6. Running the OPAE in a Non-Virtualized Environment
This section shows OPAE examples running directly on the Bare Metal operating
system without a virtual machine or SR-IOV. The host links to the FPGA with a single
PCIe physical function (PF).

Application
6.1. Loading the AFU Image into the FPGA
Use the
fpgaconf
utility to load the AFU image.
sudo fpgaconf <AFU image>
The tool also accepts PCIe Bus:Device:Function (BDF) as an additional optional
arguments if multiple cards are connected to the server. Use the help text (
-h
) for the
OPAE tools to see how additional arguments must be passed. For example:
sudo
fpgaconf -h
.
To identify the BDF run the following command:
lspci | grep 0b2b
Sample output:
37:00.0 Processing accelerators: Intel Corporation Device 0b2b (rev 01)
In the Sample Output, the PCIe Bus is 0x37, the Device is 0x00, and the Function is
0x0.
