+## Interface for userspace drivers
+
+We need to provide an interface suitable for implementing drivers in
+userspace:
+
+* A way to handle interrupts
+* and a way to allocate memory suitable for DMA buffers
+
+### Required ABI changes
+
+None. This is a new interface. Debian/Hurd uses a non-standard rpc
+id, so we do not change an existing procedure there.
+
+### Status
+
+A DDE-based solution is used in Debian/Hurd to provide network
+drivers. A rump kernel prototype is implemented. These use a kernel
+interface written by Zheng Da available in the
+"master-user_level_drivers" branch in the GNU Mach repository.
