3.1. Setup Prerequisites

To install the Intel® PAC and OPAE SDK on a supported platform, follow the Intel Acceleration Stack Quick Start Guide for Intel Programmable Acceleration Card with Intel Arria 10 GX FPGA. If you only want to evaluate network port operation using the pre-compiled AFs from the OPAE SDK installation, you do not need the Intel® Quartus® Prime Pro Edition software.

The OPAE_PLATFORM_ROOT environment variable points to the location where you installed the OPAE SDK, which is delivered as part of the Acceleration Stack for Intel® PAC with Intel® Arria® 10 GX FPGA.

In a multi-card system, use the following command to find the device sysfs entry associated with the desired PCIe device:
$ ls -lrt /sys/class/fpga/intel-fpga-dev.*/
Sample output:
/sys/class/fpga/intel-fpga-dev.1/:

drwxr-xr-x.  4 root root    0 Apr  7 23:27 intel-fpga-port.0

This shows that the dev1 PCIe B:D.F is af:00.0 and dev0 PCIe B:D.F is 86:00.0.
