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. config DRM_MIPI_DSI	bool	depends on DRM config DRM_DP_AUX_CHARDEV	bool "DRM DP AUX Interface"	depends on DRM	help	  Choose this option to enable a /dev/drm_dp_auxN node that allows to	  read and write values to arbitrary DPCD registers on the DP aux	  channel. config DRM_DEBUG_MM	bool "Insert extra checks and debug info into the DRM range managers"	default n	depends on DRM=y	depends on STACKTRACE_SUPPORT	select STACKDEPOT	help	  Enable allocation tracking of memory manager and leak detection on	  shutdown.

If in doubt, say "Y". config DRM_FBDEV_OVERALLOC	int "Overallocation of the fbdev buffer"	depends on DRM_FBDEV_EMULATION	default 100	help	  Defines the fbdev buffer overallocation in percent. Default	  is 100. Typical values for double buffering will be 200,	  triple buffering 300. config DRM_LOAD_EDID_FIRMWARE	bool "Allow to specify an EDID data set instead of probing for it"	depends on DRM_KMS_HELPER	help	  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. config DRM_TTM	tristate	depends on DRM && MMU	help	  GPU memory management subsystem for devices with multiple	  GPU memory types.

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". if DRM_LEGACY config DRM_TDFX	tristate "3dfx Banshee/Voodoo3+"	depends on DRM && PCI	help	  Choose this option if you have a 3dfx Banshee or Voodoo3 (or later),	  graphics card.
