_VIRTIO_PCI, CONFIG_VIRTIO_MMIO, CONFIG_LGUEST,
6 CONFIG_RPMSG or CONFIG_S390_GUEST.

15 This drivers provides support for virtio based paravirtual device
16 drivers over PCI. This requires that your VMM has appropriate PCI
17 virtio backends. Most QEMU based VMMs should support these devices
18 (like KVM or Xen).
19
20 Currently, the ABI is not considered stable so there is no guarantee
21 that this version of the driver will work with your VMM.

23 If unsure, say M.

48 Allow virtio-mmio devices instantiation via the kernel command line
49 or module parameters. Be aware that using incorrect parameters (base
50 address in particular) can crash your system - you have been warned.
