Hal, I could be wrong, but as I understand it, this function does not permit the user to request more than one path. The API takes a query request which contains pair of lids or guids, but does not have a field for specifying the number of paths.

I think a better approach is as follows: 1. Set num_paths in the application(s) as desired 2. In the library, check for num_paths 0 or not. If not, then set the numbpath compmask bit. -- Hal > --- osm_vendor_ibumad_sa.bak 2008-12-10 13:21:22.000000000 -0500 > +++ osm_vendor_ibumad_sa.c 2008-12-10 13:24:42.000000000 -0500 > @@ -615,7 +615,7 @@ > sa_mad_data.attr_offset = > ib_get_attr_offset(sizeof(ib_path_rec_t)); > sa_mad_data.comp_mask = > - (IB_PR_COMPMASK_DGID | IB_PR_COMPMASK_SGID); > + (IB_PR_COMPMASK_DGID | IB_PR_COMPMASK_SGID | > IB_PR_COMPMASK_NUMBPATH); > sa_mad_data.p_attr = &path_rec; > ib_gid_set_default(&path_rec.dgid, > ((osmv_guid_pair_t *) > (p_query_req-> @@ -625,6 +625,7 @@ > ((osmv_guid_pair_t *) (p_query_req-> > p_query_input))-> > src_guid); > + path_rec.num_path = 1; > break; > > case OSMV_QUERY_PATH_REC_BY_GIDS: > @@ -634,7 +635,7 @@ > sa_mad_data.attr_offset = > ib_get_attr_offset(sizeof(ib_path_rec_t)); > sa_mad_data.comp_mask = > - (IB_PR_COMPMASK_DGID | IB_PR_COMPMASK_SGID); > + (IB_PR_COMPMASK_DGID | IB_PR_COMPMASK_SGID | > IB_PR_COMPMASK_NUMBPATH); > sa_mad_data.p_attr = &path_rec; > memcpy(&path_rec.dgid, > &((osmv_gid_pair_t *) > (p_query_req->p_query_input))-> @@ -642,6 +643,7 @@ > memcpy(&path_rec.sgid, > &((osmv_gid_pair_t *) (p_query_req->p_query_input))-> > src_gid, sizeof(ib_gid_t)); > + path_rec.num_path = 1; > break; > > case OSMV_QUERY_PATH_REC_BY_LIDS: > @@ -652,13 +654,14 @@ > sa_mad_data.attr_offset = > ib_get_attr_offset(sizeof(ib_path_rec_t)); > sa_mad_data.comp_mask = > - (IB_PR_COMPMASK_DLID | IB_PR_COMPMASK_SLID); > + (IB_PR_COMPMASK_DLID | IB_PR_COMPMASK_SLID | > IB_PR_COMPMASK_NUMBPATH); > sa_mad_data.p_attr = &path_rec; > path_rec.dlid = > ((osmv_lid_pair_t *) (p_query_req->p_query_input))-> > dest_lid; > path_rec.slid = > ((osmv_lid_pair_t *) > (p_query_req->p_query_input))->src_lid; > + path_rec.num_path = 1; > break; > > case OSMV_QUERY_UD_MULTICAST_SET: > --- osm_vendor_mlx_sa.bak 2008-12-10 13:21:10.000000000 -0500 > +++ osm_vendor_mlx_sa.c 2008-12-10 13:24:07.000000000 -0500 > @@ -743,7 +743,7 @@ > sa_mad_data.attr_offset = > ib_get_attr_offset(sizeof(ib_path_rec_t)); > sa_mad_data.comp_mask = > - (IB_PR_COMPMASK_DGID | IB_PR_COMPMASK_SGID); > + (IB_PR_COMPMASK_DGID | IB_PR_COMPMASK_SGID | > IB_PR_COMPMASK_NUMBPATH); > sa_mad_data.p_attr = &path_rec; > ib_gid_set_default(&path_rec.dgid, > ((osmv_guid_pair_t *) > (p_query_req-> @@ -753,6 +753,7 @@ > ((osmv_guid_pair_t *) (p_query_req-> > p_query_input))-> > src_guid); > + path_rec.num_path = 1; > break; > > case OSMV_QUERY_PATH_REC_BY_GIDS: > @@ -763,7 +764,7 @@ > sa_mad_data.attr_offset = > ib_get_attr_offset(sizeof(ib_path_rec_t)); > sa_mad_data.comp_mask = > - (IB_PR_COMPMASK_DGID | IB_PR_COMPMASK_SGID); > + (IB_PR_COMPMASK_DGID | IB_PR_COMPMASK_SGID | > IB_PR_COMPMASK_NUMBPATH); > sa_mad_data.p_attr = &path_rec; > memcpy(&path_rec.dgid, > &((osmv_gid_pair_t *) > (p_query_req->p_query_input))-> @@ -771,6 +772,7 @@ > memcpy(&path_rec.sgid, > &((osmv_gid_pair_t *) (p_query_req->p_query_input))-> > src_gid, sizeof(ib_gid_t)); > + path_rec.num_path = 1; > break; > > case OSMV_QUERY_PATH_REC_BY_LIDS: > @@ -789,6 +791,7 @@ > dest_lid; > path_rec.slid = > ((osmv_lid_pair_t *) > (p_query_req->p_query_input))->src_lid; > + path_rec.num_path = 1; > break; > > case OSMV_QUERY_UD_MULTICAST_SET: > > -- > Michael Heinz > Principal Engineer, Qlogic Corporation King of Prussia, Pennsylvania > > _______________________________________________ > general mailing list > [email protected] > http://lists.openfabrics.org/cgi-bin/mailman/listinfo/general > > To unsubscribe, please visit > http://openib.org/mailman/listinfo/openib-general > _______________________________________________ general mailing list [email protected] http://lists.openfabrics.org/cgi-bin/mailman/listinfo/general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
