| 9bc88ad8 | 3 | A UI application to offer a UI interface in device manager to let user configure\r |
| a6f164a7 | 4 | platform override protocol to override the default algorithm for matching\r |
| 5 | drivers to controllers.\r | |
| 6 | \r | |
| 7 | The main flow:\r | |
| 68dbca6c LG |
8 | 1. The UI application dynamicly locate all controller device path.\r |
| 9 | 2. The UI application dynamicly locate all drivers which support binding protocol.\r | |
| 10 | 3. The UI application export and dynamicly update two menu to let user select the\r | |
| a6f164a7 | 11 | mapping between drivers to controllers.\r |
| 68dbca6c | 12 | 4. The UI application save all the mapping info in NV variables which will be consumed\r |
| a6f164a7 | 13 | by platform override protocol driver to publish the platform override protocol.\r |
