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