Hi Thomas, I tried installing things from scratch two days ago and have gotten things working! I think part of the problem was figuring out the correct hugepage allocation for my system. If I recall correctly, I tried setting up my system with default page size 1G but perhaps didn't have enough pages allocated at the time. Currently have the following which gives me the output you've shown previously. root@yeti-04:~/dpdk-21.11# usertools/dpdk-hugepages.py -s Node Pages Size Total 0 16 1Gb 16Gb 1 16 1Gb 16Gb root@yeti-04:~/dpdk-21.11# echo show port summary all | build/app/dpdk-testpmd --in-memory -- -i EAL: Detected CPU lcores: 80 EAL: Detected NUMA nodes: 2 EAL: Detected static linkage of DPDK EAL: Selected IOVA mode 'PA' EAL: No free 2048 kB hugepages reported on node 0 EAL: No free 2048 kB hugepages reported on node 1 EAL: No available 2048 kB hugepages reported EAL: VFIO support initialized EAL: Probe PCI driver: mlx5_pci (15b3:1017) device: 0000:af:00.0 (socket 1) TELEMETRY: No legacy callbacks, legacy socket not created Interactive-mode selected testpmd: create a new mbuf pool : n=779456, size=2176, socket=0 testpmd: preferred mempool ops selected: ring_mp_mc testpmd: create a new mbuf pool : n=779456, size=2176, socket=1 testpmd: preferred mempool ops selected: ring_mp_mc Warning! port-topology=paired and odd forward ports number, the last port will pair with itself.
