Passing " rte_lcore_to_socket_id(rte_get_master_lcore())" as the socket id to rte_memzone_reserve resolves these issues as the master lcore doesn't change. -----Original Message----- From: Ferriter, Cian Sent: Tuesday, January 13, 2015 9:22 AM To: dev@dpdk.org Cc: Ferriter, Cian Subject: [PATCH] lib/librte_ether: change socket_id passed to rte_memzone_reserve Change the socket id that is passed to rte_memzone_reserve from the socket id of current logical core to the socket id of the master_lcore. --- lib/librte_ether/rte_ethdev.c | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) mode change 100644 => 100755 lib/librte_ether/rte_ethdev.c -- 1.7.4.1 diff --git a/lib/librte_ether/rte_ethdev.c b/lib/librte_ether/rte_ethdev.c old mode 100644 new mode 100755 index 95f2ceb..835540d --- a/lib/librte_ether/rte_ethdev.c +++ b/lib/librte_ether/rte_ethdev.c @@ -184,7 +184,7 @@ rte_eth_dev_data_alloc(void) if (rte_eal_process_type() == RTE_PROC_PRIMARY){ mz = rte_memzone_reserve(MZ_RTE_ETH_DEV_DATA, RTE_MAX_ETHPORTS * sizeof(*rte_eth_dev_data), - rte_socket_id(), flags); + rte_lcore_to_socket_id(rte_get_master_lcore()), flags); } else mz = rte_memzone_lookup(MZ_RTE_ETH_DEV_DATA); if (mz == NULL)
