Hi, I observe an issue with IOVA address returned by api rte_memzone_reserve_aligned (flags= RTE_MEMZONE_IOVA_CONTIG) used for queue memory allocation. With high level debugging, I notice that IOVA address returned in mz->iova is not mapped by VFIO_IOMMU_MAP_DMA so in turn SMMU exception is seen.
*Details for the setup* Platform: Armv8 (Broadcom Stingray) DPDK release: DPDK 20.08 <http://fast.dpdk.org/rel/dpdk-20.08.tar.xz> PMD patch: https://patches.dpdk.org/project/dpdk/list/?series=&submitter=1907&state=&q=&archive=&delegate= dpdk-test is launched using below command *dpdk-test --vdev <cryptopmd_name> -w 0000:00:00.0 --iova-mode pa * The test suite is launched over dpdk-test application command prompt using command ‘cryptodev_<cryptopmd_name>_autotest’ The issue is seen when several iterations of above test_suite is executed which in turn do multiple calls to rte_memzone_reserve_aligned, rte_mempool_create and rte_memzone_free, rte_mempool_free. Function *vfio_type1_dma_mem_map* with map/unmap event is executed several times during test_suite run. Any inputs would be helpful. Thanks, Vikas
