Subject: [PATCH rdma v1 0/2] Add ZTE DingHai Ethernet Protocol Driver for RDMA
Date: Wed, 24 Jun 2026 16:44:57 +0800 (CST) [thread overview]
Message-ID: <202606241644572798vwNbZEAtt3c2IHcJUtCs@zte.com.cn> (raw)
From: Yanze Zhang <zhang.yanze@zte.com.cn>
This series adds initial RoCEv2 support for the ZTE ZXDH RNIC,
a PCIe Gen5 adapter.
The driver implements core IB verbs (QP/CQ/MR/SRQ/AH) with async CQP
command path and DCQCN congestion control, using the auxiliary bus
framework following hns/bnxt_re patterns. It does not include Ethernet
network data plane support. Perftest shows ~395 Gb/s write bandwidth at
4KB message size over RoCEv2 RC/UD QPs.
