Hello,
I need clarification while creating direct/indirect buffers for mbuf. I couldn't find exact documentation, and I just looked over the fragmentation test case and saw that two pools were created. One is a
direct pool, and the other is an indirect pool. Here are the methods to create pools:
direct_pool = rte_pktmbuf_pool_create("FRAG_D_MBUF_POOL",
NUM_MBUFS, BURST, 0,
RTE_MBUF_DEFAULT_BUF_SIZE,
SOCKET_ID_ANY);
indirect_pool = rte_pktmbuf_pool_create("FRAG_I_MBUF_POOL",
NUM_MBUFS, BURST, 0,
0, SOCKET_ID_ANY)
I couldn't see the exact difference. Just the "data_room_size" parameter is different. If this parameter is 0, then is the pool indirect?
Thanks all
