| config VIRTIO |
| tristate |
| ---help--- |
| 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. |

| config VIRTIO_BALLOON |
| tristate "Virtio balloon driver" |
| depends on VIRTIO |
| ---help--- |
| This driver supports increasing and decreasing the amount |
| of memory within a KVM guest. |
| |
| If unsure, say M. |
| |
| config VIRTIO_MMIO |
| tristate "Platform bus driver for memory mapped virtio devices" |
| depends on HAS_IOMEM |
| select VIRTIO |
| ---help--- |
| This drivers provides support for memory mapped virtio |
| platform device driver. |
| |
| If unsure, say N. |

| config VIRTIO_MMIO_CMDLINE_DEVICES |
| bool "Memory mapped virtio devices parameter parsing" |
| depends on VIRTIO_MMIO |
| ---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. |
| |
| If unsure, say 'N'. |
