With testpmd the interfaces are usable. I have tried using the new RDMA
driver, but run into permission issues there..
vpp# create int rdma host-if enp1s0f1 name rdma-0
create interface rdma: no RDMA devices available, errno = 13. Is the
ib_uverbs module loaded?: Permission denied
ib_uverbs is loaded..
Does the user running VPP have the permissions to read/write
/dev/infiniband/uverbs[0-9]+ files?
Could you share the output of:
~# echo "create int rdma host-if enp1s0f1 name rdma-0" > rdma.vpp
~# sudo timeout 10 strace /usr/bin/vpp "unix { nodaemon exec $PWD/rdma.vpp }
plugins { plugin dpdk_plugin.so { disable } }"
~# sudo dmesg
Thanks.
