+Assuming you are running on at least a 4.5 kernel, you can use the stock kernel.org QAT
+driver to start the QAT hardware.
+
+The steps below assume you are:
+
+* Running DPDK on a platform with one ``C62x`` device.
+* On a kernel at least version 4.5.
+
+In BIOS ensure that SRIOV is enabled and VT-d is disabled.
+
+Ensure the QAT driver is loaded on your system, by executing::
+
+    lsmod | grep qat

+You should see the following output::

+    3f:00.0 Co-processor: Intel Corporation Device 37c8
+
+For each c62x device there are 3 PFs.
+Using the sysfs, for each PF, enable the 16 VFs::
+
+    echo 16 > /sys/bus/pci/drivers/c6xx/0000\:1a\:00.0/sriov_numvfs
+
+If you get an error, it's likely you're using a QAT kernel driver earlier than kernel 4.5.
+
+To verify that the VFs are available for use - use ``lspci -d:37c9`` to confirm
+the bdf of the 48 VF devices are available per ``C62x`` device.
+
+To complete the installation - follow instructions in `Binding the available VFs to the DPDK UIO driver`_.
