Should obtain origin by calling hb_mc_config_get_origin(cfg) or hb_mc_config_get_origin_vcore(cfg), which is set by machine variables BSG_MACHINE_ORIGIN_COORD_X and BSG_MACHINE_ORIGIN_COORD_Y:

Also, the following pod_id parameter names are inaccurate, should be pod instead since they are coordinates, not indices
