Hi,
I have allocated hugepages. I still get the same error.
I changed the code to the following but I still get the same error:
------------- Code ---------------
struct rte_mempool *mempool = NULL;
#define NB_MBUF 8192
#define PATH_MAX 4096
int
main(int argc, char **argv)
{
struct rte_mbuf *mbuf = NULL;
char buf[PATH_MAX];
struct rte_mempool *mp;
int socket;
socket = SOCKET_ID_ANY;
mp = rte_pktmbuf_pool_create(buf, NB_MBUF, 32, 0,
RTE_MBUF_DEFAULT_BUF_SIZE, socket);
}
regards,
Katie

Make sure you have allocated hugepages before running the application

Hi,
You are using Socket 0, and might be there is no memory in this socket or no
memory left in this socket 0. Try with SOCKET_ID_ANY.

Subject: [dpdk-users] Help with mbuf and mempool
Hello,
I am trying to allocate an mbuf to use for IP fragmentation. When instantiating
a mempool using rte_pktmbuf_pool_create() function, I keep getting the
following error message.
Error Message:
* MEMPOOL: Cannot allocate tailq entry!
Will you please let me know what I am missing?
Regards,
Katie
