The "root" device search was introduced to support SMN access for Zen systems. This device represents a PCIe root complex. It is not the same as the "CPU/node" devices found at slots 0x18-0x1F. There may be multiple PCIe root complexes within an AMD node. Such is the case with server or High-end Desktop (HEDT) systems, etc. Therefore it is not enough to assume "root <-> AMD node" is a 1-to-1 association. Currently, this is handled by skipping "extra" root complexes during the search. However, the hardware provides the PCI bus number of an AMD node's root device. Use the hardware info to get the root device's bus and drop the extra search code and PCI IDs.

README
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 reStructuredText 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.
