mlx5dv_get_export_sizes(3)

NAME
mlx5dv_get_export_sizes - Query export buffer sizes for mlx5 objects

SYNOPSIS

        #include <infiniband/mlx5dv.h>
        struct mlx5dv_export_sizes {
            uint32_t var_attrs_size;
            uint32_t devx_umem_attrs_size;
            uint32_t devx_obj_attrs_size;
        };
        void mlx5dv_get_export_sizes(struct mlx5dv_export_sizes *sizes);

DESCRIPTION
mlx5dv_get_export_sizes() returns the buffer sizes required by the export/import APIs for each supported object type. The caller should use these sizes to allocate data buffers before calling the corresponding export/import functions.

The returned sizes reflect the library’s internal data layout and may change between library versions.

ARGUMENTS

sizes
    Pointer to a struct mlx5dv_export_sizes to be filled.

  mlx5dv_export_sizes

var_attrs_size
    Buffer size required for mlx5dv_var_export() / mlx5dv_var_import().

devx_umem_attrs_size
    Buffer size required for mlx5dv_devx_umem_export() / mlx5dv_devx_umem_import().

devx_obj_attrs_size
    Buffer size required for mlx5dv_devx_obj_export() / mlx5dv_devx_obj_import().
