[openEuler/rdma-core v4] libhns: Support user to choose using UD sl or pktype to adapt MPI APP
by Chengchang Tang 09 Jun '23

09 Jun '23

From: Junxian Huang <huangjunxian6(a)hisilicon.com> driver inclusion category: bugfix bugzilla: https://gitee.com/src-openeuler/rdma-core/issues/I7A5YM --------------------------------------------------------------- According to Annex17_RoCEv2 (A17.4.5.2), for RoCEv2 UD, a CQE should carry a flag that indicates if the received frame is an IPv4, IPv6 or RoCE packet. But currently, the values of the flag corresponding to these packet types haven't been defined yet in WC. In UCX, 'sl' in ibv_wc for UD is used as the packet type flag, and the packet type values have already been defined in the UCX patch of https://github.com/openucx/ucx/commit/ed28845b88633e65d64fce8ec880060aa61bd… Therefore, to adapt UCX, add a create flag to hnsdv_create_qp() to allow users to choose whether they use 'sl' in ibv_wc as service level or packet type for UD. For the latter, obtain and translate the packet type from CQE and fill it to 'sl' in ibv_wc.
