Ok. I tried this on a HUAWEI Kunpeng 920 running 4.18.0-348.2.1.el8_5.aarch64.
I can load the bnxt_en kernel driver and the DPDK PMD without issues.
And I did load vfio with enable_unsafe_noiommu_mode=1 .
While we are pursuing this further internally,
I have added Honnappa to see if he can provide any insight.
