The infiniband specification describes register physical memory region. consumer can request an iova to be returned which can be same or different from the one requested.
we provide a physical buffer list (which is list of start physical address of pages) as input to the call that registers physical memory. while allocating any memory the physical address is already associated with a virtual address. still we can request a new virtual address to be returned for region. what is significance of iova, since one virtual address is already associated with physical address that we provide. -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
