mlx5_ib_map_mr_sg_pi() will map the PI and data dma mapped SG lists to the mlx5 memory region prior to the registration operation. In the new API, the mlx5 driver will allocate an internal memory region for the UMR operation to register both PI and data SG lists. The internal MR will use KLM mode in order to map 2 (possibly non-contiguous/non-align) SG lists using 1 memory key. In the new API, each ULP will use 1 memory region for the signature operation (instead of 3 in the old API). This memory region will have a key that will be exposed to remote server to perform RDMA operation. The internal memory key that will map the SG lists will stay private.

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.
