Hi:
We are using our own Makefile in building dpdk program. Recently we are working
on upgrading from DPDK 1.3 to DPDK 1.7. I found the rte_ixgbe_pmd_init has been
replaced by PMD_REGISTER_DRIVER. So I delete rte_ixgbe_pmd_init calls. But
after that, our dpdk program could not correctly find the NIC anymore. After
digging into it a little more, I found the code dose not correctly register the
driver type we are using, which is ixgbe.
To isolate the problem, I hacked a smal example l3fwd, and only have the main.c
file like this for my testing purpose.
#include <rte_config.h>
#include <rte_eal.h>
#include "main.h"
int
MAIN(int argc, char **argv)
{
/* init EAL */
int ret = rte_eal_init(argc, argv);
printf("ret %d\n", ret);
return 0;
}
I found if I use the Makefile provided in the example, the program will find
the ixgbe NIC. But if I just use these 2 commands to compile and link it. It
will not find the ixgbe NIC.
gcc -I../../x86_64-native-linuxapp-gcc/include
-L../../x86_64-native-linuxapp-gcc/lib -lrte_eal -c main.c
gcc -o l3fwd main.o -L../../x86_64-native-linuxapp-gcc/lib -lrte_eal
-lrte_distributor -lrte_pipeline -lrte_port -lrte_timer -lrte_hash -lrte_acl
-lm -lrt -lrte_mbuf -lethdev -lrte_malloc -lrte_mempool -lrte_ring -lc -lm
-lrte_cmdline -lrte_cfgfile -lrte_pmd_bond -lrte_pmd_ixgbe -lrte_pmd_e1000
-lrte_pmd_ring -lpthread -ldl -lrt
Can someone share some light on what is magic of the dpdk Makefile to correctly
register the NIC type?
Thank you so much.
