| Doc Text | This update adds No-IOMMU mode for virtual function I/O (VFIO) drivers. The No-IOMMU mode provides the user with full user-space I/O (UIO) access to a direct memory access (DMA)-capable device without a I/O memory management unit (IOMMU). In this version, the No-IOMMU mode is not supported, and thus using this mode is not secure due to the lack of I/O management provided by IOMMU. | |||

However, it is recommended to use the VFIO No-IOMMU driver instead of UIO drivers, such as uio_pci_generic or igb_uio, for Red Hat Enterprise Linux guests that use the Data Plane Development Toolkit (DPDK) on hosts that use any of the following: - Single-root I/O virtualization (SR-IOV) - Open vSwitch-accelerated Data Plane Development Toolkit (OVS-DPDK) |
