/*
* @brief
* Gets rsync (GEN-ID) register information associated with the supported
* NPUs.
*
* The caller would use the returned information {GPU device, NPU device,
* socket-id, cluster-id} to pick the optimal generation registers to issue
* RSYNC (NVLink HW flush).
*
* The interface allocates structures to return the information, hence
* nvidia_p2p_put_rsync_registers() must be called to free the structures.
*
* Note, cluster-id is hardcoded to zero as early system configurations would
* only support cluster mode i.e. all devices would share the same cluster-id
* (0). In the future, appropriate kernel support would be needed to query
* cluster-ids.
*
* @param[out] reg_info
* A pointer to the rsync reg info structure.
* This interface is no longer supported and will always return an error. It
* is left in place (for now) to allow third-party callers to build without
* any errors.
*
* @Returns
* 0 Upon successful completion. Otherwise, returns negative value.
* -ENODEV
