Hi,



How do I ask SPDK/DPDK to restrict the iova and phys_addr allocation to
first 128 GB of its address space ?



In short I want to restrict



Function: vfio_type1_dma_map

dma_map.vaddr = ms[i].addr_64;

dma_map.iova = ms[i].phys_addr;



iova address which gets programmed in iommu restricted to first 128 GB of
space ?



I am using ARM64 port, but it should not have anything to do with
architecture anyway.



Regards,

Oza.
