Traditional IB path records have 16 bit SLID and DLID fields that cannot really be used by applications and ULPs working with 32-bit LIDs. OPA path records add support for 32 bit SLIDs and DLIDs. Support for OPA path records is specified by bit 26 of the capmask2 field in the OPA class portinfo. Note that these patches apply on the earlier patch series with subject "[PATCH v2 rdma-next 00/18] Enhance ib_ah_attr to specify types" Changes from v1: --------------- * Remove an unneeded change that was introduced in ulp/srpt/ib_srpt.c This patches are organized as follows: * Patch 1 performs checkpatch fixes that later patches touch upon. * Patch 2 renames ib_sa_path_rec to sa_path_rec * Patch 3 introduces the 'rec_type' field that identifies a path record type. This field replaces the existing 'gid_type' field. * Patch 4 splits the existing sa_path_rec into a union of sa_path_rec_ib and sa_path_rec_roce structures. Fields that are common to both continue to be part of sa_path_rec. * Patch 5 extends sa_path_rec to have path records of type opa * Patch 6 enables SA component to query for OPA path records if ULPs and other kernel components request for it Dasaratharaman Chandramouli (6): IB/CM: Add braces when using sizeof IB/SA: Rename ib_sa_path_rec to sa_path_rec IB/SA: Introduce path record specific types IB/SA: Split struct sa_path_rec based on IB and ROCE specific fields IB/SA: Add OPA path record type IB/SA: Add support to query OPA path records drivers/infiniband/core/cm.c | 103 ++++++---- drivers/infiniband/core/cma.c | 50 +++-- drivers/infiniband/core/sa_query.c | 320 ++++++++++++++++++++++++++---- drivers/infiniband/core/ucm.c | 6 +- drivers/infiniband/core/ucma.c | 24 ++- drivers/infiniband/core/uverbs_marshall.c | 52 +++-- drivers/infiniband/ulp/ipoib/ipoib.h | 2 +- drivers/infiniband/ulp/ipoib/ipoib_cm.c | 6 +- drivers/infiniband/ulp/ipoib/ipoib_fs.c | 6 +- drivers/infiniband/ulp/ipoib/ipoib_main.c | 22 +- drivers/infiniband/ulp/srp/ib_srp.c | 13 +- drivers/infiniband/ulp/srp/ib_srp.h | 2 +- include/rdma/ib_cm.h | 14 +- include/rdma/ib_mad.h | 13 ++ include/rdma/ib_marshall.h | 4 +- include/rdma/ib_sa.h | 287 +++++++++++++++++++++++++-- include/rdma/opa_addr.h | 79 ++++++++ include/rdma/rdma_cm.h | 2 +- include/rdma/rdma_cm_ib.h | 2 +- 19 files changed, 847 insertions(+), 160 deletions(-) create mode 100644 include/rdma/opa_addr.h -- 1.8.3.1 -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
