depends on PCI && EXPERIMENTAL
select VIRTIO
select VIRTIO_RING
---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 (EXPERIMENTAL)"
select VIRTIO
select VIRTIO_RING
---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 (EXPERIMENTAL)"
depends on EXPERIMENTAL
select VIRTIO
select VIRTIO_RING
---help---
This drivers provides support for memory mapped virtio
platform device driver.
If unsure, say N.
