mlx5dv_get_export_sizes3
Query export buffer sizes for mlx5 objects
Usage
-
#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);
Overview
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
