+.. note::
+
+ If UEFI secure boot is enabled, the Linux kernel may disallow the use of
+ UIO on the system. Therefore, devices for use by DPDK should be bound to the
+ ``vfio-pci`` kernel module rather than ``igb_uio`` or ``uio_pci_generic``.
+ For more details see :ref:`linux_gsg_binding_kernel`.
