-Unbind the VFs from the stock driver so they can be bound to the uio driver.
+Note:

+* Please note that due to security issues, the usage of older DPDK igb-uio
+  driver is not recommended. This document shows how to use the more secure
+  vfio-pci driver.

+  which details the constraint about trusted guests and add `disable_denylist=1`
+  to the vfio-pci params to use QAT. See also `this patch description <https://lkml.org/lkml/2020/7/23/1155>`_.

-Bind to the DPDK uio driver
+Bind to the vfio-pci driver
 ^^^^^^^^^^^^^^^^^^^^^^^^^^^

-Install the DPDK igb_uio driver, bind the VF PCI Device id to it and use lspci
-to confirm the VF devices are now in use by igb_uio kernel driver,
+Load the vfio-pci driver, bind the VF PCI Device id to it using the
+``dpdk-devbind.py`` script then use the ``--status`` option
+to confirm the VF devices are now in use by vfio-pci kernel driver,
 e.g. for the C62x device::

-    modprobe uio
-    insmod igb_uio.ko
-    echo "8086 37c9" > /sys/bus/pci/drivers/igb_uio/new_id
-    lspci -vvd:37c9
-
-
-Another way to bind the VFs to the DPDK UIO driver is by using the
-``dpdk-devbind.py`` script::
-
     cd to the top-level DPDK directory
-    ./usertools/dpdk-devbind.py -b igb_uio 0000:03:01.1
+    modprobe vfio-pci
+    usertools/dpdk-devbind.py -b vfio-pci 0000:03:01.1
+    usertools/dpdk-devbind.py --status
+
+Use ``modprobe vfio-pci disable_denylist=1`` from kernel 5.9 onwards.
+See note in the section `Binding the available VFs to the vfio-pci driver`_
+above.
