Hi Team, We are facing an issue with running DPDK on NIC XL710/X710 with SRIOV based configuration. while configuring 4 cores in system we get an issue that DPDK get stuck while polling the packets from rings.
here is the stack below #0 0x00007f614242acae in common_ring_mc_dequeue (mp=0x7f565d6c3d80, obj_table=0x7f565d6c9ed0, n=544) at /mnt/utkarsh/git_repos/190619_clone/mn-vpp/fastpath/build-vpp-mav/vpp/build-root/build-vpp-native/dpdk/dpdk-18.05/drivers/mempool/ring/rte_mempool_ring.c:30 #1 0x00007f61425a06d1 in rte_mempool_ops_dequeue_bulk (n=544, obj_table=<optimized out>, mp=0x7f565d6c3d80) at /mnt/utkarsh/git_repos/190619_clone/mn-vpp/fastpath/build-vpp-mav/vpp/build-root/build-vpp-native/dpdk/dpdk-18.05/x86_64-native-linuxapp-gcc/include/rte_mempool.h:679 #2 __mempool_generic_get (cache=0x7f565d6c9ec0, n=32, obj_table=0x7f565d61b4c0, mp=0x7f565d6c3d80) at /mnt/utkarsh/git_repos/190619_clone/mn-vpp/fastpath/build-vpp-mav/vpp/build-root/build-vpp-native/dpdk/dpdk-18.05/x86_64-native-linuxapp-gcc/include/rte_mempool.h:1495 #3 rte_mempool_generic_get (cache=0x7f565d6c9ec0, n=32, obj_table=0x7f565d61b4c0, mp=0x7f565d6c3d80) at /mnt/utkarsh/git_repos/190619_clone/mn-vpp/fastpath/build-vpp-mav/vpp/build-root/build-vpp-native/dpdk/dpdk-18.05/x86_64-native-linuxapp-gcc/include/rte_mempool.h:1558 #4 rte_mempool_get_bulk (n=32, obj_table=0x7f565d61b4c0, mp=0x7f565d6c3d80) at /mnt/utkarsh/git_repos/190619_clone/mn-vpp/fastpath/build-vpp-mav/vpp/build-root/build-vpp-native/dpdk/dpdk-18.05/x86_64-native-linuxapp-gcc/include/rte_mempool.h:1591 #5 i40e_rxq_rearm (rxq=0x7f565db36900) at /mnt/utkarsh/git_repos/190619_clone/mn-vpp/fastpath/build-vpp-mav/vpp/build-root/build-vpp-native/dpdk/dpdk-18.05/drivers/net/i40e/i40e_rxtx_vec_avx2.c:61 #6 _recv_raw_pkts_vec_avx2 (split_packet=0x7f62d8130c80 "", nb_pkts=32, rx_pkts=0x7f62d7ac6940, rxq=0x7f565db36900) at /mnt/utkarsh/git_repos/190619_clone/mn-vpp/fastpath/build-vpp-mav/vpp/build-root/build-vpp-native/dpdk/dpdk-18.05/drivers/net/i40e/i40e_rxtx_vec_avx2.c:192 #7 i40e_recv_scattered_burst_vec_avx2 (rx_queue=rx_queue@entry=0x7f565db36900, rx_pkts=rx_pkts@entry=0x7f62d7ac6940, nb_pkts=nb_pkts@entry=32) at /mnt/utkarsh/git_repos/190619_clone/mn-vpp/fastpath/build-vpp-mav/vpp/build-root/build-vpp-native/dpdk/dpdk-18.05/drivers/net/i40e/i40e_rxtx_vec_avx2.c:600 #8 0x00007f61425a256b in i40e_recv_scattered_pkts_vec_avx2 (rx_queue=0x7f565db36900, rx_pkts=0x7f62d7ac6940, nb_pkts=256) at /mnt/utkarsh/git_repos/190619_clone/mn-vpp/fastpath/build-vpp-mav/vpp/build-root/build-vpp-native/dpdk/dpdk-18.05/drivers/net/i40e/i40e_rxtx_vec_avx2.c:639 #9 0x00007f6142376ea4 in rte_eth_rx_burst (nb_pkts=256, rx_pkts=0x7f62d7ac6940, queue_id=1, port_id=0) at /home/utkarsh/git_repos/190619_clone/mn-vpp/fastpath/build-vpp-mav/vpp/build-root/install-vpp-native/dpdk/include/dpdk/rte_ethdev.h:3844 #10 dpdk_device_input (queue_id=1, thread_index=<optimized out>, node=0x7f62d867f480, xd=0x7f62d7b11580, dm=<optimized out>, vm=0x7f62d7a1ed40) at /mnt/utkarsh/git_repos/190619_clone/mn-vpp/fastpath/build-vpp-mav/vpp/build-data/../src/plugins/dpdk/device/node.c:459 #11 dpdk_input_node_fn (vm=<optimized out>, node=<optimized out>, f=<optimized out>) at /mnt/utkarsh/git_repos/190619_clone/mn-vpp/fastpath/build-vpp-mav/vpp/build-data/../src/plugins/dpdk/device/node.c:640 #12 0x00007f6945d3a61b in dispatch_node (last_time_stamp=345121778085630, frame=0x0, dispatch_state=VLIB_NODE_STATE_POLLING, type=VLIB_NODE_TYPE_INPUT, node=0x7f62d867f480, vm=0x7f62d7a1ed40) at /mnt/utkarsh/git_repos/190619_clone/mn-vpp/fastpath/build-vpp-mav/vpp/build-data/../src/vlib/main.c:988 #13 vlib_main_or_worker_loop (is_main=0, vm=0x7f62d7a1ed40) at /mnt/utkarsh/git_repos/190619_clone/mn-vpp/fastpath/build-vpp-mav/vpp/build-data/../src/vlib/main.c:1507 #14 vlib_worker_loop (vm=0x7f62d7a1ed40) at /mnt/utkarsh/git_repos/190619_clone/mn-vpp/fastpath/build-vpp-mav/vpp/build-data/../src/vlib/main.c:1641 #15 0x00007f694485b418 in clib_calljmp () at /mnt/utkarsh/git_repos/190619_clone/mn-vpp/fastpath/build-vpp-mav/vpp/build-data/../src/vppinfra/longjmp.S:110 #16 0x00007f49dc7fcdc0 in ??
