Can not run test-regex on host

[waterzhu]

I wanna run

/home/notroot/regex# /opt/mellanox/dpdk/bin/dpdk-test-regex -c 1 -a 01:00.0,class=regex --file-prefix=rxpbench -- --rules ./rof/helloworld.rof2.binary --data helloworld.txt --nb_job 1

on host to test the RXP, but it failed and the log shows below.

EAL: Detected 8 lcore(s)

My env is

• BlueField-2
• HostOs: 5.4.0-107-generic 20.04.4 LTS (Focal Fossa)
• BF Os: Linux BF2-Nvidia 5.4.0-1023-bluefield
• DOCA: 1.2.1

But when I run the same test-regex on BF, it works:

root@BF2-Nvidia:/home/ubuntu/regex# /opt/mellanox/dpdk/bin/dpdk-test-regex -c 1 -a 03:00.0,class=regex --file-prefix=rxpbench -- --rules ./rof/helloworld.rof2.binary --data helloworld.txt --nb_job 1

I wanna know why I cannot run the test on the host?

Hi Waterzhu,

It would be great if you could confirm if you have referred to the following link —> RXPBench :: NVIDIA DOCA SDK Documentation

In addition, the output displays the following message:

mlx5_regex: Not enough capabilities to support RegEx, maybe old FW/OFED version?
mlx5_common: Failed to load driver regex_mlx5
EAL: Requested device 0000:01:00.0 cannot be used

Please confirm if the OFED and firmware on the host are latest. This can be checked as follows:

a. #ofed_info -s
b. #ibv_devinfo |grep fw

Also, to confirm you are using the correct device, please run the below command on the host:
#mst status -v

Thanks,
Namrata.
