The psp supplies the link type in the upper 2 bits of the psp xgmi node information num_hops field. With a new link type, Aldebaran has these bits set to a non-zero value (1 = xGMI3) so the KFD topology will report the incorrect IO link weights without proper masking. The actual number of hops is located in the 3 least significant bits of this field so mask if off accordingly before passing it to the KFD.

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.
