Memory allocation is tricky in DPDK, but are you talking about rte_malloc or
rte_mempool allocagtion. Each h has a different way to get memory. Look at the
rte_memzone code it does the lowest level allocation of memory and use huge
pages. Also look at the email list for patches submitted by Anatoly Burakov he
just re-wrote the memory system and has some good explanations in the patches
an in the docs for DPDK.
