Thanks for your reply, Dave.
I would like to use dpdk timer api in vpp, and i don't know whether there is a
substitude.
Here is my code in vpp main func.
rte_timer_subsystem_init();
/* init timer structures */
rte_timer_init(&vpptimer0);
/* load timer0, every second, on master lcore, reloaded automatically */
hz = rte_get_timer_hz();
lcore_id = rte_lcore_id();
rte_timer_reset(&vpptimer0, hz, PERIODICAL, lcore_id, vpp_timer0_cb, NULL);
And i got this Segmentation fault.

Vpp already calls rte_eal_init(...) in .../src/vnet/dpdk/init.c:dpdk_config().
Please don’t call rte_eal_init(..) elsewhere, it simply won’t work.
At a higher level: what are you trying to do? It’s hard to provide meaningful
help with so little information.
Thanks… Dave

Hi, all.
If i would like to use dpdk timer, what extra configuration i need to make?
Since that if i just call func " rte_eal_init(argc, argv)" in vpp, it always
reminds me that there is not enough DPDK mem, why?
Regards,
Ewan.
