Hi Pim, Looking at https://doc.dpdk.org/guides/nics/dpaa2.html, it looks like it does not use the PCIe bus but something specific called the "FSL MC bus". Normally, VPP DPDK plugin should build a list of eligible devices at startup, by scanning PCIe or VMBus (HyperV virtualized bus) but it does not know anything about FSL MC. To support that, one probably need to implement something like what was done for VMBus: https://gerrit.fd.io/r/c/vpp/+/15311
