NAME

       mlx5dv_create_mkey - Creates an indirect mkey

       mlx5dv_create_mkey - Destroys an indirect mkey

SYNOPSIS

              #include <infiniband/mlx5dv.h>

              struct mlx5dv_mkey_init_attr {
                  struct ibv_pd   *pd;
                  uint32_t    create_flags;
                  uint16_t    max_entries;
              };

              struct mlx5dv_mkey {
                  uint32_t    lkey;
                  uint32_t    rkey;
              };

              struct mlx5dv_mkey *
              mlx5dv_create_mkey(struct mlx5dv_mkey_init_attr *mkey_init_attr);

              int mlx5dv_destroy_mkey(struct mlx5dv_mkey *mkey);

DESCRIPTION

       Create / destroy an indirect mkey.

       Create an indirect mkey to enable application uses its specific device functionality.

ARGUMENTS

       ##mkey_init_attr##

       pd     ibv protection domain.

       create_flags
              MLX5DV_MKEY_INIT_ATTR_FLAGS_INDIRECT: Indirect mkey is being created.

       max_entries
              Requested  max  number  of  pointed  entries  by this indirect mkey.  The function will update the
              mkey_init_attr->max_entries with the actual mkey value that was created; it will be  greater  than
              or equal to the value requested.

RETURN VALUE

       Upon  success  mlx5dv_create_mkey will return a new struct mlx5dv_mkey on error NULL will be returned and
       errno will be set.

       Upon success destroy 0 is returned or the value of errno on a failure.

Notes

       To let this functionality works a DEVX context should be opened by using mlx5dv_open_device.
