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 drivers 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). |
|
|
|
Currently, the ABI is not considered stable so there is no guarantee |
|
that this version of the driver will work with your VMM. |

If unsure, say M. |

|
of memory within a KVM guest. |

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

See Documentation/kernel-parameters.txt for details. |
