Just to make sure the correct one is reviewed. 1) v7 had similar issue mentioned http://patches.dpdk.org/patch/56585/ 2) v11 addressed the review comments and you have given the Acked-by for mempool change http://patches.dpdk.org/patch/61559/ My thought process in the TB meeting was, since rte_mempool_populate_from_pg_sz_chunks() reviwed replace rte_pktmbuf_pool_create's rte_mempool_populate_default() with rte_mempool_populate_from_pg_sz_chunks() in IOVA == VA case to avoid a new KNI mempool_create API. > > Currently, in rte_mempool_populate_default(), when the mempool is > populated, we first try to allocate one iova-contiguous block of (n * > elt_size).
