Good morning, I want to evaluate DPDK on my servers, which are equipped with 4 Mellanox ConnectX-5 Ex 2x100G cards. I have installed MLNX_OFED 5.3-1.0.0 from nvidia, compiled from source with `--upstream-libs --dpdk` flags. I downloaded DPDK 20.11 LTS and compiled following the quick start guide. I have allocated 1024 2MB hugepages for each NUMA node. When I try to run dpdk-helloworld I get:
``` [aperro@ebstortest02 examples]$ sudo ./dpdk-helloworld EAL: Detected 64 lcore(s) EAL: Detected 2 NUMA nodes EAL: Detected static linkage of DPDK EAL: Multi-process socket /var/run/dpdk/rte/mp_socket EAL: Selected IOVA mode 'PA' EAL: No available hugepages reported in hugepages-1048576kB EAL: Probing VFIO support... EAL: VFIO support initialized EAL: DPDK is running on a NUMA system, but is compiled without NUMA support. EAL: This will have adverse consequences for performance and usability. EAL: Please use --legacy-mem option, or recompile with NUMA support.
