Subject: [PATCH for-next v3 00/10] RDMA/rxe: Implement support for nonlinear packets
Date: Thu, 27 Jul 2023 15:01:19 -0500 [thread overview]
Message-ID: <20230727200128.65947-1-rpearsonhpe@gmail.com> (raw)
This patch set is a revised version of an older set which implements
support for nonlinear or fragmented packets. This avoids extra copies
in both the send and receive paths and gives significant performance
improvement for large messages such as are used in storage applications.
This patch set has been heavily tested at large system scale and
demonstrated a 2X improvement in file system read performance on
a 200 Gb/sec network.
The patch set is rebased to the current for-next branch with the
following previous patch sets applied:
RDMA/rxe: Fix incomplete state save in rxe_requester
RDMA/rxe: Misc fixes and cleanups
Enable rcu locking of verbs objects
RDMA/rxe: Misc cleanups
Bob Pearson (10):
RDMA/rxe: Add sg fragment ops
RDMA/rxe: Extend rxe_mr_copy to support skb frags
RDMA/rxe: Extend copy_data to support skb frags
RDMA/rxe: Extend rxe_init_packet() to support frags
RDMA/rxe: Extend rxe_icrc.c to support frags
RDMA/rxe: Extend rxe_init_req_packet() for frags
RDMA/rxe: Extend response packets for frags
RDMA/rxe: Extend send/write_data_in() for frags
RDMA/rxe: Extend do_read() in rxe_comp.c for frags
RDMA/rxe: Enable sg code in rxe
