 | 	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. |
