| Tests to see if this driver supports a given controller. If a child device is provided, | |
| it further tests to see if this driver supports creating a handle for the specified child device. | |
| This function checks to see if the driver specified by This supports the device specified by | |
| ControllerHandle. Drivers will typically use the device path attached to | |
| ControllerHandle and/or the services from the bus I/O abstraction attached to | |
| ControllerHandle to determine if the driver supports ControllerHandle. This function | |
| may be called many times during platform initialization. In order to reduce boot times, the tests | |
| performed by this function must be very small, and take as little time as possible to execute. This | |
| function must not change the state of any hardware devices, and this function must be aware that the | |
| device specified by ControllerHandle may already be managed by the same driver or a | |
| different driver. This function must match its calls to AllocatePages() with FreePages(), | |
| AllocatePool() with FreePool(), and OpenProtocol() with CloseProtocol(). | |
| Since ControllerHandle may have been previously started by the same driver, if a protocol is | |
| already in the opened state, then it must not be closed with CloseProtocol(). This is required | |
| to guarantee the state of ControllerHandle is not modified by this function. | |
| @param[in] This A pointer to the EFI_DRIVER_BINDING_PROTOCOL instance. | |
| @param[in] ControllerHandle The handle of the controller to test. This handle | |
| must support a protocol interface that supplies | |
| an I/O abstraction to the driver. | |

| parameter is ignored by device drivers, and is optional for bus | |
| drivers. For bus drivers, if this parameter is not NULL, then | |
| the bus driver must determine if the bus controller specified | |
| by ControllerHandle and the child controller specified | |
| by RemainingDevicePath are both supported by this | |
| bus driver. | |
