Subject: [Patch v4 00/22] CIFS: Implement SMBDirect
Date: Sun, 1 Oct 2017 19:30:08 -0700 [thread overview]
Message-ID: <20171002023030.3582-1-longli@exchange.microsoft.com> (raw)
From: Long Li <longli@microsoft.com>
Starting with SMB2 dialect 3.0, Microsoft introduced SMBDirect transport
protocol for transferring upper layer (SMB2) payload over RDMA via Infiniband,
RoCE or iWARP. The prococol is published in [MS-SMBD]
(https://msdn.microsoft.com/en-us/library/hh536346.aspx).
Patch v2 added RDMA read/write via memory registration, and addressed
feedbacks on v1.
Patch v3 improved performance by introducing an additional queue for handling
empty packets and reducing lock contention on IRQ path. Also added light
weight profiling by reading TSC and addressed feedbacks on v2.
Patch v4 fixed connectivity issues with iWAPR devices and addressed comments.
