+Intel(R) ACC200 vRAN Dedicated Accelerator Poll Mode Driver
+===========================================================
+
+The Intel® vRAN Dedicated Accelerator ACC200 peripheral enables cost-effective
+4G and 5G next-generation virtualized Radio Access Network (vRAN) solutions
+integrated on Sapphire Rapids Edge Enhanced Processor (SPR-EE)
+Intel(R)7 based Xeon(R) multi-core server processor.
+
+Features
+--------
+
+The ACC200 includes a 5G Low Density Parity Check (LDPC) encoder/decoder,
+rate match/dematch, Hybrid Automatic Repeat Request (HARQ) with access to DDR
+memory for buffer management, a 4G Turbo encoder/decoder, a
+Fast Fourier Transform (FFT) block providing DFT/iDFT processing offload
+for the 5G Sounding Reference Signal (SRS), a Queue Manager (QMGR), and
+a DMA subsystem.
+There is no dedicated on-card memory for HARQ, this is using coherent memory
+on the CPU side.
+
+These correspond to the following features exposed by the PMD:
+
+- LDPC Encode in the Downlink (5GNR)
+- LDPC Decode in the Uplink (5GNR)
+- Turbo Encode in the Downlink (4G)
+- Turbo Decode in the Uplink (4G)
+- FFT processing
+- SR-IOV with 16 VFs per PF
+- Maximum of 256 queues per VF
+- MSI
+
+ACC200 PMD supports the following BBDEV capabilities:
+
+* For the LDPC encode operation:
+   - ``RTE_BBDEV_LDPC_CRC_24B_ATTACH`` :  set to attach CRC24B to CB(s).

+
+Installation
+------------
+
+Section 3 of the DPDK manual provides instructions on installing and compiling DPDK.
+
+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 these commands for ACC200:
+
+.. code-block:: console
+
+  sudo lspci -vd8086:57c0
+
+The physical and virtual functions are compatible with Linux UIO drivers:
+``vfio`` and ``igb_uio``. However, in order to work the 5G/4G
+FEC device first 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 two methods
+for ACC200:
+
+
+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 57c0" > /sys/bus/pci/drivers/igb_uio/new_id
+  lspci -vd8086:57c0
+
+
+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:f7:00.0
+
+where the PCI device ID (example: 0000:f7:00.0) is obtained using lspci -vd8086:57c0
+
+
+In a similar way the PF may be bound with vfio-pci as any PCIe device.
+
+
+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
+
+
+Configure the VFs through PF
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The PCI virtual functions must be configured before working or getting assigned
+to VMs/Containers. The configuration involves allocating the number of hardware
+queues, priorities, load balance, bandwidth and other settings necessary for the
+device to perform FEC functions.
+
+This configuration needs to be executed at least once after reboot or PCI FLR and can
+be achieved by using the functions ``rte_acc200_configure()``,
+which sets up the parameters defined in the compatible ``acc200_conf`` structure.
+
+Test Application
+----------------
+
+BBDEV provides a test application, ``test-bbdev.py`` and range of test data for testing
+the functionality of the device, depending on the device's
+capabilities. The test application is located under app->test-bbdev folder and has the
+following options:
+
+.. code-block:: console
+
+  "-p", "--testapp-path": specifies path to the bbdev test app.
+  "-e", "--eal-params"	: EAL arguments which are passed to the test app.
+  "-t", "--timeout"	: Timeout in seconds (default=300).
+  "-c", "--test-cases"	: Defines test cases to run. Run all if not specified.
+  "-v", "--test-vector"	: Test vector path.
+  "-n", "--num-ops"	: Number of operations to process on device (default=32).
+  "-b", "--burst-size"	: Operations enqueue/dequeue burst size (default=32).
+  "-s", "--snr"		: SNR in dB used when generating LLRs for bler tests.
+  "-s", "--iter_max"	: Number of iterations for LDPC decoder.
+  "-l", "--num-lcores"	: Number of lcores to run (default=16).
+  "-i", "--init-device" : Initialise PF device with default values.
+
+
+To execute the test application tool using simple decode or encode data,
+type one of the following:
+
+.. code-block:: console
+
+  ./test-bbdev.py -c validation -n 64 -b 1 -v ./ldpc_dec_default.data
+  ./test-bbdev.py -c validation -n 64 -b 1 -v ./ldpc_enc_default.data
+
+
+The test application ``test-bbdev.py``, supports the ability to configure the
+PF device with a default set of values, if the "-i" or "- -init-device" option
+is included. The default values are defined in test_bbdev_perf.c.
+
+
+Test Vectors
+~~~~~~~~~~~~
+
+In addition to the simple LDPC decoder and LDPC encoder tests,
+bbdev also provides a range of additional tests under the test_vectors folder,
+which may be useful.
+The results of these tests will depend on the device capabilities which may
+cause some testcases to be skipped, but no failure should be reported.
+
+
+Alternate Baseband Device configuration tool
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+On top of the embedded configuration feature supported in test-bbdev using
+"- -init-device" option mentioned above, there is also a tool available to
+perform that device configuration using a companion application.
+The ``pf_bb_config`` application notably enables then to run bbdev-test from
+the VF and not only limited to the PF as captured above.
+
+See for more details: https://github.com/intel/pf-bb-config
+
+Specifically for the BBDEV ACC200 PMD, the command below can be used:
+
+.. code-block:: console
+
+  ./pf_bb_config ACC200 -c ./acc200/acc200_config_vf_5g.cfg
+  ./test-bbdev.py -e="-c 0xff0 -a${VF_PCI_ADDR}" -c validation -n 64 -b 64 -l 1 -v ./ldpc_dec_default.data
