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 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).
