| Benjamin Romer | f84a187 | 2015-11-24 09:53:29 -0500 | [diff] [blame] | 10 | The visorbus driver is a virtualized bus for the Unisys s-Par firmware. |
| 11 | Virtualized devices allow Linux guests on a system to share disks and |
| 12 | network cards that do not have SR-IOV support, and to be accessed using |
| 13 | the partition desktop application. The visorbus driver is required to |
| 14 | discover devices on an s-Par guest, and must be present for any other |
| 15 | s-Par guest driver to function correctly. |
