Why This File Exists

Repeatable hardware-adapter layer. Deep compatibility for every driver is out of scope; this atlas records patterns, probe lifecycles, bus glue, IRQ/DMA usage, and links back to core abstractions.

	  Support for Nouveau platform driver, used for SoC GPUs as found
	  on NVIDIA Tegra K1.

config NOUVEAU_DEBUG
	int "Maximum debug level"
	depends on DRM_NOUVEAU
	range 0 7
	default 5
	help
	  Selects the maximum debug level to compile support for.

	  0 - fatal
	  1 - error
	  2 - warning
	  3 - info
	  4 - debug
	  5 - trace (recommended)
	  6 - paranoia
	  7 - spam

	  The paranoia and spam levels will add a lot of extra checks which
	  may potentially slow down driver operation.

config NOUVEAU_DEBUG_DEFAULT
	int "Default debug level"
	depends on DRM_NOUVEAU
	range 0 7
	default 3
	help
	  Selects the default debug level
