3 tristate "VFIO support for VIRTIO NET PCI VF devices"
7 This provides migration support for VIRTIO NET PCI VF devices
8 using the VFIO framework. Migration support requires the
9 SR-IOV PF device to support specific VIRTIO extensions,
10 otherwise this driver provides no additional functionality
13 Migration support in this driver relies on dirty page tracking
14 provided by the IOMMU hardware and exposed through IOMMUFD, any
15 other use cases are dis-recommended.
17 If you don't know what to do here, say N.

21 depends on VIRTIO_VFIO_PCI && VIRTIO_PCI_ADMIN_LEGACY
24 This extends the virtio-vfio-pci driver to support legacy I/O
25 access, allowing use of legacy virtio drivers with VIRTIO NET
26 PCI VF devices. Legacy I/O support requires the SR-IOV PF
27 device to support and enable specific VIRTIO extensions,
28 otherwise this driver provides no additional functionality
