     * Accepted as the {@code param_name} parameter of {@link CL10#clGetDeviceInfo GetDeviceInfo}. Returns a description of the topology used to connect the device to the
     * host, using the following 32-bytes union of structures:
     * 
     *      * typedef union
     * {

     * } cl_device_topology_amd;
     * 
     * The type of the structure returned can be queried by reading the first unsigned int of the returned data. The developer can use this type to cast the
     * returned union into the right structure type.
     * 
     * Currently, the only supported type in the structure above is {@link #CL_DEVICE_TOPOLOGY_TYPE_PCIE_AMD DEVICE_TOPOLOGY_TYPE_PCIE_AMD}. The information returned contains the PCI
     * Bus/Device/Function of the device, and is similar to the result of the lspci command in Linux. It enables the developer to match between the OpenCL
     * device ID and the physical PCI connection of the card.
