Module iommu 

Available on crate feature iommu only.

Provide an interface for IOMMUs enabling I/O virtual address (IOVA) translation.

All IOMMUs consist of an IOTLB (Iotlb), which is backed by a data source that can deliver all mappings. For example, for vhost-user, that data source is the vhost-user front-end; i.e. IOTLB misses require sending a notification to the front-end and awaiting a reply that supplies the desired mapping.

Structs

IommuMemory

GuestMemory type that consists of an underlying GuestMemoryBackend object plus an Iommu.

IommuMemorySliceIterator

Iterates over VolatileSlices that together form an area in an IommuMemory.

Iotlb

Provides an IOTLB.

IotlbFails

Lists the subranges in I/O virtual address space that turned out to not be accessible when trying to access an IOVA range.

IotlbIterator

Iterates over a range of valid IOTLB mappings that together constitute a continuous range in I/O virtual address space.

IovaRange

Representation of an IOVA memory range (i.e. in the I/O virtual address space).

MappedRange

Representation of a mapped memory range in the underlying address space.

Enums

Error

Errors associated with IOMMU address translation.

Traits

Iommu

An IOMMU, allowing translation of I/O virtual addresses (IOVAs).
