Yes, it's probably the same issue.
I saw the same error using vfio-pci with iommu enabled on a C3000 board a
couple of months ago. Setting iova-mode to pa in the arguments to
rte_eal_init() made it work. One of my colleagues submitted a patch which
will allow this to be set in startup.conf like so:
dpdk {
iova-mode pa
}
The patch was submitted after 20.01 was released. So it won't help you if
you have to run 19.08. You could build from the current master branch, try
using igb_uio (which should result in the iova mode being set to pa) or
wait for the next release.
