Abstract:
|
|
|
|
A UI driver to offer a UI interface in device manager to let user configue
|
|
platform override protocol to override the default algorithm for matching
|
|
drivers to controllers.
|
|
|
|
The main flow:
|
|
1. The UI driver dynamicly locate all controller device path.
|
|
2. The UI driver dynamicly locate all drivers which support binding protocol.
|
|
3. The UI driver export and dynamicly update two menu to let user select the
|
|
mapping between drivers to controllers.
|
|
4. The UI driver save all the mapping info in NV variables which will be consumed
|
|
by platform override protocol driver to publish the platform override protocol.
