For selftest purposes, add __pr_debug_cls(class, fmt, ...) I didn't think we'd need to define this, since DRM effectively has it already in drm_dbg, drm_devdbg. But test_dynamic_debug needs it in order to demonstrate all the moving parts. Note the __ prefix; its not intended for general use, at least until a need emerges. ISTM the drm.debug model (macro wrappers inserting enum const 1st arg) is the baseline approach. That said, nouveau might want it for easy use in its debug macros. TBD. NB: it does require a builtin-constant class, __pr_debug_cls(i++, ...) is disallowed by compiler.

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.
