Dpdk-regex problem on bluefield

yuchenga · February 7, 2023, 12:23pm

I was trying the dpdk-test-regex and it complains about no devices.
Do I need to manually connect to the Regex engine or something?

Make sure the RegEx engine is active:

systemctl status mlx-regex

If the status is inactive (Active: failed), run:

systemctl start mlx-regex

enable RegEx offloading on the host, run:

host> sudo /etc/init.d/openibd stop host> sudo echo 1024 > /sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages

Then enable host access to the RegEx engine on the DPU:

dpu> echo 1 > /sys/bus/pci/devices/0000:03:00.0/regex/pf/regex_en

Output show app use VFIO driver which nvidia mlx device not build on, likely you not build DPDK correctly with NVIDIA OFED driver,

Follow below build dpdk,

Run app with -a
