Intel recommends that you set the clock crossing command depth to 64 entries deep and disable burst support. Intel recommends that you add an Avalon ®-MM Clock Crossing Bridge, available in the IP Catalog, between the CCI-P to Avalon ® MMIO Adapter master port and the DMA Test System Avalon ®-MM slave port. As a result, the CCI-P to Avalon ®-MM Adapter does not support the waitrequest signal. Note: MMIO accesses do not support backpressure. Ī sample application, fpga_dma_test implements the DMA AFU user space driver.

This Quick Start Guide also includes basic information about the Open Programmable Acceleration Engine (OPAE) and configuring an AFU.Īfter 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. 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.

īefore experimenting with the DMA AFU, you must install the Open Programmable Acceleration Engine (OPAE) software package.
The hardware binaries, sources, and the user space driver are available in the following directory: $OPAE_PLATFORM_ROOT/hw/samples/dma_afu. The host application uses this driver such that the DMA moves data between host and FPGA memory. This example provides a user space driver. The Intel ® Acceleration Stack for Intel ® Xeon ® CPU with FPGAs package file ( *.tar.gz), includes the DMA AFU example. The MPF is a Basic Building Block (BBB) that AFUs can use to provide CCI-P traffic shaping operations for transactions with the FIU.
