9. Sample Test: Native Loopback

This section describes how to run a memory copy test using the Intel provided FPGA factory image and hello_fpga.c host program. The FPGA factory image includes logic to support this test and an internal register with the expected AFU UUID. The hello_fpga.c only works with an FPGA image with this AFU UUID. The acceleration logic (NLB) in the FPGA is programmed to copy CSR_NUM_LINES (cache lines) from source to destination buffer on the host system. For more information refer to the Native Loopback Accelerator Functional Unit (AFU) User Guide for Intel FPGA Programmable Acceleration Card N3000.

Make sure the hugepage is allocated:
  • For CentOS: 
    $ sudo sh -c "echo 20 > /sys/kernel/mm/hugepages/hugepages-2048kB/\
nr_hugepages"
  • For RHEL:
    # echo 20 > /proc/sys/vm/nr_hugepages
Note: Commands must be run as root. 
$	cd /home/<user>/intelrtestack/sw_sample
$	gcc -o hello_fpga -std=gnu99 -rdynamic -ljson-c -luuid -lpthread \
-lopae-c -lm -Wl,-rpath -lopae-c hello_fpga.c
$	sudo ./hello_fpga
