For CONFIG_DRM_USE_DYNAMIC_DEBUG=y, wrap __drm_dbg() & __drm_dev_dbg() in one of dyndbg's Factory macros: _dynamic_func_call_no_desc(). This adds the callsite descriptor into the code, and an entry for each into /proc/dynamic_debug/control. #> echo class DRM_UT_ATOMIC +p > /proc/dynamic_debug/control CONFIG_DRM_USE_DYNAMIC_DEBUG=y/n is configurable because of the .data footprint cost of per-callsite control; 56 bytes/site * ~2k for i915, ~4k callsites for amdgpu. This is large enough that a kernel builder might not want it.

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 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.
