	  Kernel-level support for the Direct Rendering Infrastructure (DRI)
	  introduced in XFree86 4.0. If you say Y here, you need to select
	  the module that's right for your graphics card from the list below.
	  These modules provide support for synchronization, security, and
	  DMA transfers. Please see <http://dri.sourceforge.net/> for more
	  details.  You should also select and configure AGP
	  (/dev/agpgart) support if it is available for your platform.

	  Say Y here, if you want to use EDID data to be loaded from the
	  /lib/firmware directory or one of the provided built-in
	  data sets. This may be necessary, if the graphics adapter or
	  monitor are unable to provide appropriate EDID data. Since this
	  feature is provided as a workaround for broken hardware, the
	  default case is N. Details and instructions how to build your own
	  EDID data are given in Documentation/EDID/HOWTO.txt.

	depends on DRM && MMU
	select DRM_VM
	help
	  Enable legacy DRI1 drivers. Those drivers expose unsafe and dangerous
	  APIs to user-space, which can be used to circumvent access
	  restrictions and other security measures. For backwards compatibility
	  those drivers are still available, but their use is highly
	  inadvisable and might harm your system.

	  You are recommended to use the safe modeset-only drivers instead, and
	  perform 3D emulation in user-space.

	  Unless you have strong reasons to go rogue, say "N".
