The\n+default set of bbdev compile flags may be found in config/common_base, where for example\n+the flag to build the ACC100 5G/4G FEC device, ``CONFIG_RTE_LIBRTE_PMD_BBDEV_ACC100``,\n+is already set.\n+\n+DPDK requires hugepages to be configured as detailed in section 2 of the DPDK manual.\n+The bbdev test application has been tested with a configuration 40 x 1GB hugepages. The\n+hugepage configuration of a server may be examined using:\n+\n+.. code-block:: console\n+\n+ grep Huge* /proc/meminfo\n+\n+\n+Initialization\n+--------------\n+\n+When the device first powers up, its PCI Physical Functions (PF) can be listed through this command:\n+\n+.. code-block:: console\n+\n+ sudo lspci -vd8086:0d5c\n+\n+The physical and virtual functions are compatible with Linux UIO drivers:\n+``vfio`` and ``igb_uio``. However, in order to work the ACC100 5G/4G\n+FEC device firstly needs to be bound to one of these linux drivers through DPDK.\n+\n+\n+Bind PF UIO driver(s)\n+~~~~~~~~~~~~~~~~~~~~~\n+\n+Install the DPDK igb_uio driver, bind it with the PF PCI device ID and use\n+``lspci`` to confirm the PF device is under use by ``igb_uio`` DPDK UIO driver.\n+\n+The igb_uio driver may be bound to the PF PCI device using one of three methods:\n+\n+\n+1. PCI functions (physical or virtual, depending on the use case) can be bound to\n+the UIO driver by repeating this command for every function.\n+\n+.. code-block:: console\n+\n+ cd <dpdk-top-level-directory>\n+ insmod ./build/kmod/igb_uio.ko\n+ echo \"8086 0d5c\" > /sys/bus/pci/drivers/igb_uio/new_id\n+ lspci -vd8086:0d5c\n+\n+\n+2. Another way to bind PF with DPDK UIO driver is by using the ``dpdk-devbind.py`` tool\n+\n+.. code-block:: console\n+\n+ cd <dpdk-top-level-directory>\n+ ./usertools/dpdk-devbind.py -b igb_uio 0000:06:00.0\n+\n+where the PCI device ID (example: 0000:06:00.0) is obtained using lspci -vd8086:0d5c\n+\n+\n+3. A third way to bind is to use ``dpdk-setup.sh`` tool\n+\n+.. code-block:: console\n+\n+ cd <dpdk-top-level-directory>\n+ ./usertools/dpdk-setup.sh\n+\n+ select 'Bind Ethernet/Crypto/Baseband device to IGB UIO module'\n+ or\n+ select 'Bind Ethernet/Crypto/Baseband device to VFIO module' depending on driver required\n+ enter PCI device ID\n+ select 'Display current Ethernet/Crypto/Baseband device settings' to confirm binding\n+\n+\n+In the same way the ACC100 5G/4G FEC PF can be bound with vfio, but vfio driver does not\n+support SR-IOV configuration right out of the box, so it will need to be patched.\n+\n+\n+Enable Virtual Functions\n+~~~~~~~~~~~~~~~~~~~~~~~~\n+\n+Now, it should be visible in the printouts that PCI PF is under igb_uio control\n+\"``Kernel driver in use: igb_uio``\"\n+\n+To show the number of available VFs on the device, read ``sriov_totalvfs`` file..\n+\n+.. code-block:: console\n+\n+ cat /sys/bus/pci/devices/0000\\:<b>\\:<d>.<f>/sriov_totalvfs\n+\n+ where 0000\\:<b>\\:<d>.<f> is the PCI device ID\n+\n+\n+To enable VFs via igb_uio, echo the number of virtual functions intended to\n+enable to ``max_vfs`` file..\n+\n+.. code-block:: console\n+\n+ echo <num-of-vfs> > /sys/bus/pci/devices/0000\\:<b>\\:<d>.<f>/max_vfs\n+\n+\n+Afterwards, all VFs must be bound to appropriate UIO drivers as required, same\n+way it was done with the physical function previously.\n+\n+Enabling SR-IOV via vfio driver is pretty much the same, except that the file\n+name is different:\n+\n+.. code-block:: console\n+\n+ echo <num-of-vfs> > /sys/bus/pci/devices/0000\\:<b>\\:<d>.<f>/sriov_numvfs\n+\n+\n+Configure the VFs through PF\n+~~~~~~~~~~~~~~~~~~~~~~~~~~~~\n+\n+The PCI virtual functions must be configured before working or getting assigned\n+to VMs/Containers. The configuration involves allocating the number of hardware\n+queues, priorities, load balance, bandwidth and other settings necessary for the\n+device to perform FEC functions.\n+\n+This configuration needs to be executed at least once after reboot or PCI FLR and can\n+be achieved by using the function ``acc100_configure()``, which sets up the\n+parameters defined in ``acc100_conf`` structure.\n+\n+Test Application\n+----------------\n+\n+BBDEV provides a test application, ``test-bbdev.py`` and range of test data for testing\n+the functionality of ACC100 5G/4G FEC encode and decode, depending on the device's\n+capabilities. The test application is located under app->test-bbdev folder and has the\n+following options:\n+\n+.. code-block:: console\n+\n+ \"-p\", \"--testapp-path\": specifies path to the bbdev test app.\n+ \"-e\", \"--eal-params\"\t: EAL arguments which are passed to the test app.\n+ \"-t\", \"--timeout\"\t: Timeout in seconds (default=300).\n+ \"-c\", \"--test-cases\"\t: Defines test cases to run. Run all if not specified.\n+ \"-v\", \"--test-vector\"\t: Test vector path (default=dpdk_path+/app/test-bbdev/test_vectors/bbdev_null.data).\n+ \"-n\", \"--num-ops\"\t: Number of operations to process on device (default=32).\n+ \"-b\", \"--burst-size\"\t: Operations enqueue/dequeue burst size (default=32).\n+ \"-s\", \"--snr\"\t\t: SNR in dB used when generating LLRs for bler tests.\n+ \"-s\", \"--iter_max\"\t: Number of iterations for LDPC decoder.\n+ \"-l\", \"--num-lcores\"\t: Number of lcores to run (default=16).\n+ \"-i\", \"--init-device\" : Initialise PF device with default values.\n+\n+\n+To execute the test application tool using simple decode or encode data,\n+type one of the following:\n+\n+.. code-block:: console\n+\n+ ./test-bbdev.py -c validation -n 64 -b 1 -v ./ldpc_dec_default.data\n+ ./test-bbdev.py -c validation -n 64 -b 1 -v ./ldpc_enc_default.data\n+\n+\n+The test application ``test-bbdev.py``, supports the ability to configure the PF device with\n+a default set of values, if the \"-i\" or \"- -init-device\" option is included. The default values\n+are defined in test_bbdev_perf.c.\n+\n+\n+Test Vectors\n+~~~~~~~~~~~~\n+\n+In addition to the simple LDPC decoder and LDPC encoder tests, bbdev also provides\n+a range of additional tests under the test_vectors folder, which may be useful. The results\n+of these tests will depend on the ACC100 5G/4G FEC capabilities which may cause some\n+testcases to be skipped, but no failure should be reported.\ndiff --git a/doc/guides/bbdevs/index.rst b/doc/guides/bbdevs/index.rst\nindex a8092dd..4445cbd 100644\n--- a/doc/guides/bbdevs/index.rst\n+++ b/doc/guides/bbdevs/index.rst\n@@ -13,3 +13,4 @@ Baseband Device Drivers\n turbo_sw\n fpga_lte_fec\n fpga_5gnr_fec\n+ acc100\ndiff --git a/doc/guides/rel_notes/release_20_11.rst b/doc/guides/rel_notes/release_20_11.rst\nindex df227a1..b3ab614 100644\n--- a/doc/guides/rel_notes/release_20_11.rst\n+++ b/doc/guides/rel_notes/release_20_11.rst\n@@ -55,6 +55,12 @@ New Features\n Also, make sure to start the actual text at the margin.\n =======================================================\n \n+* **Added Intel ACC100 bbdev PMD.**\n+\n+ Added a new ``acc100`` bbdev driver for the Intel\\ |reg| ACC100 accelerator\n+ also known as Mount Bryce.
