This series adds the OPFN feature, which is used as the negotiation protocol by TID RDMA. This adds a totally hidden, in-band negotiation transfer that happens on the consumer's queue pair but without the consumer's knowledge. For that reason, things like completions for OPFN transfers must be filtered out of the completion queue and not sent to the consumer. This feature does not impact any consumer APIs, but does impact the driver/driver wire API. At a high level OPFN enables exchanging parameters between two hosts using IB compare and swap requests to a special virtual address. The request uses a reserved IB work request opcode (see patch 3). * opfn: IB/hfi1: Add static trace for OPFN IB/hfi1: Integrate OPFN into RC transactions IB/hfi1, IB/rdmavt: Allow for extending of QP's s_ack_queue IB/hfi1: OPFN interface IB/hfi1: Add OPFN helper functions for TID RDMA feature IB/hfi1: OPFN support discovery Signed-off-by: Doug Ledford <dledford@redhat.com>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
