[dpdk-dev] [PATCH] BBDEV turbo_sw PMD compilation fix

[dpdk-dev] [PATCH] BBDEV turbo_sw PMD compilation fix

[Nicolas Chautru]

Based on discussion with maintainer, pushing first a patch to help
maintenance of the baseband_turbo_sw which had been lacking.
The documentation is clarified to point to steps on building the
SDK libraries which are now publicly available. (Cosmetic changes
to the webpage containing these SDK  will happen in parallel
based on feedback from maintainer).
A compile flag is added to be able to build the turbo_sw PMD
when the SDK libraries for AVX2 are installed or not. 
In both cases this can be compiled with gcc RTE_TARGET. 
Missing meson build support is also added. 

Note that additional BBDEV changes pushed in previous v1
https://patches.dpdk.org/project/dpdk/list/?series=4657
will be added in a separate v2 patchset which will
depend on this very patchset.

-FlexRAN SDK Download
-~~~~~~~~~~~~~~~~~~~~
-
-To build DPDK with the *baseband_turbo_sw* PMD the user is required to download
-the export controlled ``FlexRAN SDK`` Libraries. An account at `Intel Resource
-Design Center <https://www.intel.com/content/www/us/en/design/resource-design-center.html>`_
-needs to be registered.
-
-Once registered, the user needs to log in, and look for
-*Intel FlexRAN Software Release Package -18-09* to download or directly through
-this `link <https://cdrdv2.intel.com/v1/dl/getContent/605167>`_.
-
-After download is complete, the user needs to unpack and compile on their
-system before building DPDK.
-
-The following table maps DPDK versions with past FlexRAN SDK releases:
-
-.. _table_flexran_releases:
-
-.. table:: DPDK and FlexRAN SDK releases compliance

-   19.02                  18.09
-   =====================  ============================
-
-FlexRAN SDK Installation
-~~~~~~~~~~~~~~~~~~~~~~~~
-
-The following are pre-requisites for building FlexRAN SDK Libraries:
- (a) An AVX2 supporting machine
- (b) CentOS Linux release 7.2.1511 (Core) operating system
- (c) Intel ICC 18.0.1 20171018 compiler installed
-
-The following instructions should be followed in this exact order:
-
-#. Set the environment variables:
-
-    .. code-block:: console
-
-        source <path-to-icc-compiler-install-folder>/linux/bin/compilervars.sh intel64 -platform linux
-
-#. Extract the ``605167-flexran-18-09-tar.gz`` package:
-
-    .. code-block:: console
-
-        mkdir FlexRAN-18.09
-        tar xvzf 605167-flexran-18-09-tar.gz -C FlexRAN-18.09/
-
-#. Run the SDK extractor script and accept the license:
-
-    .. code-block:: console
-
-        cd <path-to-workspace>/FlexRAN-18.09/
-        ./SDK-18.09.sh
-
-#. Generate makefiles based on system configuration:
-
-    .. code-block:: console
-
-        cd <path-to-workspace>/FlexRAN-18.09/SDK-18.09/sdk/
-        ./create-makefiles-linux.sh
-
-#. A build folder is generated in this form ``build-<ISA>-<CC>``, enter that
-   folder and install:
-
-    .. code-block:: console
-
-        cd build-avx2-icc/
-        make && make install
-
-
-Initialization
---------------
-
-In order to enable this virtual bbdev PMD, the user must:
-
-* Build the ``FLEXRAN SDK`` libraries (explained in Installation section).
-
-* Export the environmental variables ``FLEXRAN_SDK`` to the path where the
-  FlexRAN SDK libraries were installed. And ``DIR_WIRELESS_SDK`` to the path
-  where the libraries were extracted.
-
-Example:
-
-.. code-block:: console
-
-    export FLEXRAN_SDK=<path-to-workspace>/FlexRAN-18.09/SDK-18.09/sdk/build-avx2-icc/install
-    export DIR_WIRELESS_SDK=<path-to-workspace>/FlexRAN-18.09/SDK-18.09/sdk/
-
-
-* Set ``CONFIG_RTE_LIBRTE_PMD_BBDEV_TURBO_SW=y`` in DPDK common configuration
-  file ``config/common_base``.
-
-To use the PMD in an application, user must:
-
-- Call ``rte_vdev_init("baseband_turbo_sw")`` within the application.
-
-- Use ``--vdev="baseband_turbo_sw"`` in the EAL options, which will call ``rte_vdev_init()`` internally.
-
-The following parameters (all optional) can be provided in the previous two calls:
-
-* ``socket_id``: Specify the socket where the memory for the device is going to be allocated
-  (by default, *socket_id* will be the socket where the core that is creating the PMD is running on).
-
-* ``max_nb_queues``: Specify the maximum number of queues in the device (default is ``RTE_MAX_LCORE``).
-
-Example:
-~~~~~~~~
-
-.. code-block:: console
-
-    ./test-bbdev.py -e="--vdev=baseband_turbo_sw,socket_id=0,max_nb_queues=8" \
-    -c validation -v ./turbo_*_default.data

+SW FEC Poll Mode Driver
+=========================
+
+The SW FEC PMD (**baseband_turbo_sw**) provides a software only poll mode bbdev
+driver that can optionally utilize Intel optimized libraries for LTE and 5GNR
+Layer 1 workloads acceleration.
+
+Note that the driver can also be built without any dependency with reduced
+functionality for maintenance purpose.
+
+To enable linking to the SDK libraries see detailed installation section below.
+Two flags can be enabled depending on whether the target machine can support
+AVX2 and AVX512 instructions sets and the related SDK libraries for vectorized
+signal processing functions are installed :
+- CONFIG_RTE_BBDEV_SDK_AVX2
+- CONFIG_RTE_BBDEV_SDK_AVX512
+By default these 2 flags are disabled by default. For AVX2 machine and SDK
+library installed then the first flag can be enabled. For AVX512 machine and
+SDK library installed then both flags can be enabled for full real time capability.
+
+This PMD supports the functions: FEC, Rate Matching and CRC functions detailed
+in the Features section.
+
+Features
+--------
+
+SW FEC PMD can support for the following capabilities when the SDK libraries
+are used:
+
+For the LTE encode operation:
+
+* ``RTE_BBDEV_TURBO_CRC_24A_ATTACH``
+* ``RTE_BBDEV_TURBO_CRC_24B_ATTACH``
+* ``RTE_BBDEV_TURBO_RATE_MATCH``
+* ``RTE_BBDEV_TURBO_RV_INDEX_BYPASS``
+
+For the LTE decode operation:
+
+* ``RTE_BBDEV_TURBO_SUBBLOCK_DEINTERLEAVE``
+* ``RTE_BBDEV_TURBO_CRC_TYPE_24B``
+* ``RTE_BBDEV_TURBO_POS_LLR_1_BIT_IN``
+* ``RTE_BBDEV_TURBO_NEG_LLR_1_BIT_IN``
+* ``RTE_BBDEV_TURBO_DEC_TB_CRC_24B_KEEP``
+* ``RTE_BBDEV_TURBO_EARLY_TERMINATION``
+
+For the 5G NR LDPC encode operation:
+
+* ``RTE_BBDEV_LDPC_RATE_MATCH``
+* ``RTE_BBDEV_LDPC_CRC_24A_ATTACH``
+* ``RTE_BBDEV_LDPC_CRC_24B_ATTACH``
+
+For the 5G NR LDPC decode operation:
+
+* ``RTE_BBDEV_LDPC_CRC_TYPE_24B_CHECK``
+* ``RTE_BBDEV_LDPC_CRC_TYPE_24A_CHECK``
+* ``RTE_BBDEV_LDPC_CRC_TYPE_24B_DROP``
+* ``RTE_BBDEV_LDPC_HQ_COMBINE_IN_ENABLE``
+* ``RTE_BBDEV_LDPC_HQ_COMBINE_OUT_ENABLE``
+* ``RTE_BBDEV_LDPC_ITERATION_STOP_ENABLE``
+
+Limitations
+-----------
+
+* In-place operations for encode and decode are not supported
+
+Installation

+
+FlexRAN FEC SDK Download
+~~~~~~~~~~~~~~~~~~~~
+
+As an option it is possible to link this driver with FleXRAN SDK libraries
+which can enable real time signal processing using AVX instructions.
+
+These libraries are available through this link `link <https://software.intel.com/en-us/articles/flexran-lte-and-5g-nr-fec-software-development-kit-modules>`_.
+
+After download is complete, the user needs to unpack and compile on their
+system before building DPDK.
+
+The following table maps DPDK versions with past FlexRAN SDK releases:
+
+.. _table_flexran_releases:

+
+FlexRAN SDK Installation
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+Note that the installation of these libraries is optional.
+
+The following are pre-requisites for building FlexRAN SDK Libraries:
+ (a) An AVX2 or AVX512 supporting machine
+ (b) CentOS Linux release 7.2.1511 (Core) operating system is advised
+ (c) Intel ICC 18.0.1 20171018 compiler or more recent and related libraries
+     ICC is available with a free community license `link <https://software.intel.com/en-us/system-studio/choose-download#technical>`_.
+
+The following instructions should be followed in this exact order:
+
+#. Set the environment variables:
+
+    .. code-block:: console
+
+        source <path-to-icc-compiler-install-folder>/linux/bin/compilervars.sh intel64 -platform linux
+
+#. Run the SDK extractor script and accept the license:
+
+    .. code-block:: console
+
+        cd <path-to-workspace>
+        ./FlexRAN-FEC-SDK-19-04.sh
+
+#. Generate makefiles based on system configuration:
+
+    .. code-block:: console
+
+        cd <path-to-workspace>/FlexRAN-FEC-SDK-19-04/sdk/
+        ./create-makefiles-linux.sh
+
+#. A build folder is generated in this form ``build-<ISA>-<CC>``, enter that
+   folder and install:
+
+    .. code-block:: console
+
+        cd build-avx512-icc/
+        make && make install
+

+In order to enable this virtual bbdev PMD, the user may:
+
+* Build the ``FLEXRAN SDK`` libraries (explained in Installation section).
+
+* Export the environmental variables ``FLEXRAN_SDK`` to the path where the
+  FlexRAN SDK libraries were installed. And ``DIR_WIRELESS_SDK`` to the path
+  where the libraries were extracted.
+
+Example:
+
+.. code-block:: console
+
+    export FLEXRAN_SDK=<path-to-workspace>/FlexRAN-FEC-SDK-19-04/sdk/build-avx2-icc/install
+    export DIR_WIRELESS_SDK=<path-to-workspace>/FlexRAN-FEC-SDK-19-04/sdk/build-avx2-icc/
+
+* Set ``CONFIG_RTE_BBDEV_SDK_AVX2=y`` and ``CONFIG_RTE_BBDEV_SDK_AVX512=y``
+  in DPDK common configuration file ``config/common_base`` to be able to use
+  the SDK libraries as mentioned above.
+  For AVX2 machine it is possible to only enable CONFIG_RTE_BBDEV_SDK_AVX2
+  for limited 4G functionality.
+  If no flag are set the PMD driver will still build but its capabilities
+  will be limited accordingly.
+
+To use the PMD in an application, user must:
+
+- Call ``rte_vdev_init("baseband_turbo_sw")`` within the application.
+
+- Use ``--vdev="baseband_turbo_sw"`` in the EAL options, which will call ``rte_vdev_init()`` internally.

Re: [dpdk-dev] [PATCH] baseband/turbo_sw: Option to build turbosw PMD without SDK

[Thomas Monjalon]

> Meson build support.

There are 3 different things which deserve 3 patches.

About the doc, I am surprised it looks to be fully rewritten.
I think you need to double check it.

[dpdk-dev] [PATCH v2 0/3] BBDEV turbo_sw PMD compilation fix

[Nicolas Chautru]

Updated in v2 : Split into 3 patches as recommended. 

Based on discussion with maintainer, pushing first a patch to help
maintenance of the baseband_turbo_sw which had been lacking.
The documentation is clarified to point to steps on building the
SDK libraries which are now publicly available. (Cosmetic changes
to the webpage containing these SDK  will happen in parallel
based on feedback from maintainer).
A compile flag is added to be able to build the turbo_sw PMD
when the SDK libraries for AVX2 are installed or not. 
In both cases this can be compiled with gcc RTE_TARGET. 
Missing meson build support is also added. 

Note that additional BBDEV changes pushed in previous v1
https://patches.dpdk.org/project/dpdk/list/?series=4657
will be added in a separate v2 patchset which will
depend on this very patchset.

-SW Turbo Poll Mode Driver
+SW FEC Poll Mode Driver
 =========================
 
-The SW Turbo PMD (**baseband_turbo_sw**) provides a poll mode bbdev driver that utilizes
-Intel optimized libraries for LTE Layer 1 workloads acceleration. This PMD
-supports the functions: Turbo FEC, Rate Matching and CRC functions.
+The SW FEC PMD (**baseband_turbo_sw**) provides a software only poll mode bbdev
+driver that can optionally utilize Intel optimized libraries for LTE and 5GNR
+Layer 1 workloads acceleration.
+
+Note that the driver can also be built without any dependency with reduced
+functionality for maintenance purpose.
+
+To enable linking to the SDK libraries see detailed installation section below.
+Two flags can be enabled depending on whether the target machine can support
+AVX2 and AVX512 instructions sets and the related SDK libraries for vectorized
+signal processing functions are installed :
+- CONFIG_RTE_BBDEV_SDK_AVX2
+- CONFIG_RTE_BBDEV_SDK_AVX512
+By default these 2 flags are disabled by default. For AVX2 machine and SDK
+library installed then the first flag can be enabled. For AVX512 machine and
+SDK library installed then both flags can be enabled for full real time capability.
+
+This PMD supports the functions: FEC, Rate Matching and CRC functions detailed
+in the Features section.

There seems two groups of changes in this patch,
- new SDK related changes,
- and renaming 's/Turbo/FEC'
For second one can you please put a brief description into commit log? Why Turbo
needs to be FEC. (This even can be a separate patch)

Is 5GNR Layer 1 workloads acceleration available in this stage of the PMD?

Fair enough. Name could be more accurate as Turbo means so different things but this is fairly cosmetic and we can change this in a future patchset. 
This would also require changes in the code which is not required now. So will put it back as before now.

The SDK provided on the link supports both standards and set of libraries and these how they are referred on the webpage : "FlexRAN LTE and 5G NR FEC Software Development Kit Modules".
Still if you reckon this is confusing given this current PMD only links to the 4G ones then I can remove any mention of 5GNR. 
The related turbo_sw in patchwork v1 is extending this and hence documentation will eventually mention back 5GNR anyway. Will change now.

No problem. The intention was to highlight where this is going with 2 sets of functionality depending on HW dependency as it is not necessarily obvious now that these are split into 2 patchsets. 
But you are right that this can be rephrased to be limited to AVX2 for now. 

Thanks

[dpdk-dev] [PATCH v2 0/3] baseband/fpga_lte_fec: adding driver for FEC on FPGA

[Nicolas Chautru]

This is adding a new PMD driver for BBDEV device based on 
FPGA implementation on PAC N3000 HW to provide FEC 4G acceleration. 
v1 was shared earlier on this patchwork :
https://patches.dpdk.org/patch/53409/
The existing BBDEV test framework is still supported. 

Main updates based on feedback during the last v1 were:
- correct the documentation which was arguably misleading in
hinting that ICC was required. There is no dependency whatsoever. 
- add meson build support

Note that a number of other BBDEV patches are in v1 here and 
will be resubmitted for 19.08 rc1

[dpdk-dev] [PATCH v3] baseband/fpga_lte_fec: adding driver for FEC on FPGA

[Nicolas Chautru]

Update since v2 : Squashing 3 previous patches into one as recommended.  

This is adding a new PMD driver for BBDEV device based on FPGA implementation on PAC N3000 HW to provide FEC 4G acceleration. 
v1 was shared earlier on this patchwork :
https://patches.dpdk.org/patch/53409/
The existing BBDEV test framework is still supported. 

Main updates based on feedback during the last v1 were:
- correct the documentation which was arguably misleading in hinting that ICC was required. There is no dependency whatsoever. 
- add meson build support

Note that a number of other BBDEV patches are in v1 here and will be resubmitted for 19.08 rc1
https://patches.dpdk.org/project/dpdk/list/?series=4657

+Intel(R) FPGA LTE FEC Poll Mode Driver
+======================================
+
+The BBDEV FPGA LTE FEC poll mode driver (PMD) supports an FPGA implementation of a VRAN
+Turbo Encode / Decode LTE wireless acceleration function, using Intel's PCI-e and FPGA
+based Vista Creek device.
+
+Features
+--------
+
+FPGA LTE FEC PMD supports the following features:
+
+- Turbo Encode in the DL with total throughput of 4.5 Gbits/s
+- Turbo Decode in the UL with total throughput of 1.5 Gbits/s assuming 8 decoder iterations
+- 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
+
+
+FPGA LTE FEC PMD supports the following BBDEV capabilities:
+
+* For the turbo encode operation:
+   - ``RTE_BBDEV_TURBO_CRC_24B_ATTACH`` :  set to attach CRC24B to CB(s)
+   - ``RTE_BBDEV_TURBO_RATE_MATCH`` :  if set then do not do Rate Match bypass
+   - ``RTE_BBDEV_TURBO_ENC_INTERRUPTS`` :  set for encoder dequeue interrupts
+
+
+* For the turbo decode operation:
+   - ``RTE_BBDEV_TURBO_CRC_TYPE_24B`` :  check CRC24B from CB(s)
+   - ``RTE_BBDEV_TURBO_SUBBLOCK_DEINTERLEAVE`` :  perform subblock de-interleave
+   - ``RTE_BBDEV_TURBO_DEC_INTERRUPTS`` :  set for decoder dequeue interrupts
+   - ``RTE_BBDEV_TURBO_NEG_LLR_1_BIT_IN`` :  set if negative LLR encoder i/p is supported
+   - ``RTE_BBDEV_TURBO_DEC_TB_CRC_24B_KEEP`` :  keep CRC24B bits appended while decoding
+
+
+Limitations
+-----------
+
+FPGA LTE 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 LTE FEC device, ``CONFIG_RTE_LIBRTE_PMD_FPGA_LTE_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 -vd1172:5052
+
+The physical and virtual functions are compatible with Linux UIO drivers:
+``vfio`` and ``igb_uio``. However, in order to work the FPGA LTE 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 "1172 5052" > /sys/bus/pci/drivers/igb_uio/new_id
+  lspci -vd1172:
+
+
+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 -vd1172:
+
+
+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 LTE 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
+
+
+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 function ``fpga_lte_fec_configure()``, which sets up the
+parameters defined in ``fpga_lte_fec_conf`` structure:
+
+.. code-block:: c
+
+  struct fpga_lte_fec_conf {
+      bool pf_mode_en;
+      uint8_t vf_ul_queues_number[FPGA_LTE_FEC_NUM_VFS];
+      uint8_t vf_dl_queues_number[FPGA_LTE_FEC_NUM_VFS];
+      uint8_t ul_bandwidth;
+      uint8_t dl_bandwidth;
+      uint8_t ul_load_balance;
+      uint8_t dl_load_balance;
+      uint16_t flr_time_out;
+  };
+
+- ``pf_mode_en``: identifies whether only PF is to be used, or the VFs. PF and
+  VFs are mutually exclusive and cannot run simultaneously.
+  Set to 1 for PF mode enabled.
+  If PF mode is enabled all queues available in the device are assigned
+  exclusively to PF and 0 queues given to VFs.
+
+- ``vf_*l_queues_number``: defines the hardware queue mapping for every VF.
+
+- ``*l_bandwidth``: in case of congestion on PCIe interface. The device
+  allocates different bandwidth to UL and DL. The weight is configured by this
+  setting. The unit of weight is 3 code blocks. For example, if the code block
+  cbps (code block per second) ratio between UL and DL is 12:1, then the
+  configuration value should be set to 36:3. The schedule algorithm is based
+  on code block regardless the length of each block.
+
+- ``*l_load_balance``: hardware queues are load-balanced in a round-robin
+  fashion. Queues get filled first-in first-out until they reach a pre-defined
+  watermark level, if exceeded, they won't get assigned new code blocks..
+  This watermark is defined by this setting.
+
+  If all hardware queues exceeds the watermark, no code blocks will be
+  streamed in from UL/DL code block FIFO.
+
+- ``flr_time_out``: specifies how many 16.384us to be FLR time out. The
+  time_out = flr_time_out x 16.384us. For instance, if you want to set 10ms for
+  the FLR time out then set this setting to 0x262=610.
+
+
+An example configuration code calling the function ``fpga_lte_fec_configure()`` is shown
+below:
+
+.. code-block:: c
+
+  struct fpga_lte_fec_conf conf;
+  unsigned int i;
+
+  memset(&conf, 0, sizeof(struct fpga_lte_fec_conf));
+  conf.pf_mode_en = 1;
+
+  for (i = 0; i < FPGA_LTE_FEC_NUM_VFS; ++i) {
+      conf.vf_ul_queues_number[i] = 4;
+      conf.vf_dl_queues_number[i] = 4;
+  }
+  conf.ul_bandwidth = 12;
+  conf.dl_bandwidth = 5;
+  conf.dl_load_balance = 64;
+  conf.ul_load_balance = 64;
+
+  /* setup FPGA PF */
+  ret = fpga_lte_fec_configure(info->dev_name, &conf);
+  TEST_ASSERT_SUCCESS(ret,
+      "Failed to configure 4G FPGA PF for bbdev %s",
+      info->dev_name);
+
+
+Test Application
+----------------
+
+BBDEV provides a test application, ``test-bbdev.py`` and range of test data for testing
+the functionality of FPGA LTE FEC turbo encode and turbo decode, 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 (default=dpdk_path+/app/test-bbdev/test_vectors/bbdev_null.data).
+  "-n", "--num-ops"	: Number of operations to process on device (default=32).
+  "-b", "--burst-size"	: Operations enqueue/dequeue burst size (default=32).
+  "-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 turbo decode or turbo encode data,
+type one of the following:
+
+.. code-block:: console
+
+  ./test-bbdev.py -c validation -n 64 -b 8 -v ./turbo_dec_default.data
+  ./test-bbdev.py -c validation -n 64 -b 8 -v ./turbo_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 as:
+
+- VF_UL_QUEUE_VALUE 4
+- VF_DL_QUEUE_VALUE 4
+- UL_BANDWIDTH 3
+- DL_BANDWIDTH 3
+- UL_LOAD_BALANCE 128
+- DL_LOAD_BALANCE 128
+- FLR_TIMEOUT 610
+
+
+Test Vectors
+~~~~~~~~~~~~
+
+In addition to the simple turbo decoder and turbo 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 FPGA LTE FEC capabilities:
+
+* turbo decoder tests:
+   - ``turbo_dec_c1_k6144_r0_e10376_crc24b_sbd_negllr_high_snr.data``
+   - ``turbo_dec_c1_k6144_r0_e10376_crc24b_sbd_negllr_low_snr.data``
+   - ``turbo_dec_c1_k6144_r0_e34560_negllr.data``
+   - ``turbo_dec_c1_k6144_r0_e34560_sbd_negllr.data``
+   - ``turbo_dec_c2_k3136_r0_e4920_sbd_negllr_crc24b.data``
+   - ``turbo_dec_c2_k3136_r0_e4920_sbd_negllr.data``
+
+
+* turbo encoder tests:
+   - ``turbo_enc_c1_k40_r0_e1190_rm.data``
+   - ``turbo_enc_c1_k40_r0_e1194_rm.data``
+   - ``turbo_enc_c1_k40_r0_e1196_rm.data``
+   - ``turbo_enc_c1_k40_r0_e272_rm.data``

[dpdk-dev] [PATCH v4] baseband/fpga_lte_fec: adding driver for FEC on FPGA

[Nicolas Chautru]

Update v4: Fix warning for the DEBUG configuration
Update v3: Squashing 3 previous patches into one as recommended.  

This is adding a new PMD driver for BBDEV device based on FPGA implementation on PAC N3000 HW to provide FEC 4G acceleration. 
v1 was shared earlier on this patchwork :
https://patches.dpdk.org/patch/53409/
The existing BBDEV test framework is still supported. 

Main updates based on feedback during the last v1 were:
- correct the documentation which was arguably misleading in hinting that ICC was required. There is no dependency whatsoever. 
- add meson build support

Note that a number of other BBDEV patches are in v1 here and will be resubmitted for 19.08 rc1
https://patches.dpdk.org/project/dpdk/list/?series=4657

+Intel(R) FPGA LTE FEC Poll Mode Driver
+======================================
+
+The BBDEV FPGA LTE FEC poll mode driver (PMD) supports an FPGA implementation of a VRAN
+Turbo Encode / Decode LTE wireless acceleration function, using Intel's PCI-e and FPGA
+based Vista Creek device.
+
+Features
+--------
+
+FPGA LTE FEC PMD supports the following features:
+
+- Turbo Encode in the DL with total throughput of 4.5 Gbits/s
+- Turbo Decode in the UL with total throughput of 1.5 Gbits/s assuming 8 decoder iterations
+- 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
+
+
+FPGA LTE FEC PMD supports the following BBDEV capabilities:
+
+* For the turbo encode operation:
+   - ``RTE_BBDEV_TURBO_CRC_24B_ATTACH`` :  set to attach CRC24B to CB(s)
+   - ``RTE_BBDEV_TURBO_RATE_MATCH`` :  if set then do not do Rate Match bypass
+   - ``RTE_BBDEV_TURBO_ENC_INTERRUPTS`` :  set for encoder dequeue interrupts
+
+
+* For the turbo decode operation:
+   - ``RTE_BBDEV_TURBO_CRC_TYPE_24B`` :  check CRC24B from CB(s)
+   - ``RTE_BBDEV_TURBO_SUBBLOCK_DEINTERLEAVE`` :  perform subblock de-interleave

+Limitations
+-----------
+
+FPGA LTE 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 LTE FEC device, ``CONFIG_RTE_LIBRTE_PMD_FPGA_LTE_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 -vd1172:5052
+
+The physical and virtual functions are compatible with Linux UIO drivers:
+``vfio`` and ``igb_uio``. However, in order to work the FPGA LTE 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 "1172 5052" > /sys/bus/pci/drivers/igb_uio/new_id
+  lspci -vd1172:
+
+
+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 -vd1172:
+
+
+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 LTE 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
+
+
+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 function ``fpga_lte_fec_configure()``, which sets up the
+parameters defined in ``fpga_lte_fec_conf`` structure:
+
+.. code-block:: c
+
+  struct fpga_lte_fec_conf {
+      bool pf_mode_en;
+      uint8_t vf_ul_queues_number[FPGA_LTE_FEC_NUM_VFS];
+      uint8_t vf_dl_queues_number[FPGA_LTE_FEC_NUM_VFS];
+      uint8_t ul_bandwidth;
+      uint8_t dl_bandwidth;
+      uint8_t ul_load_balance;
+      uint8_t dl_load_balance;
+      uint16_t flr_time_out;
+  };
+
+- ``pf_mode_en``: identifies whether only PF is to be used, or the VFs. PF and
+  VFs are mutually exclusive and cannot run simultaneously.
+  Set to 1 for PF mode enabled.
+  If PF mode is enabled all queues available in the device are assigned
+  exclusively to PF and 0 queues given to VFs.
+
+- ``vf_*l_queues_number``: defines the hardware queue mapping for every VF.
+
+- ``*l_bandwidth``: in case of congestion on PCIe interface. The device
+  allocates different bandwidth to UL and DL. The weight is configured by this
+  setting. The unit of weight is 3 code blocks. For example, if the code block
+  cbps (code block per second) ratio between UL and DL is 12:1, then the
+  configuration value should be set to 36:3. The schedule algorithm is based
+  on code block regardless the length of each block.
+
+- ``*l_load_balance``: hardware queues are load-balanced in a round-robin
+  fashion. Queues get filled first-in first-out until they reach a pre-defined
+  watermark level, if exceeded, they won't get assigned new code blocks..
+  This watermark is defined by this setting.
+
+  If all hardware queues exceeds the watermark, no code blocks will be
+  streamed in from UL/DL code block FIFO.
+
+- ``flr_time_out``: specifies how many 16.384us to be FLR time out. The
+  time_out = flr_time_out x 16.384us. For instance, if you want to set 10ms for
+  the FLR time out then set this setting to 0x262=610.
+
+
+An example configuration code calling the function ``fpga_lte_fec_configure()`` is shown
+below:
+
+.. code-block:: c
+
+  struct fpga_lte_fec_conf conf;
+  unsigned int i;
+
+  memset(&conf, 0, sizeof(struct fpga_lte_fec_conf));
+  conf.pf_mode_en = 1;
+
+  for (i = 0; i < FPGA_LTE_FEC_NUM_VFS; ++i) {
+      conf.vf_ul_queues_number[i] = 4;
+      conf.vf_dl_queues_number[i] = 4;
+  }
+  conf.ul_bandwidth = 12;
+  conf.dl_bandwidth = 5;
+  conf.dl_load_balance = 64;
+  conf.ul_load_balance = 64;
+
+  /* setup FPGA PF */
+  ret = fpga_lte_fec_configure(info->dev_name, &conf);
+  TEST_ASSERT_SUCCESS(ret,
+      "Failed to configure 4G FPGA PF for bbdev %s",
+      info->dev_name);
+
+
+Test Application
+----------------
+
+BBDEV provides a test application, ``test-bbdev.py`` and range of test data for testing
+the functionality of FPGA LTE FEC turbo encode and turbo decode, 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 (default=dpdk_path+/app/test-bbdev/test_vectors/bbdev_null.data).
+  "-n", "--num-ops"	: Number of operations to process on device (default=32).
+  "-b", "--burst-size"	: Operations enqueue/dequeue burst size (default=32).
+  "-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 turbo decode or turbo encode data,
+type one of the following:
+
+.. code-block:: console
+
+  ./test-bbdev.py -c validation -n 64 -b 8 -v ./turbo_dec_default.data
+  ./test-bbdev.py -c validation -n 64 -b 8 -v ./turbo_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 as:
+
+- VF_UL_QUEUE_VALUE 4
+- VF_DL_QUEUE_VALUE 4
+- UL_BANDWIDTH 3
+- DL_BANDWIDTH 3
+- UL_LOAD_BALANCE 128
+- DL_LOAD_BALANCE 128
+- FLR_TIMEOUT 610
+
+
+Test Vectors
+~~~~~~~~~~~~
+
+In addition to the simple turbo decoder and turbo 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 FPGA LTE FEC capabilities:
+
+* turbo decoder tests:
+   - ``turbo_dec_c1_k6144_r0_e10376_crc24b_sbd_negllr_high_snr.data``
+   - ``turbo_dec_c1_k6144_r0_e10376_crc24b_sbd_negllr_low_snr.data``
+   - ``turbo_dec_c1_k6144_r0_e34560_negllr.data``
+   - ``turbo_dec_c1_k6144_r0_e34560_sbd_negllr.data``
+   - ``turbo_dec_c2_k3136_r0_e4920_sbd_negllr_crc24b.data``
+   - ``turbo_dec_c2_k3136_r0_e4920_sbd_negllr.data``
+
+
+* turbo encoder tests:
+   - ``turbo_enc_c1_k40_r0_e1190_rm.data``
+   - ``turbo_enc_c1_k40_r0_e1194_rm.data``
+   - ``turbo_enc_c1_k40_r0_e1196_rm.data``
+   - ``turbo_enc_c1_k40_r0_e272_rm.data``
+   - ``turbo_enc_c1_k6144_r0_e18444.data``
+   - ``turbo_enc_c1_k6144_r0_e32256_crc24b_rm.data``
+   - ``turbo_enc_c2_k5952_r0_e17868_crc24b.data``
+   - ``turbo_enc_c3_k4800_r2_e14412_crc24b.data``

[dpdk-dev] [PATCH v4] baseband/fpga_lte_fec: adding driver for FEC on FPGA

[Nicolas Chautru]

Update v4: Fix warning for the DEBUG configuration.
Update v3: Squashing 3 previous patches into one as recommended.  

This is adding a new PMD driver for BBDEV device based on FPGA implementation on PAC N3000 HW to provide FEC 4G acceleration. 
v1 was shared earlier on this patchwork :
https://patches.dpdk.org/patch/53409/
The existing BBDEV test framework is still supported. 

Main updates based on feedback during the last v1 were:
- correct the documentation which was arguably misleading in hinting that ICC was required. There is no dependency whatsoever. 
- add meson build support

Note that a number of other BBDEV patches are in v1 here and will be resubmitted for 19.08 rc1
https://patches.dpdk.org/project/dpdk/list/?series=4657

+Intel(R) FPGA LTE FEC Poll Mode Driver
+======================================
+
+The BBDEV FPGA LTE FEC poll mode driver (PMD) supports an FPGA implementation of a VRAN
+Turbo Encode / Decode LTE wireless acceleration function, using Intel's PCI-e and FPGA
+based Vista Creek device.
+
+Features
+--------
+
+FPGA LTE FEC PMD supports the following features:
+
+- Turbo Encode in the DL with total throughput of 4.5 Gbits/s
+- Turbo Decode in the UL with total throughput of 1.5 Gbits/s assuming 8 decoder iterations
+- 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
+
+
+FPGA LTE FEC PMD supports the following BBDEV capabilities:
+
+* For the turbo encode operation:
+   - ``RTE_BBDEV_TURBO_CRC_24B_ATTACH`` :  set to attach CRC24B to CB(s)
+   - ``RTE_BBDEV_TURBO_RATE_MATCH`` :  if set then do not do Rate Match bypass
+   - ``RTE_BBDEV_TURBO_ENC_INTERRUPTS`` :  set for encoder dequeue interrupts
+
+
+* For the turbo decode operation:
+   - ``RTE_BBDEV_TURBO_CRC_TYPE_24B`` :  check CRC24B from CB(s)
+   - ``RTE_BBDEV_TURBO_SUBBLOCK_DEINTERLEAVE`` :  perform subblock de-interleave
+   - ``RTE_BBDEV_TURBO_DEC_INTERRUPTS`` :  set for decoder dequeue interrupts
+   - ``RTE_BBDEV_TURBO_NEG_LLR_1_BIT_IN`` :  set if negative LLR encoder i/p is supported
+   - ``RTE_BBDEV_TURBO_DEC_TB_CRC_24B_KEEP`` :  keep CRC24B bits appended while decoding
+
+
+Limitations
+-----------
+
+FPGA LTE 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 LTE FEC device, ``CONFIG_RTE_LIBRTE_PMD_FPGA_LTE_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 -vd1172:5052
+
+The physical and virtual functions are compatible with Linux UIO drivers:
+``vfio`` and ``igb_uio``. However, in order to work the FPGA LTE 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 "1172 5052" > /sys/bus/pci/drivers/igb_uio/new_id
+  lspci -vd1172:
+
+
+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 -vd1172:
+
+
+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 LTE 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
+
+
+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 function ``fpga_lte_fec_configure()``, which sets up the
+parameters defined in ``fpga_lte_fec_conf`` structure:
+
+.. code-block:: c
+
+  struct fpga_lte_fec_conf {
+      bool pf_mode_en;
+      uint8_t vf_ul_queues_number[FPGA_LTE_FEC_NUM_VFS];
+      uint8_t vf_dl_queues_number[FPGA_LTE_FEC_NUM_VFS];
+      uint8_t ul_bandwidth;
+      uint8_t dl_bandwidth;
+      uint8_t ul_load_balance;
+      uint8_t dl_load_balance;
+      uint16_t flr_time_out;
+  };
+
+- ``pf_mode_en``: identifies whether only PF is to be used, or the VFs. PF and
+  VFs are mutually exclusive and cannot run simultaneously.
+  Set to 1 for PF mode enabled.
+  If PF mode is enabled all queues available in the device are assigned
+  exclusively to PF and 0 queues given to VFs.
+
+- ``vf_*l_queues_number``: defines the hardware queue mapping for every VF.
+
+- ``*l_bandwidth``: in case of congestion on PCIe interface. The device
+  allocates different bandwidth to UL and DL. The weight is configured by this
+  setting. The unit of weight is 3 code blocks. For example, if the code block
+  cbps (code block per second) ratio between UL and DL is 12:1, then the
+  configuration value should be set to 36:3. The schedule algorithm is based
+  on code block regardless the length of each block.
+
+- ``*l_load_balance``: hardware queues are load-balanced in a round-robin
+  fashion. Queues get filled first-in first-out until they reach a pre-defined
+  watermark level, if exceeded, they won't get assigned new code blocks..
+  This watermark is defined by this setting.
+
+  If all hardware queues exceeds the watermark, no code blocks will be
+  streamed in from UL/DL code block FIFO.
+
+- ``flr_time_out``: specifies how many 16.384us to be FLR time out. The
+  time_out = flr_time_out x 16.384us. For instance, if you want to set 10ms for
+  the FLR time out then set this setting to 0x262=610.
+
+
+An example configuration code calling the function ``fpga_lte_fec_configure()`` is shown
+below:
+
+.. code-block:: c
+
+  struct fpga_lte_fec_conf conf;
+  unsigned int i;
+
+  memset(&conf, 0, sizeof(struct fpga_lte_fec_conf));

+      conf.vf_ul_queues_number[i] = 4;
+      conf.vf_dl_queues_number[i] = 4;
+  }
+  conf.ul_bandwidth = 12;
+  conf.dl_bandwidth = 5;
+  conf.dl_load_balance = 64;
+  conf.ul_load_balance = 64;
+
+  /* setup FPGA PF */
+  ret = fpga_lte_fec_configure(info->dev_name, &conf);

+      info->dev_name);
+
+
+Test Application
+----------------
+
+BBDEV provides a test application, ``test-bbdev.py`` and range of test data for testing
+the functionality of FPGA LTE FEC turbo encode and turbo decode, 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 (default=dpdk_path+/app/test-bbdev/test_vectors/bbdev_null.data).
+  "-n", "--num-ops"	: Number of operations to process on device (default=32).
+  "-b", "--burst-size"	: Operations enqueue/dequeue burst size (default=32).
+  "-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 turbo decode or turbo encode data,
+type one of the following:
+
+.. code-block:: console
+
+  ./test-bbdev.py -c validation -n 64 -b 8 -v ./turbo_dec_default.data
+  ./test-bbdev.py -c validation -n 64 -b 8 -v ./turbo_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 as:
+
+- VF_UL_QUEUE_VALUE 4
+- VF_DL_QUEUE_VALUE 4
+- UL_BANDWIDTH 3
+- DL_BANDWIDTH 3
+- UL_LOAD_BALANCE 128
+- DL_LOAD_BALANCE 128
+- FLR_TIMEOUT 610
+
+
+Test Vectors
+~~~~~~~~~~~~
+
+In addition to the simple turbo decoder and turbo 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 FPGA LTE FEC capabilities:
+
+* turbo decoder tests:
+   - ``turbo_dec_c1_k6144_r0_e10376_crc24b_sbd_negllr_high_snr.data``
+   - ``turbo_dec_c1_k6144_r0_e10376_crc24b_sbd_negllr_low_snr.data``
+   - ``turbo_dec_c1_k6144_r0_e34560_negllr.data``
+   - ``turbo_dec_c1_k6144_r0_e34560_sbd_negllr.data``
+   - ``turbo_dec_c2_k3136_r0_e4920_sbd_negllr_crc24b.data``
+   - ``turbo_dec_c2_k3136_r0_e4920_sbd_negllr.data``
+
+
+* turbo encoder tests:
+   - ``turbo_enc_c1_k40_r0_e1190_rm.data``
+   - ``turbo_enc_c1_k40_r0_e1194_rm.data``
+   - ``turbo_enc_c1_k40_r0_e1196_rm.data``
+   - ``turbo_enc_c1_k40_r0_e272_rm.data``
+   - ``turbo_enc_c1_k6144_r0_e18444.data``
+   - ``turbo_enc_c1_k6144_r0_e32256_crc24b_rm.data``
+   - ``turbo_enc_c2_k5952_r0_e17868_crc24b.data``
+   - ``turbo_enc_c3_k4800_r2_e14412_crc24b.data``

We discussed in parallel that the driver is not meant to catch all user
errors condition even in debug mode. We agreed that this was not required but thanks

[dpdk-dev] [PATCH v5] baseband/fpga_lte_fec: adding driver for FEC on FPGA

[Nicolas Chautru]

Update v5: Update date and version from dpdk review. Rebased to latest. 
Update v4: Fix warning for the DEBUG configuration.
Update v3: Squashing 3 previous patches into one as recommended.  

This is adding a new PMD driver for BBDEV device based on FPGA implementation on PAC N3000 HW to provide FEC 4G acceleration. 
v1 was shared earlier on this patchwork :
https://patches.dpdk.org/patch/53409/
The existing BBDEV test framework is still supported. 

Main updates based on feedback during the last v1 were:
- correct the documentation which was arguably misleading in hinting that ICC was required. There is no dependency whatsoever. 
- add meson build support

Note that a number of other BBDEV patches are in v1 here and will be resubmitted for 19.08 rc1
https://patches.dpdk.org/project/dpdk/list/?series=4657

+Intel(R) FPGA LTE FEC Poll Mode Driver
+======================================
+
+The BBDEV FPGA LTE FEC poll mode driver (PMD) supports an FPGA implementation of a VRAN
+Turbo Encode / Decode LTE wireless acceleration function, using Intel's PCI-e and FPGA
+based Vista Creek device.
+
+Features
+--------
+
+FPGA LTE FEC PMD supports the following features:
+
+- Turbo Encode in the DL with total throughput of 4.5 Gbits/s
+- Turbo Decode in the UL with total throughput of 1.5 Gbits/s assuming 8 decoder iterations
+- 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
+
+
+FPGA LTE FEC PMD supports the following BBDEV capabilities:
+
+* For the turbo encode operation:
+   - ``RTE_BBDEV_TURBO_CRC_24B_ATTACH`` :  set to attach CRC24B to CB(s)
+   - ``RTE_BBDEV_TURBO_RATE_MATCH`` :  if set then do not do Rate Match bypass
+   - ``RTE_BBDEV_TURBO_ENC_INTERRUPTS`` :  set for encoder dequeue interrupts
+
+
+* For the turbo decode operation:
+   - ``RTE_BBDEV_TURBO_CRC_TYPE_24B`` :  check CRC24B from CB(s)
+   - ``RTE_BBDEV_TURBO_SUBBLOCK_DEINTERLEAVE`` :  perform subblock de-interleave
+   - ``RTE_BBDEV_TURBO_DEC_INTERRUPTS`` :  set for decoder dequeue interrupts
+   - ``RTE_BBDEV_TURBO_NEG_LLR_1_BIT_IN`` :  set if negative LLR encoder i/p is supported
+   - ``RTE_BBDEV_TURBO_DEC_TB_CRC_24B_KEEP`` :  keep CRC24B bits appended while decoding
+
+
+Limitations
+-----------
+
+FPGA LTE 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 LTE FEC device, ``CONFIG_RTE_LIBRTE_PMD_FPGA_LTE_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 -vd1172:5052
+
+The physical and virtual functions are compatible with Linux UIO drivers:
+``vfio`` and ``igb_uio``. However, in order to work the FPGA LTE 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 "1172 5052" > /sys/bus/pci/drivers/igb_uio/new_id
+  lspci -vd1172:
+
+
+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 -vd1172:
+
+
+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 LTE 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
+
+
+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 function ``fpga_lte_fec_configure()``, which sets up the
+parameters defined in ``fpga_lte_fec_conf`` structure:
+
+.. code-block:: c
+
+  struct fpga_lte_fec_conf {
+      bool pf_mode_en;
+      uint8_t vf_ul_queues_number[FPGA_LTE_FEC_NUM_VFS];
+      uint8_t vf_dl_queues_number[FPGA_LTE_FEC_NUM_VFS];
+      uint8_t ul_bandwidth;
+      uint8_t dl_bandwidth;
+      uint8_t ul_load_balance;
+      uint8_t dl_load_balance;
+      uint16_t flr_time_out;
+  };
+
+- ``pf_mode_en``: identifies whether only PF is to be used, or the VFs. PF and
+  VFs are mutually exclusive and cannot run simultaneously.
+  Set to 1 for PF mode enabled.
+  If PF mode is enabled all queues available in the device are assigned
+  exclusively to PF and 0 queues given to VFs.
+
+- ``vf_*l_queues_number``: defines the hardware queue mapping for every VF.
+
+- ``*l_bandwidth``: in case of congestion on PCIe interface. The device
+  allocates different bandwidth to UL and DL. The weight is configured by this
+  setting. The unit of weight is 3 code blocks. For example, if the code block
+  cbps (code block per second) ratio between UL and DL is 12:1, then the
+  configuration value should be set to 36:3. The schedule algorithm is based
+  on code block regardless the length of each block.
+
+- ``*l_load_balance``: hardware queues are load-balanced in a round-robin
+  fashion. Queues get filled first-in first-out until they reach a pre-defined
+  watermark level, if exceeded, they won't get assigned new code blocks..
+  This watermark is defined by this setting.
+
+  If all hardware queues exceeds the watermark, no code blocks will be
+  streamed in from UL/DL code block FIFO.
+
+- ``flr_time_out``: specifies how many 16.384us to be FLR time out. The
+  time_out = flr_time_out x 16.384us. For instance, if you want to set 10ms for
+  the FLR time out then set this setting to 0x262=610.
+
+
+An example configuration code calling the function ``fpga_lte_fec_configure()`` is shown
+below:
+
+.. code-block:: c
+
+  struct fpga_lte_fec_conf conf;
+  unsigned int i;
+
+  memset(&conf, 0, sizeof(struct fpga_lte_fec_conf));
+  conf.pf_mode_en = 1;
+
+  for (i = 0; i < FPGA_LTE_FEC_NUM_VFS; ++i) {
+      conf.vf_ul_queues_number[i] = 4;
+      conf.vf_dl_queues_number[i] = 4;
+  }
+  conf.ul_bandwidth = 12;
+  conf.dl_bandwidth = 5;
+  conf.dl_load_balance = 64;
+  conf.ul_load_balance = 64;
+
+  /* setup FPGA PF */
+  ret = fpga_lte_fec_configure(info->dev_name, &conf);
+  TEST_ASSERT_SUCCESS(ret,
+      "Failed to configure 4G FPGA PF for bbdev %s",
+      info->dev_name);
+
+
+Test Application
+----------------
+
+BBDEV provides a test application, ``test-bbdev.py`` and range of test data for testing
+the functionality of FPGA LTE FEC turbo encode and turbo decode, 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 (default=dpdk_path+/app/test-bbdev/test_vectors/bbdev_null.data).
+  "-n", "--num-ops"	: Number of operations to process on device (default=32).
+  "-b", "--burst-size"	: Operations enqueue/dequeue burst size (default=32).
+  "-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 turbo decode or turbo encode data,
+type one of the following:
+
+.. code-block:: console
+
+  ./test-bbdev.py -c validation -n 64 -b 8 -v ./turbo_dec_default.data
+  ./test-bbdev.py -c validation -n 64 -b 8 -v ./turbo_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 as:
+
+- VF_UL_QUEUE_VALUE 4
+- VF_DL_QUEUE_VALUE 4
+- UL_BANDWIDTH 3
+- DL_BANDWIDTH 3
+- UL_LOAD_BALANCE 128
+- DL_LOAD_BALANCE 128
+- FLR_TIMEOUT 610
+
+
+Test Vectors
+~~~~~~~~~~~~
+
+In addition to the simple turbo decoder and turbo 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 FPGA LTE FEC capabilities:
+
+* turbo decoder tests:
+   - ``turbo_dec_c1_k6144_r0_e10376_crc24b_sbd_negllr_high_snr.data``

+   - ``turbo_dec_c2_k3136_r0_e4920_sbd_negllr.data``
+
+
+* turbo encoder tests:
+   - ``turbo_enc_c1_k40_r0_e1190_rm.data``

[dpdk-dev] [PATCH v6] baseband/fpga_lte_fec: adding driver for FEC on FPGA

[Nicolas Chautru]

Update v6: Update of one copyright date in documentation file.
Update v5: Update date and version from dpdk review. Rebased to latest. 
Update v4: Fix warning for the DEBUG configuration.
Update v3: Squashing 3 previous patches into one as recommended.  

This is adding a new PMD driver for BBDEV device based on FPGA implementation on PAC N3000 HW to provide FEC 4G acceleration. 
v1 was shared earlier on this patchwork :
https://patches.dpdk.org/patch/53409/
The existing BBDEV test framework is still supported. 

Main updates based on feedback during the last v1 were:
- correct the documentation which was arguably misleading in hinting that ICC was required. There is no dependency whatsoever. 
- add meson build support

Note that a number of other BBDEV patches are in v1 here and will be resubmitted for 19.08 rc1

+Intel(R) FPGA LTE FEC Poll Mode Driver
+======================================
+
+The BBDEV FPGA LTE FEC poll mode driver (PMD) supports an FPGA implementation of a VRAN
+Turbo Encode / Decode LTE wireless acceleration function, using Intel's PCI-e and FPGA
+based Vista Creek device.
+
+Features
+--------
+
+FPGA LTE FEC PMD supports the following features:
+
+- Turbo Encode in the DL with total throughput of 4.5 Gbits/s
+- Turbo Decode in the UL with total throughput of 1.5 Gbits/s assuming 8 decoder iterations
+- 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
+
+
+FPGA LTE FEC PMD supports the following BBDEV capabilities:
+
+* For the turbo encode operation:
+   - ``RTE_BBDEV_TURBO_CRC_24B_ATTACH`` :  set to attach CRC24B to CB(s)
+   - ``RTE_BBDEV_TURBO_RATE_MATCH`` :  if set then do not do Rate Match bypass
+   - ``RTE_BBDEV_TURBO_ENC_INTERRUPTS`` :  set for encoder dequeue interrupts
+
+
+* For the turbo decode operation:
+   - ``RTE_BBDEV_TURBO_CRC_TYPE_24B`` :  check CRC24B from CB(s)
+   - ``RTE_BBDEV_TURBO_SUBBLOCK_DEINTERLEAVE`` :  perform subblock de-interleave
+   - ``RTE_BBDEV_TURBO_DEC_INTERRUPTS`` :  set for decoder dequeue interrupts
+   - ``RTE_BBDEV_TURBO_NEG_LLR_1_BIT_IN`` :  set if negative LLR encoder i/p is supported
+   - ``RTE_BBDEV_TURBO_DEC_TB_CRC_24B_KEEP`` :  keep CRC24B bits appended while decoding
+
+
+Limitations
+-----------
+
+FPGA LTE 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 LTE FEC device, ``CONFIG_RTE_LIBRTE_PMD_FPGA_LTE_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 -vd1172:5052
+
+The physical and virtual functions are compatible with Linux UIO drivers:
+``vfio`` and ``igb_uio``. However, in order to work the FPGA LTE 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 "1172 5052" > /sys/bus/pci/drivers/igb_uio/new_id
+  lspci -vd1172:
+
+
+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 -vd1172:
+
+
+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 LTE 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
+
+
+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 function ``fpga_lte_fec_configure()``, which sets up the
+parameters defined in ``fpga_lte_fec_conf`` structure:
+
+.. code-block:: c
+
+  struct fpga_lte_fec_conf {
+      bool pf_mode_en;
+      uint8_t vf_ul_queues_number[FPGA_LTE_FEC_NUM_VFS];
+      uint8_t vf_dl_queues_number[FPGA_LTE_FEC_NUM_VFS];
+      uint8_t ul_bandwidth;
+      uint8_t dl_bandwidth;
+      uint8_t ul_load_balance;
+      uint8_t dl_load_balance;
+      uint16_t flr_time_out;
+  };
+
+- ``pf_mode_en``: identifies whether only PF is to be used, or the VFs. PF and
+  VFs are mutually exclusive and cannot run simultaneously.
+  Set to 1 for PF mode enabled.
+  If PF mode is enabled all queues available in the device are assigned
+  exclusively to PF and 0 queues given to VFs.
+
+- ``vf_*l_queues_number``: defines the hardware queue mapping for every VF.
+
+- ``*l_bandwidth``: in case of congestion on PCIe interface. The device
+  allocates different bandwidth to UL and DL. The weight is configured by this
+  setting. The unit of weight is 3 code blocks. For example, if the code block
+  cbps (code block per second) ratio between UL and DL is 12:1, then the
+  configuration value should be set to 36:3. The schedule algorithm is based
+  on code block regardless the length of each block.
+
+- ``*l_load_balance``: hardware queues are load-balanced in a round-robin
+  fashion. Queues get filled first-in first-out until they reach a pre-defined
+  watermark level, if exceeded, they won't get assigned new code blocks..
+  This watermark is defined by this setting.
+
+  If all hardware queues exceeds the watermark, no code blocks will be
+  streamed in from UL/DL code block FIFO.
+
+- ``flr_time_out``: specifies how many 16.384us to be FLR time out. The
+  time_out = flr_time_out x 16.384us. For instance, if you want to set 10ms for
+  the FLR time out then set this setting to 0x262=610.
+
+
+An example configuration code calling the function ``fpga_lte_fec_configure()`` is shown
+below:
+
+.. code-block:: c
+
+  struct fpga_lte_fec_conf conf;
+  unsigned int i;
+
+  memset(&conf, 0, sizeof(struct fpga_lte_fec_conf));
+  conf.pf_mode_en = 1;
+
+  for (i = 0; i < FPGA_LTE_FEC_NUM_VFS; ++i) {
+      conf.vf_ul_queues_number[i] = 4;
+      conf.vf_dl_queues_number[i] = 4;
+  }
+  conf.ul_bandwidth = 12;
+  conf.dl_bandwidth = 5;
+  conf.dl_load_balance = 64;
+  conf.ul_load_balance = 64;
+
+  /* setup FPGA PF */
+  ret = fpga_lte_fec_configure(info->dev_name, &conf);
+  TEST_ASSERT_SUCCESS(ret,
+      "Failed to configure 4G FPGA PF for bbdev %s",
+      info->dev_name);
+
+
+Test Application
+----------------
+
+BBDEV provides a test application, ``test-bbdev.py`` and range of test data for testing
+the functionality of FPGA LTE FEC turbo encode and turbo decode, 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 (default=dpdk_path+/app/test-bbdev/test_vectors/bbdev_null.data).
+  "-n", "--num-ops"	: Number of operations to process on device (default=32).
+  "-b", "--burst-size"	: Operations enqueue/dequeue burst size (default=32).
+  "-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 turbo decode or turbo encode data,
+type one of the following:
+
+.. code-block:: console
+
+  ./test-bbdev.py -c validation -n 64 -b 8 -v ./turbo_dec_default.data
+  ./test-bbdev.py -c validation -n 64 -b 8 -v ./turbo_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 as:
+
+- VF_UL_QUEUE_VALUE 4
+- VF_DL_QUEUE_VALUE 4
+- UL_BANDWIDTH 3
+- DL_BANDWIDTH 3
+- UL_LOAD_BALANCE 128
+- DL_LOAD_BALANCE 128
+- FLR_TIMEOUT 610
+
+
+Test Vectors
+~~~~~~~~~~~~
+
+In addition to the simple turbo decoder and turbo 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 FPGA LTE FEC capabilities:
+
+* turbo decoder tests:
+   - ``turbo_dec_c1_k6144_r0_e10376_crc24b_sbd_negllr_high_snr.data``
+   - ``turbo_dec_c1_k6144_r0_e10376_crc24b_sbd_negllr_low_snr.data``
+   - ``turbo_dec_c1_k6144_r0_e34560_negllr.data``
+   - ``turbo_dec_c1_k6144_r0_e34560_sbd_negllr.data``
+   - ``turbo_dec_c2_k3136_r0_e4920_sbd_negllr_crc24b.data``
+   - ``turbo_dec_c2_k3136_r0_e4920_sbd_negllr.data``
+
+
+* turbo encoder tests:
+   - ``turbo_enc_c1_k40_r0_e1190_rm.data``
+   - ``turbo_enc_c1_k40_r0_e1194_rm.data``
+   - ``turbo_enc_c1_k40_r0_e1196_rm.data``

[dpdk-dev] [PATCH v6] baseband/fpga_lte_fec: adding driver for FEC on FPGA

[Nicolas Chautru]

Update v6: Update of one copyright date in documentation file.
Update v5: Update date and version from dpdk review. Rebased to latest. 
Update v4: Fix warning for the DEBUG configuration.
Update v3: Squashing 3 previous patches into one as recommended.  

This is adding a new PMD driver for BBDEV device based on FPGA implementation on PAC N3000 HW to provide FEC 4G acceleration. 
v1 was shared earlier on this patchwork :
https://patches.dpdk.org/patch/53409/
The existing BBDEV test framework is still supported. 

Main updates based on feedback during the last v1 were:
- correct the documentation which was arguably misleading in hinting that ICC was required. There is no dependency whatsoever. 
- add meson build support

Note that a number of other BBDEV patches are in v1 here and will be resubmitted for 19.08 rc1
https://patches.dpdk.org/project/dpdk/list/?series=4657

+Intel(R) FPGA LTE FEC Poll Mode Driver
+======================================
+
+The BBDEV FPGA LTE FEC poll mode driver (PMD) supports an FPGA implementation of a VRAN
+Turbo Encode / Decode LTE wireless acceleration function, using Intel's PCI-e and FPGA
+based Vista Creek device.
+
+Features
+--------
+
+FPGA LTE FEC PMD supports the following features:
+
+- Turbo Encode in the DL with total throughput of 4.5 Gbits/s
+- Turbo Decode in the UL with total throughput of 1.5 Gbits/s assuming 8 decoder iterations
+- 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
+
+
+FPGA LTE FEC PMD supports the following BBDEV capabilities:
+
+* For the turbo encode operation:
+   - ``RTE_BBDEV_TURBO_CRC_24B_ATTACH`` :  set to attach CRC24B to CB(s)
+   - ``RTE_BBDEV_TURBO_RATE_MATCH`` :  if set then do not do Rate Match bypass
+   - ``RTE_BBDEV_TURBO_ENC_INTERRUPTS`` :  set for encoder dequeue interrupts
+
+
+* For the turbo decode operation:
+   - ``RTE_BBDEV_TURBO_CRC_TYPE_24B`` :  check CRC24B from CB(s)
+   - ``RTE_BBDEV_TURBO_SUBBLOCK_DEINTERLEAVE`` :  perform subblock de-interleave
+   - ``RTE_BBDEV_TURBO_DEC_INTERRUPTS`` :  set for decoder dequeue interrupts
+   - ``RTE_BBDEV_TURBO_NEG_LLR_1_BIT_IN`` :  set if negative LLR encoder i/p is supported
+   - ``RTE_BBDEV_TURBO_DEC_TB_CRC_24B_KEEP`` :  keep CRC24B bits appended while decoding
+
+
+Limitations
+-----------
+
+FPGA LTE 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 LTE FEC device, ``CONFIG_RTE_LIBRTE_PMD_FPGA_LTE_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 -vd1172:5052
+
+The physical and virtual functions are compatible with Linux UIO drivers:
+``vfio`` and ``igb_uio``. However, in order to work the FPGA LTE 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 "1172 5052" > /sys/bus/pci/drivers/igb_uio/new_id
+  lspci -vd1172:
+
+
+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 -vd1172:
+
+
+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 LTE 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
+
+
+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 function ``fpga_lte_fec_configure()``, which sets up the
+parameters defined in ``fpga_lte_fec_conf`` structure:
+
+.. code-block:: c
+
+  struct fpga_lte_fec_conf {
+      bool pf_mode_en;
+      uint8_t vf_ul_queues_number[FPGA_LTE_FEC_NUM_VFS];
+      uint8_t vf_dl_queues_number[FPGA_LTE_FEC_NUM_VFS];
+      uint8_t ul_bandwidth;
+      uint8_t dl_bandwidth;
+      uint8_t ul_load_balance;
+      uint8_t dl_load_balance;
+      uint16_t flr_time_out;
+  };
+
+- ``pf_mode_en``: identifies whether only PF is to be used, or the VFs. PF and
+  VFs are mutually exclusive and cannot run simultaneously.
+  Set to 1 for PF mode enabled.
+  If PF mode is enabled all queues available in the device are assigned
+  exclusively to PF and 0 queues given to VFs.
+
+- ``vf_*l_queues_number``: defines the hardware queue mapping for every VF.
+
+- ``*l_bandwidth``: in case of congestion on PCIe interface. The device
+  allocates different bandwidth to UL and DL. The weight is configured by this
+  setting. The unit of weight is 3 code blocks. For example, if the code block
+  cbps (code block per second) ratio between UL and DL is 12:1, then the
+  configuration value should be set to 36:3. The schedule algorithm is based
+  on code block regardless the length of each block.
+
+- ``*l_load_balance``: hardware queues are load-balanced in a round-robin
+  fashion. Queues get filled first-in first-out until they reach a pre-defined
+  watermark level, if exceeded, they won't get assigned new code blocks..
+  This watermark is defined by this setting.
+
+  If all hardware queues exceeds the watermark, no code blocks will be
+  streamed in from UL/DL code block FIFO.
+
+- ``flr_time_out``: specifies how many 16.384us to be FLR time out. The
+  time_out = flr_time_out x 16.384us. For instance, if you want to set 10ms for
+  the FLR time out then set this setting to 0x262=610.
+
+
+An example configuration code calling the function ``fpga_lte_fec_configure()`` is shown
+below:
+
+.. code-block:: c
+
+  struct fpga_lte_fec_conf conf;
+  unsigned int i;
+
+  memset(&conf, 0, sizeof(struct fpga_lte_fec_conf));
+  conf.pf_mode_en = 1;
+
+  for (i = 0; i < FPGA_LTE_FEC_NUM_VFS; ++i) {
+      conf.vf_ul_queues_number[i] = 4;
+      conf.vf_dl_queues_number[i] = 4;
+  }
+  conf.ul_bandwidth = 12;
+  conf.dl_bandwidth = 5;
+  conf.dl_load_balance = 64;
+  conf.ul_load_balance = 64;
+
+  /* setup FPGA PF */
+  ret = fpga_lte_fec_configure(info->dev_name, &conf);
+  TEST_ASSERT_SUCCESS(ret,
+      "Failed to configure 4G FPGA PF for bbdev %s",
+      info->dev_name);
+
+
+Test Application
+----------------
+
+BBDEV provides a test application, ``test-bbdev.py`` and range of test data for testing
+the functionality of FPGA LTE FEC turbo encode and turbo decode, 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 (default=dpdk_path+/app/test-bbdev/test_vectors/bbdev_null.data).
+  "-n", "--num-ops"	: Number of operations to process on device (default=32).
+  "-b", "--burst-size"	: Operations enqueue/dequeue burst size (default=32).
+  "-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 turbo decode or turbo encode data,
+type one of the following:
+
+.. code-block:: console
+
+  ./test-bbdev.py -c validation -n 64 -b 8 -v ./turbo_dec_default.data
+  ./test-bbdev.py -c validation -n 64 -b 8 -v ./turbo_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 as:
+
+- VF_UL_QUEUE_VALUE 4
+- VF_DL_QUEUE_VALUE 4
+- UL_BANDWIDTH 3
+- DL_BANDWIDTH 3
+- UL_LOAD_BALANCE 128
+- DL_LOAD_BALANCE 128
+- FLR_TIMEOUT 610
+
+
+Test Vectors
+~~~~~~~~~~~~
+
+In addition to the simple turbo decoder and turbo 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 FPGA LTE FEC capabilities:
+
+* turbo decoder tests:
+   - ``turbo_dec_c1_k6144_r0_e10376_crc24b_sbd_negllr_high_snr.data``

+   - ``turbo_dec_c2_k3136_r0_e4920_sbd_negllr.data``
+
+
+* turbo encoder tests:

[dpdk-dev] [PATCH v3 0/3] BBDEV turbo_sw PMD compilation fix

[Nicolas Chautru]

Update v3: Cosmetic changes in documentation commit to be more 4G/AVX2 specific. 
Update v2: Splitting into 3 patches as recommended (ignore previous v2 which had a typo)

Based on discussion with maintainer, pushing first a patch to help maintenance of the baseband_turbo_sw which had been lacking.
The documentation is clarified to point to steps on building the SDK libraries which are now publicly available.
(Cosmetic changes to the webpage containing these SDK  will happen in parallel based on feedback from maintainer).
A compile flag is added to be able to build the turbo_sw PMD when the SDK libraries for AVX2 are installed or not. 
In both cases this can be compiled with gcc RTE_TARGET. 
Missing meson build support is also added. 

Note that additional BBDEV changes pushed in previous v1
https://patches.dpdk.org/project/dpdk/list/?series=4657
will be added in a separate v2 patchset which will depend on this very patchset.

[dpdk-dev] [PATCH v4 0/3] BBDEV turbo_sw PMD compilation fix

[Nicolas Chautru]

Update v4: Missed one file for meson build path and minor change to prevent warning 
for some configurations due to unused symbols. 
Update v3: Cosmetic changes in documentation commit to be more 4G/AVX2 specific. 
Update v2: Splitting into 3 patches as recommended (ignore previous v2 which had a typo)

Based on discussion with maintainer, pushing first a patch to help maintenance of the baseband_turbo_sw which had been lacking.
The documentation is clarified to point to steps on building the SDK libraries which are now publicly available.
(Cosmetic changes to the webpage containing these SDK  will happen in parallel based on feedback from maintainer).
A compile flag is added to be able to build the turbo_sw PMD when the SDK libraries for AVX2 are installed or not. 
In both cases this can be compiled with gcc RTE_TARGET. 
Missing meson build support is also added. 

Note that additional BBDEV changes pushed in previous v1
https://patches.dpdk.org/project/dpdk/list/?series=4657
will be added in a separate v2 patchset which will depend on this very patchset.

[dpdk-dev] [PATCH v6 0/3] BBDEV turbo_sw PMD compilation fix

[Nicolas Chautru]

Update v6: Cosmetic change to commit message to include previous Acked-by. 
Update v5: Cosmetic change to remove trailing space and to commit message. Rebased to latest. 
Update v4: Missed one file for meson build path and minor change to prevent warning for some configurations due to unused symbols. 
Update v3: Cosmetic changes in documentation commit to be more 4G/AVX2 specific. 
Update v2: Splitting into 3 patches as recommended (ignore previous v2 which had a typo)

Based on discussion with maintainer, pushing first a patch to help maintenance of the baseband_turbo_sw which had been lacking.
The documentation is clarified to point to steps on building the SDK libraries which are now publicly available.
(Cosmetic changes to the webpage containing these SDK  will happen in parallel based on feedback from maintainer).
A compile flag is added to be able to build the turbo_sw PMD when the SDK libraries for AVX2 are installed or not. 
In both cases this can be compiled with gcc RTE_TARGET. 
Missing meson build support is also added. 

Note that additional BBDEV changes pushed in previous v1
https://patches.dpdk.org/project/dpdk/list/?series=4657
will be added in a separate v2 patchset which will depend on this very patchset.

[dpdk-dev] [PATCH v7 0/3] BBDEV turbo_sw PMD compilation fix

[Nicolas Chautru]

Update v7: Remove architecture specific reference to RTE_CPUFLAG_SSE4_2 reported on travis-ci
Update v6: Cosmetic change to commit message to include previous Acked-by. 
Update v5: Cosmetic change to remove trailing space and to commit message. Rebased to latest. 
Update v4: Missed one file for meson build path and minor change to prevent warning for some configurations due to unused symbols. 
Update v3: Cosmetic changes in documentation commit to be more 4G/AVX2 specific.

Something is wrong with this series:

  https://travis-ci.com/ovsrobot/dpdk/builds/116170401

We cannot enable this on AARCH64 builds - it seems that it wants to take
advantage of facilities that are x86 specific (like SSE 4.2)

Thanks for the feedback. This application can link optionally with AVX/SSE libraries but by default should compile on any platform. This flag can be kept to NULL by default. I will push now as new patchset. 
Thanks

+Intel(R) FPGA LTE FEC Poll Mode Driver
+======================================
+
+The BBDEV FPGA LTE FEC poll mode driver (PMD) supports an FPGA implementation of a VRAN
+Turbo Encode / Decode LTE wireless acceleration function, using Intel's PCI-e and FPGA
+based Vista Creek device.
+
+Features
+--------
+
+FPGA LTE FEC PMD supports the following features:
+
+- Turbo Encode in the DL with total throughput of 4.5 Gbits/s
+- Turbo Decode in the UL with total throughput of 1.5 Gbits/s assuming 8 decoder iterations
+- 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
+
+
+FPGA LTE FEC PMD supports the following BBDEV capabilities:
+
+* For the turbo encode operation:
+   - ``RTE_BBDEV_TURBO_CRC_24B_ATTACH`` :  set to attach CRC24B to CB(s)
+   - ``RTE_BBDEV_TURBO_RATE_MATCH`` :  if set then do not do Rate Match bypass
+   - ``RTE_BBDEV_TURBO_ENC_INTERRUPTS`` :  set for encoder dequeue interrupts
+
+
+* For the turbo decode operation:
+   - ``RTE_BBDEV_TURBO_CRC_TYPE_24B`` :  check CRC24B from CB(s)
+   - ``RTE_BBDEV_TURBO_SUBBLOCK_DEINTERLEAVE`` :  perform subblock de-interleave
+   - ``RTE_BBDEV_TURBO_DEC_INTERRUPTS`` :  set for decoder dequeue interrupts
+   - ``RTE_BBDEV_TURBO_NEG_LLR_1_BIT_IN`` :  set if negative LLR encoder i/p is supported
+   - ``RTE_BBDEV_TURBO_DEC_TB_CRC_24B_KEEP`` :  keep CRC24B bits appended while decoding
+
+
+Limitations
+-----------
+
+FPGA LTE 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 LTE FEC device, ``CONFIG_RTE_LIBRTE_PMD_FPGA_LTE_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 -vd1172:5052
+
+The physical and virtual functions are compatible with Linux UIO drivers:
+``vfio`` and ``igb_uio``. However, in order to work the FPGA LTE 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 "1172 5052" > /sys/bus/pci/drivers/igb_uio/new_id
+  lspci -vd1172:
+
+
+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 -vd1172:
+
+
+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 LTE 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
+
+
+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 function ``fpga_lte_fec_configure()``, which sets up the
+parameters defined in ``fpga_lte_fec_conf`` structure:
+
+.. code-block:: c
+
+  struct fpga_lte_fec_conf {
+      bool pf_mode_en;
+      uint8_t vf_ul_queues_number[FPGA_LTE_FEC_NUM_VFS];
+      uint8_t vf_dl_queues_number[FPGA_LTE_FEC_NUM_VFS];
+      uint8_t ul_bandwidth;
+      uint8_t dl_bandwidth;
+      uint8_t ul_load_balance;
+      uint8_t dl_load_balance;
+      uint16_t flr_time_out;
+  };
+
+- ``pf_mode_en``: identifies whether only PF is to be used, or the VFs. PF and
+  VFs are mutually exclusive and cannot run simultaneously.
+  Set to 1 for PF mode enabled.
+  If PF mode is enabled all queues available in the device are assigned
+  exclusively to PF and 0 queues given to VFs.
+
+- ``vf_*l_queues_number``: defines the hardware queue mapping for every VF.
+
+- ``*l_bandwidth``: in case of congestion on PCIe interface. The device
+  allocates different bandwidth to UL and DL. The weight is configured by this
+  setting. The unit of weight is 3 code blocks. For example, if the code block
+  cbps (code block per second) ratio between UL and DL is 12:1, then the
+  configuration value should be set to 36:3. The schedule algorithm is based
+  on code block regardless the length of each block.
+
+- ``*l_load_balance``: hardware queues are load-balanced in a round-robin
+  fashion. Queues get filled first-in first-out until they reach a pre-defined
+  watermark level, if exceeded, they won't get assigned new code blocks..
+  This watermark is defined by this setting.
+
+  If all hardware queues exceeds the watermark, no code blocks will be
+  streamed in from UL/DL code block FIFO.
+
+- ``flr_time_out``: specifies how many 16.384us to be FLR time out. The
+  time_out = flr_time_out x 16.384us. For instance, if you want to set 10ms for
+  the FLR time out then set this setting to 0x262=610.
+
+
+An example configuration code calling the function ``fpga_lte_fec_configure()`` is shown
+below:
+
+.. code-block:: c
+
+  struct fpga_lte_fec_conf conf;
+  unsigned int i;
+
+  memset(&conf, 0, sizeof(struct fpga_lte_fec_conf));
+  conf.pf_mode_en = 1;
+
+  for (i = 0; i < FPGA_LTE_FEC_NUM_VFS; ++i) {
+      conf.vf_ul_queues_number[i] = 4;
+      conf.vf_dl_queues_number[i] = 4;
+  }
+  conf.ul_bandwidth = 12;
+  conf.dl_bandwidth = 5;
+  conf.dl_load_balance = 64;
+  conf.ul_load_balance = 64;
+
+  /* setup FPGA PF */
+  ret = fpga_lte_fec_configure(info->dev_name, &conf);
+  TEST_ASSERT_SUCCESS(ret,
+      "Failed to configure 4G FPGA PF for bbdev %s",
+      info->dev_name);
+
+
+Test Application
+----------------
+
+BBDEV provides a test application, ``test-bbdev.py`` and range of test data for testing
+the functionality of FPGA LTE FEC turbo encode and turbo decode, 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 (default=dpdk_path+/app/test-bbdev/test_vectors/bbdev_null.data).
+  "-n", "--num-ops"	: Number of operations to process on device (default=32).
+  "-b", "--burst-size"	: Operations enqueue/dequeue burst size (default=32).
+  "-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 turbo decode or turbo encode data,
+type one of the following:
+
+.. code-block:: console
+
+  ./test-bbdev.py -c validation -n 64 -b 8 -v ./turbo_dec_default.data
+  ./test-bbdev.py -c validation -n 64 -b 8 -v ./turbo_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 as:
+
+- VF_UL_QUEUE_VALUE 4
+- VF_DL_QUEUE_VALUE 4
+- UL_BANDWIDTH 3
+- DL_BANDWIDTH 3
+- UL_LOAD_BALANCE 128
+- DL_LOAD_BALANCE 128
+- FLR_TIMEOUT 610
+
+
+Test Vectors
+~~~~~~~~~~~~
+
+In addition to the simple turbo decoder and turbo 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 FPGA LTE FEC capabilities:
+
+* turbo decoder tests:
+   - ``turbo_dec_c1_k6144_r0_e10376_crc24b_sbd_negllr_high_snr.data``
+   - ``turbo_dec_c1_k6144_r0_e10376_crc24b_sbd_negllr_low_snr.data``
+   - ``turbo_dec_c1_k6144_r0_e34560_negllr.data``
+   - ``turbo_dec_c1_k6144_r0_e34560_sbd_negllr.data``
+   - ``turbo_dec_c2_k3136_r0_e4920_sbd_negllr_crc24b.data``
+   - ``turbo_dec_c2_k3136_r0_e4920_sbd_negllr.data``
+
+
+* turbo encoder tests:
+   - ``turbo_enc_c1_k40_r0_e1190_rm.data``
+   - ``turbo_enc_c1_k40_r0_e1194_rm.data``
+   - ``turbo_enc_c1_k40_r0_e1196_rm.data``

The meson changes should go in the same patch as the makefile ones.

+1, also better to have doc in same patch, so all can merged into single patch.

No problem. Pushing in parallel as a new version.
