  9	 Use dynamic-debug to avoid drm_debug_enabled() runtime overheads.
 10	 Due to callsite counts in DRM drivers (~4k in amdgpu) and 56
 11	 bytes per callsite, the .data costs can be substantial, and
 12	 are therefore configurable.

 19	help
 20	  A kernel build should not cause any compiler warnings, and this
 21	  enables the '-Werror' flag to enforce that rule in the drm subsystem.
 22
 23	  The drm subsystem enables more warnings than the kernel default, so
 24	  this config option is disabled by default.

 34	  include/drm compile, are self-contained, have header guards, and have
 35	  no kernel-doc warnings.

 97	  Enables unit tests for TTM, a GPU memory manager subsystem used
 98	  to manage memory buffers. This option is mostly useful for kernel
 99	  developers. It depends on (UML || COMPILE_TEST) since no other driver
100	  which uses TTM can be loaded while running the tests.
