+       The visorbus driver is a virtualized bus for the Unisys s-Par firmware.
+       Virtualized devices allow Linux guests on a system to share disks and
+       network cards that do not have SR-IOV support, and to be accessed using
+       the partition desktop application. The visorbus driver is required to
+       discover devices on an s-Par guest, and must be present for any other
+       s-Par guest driver to function correctly.

-       If you say Y here, you will enable the Unisys visorinput driver.
+       The Unisys s-Par visorinput driver provides a virtualized system
+       console (keyboard and mouse) that is accessible through the
+       s-Par firmware's user interface. s-Par provides video using the EFI
+       GOP protocol, so If this driver is not present, the Linux guest should
+       still boot with visible output in the partition desktop, but keyboard
+       and mouse interaction will not be available.
