+         Platform driver for Userspace I/O devices, including generic
+         interrupt handling code. Shared interrupts are not supported.
+
+         This kernel driver requires that the matching userspace driver
+         handles interrupts in a special way. Userspace is responsible
+         for acknowledging the hardware device if needed, and re-enabling
+         interrupts in the interrupt controller using the write() syscall.
