392 | Tests to see if this driver supports a given controller. If a child device is provided, \r | |

394 | \r | |
395 | This function checks to see if the driver specified by This supports the device specified by \r | |
396 | ControllerHandle. Drivers will typically use the device path attached to \r | |
397 | ControllerHandle and/or the services from the bus I/O abstraction attached to \r | |
398 | ControllerHandle to determine if the driver supports ControllerHandle. This function \r | |
399 | may be called many times during platform initialization. In order to reduce boot times, the tests \r | |
400 | performed by this function must be very small, and take as little time as possible to execute. This \r | |
401 | function must not change the state of any hardware devices, and this function must be aware that the \r | |
402 | device specified by ControllerHandle may already be managed by the same driver or a \r | |
403 | different driver. This function must match its calls to AllocatePages() with FreePages(), \r | |
404 | AllocatePool() with FreePool(), and OpenProtocol() with CloseProtocol(). \r | |
405 | Since ControllerHandle may have been previously started by the same driver, if a protocol is \r | |

410 | @param[in] ControllerHandle The handle of the controller to test. This handle \r | |
411 | must support a protocol interface that supplies \r | |
412 | an I/O abstraction to the driver.\r | |
413 | @param[in] RemainingDevicePath A pointer to the remaining portion of a device path. This \r | |
414 | parameter is ignored by device drivers, and is optional for bus \r | |
415 | drivers. For bus drivers, if this parameter is not NULL, then \r | |
416 | the bus driver must determine if the bus controller specified \r | |
