Subject: [PATCH rdma-next 00/10] RDMA/mana_ib: Add kernel RC and fast registration support
Date: Thu, 1 Oct 2026 11:20:05 -0700 [thread overview]
Message-ID: <20261001182015.1757203-1-kotaranov@linux.microsoft.com> (raw)
From: Konstantin Taranov <kotaranov@microsoft.com>
Add kernel RC QPs and fast-registration MRs to the MANA RDMA driver
for kernel consumers such as NVMe/RDMA and NFS/RDMA.
Implement QP creation and state management, work request posting,
completion processing, error handling, and queue draining. Kernel RC
QPs require extended-WQE and power-of-two-SQ hardware support.
Tested with krping, NVMe/RDMA, and NFS/RDMA, including RC send and
receive error recovery with krping and NVMe/RDMA.
Konstantin Taranov (10):
RDMA/mana_ib: Allocate and map fast-registration MRs
RDMA/mana: Create and destroy kernel RC QPs
net/mana: Extend GDMA encoding for new RDMA WQEs
RDMA/mana_ib: Maintain kernel RC QP state
RDMA/mana_ib: Post receive WRs on kernel RC QPs
RDMA/mana_ib: Post send and memory-management WRs on RC QPs
RDMA/mana_ib: Poll RC completions using PSN and FSN progress
RDMA/mana_ib: Flush and notify CQs when kernel QPs enter ERR
RDMA/mana_ib: Handle error CQEs for RC QPs
RDMA/mana_ib: Drain kernel receive and send queues
