NAME

       manadv_init_obj - Initialize mana direct verbs object from ibv_xxx structures

SYNOPSIS”

              #include <infiniband/manadv.h>

              int manadv_init_obj(struct manadv_obj *obj, uint64_t obj_type);

DESCRIPTION

       manadv_init_obj()  This function will initialize manadv_xxx structs based on supplied type.  The informa‐
       tion for initialization is taken from ibv_xx structs supplied as part of input.

ARGUMENTS

       obj    The manadv_xxx structs be to returned.

              struct manadv_qp {
                  void        *sq_buf;
                  uint32_t    sq_count;
                  uint32_t    sq_size;
                  uint32_t    sq_id;
                  uint32_t    tx_vp_offset;
                  void        *db_page;
              };

              struct manadv_cq {
                  void        *buf;
                  uint32_t    count;
                  uint32_t    cq_id;
              };

              struct manadv_rwq {
                  void        *buf;
                  uint32_t    count;
                  uint32_t    size;
                  uint32_t    wq_id;
                  void        *db_page;
              };

              struct manadv_obj {
                  struct {
                      struct ibv_qp       *in;
                      struct manadv_qp    *out;
                  } qp;

                  struct {
                      struct ibv_cq       *in;
                      struct manadv_cq    *out;
                  } cq;

                  struct {
                      struct ibv_wq       *in;
                      struct manadv_rwq   *out;
                  } rwq;
              };

       obj_type
              The types of the manadv_xxx structs to be returned.

              enum manadv_obj_type {
                  MANADV_OBJ_QP   = 1 << 0,
                  MANADV_OBJ_CQ   = 1 << 1,
                  MANADV_OBJ_RWQ  = 1 << 2,
              };

RETURN VALUE

       0 on success or the value of errno on failure (which indicates the failure reason).
