Linux Drivers
``vfio-pci`` kernel module rather than ``igb_uio`` or ``uio_pci_generic``.
For more details see :ref:`linux_gsg_binding_kernel` below.
+.. note::
+
+ If the devices used for DPDK are bound to the ``uio_pci_generic`` kernel module,
+ please make sure that the IOMMU is disabled or passthrough. One can add
+ ``intel_iommu=off`` or ``amd_iommu=off`` or ``intel_iommu=on iommu=pt``in GRUB
+ command line on x86_64 systems, or add ``iommu.passthrough=1`` on arm64 system.
+
Since DPDK release 1.7 onward provides VFIO support, use of UIO is optional
for platforms that support using VFIO.
