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.

menuconfig LOGO
	bool "Bootup logo"
	depends on FB_CORE || SGI_NEWPORT_CONSOLE
	help
	  Enable and select frame buffer bootup logos.
	  Monochrome logos will also be used by the DRM panic handler, if
	  enabled.

	help
	  Takes a path to a monochromatic logo in the portable pixmap file
	  format (.pbm). This defaults to the Tux penguin.

	  For example, the below ImageMagick command can be used to reduce
	  an image to black and white and convert it into a pbm file:

	    magick source_image -compress none destination.pbm

	help
	  Takes a path to a logo in the portable pixmap file format (.ppm),
	  using the 16 colors from the drivers/video/logo/clut_vga16.ppm
	  palette. This defaults to the Tux penguin.

	  For example, the below ImageMagick command can be used to reduce an
	  image to the VGA 16 colors palette and convert into a ppm file:

	    magick source_image -compress none \
	      -remap drivers/video/logo/clut_vga16.ppm destination.ppm
