+Intel(R) FPGA 5GNR FEC Poll Mode Driver
+======================================
+
+The BBDEV FPGA 5GNR FEC poll mode driver (PMD) supports an FPGA implementation of a VRAN
+LDPC Encode / Decode 5GNR wireless acceleration function, using Intel's PCI-e and FPGA
+based Vista Creek device.
+
+Features
+--------
+
+FPGA 5GNR FEC PMD supports the following features:
+
+- 8 VFs per PF (physical device)
+- Maximum of 32 UL queues per VF
+- Maximum of 32 DL queues per VF
+- PCIe Gen-3 x8 Interface
+- MSI-X
+- SR-IOV
+
+Limitations
+-----------
+
+FPGA 5GNR FEC does not support the following:
+
+- Scatter-Gather function
+
+
+Installation
+--------------
+
+Section 3 of the DPDK manual provides instuctions on installing and compiling DPDK. The
+default set of bbdev compile flags may be found in config/common_base, where for example
+the flag to build the FPGA 5GNR FEC device, ``CONFIG_RTE_LIBRTE_PMD_BBDEV_FPGA_5GNR_FEC``,
+is already set. It is assumed DPDK has been compiled using for instance:
+
+.. code-block:: console
+
+  make install T=x86_64-native-linuxapp-gcc
+
+
+DPDK requires hugepages to be configured as detailed in section 2 of the DPDK manual.
+The bbdev test application has been tested with a configuration 40 x 1GB hugepages. The
+hugepage configuration of a server may be examined using:
+
+.. code-block:: console
+
+   grep Huge* /proc/meminfo
+
+
+Initialization
+--------------
+
+When the device first powers up, its PCI Physical Functions (PF) can be listed through this command:
+
+.. code-block:: console
+
+  sudo lspci -vd8086:0d8f
+
+The physical and virtual functions are compatible with Linux UIO drivers:
+``vfio`` and ``igb_uio``. However, in order to work the FPGA 5GNR FEC device firstly needs
+to be bound to one of these linux drivers through DPDK.
+
+
+Bind PF UIO driver(s)
+~~~~~~~~~~~~~~~~~~~~~
+
+Install the DPDK igb_uio driver, bind it with the PF PCI device ID and use
+``lspci`` to confirm the PF device is under use by ``igb_uio`` DPDK UIO driver.
+
+The igb_uio driver may be bound to the PF PCI device using one of three methods:
+
+
+1. PCI functions (physical or virtual, depending on the use case) can be bound to
+the UIO driver by repeating this command for every function.
+
+.. code-block:: console
+
+  cd <dpdk-top-level-directory>
+  insmod ./build/kmod/igb_uio.ko
+  echo "8086 0d8f" > /sys/bus/pci/drivers/igb_uio/new_id
+  lspci -vd8086:0d8f
+
+
+2. Another way to bind PF with DPDK UIO driver is by using the ``dpdk-devbind.py`` tool
+
+.. code-block:: console
+
+  cd <dpdk-top-level-directory>
+  ./usertools/dpdk-devbind.py -b igb_uio 0000:06:00.0
+
+where the PCI device ID (example: 0000:06:00.0) is obtained using lspci -vd8086:0d8f
+
+
+3. A third way to bind is to use ``dpdk-setup.sh`` tool
+
+.. code-block:: console
+
+  cd <dpdk-top-level-directory>
+  ./usertools/dpdk-setup.sh
+
+  select 'Bind Ethernet/Crypto/Baseband device to IGB UIO module'
+  or
+  select 'Bind Ethernet/Crypto/Baseband device to VFIO module' depending on driver required
+  enter PCI device ID
+  select 'Display current Ethernet/Crypto/Baseband device settings' to confirm binding
+
+
+In the same way the FPGA 5GNR FEC PF can be bound with vfio, but vfio driver does not
+support SR-IOV configuration right out of the box, so it will need to be patched.
+
+
+Enable Virtual Functions
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+Now, it should be visible in the printouts that PCI PF is under igb_uio control
+"``Kernel driver in use: igb_uio``"
+
+To show the number of available VFs on the device, read ``sriov_totalvfs`` file..
+
+.. code-block:: console
+
+  cat /sys/bus/pci/devices/0000\:<b>\:<d>.<f>/sriov_totalvfs
+
+  where 0000\:<b>\:<d>.<f> is the PCI device ID
+
+
+To enable VFs via igb_uio, echo the number of virtual functions intended to
+enable to ``max_vfs`` file..
+
+.. code-block:: console
+
+  echo <num-of-vfs> > /sys/bus/pci/devices/0000\:<b>\:<d>.<f>/max_vfs
+
+
+Afterwards, all VFs must be bound to appropriate UIO drivers as required, same
+way it was done with the physical function previously.
+
+Enabling SR-IOV via vfio driver is pretty much the same, except that the file
+name is different:
+
+.. code-block:: console
+
+  echo <num-of-vfs> > /sys/bus/pci/devices/0000\:<b>\:<d>.<f>/sriov_numvfs
