Subject: [PATCH RFC 0/7] RDMA/hns: Add support for Dynamic Context Attachment
Date: Fri, 15 Jan 2021 18:22:11 +0800 [thread overview]
Message-ID: <1610706138-4219-1-git-send-email-liweihang@huawei.com> (raw)
The hip09 introduces the DCA(Dynamic Context Attachment) feature which
supports many RC QPs to share the WQE buffer in a memory pool. If a QP
enables DCA feature, the WQE's buffer will not be allocated when creating
but when the users start to post WRs. This will reduce the memory
consumption when there are too many QPs are inactive.
Xi Wang (7):
RDMA/hns: Introduce DCA for RC QP
RDMA/hns: Add method for shrinking DCA memory pool
RDMA/hns: Configure DCA mode for the userspace QP
RDMA/hns: Add method for attaching WQE buffer
RDMA/hns: Setup the configuration of WQE addressing to QPC
RDMA/hns: Add method to detach WQE buffer
RDMA/hns: Add method to query WQE buffer's address
