NAME¶

manadv_init_obj - Initialize mana direct verbs object from ibv_xxx structures

SYNOPSISӦ

#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 information 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).
