config VIRTIO

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

config VIRTIO_PCI

tristate "PCI driver for virtio devices"

depends on PCI
|
|
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).
|
|
|
|
If unsure, say M.

config VIRTIO_PCI_LEGACY

depends on VIRTIO_PCI
|
|
---help---
|
|
Virtio PCI Card 0.9.X Draft (circa 2014) and older device support.
|
|
|
|
This option enables building a transitional driver, supporting
|
|
both devices conforming to Virtio 1 specification, and legacy devices.
|
|
If disabled, you get a slightly smaller, non-transitional driver,
|
|
with no legacy compatibility.
|
|
|
|
So look out into your driveway. Do you have a flying car? If
|
|
so, you can happily disable this option and virtio will not
|
|
break. Otherwise, leave it set. Unless you're testing what
|
|
life will be like in The Future.
|
|
|
|
If unsure, say Y.

address in particular) can crash your system - you have been warned.
