SZEDATA2 poll mode driver library
|
||||
=================================
|
||||
|
||||
The SZEDATA2 poll mode driver library implements support for the Netcope
|
||||
FPGA Boards (**NFB-40G2, NFB-100G2, NFB-200G2QL**) and Silicom **FB2CGG3** card,
|
||||
FPGA-based programmable NICs. The SZEDATA2 PMD uses interface provided by the libsze2
|
||||
library to communicate with the NFB cards over the sze2 layer.
|
||||
|
||||
More information about the
|
||||
`NFB cards <http://www.netcope.com/en/products/fpga-boards>`_
|
||||
and used technology
|
||||
(`Netcope Development Kit <http://www.netcope.com/en/products/fpga-development-kit>`_)
|
||||
can be found on the `Netcope Technologies website <http://www.netcope.com/>`_.
|
||||
|
||||
.. note::
|
||||
|
||||
Currently the driver is supported only on x86_64 architectures.
|
||||
Only x86_64 versions of the external libraries are provided.
|
||||
|
||||
Prerequisites
|
||||
-------------
|
||||
|
||||
This PMD requires kernel modules which are responsible for initialization and
|
||||
allocation of resources needed for sze2 layer function.
|
||||
Communication between PMD and kernel modules is mediated by libsze2 library.
|
||||
These kernel modules and library are not part of DPDK and must be installed
|
||||
separately:
|
||||
|
||||
* **libsze2 library**
|
||||
|
||||
The library provides API for initialization of sze2 transfers, receiving and
|
||||
transmitting data segments.
|
||||
|
||||
* **Kernel modules**
|
||||
|
||||
* combo6core
|
||||
* combov3
|
||||
* szedata2
|
||||
* szedata2_cv3 or szedata2_cv3_fdt
|
||||
|
||||
Kernel modules manage initialization of hardware, allocation and
|
||||
sharing of resources for user space applications.
|
||||

||||

Versions of the packages
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
The minimum version of the provided packages:
|
||||
|
||||
* for DPDK from 18.05: **4.4.1**
|
||||
|
||||
* for DPDK up to 18.02 (including): **3.0.5**
|
||||
|
||||
|
||||
Using the SZEDATA2 PMD
|
||||
----------------------
|
||||
|
||||
From DPDK version 16.04 the type of SZEDATA2 PMD is changed to PMD_PDEV.
|
||||
SZEDATA2 device is automatically recognized during EAL initialization.
|
||||
No special command line options are needed.
|
||||
|
||||
Kernel modules have to be loaded before running the DPDK application.
|
||||
|
||||
NFB card architecture
|
||||
---------------------
|
||||
|
||||
The NFB cards are multi-port multi-queue cards, where (generally) data from any
|
||||
Ethernet port may be sent to any queue.
|
||||
They were historically represented in DPDK as a single port.
|
||||
|
||||
However, the new NFB-200G2QL card employs an add-on cable which allows to connect
|
||||
it to two physical PCI-E slots at the same time (see the diagram below).
|
||||
This is done to allow 200 Gbps of traffic to be transferred through the PCI-E
|
||||
bus (note that a single PCI-E 3.0 x16 slot provides only 125 Gbps theoretical
|
||||
throughput).
|
||||
|
||||
Since each slot may be connected to a different CPU and therefore to a different
|
||||
NUMA node, the card is represented as two ports in DPDK (each with half of the
|
||||
queues), which allows DPDK to work with data from the individual queues on the
|
||||
right NUMA node.
|
||||
|
||||

||||
|
||||
NFB-200G2QL high-level diagram
|
||||
|
||||
Limitations
|
||||
-----------
|
||||
|
||||
The SZEDATA2 PMD does not support operations related to Ethernet ports
|
||||
(link_up, link_down, set_mac_address, etc.).
|
||||
|
||||
NFB cards employ multiple Ethernet ports.
|
||||
Until now, Ethernet port-related operations were performed on all of them
|
||||
(since the whole card was represented as a single port).
|
||||
With NFB-200G2QL card, this is no longer viable (see above).
|
||||
|
||||
Since there is no fixed mapping between the queues and Ethernet ports, and since
|
||||
a single card can be represented as two ports in DPDK, there is no way of
|
||||
telling which (if any) physical ports should be associated with individual
|
||||
ports in DPDK.
|
||||
|
||||
Example of usage
|
||||
----------------
|
||||
|
||||
Read packets from 0. and 1. receive channel and write them to 0. and 1.
|
||||
transmit channel:
|
||||
|
||||
.. code-block:: console
|
||||
|
||||
./<build_dir>/app/dpdk-testpmd -l 0-3 -n 2 \
|
||||
-- --port-topology=chained --rxq=2 --txq=2 --nb-cores=2 -i -a
|
||||
|
||||
Example output:
|
||||
|
||||
.. code-block:: console
