The debugfs code was intended to aid figuring out functionality of undocumented registers. Turns out that wasn't very helpful, since register locations change too much between AMD chip revisions, and the data isn't really valuable for chips where it isn't already supported. On top of that, its existence has been used as argument for providing pseudo-API debugfs functions in other drivers. So let's just take it out. Signed-off-by: Guenter Roeck <linux@roeck-us.net>
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.
