CREATE_RWQ_IND_TBL(3) Libibverbs Programmer's Manual CREATE_RWQ_IND_TBL(3)
ibv_create_rwq_ind_table, ibv_destroy_rwq_ind_table - create or
destroy a Receive Work Queue Indirection Table (RWQ IND TBL).
#include <infiniband/verbs.h>
struct ibv_rwq_ind_table *ibv_create_rwq_ind_table(struct ibv_context *context,
struct ibv_rwq_ind_table_init_attr *init_attr);
int ibv_destroy_rwq_ind_table(struct ibv_rwq_ind_table *rwq_ind_table);
ibv_create_rwq_ind_table() creates a RWQ IND TBL associated with the
ibv_context context. The argument init_attr is an
ibv_rwq_ind_table_init_attr struct, as defined in
<infiniband/verbs.h>.
struct ibv_rwq_ind_table_init_attr {
uint32_t log_ind_tbl_size; /* Log, base 2, of Indirection table size */
struct ibv_wq **ind_tbl; /* Each entry is a pointer to Receive Work Queue */
uint32_t comp_mask; /* Identifies valid fields. Use ibv_ind_table_init_attr_mask */
};
The function ibv_create_rwq_ind_table() will create a RWQ IND TBL
that holds a table of Receive Work Queue. For further usage of the
created object see below NOTES.
ibv_destroy_rwq_ind_table() destroys the RWQ IND TBL rwq_ind_table.
ibv_create_rwq_ind_table() returns a pointer to the created RWQ IND
TBL, or NULL if the request fails.
ibv_destroy_rwq_ind_table() returns 0 on success, or the value of
errno on failure (which indicates the failure reason).
The created object should be used as part of ibv_create_qp_ex() to
enable dispatching of incoming packets based on some RX hash
configuration.
