[dpdk-users] ARM server+intel NIC run dpdk met error

[wang.yong19]

Hi,
I tried to run dpdk testpmd on Qualcomm ARM server + intel 82599 NIC + CentOS 7.4. 
However, an error occured with the following output.

[root@localhost app]# ./testpmd -l 4-5 -m 1024 -w 0000:01:00.1 -- -i -a  --forward-mode=io
EAL: Detected 47 lcore(s)

testpmd>
According to the message above, I entered the /sys/bus/pci/devices/0000:01:00.1/ directory and I could not find the resource0/1/2/3 file which will be found at X86 server. Both PF and VF have the same problem. And X710 NIC the same, too.

Does anybody meet this situation before? Can anyone please help me with this problem?

Thanks
Yong
