Subject: [dpdk-stable] [PATCH v14 4/4] examples/ifpga: add example for ifpga APIs
Date: Sun, 21 Feb 2021 22:15:47 -0500
Message-ID: <1613963747-30047-5-git-send-email-wei.huang@intel.com> (raw)
In-Reply-To: <1613963747-30047-1-git-send-email-wei.huang@intel.com>

This example application shows how to use ifpga APIs.
A set of OPAE APIs are implemented based on these ifpga APIs.
You can test each OPAE API by running corresponding command.
A guide is also added to show how to run the example.

+Intel FPGA Sample Application
+=============================
+
+The Intel FPGA sample application is an example of how to use rte_pmd_ifpga API
+to manage Intel FPGA.
+
+Overview
+--------
+
+The Intel FPGA sample application is a simple application that demonstrates
+the use of the APIs provided by ifpga driver in the DPDK.
+A set of OPAE APIs are implemented in this example with 'opae' prefix. These
+APIs use PCI address ('Domain:Bus:Dev.Func') as an unique ID of FPGA,
+application based on OPAE can manage specified FPGA easily with them.
+OPAE (Open Programmable Acceleration Engine) is a software framework for
+managing and accessing programmable accelerators (FPGAs). For more information
+about OPAE, please refer to https://opae.github.io/2.0.0/index.html .
+This application is a readline-like interface that can be used to manage
+Intel FPGA, in a Linux* application environment.
+
+Compiling the Application
+-------------------------
+
+To compile the sample application see :doc:`compiling`
+
+The application is located in the ``ifpga`` sub-directory.
+
+Running the Application
+-----------------------
+
+To run the application in linux environment, issue the following command:
+
+.. code-block:: console
+
+    $ ./<build_dir>/examples/dpdk-ifpga --proc-type=auto
+
+Refer to the *DPDK Getting Started Guide* for general information on running
+applications and the Environment Abstraction Layer (EAL) options.
+
+Commands Description
+--------------------
+
+The following sections provide some explanation of the commands.
+
+help command
+~~~~~~~~~~~~
+
+The application has on-line help for the commands that are available at runtime.
