SMC supports two variants: SMC-R and SMC-D. For data transport, SMC-R uses RDMA devices, SMC-D uses so-called Internal Shared Memory (ISM) devices. An ISM device only allows shared memory communication between SMC instances on the same machine. For example, this allows virtual machines on the same host to communicate via SMC without RDMA devices. This patch adds the base infrastructure for SMC-D and ISM devices to the existing SMC code. It contains the following: * ISM driver interface: This interface allows an ISM driver to register ISM devices in SMC. In the process, the driver provides a set of device ops for each device. SMC uses these ops to execute SMC specific operations on or transfer data over the device. * Core SMC-D link group, connection, and buffer support: Link groups, SMC connections and SMC buffers (in smc_core) are extended to support SMC-D. * SMC type checks: Some type checks are added to prevent using SMC-R specific code for SMC-D and vice versa. To actually use SMC-D, additional changes to pnetid, CLC, CDC, etc. are required. These are added in follow-up patches.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
