Hi, Morten Thank you for pointing out this opportunity - to enable IOVA VA mode support in mlx5 drivers. Now we propose this patch: http://patches.dpdk.org/project/dpdk/patch/20230412125320.8585-1-viachesl...@nvidia.com/
The mlx5 hardware has its own MMU facility, no extra efforts are needed to support VA from PMD side.
