description:
|
|
The Xen IOMMU represents the Xen grant table interface. Grant mappings
|
|
are to be used with devices connected to the Xen IOMMU using the "iommus"
|
|
property, which also specifies the ID of the backend domain.
|
|
The binding is required to restrict memory access using Xen grant mappings.
