2.2. The DMA AFU Software Package

The Intel® Acceleration Stack for Intel® Xeon® CPU with FPGAs package file (*.tar.gz), includes the DMA AFU example. This example provides a user space driver. The host application uses this driver such that the DMA moves data between host and FPGA memory. The hardware binaries, sources, and the user space driver are available in the following directory: $OPAE_PLATFORM_ROOT/hw/samples/dma_afu .

Before experimenting with the DMA AFU, you must install the Open Programmable Acceleration Engine (OPAE) software package. Refer to Installing the OPAE Software Package in the Intel® Acceleration Stack Quick Start Guide for Intel® Programmable Acceleration Card with Intel® Arria® 10 GX FPGA for installation instructions. This Quick Start Guide also includes basic information about the Open Programmable Acceleration Engine (OPAE) and configuring an AFU.

After installing the Open Programmable Acceleration Engine (OPAE) software package, a sample host application and the DMA AFU user space driver are available in the following directory: $OPAE_PLATFORM_ROOT/hw/samples/dma_afu/sw .

A sample application, fpga_dma_test implements the DMA AFU user space driver.
