Acked-by: Jijiang Liu <redacted> I think this patch could be merged before Stephen's following patch[1] is merged, then Stephen should rework the patch[1]. Thanks. [1]http://dpdk.org/ml/archives/dev/2015-March/014992.html

So rte_memzone_reserve_bounded() should be used for DMA memory allocation, and rte_mem_phy2mch() should be used for DMA memory address translation to support running fm10k PMD in XEN domain0.
