This document describes the DOCA FlexIO Build tool.
The DOCA FlexIO driver exposes the API for managing and running code over the data path accelerator. The DPA is an embedded user-programmable processor in the NVIDIA® BlueField®-3 DPU.
Writing the FlexIO application requires compiling both host and device stubs into single binary file.
The FlexIO Build tool is a wrapper for the DPACC compiler to compile device code.
Refer to NVIDIA DOCA DPA Subsystem Programming Guide for more information.
Refer to NVIDIA DOCA DPACC Compiler User Guide for more information.
build_flexio_device.sh <app-name> <source-file> <build-dir>
Please refer to section Tool Flags for more information.
build_flexio_device.sh l2_reflector_device /opt/mellanox/doca/applications/l2_reflector/device/l2_reflector_device.c /tmp/dpacc-output/
This command builds and compiles the
l2_reflector_device.a static library which is then placed under
Application name. This flag is important as it determines how the
DPACC defines the following:
This is used from the host application.
|<source-file>||DPA device source code. This code is cross-compiled and bundled in the output library.|
|<build-dir>||Directory where the library will be placed.|
