+config DIBS
+	tristate "Direct Internal Buffer Sharing support"
+	default n
+	help
+	  Direct Internal Buffer Sharing (DIBS) is a communication method that
+	  uses common physical (internal) memory for synchronous direct access
+	  into a remote buffer.
+
+	  Select this option to provide the abstraction layer between
+	  dibs devices and dibs clients like the SMC protocol.
+	  The module name is dibs.

+config DIBS_LO
+	bool "Intra-OS shortcut with dibs loopback"
+	depends on DIBS
+	default n
+	help
+	  DIBS_LO enables the creation of an software-emulated dibs device
+	  named lo which can be used for transferring data when communication
+	  occurs within the same OS. This helps in convenient testing of
+	  dibs clients, since dibs loopback is independent of architecture or
+	  hardware.
