Can you please show me in the current code where it is being exported? I
have only moved definitions to _common_ files, not sure why it should be
exported now. I searched in the current code for RTE_DEFINE_PER_LCORE
#home/rkerur/dpdk-tmp/dpdk# grep -ir RTE_DEFINE_PER_LCORE *
app/test/test_per_lcore.c:static RTE_DEFINE_PER_LCORE(unsigned, test) =
0x12345678;
lib/librte_eal/linuxapp/eal/eal_thread.c:RTE_DEFINE_PER_LCORE(unsigned,
_lcore_id) = LCORE_ID_ANY;
lib/librte_eal/linuxapp/eal/eal_thread.c:RTE_DEFINE_PER_LCORE(unsigned,
_socket_id) = (unsigned)SOCKET_ID_ANY;
lib/librte_eal/linuxapp/eal/eal_thread.c:RTE_DEFINE_PER_LCORE(rte_cpuset_t,
_cpuset);
lib/librte_eal/bsdapp/eal/eal_thread.c:RTE_DEFINE_PER_LCORE(unsigned,
_lcore_id) = LCORE_ID_ANY;
lib/librte_eal/bsdapp/eal/eal_thread.c:RTE_DEFINE_PER_LCORE(unsigned,
_socket_id) = (unsigned)SOCKET_ID_ANY;
lib/librte_eal/bsdapp/eal/eal_thread.c:RTE_DEFINE_PER_LCORE(rte_cpuset_t,
_cpuset);
lib/librte_eal/common/include/rte_per_lcore.h:#define
RTE_DEFINE_PER_LCORE(type, name) \

RTE_DEFINE_PER_LCORE(int, _thread_id) = -1;
