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

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

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