Hello All,
We are using DDPDK 19.11 and when we call *rte_pktmbuf_pool_create() *API
allocate memory,
we could see the EINVAL ( EINVAL - cache size provided is too large, or
priv_size is not aligned ) return from that above API.
We are seeing the issue only when we pass the Priv_size value of 64 bytes
which is aligned to RTE_MBUF_PRIV_ALIGN(8 bytes).
Here is our snippet of our code base:
#define MBUF_CACHE_SIZE *512 *
#define MBUF_PRIV_SIZE *64*
#define FRAME_LEN *9216*
#define NO_OF_MBUF
*52736 *
/*define in rte_config.h */
#define RTE_PKTMBUF_HEADROOM 128
pool = rte_pktmbuf_pool_create(name, num_mbufs,
MBUF_CACHE_SIZE, MBUF_PRIV_SIZE,
frame_len + RTE_PKTMBUF_HEADROOM,
rte_socket_id());
The above check was failed with EINVAL
Could you please suggest if there is any known issue or limitation w.r.t
19.11
Thanks,
Kamaraj
