Hi Junzhi,
Can you please change log_num_mgm_entry_size=-1
Can you please run testpmd and specify only pf 04:00.0
Thanks,
Olga

Subject: [dpdk-users] Cannot run DPDK applications using Mellanox NIC
Hi everyone,
I am sorry that I did not give many examples and details last time.
The Mellanox NIC is
Device #1:
----------
Device Type: ConnectX3Pro
Part Number: MCX313A-BCC_Ax
Description: ConnectX-3 Pro EN network interface card; 40GigE; single-port QSFP; PCIe3.0 x8 8GT/s; RoHS R6
PSID: MT_1060111023
PCI Device Name: /dev/mst/mt4103_pci_cr0
Port1 MAC: ec0d9a07dc90
Port2 MAC: ec0d9a07dc91
Versions: Current Available
FW 2.42.5000 N/A
PXE 3.4.0752 N/A
The Mellanox OFED version is 4.4. I set 12 VFs on the host, and I can look at them like this:
$ lspci | grep Mellanox
04:00.0 Ethernet controller: Mellanox Technologies MT27520 Family [ConnectX-3 Pro]

In file /etc/modprobe.d/mlx4_core.conf:
options mlx4_core log_num_mgm_entry_size=-7 num_vfs=12 port_type_array=2 probe_vf=12
My DPDK version is 18.08, and in file /config/common_base, I set:
CONFIG_RTE_LIBRTE_MLX4_PMD=y
After doing modprobe -a ib_uverbs mlx4_en mlx4_core mlx4_ib
I run several DPDK applications, and I got the same error message as follows.
Thank you!

I have installed the Mellanox OFED (version 4.4, only the newest version is compatible to Ubuntu 18.04) and configure it by instructions in DPDK doc page (https://emea01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fdoc.dpdk.org%2Fguides%2Fnics%2Fmlx4.html&data=02%7C01%7Colgas%40mellanox.com%7Cda3acc6743514ffaf81f08d640196525%7Ca652971c7d2e4d9ba6a4d149256f461b%7C0%7C0%7C636766875152604596&sdata=HgF%2FynJD%2B5U2ZegDVUc%2BmqCv5Py5Ak7xdIk2Nhyemg4%3D&reserved=0 <https://emea01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fdoc.dpdk.org%2Fguides%2Fnics%2Fmlx4.html&data=02%7C01%7Colgas%40mellanox.com%7Cda3acc6743514ffaf81f08d640196525%7Ca652971c7d2e4d9ba6a4d149256f461b%7C0%7C0%7C636766875152604596&sdata=HgF%2FynJD%2B5U2ZegDVUc%2BmqCv5Py5Ak7xdIk2Nhyemg4%3D&reserved=0>). The DPDK version is 18.08. I do not bind the Mellanox NIC to DPDK driver because the driver mlx4_core should be used for Mellanox NICs. Currently I am using 2MB hugepages (number: 1024).
