For special scenarios, such as after the PCIe PHY is bifurcation and with different usage like phy1 is the RC and the other phy0 is the EP. Since the EP has been initialized in the previous stage, it is not expected that repeated initialization in the kernel stage will cause the link to be disconnected. Therefore, no matter which of the two controllers performs initialization, the PHY re-initialization operation should be avoided.

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.
