147 Tests to see if this driver supports a given controller. If a child device is provided,\r
148 it further tests to see if this driver supports creating a handle for the specified child device.\r
149\r
150 This function checks to see if the driver specified by This supports the device specified by\r
151 ControllerHandle. Drivers will typically use the device path attached to\r
152 ControllerHandle and/or the services from the bus I/O abstraction attached to\r
153 ControllerHandle to determine if the driver supports ControllerHandle. This function\r
154 may be called many times during platform initialization. In order to reduce boot times, the tests\r
155 performed by this function must be very small, and take as little time as possible to execute. This\r
156 function must not change the state of any hardware devices, and this function must be aware that the\r
157 device specified by ControllerHandle may already be managed by the same driver or a\r
158 different driver. This function must match its calls to AllocatePages() with FreePages(),\r
159 AllocatePool() with FreePool(), and OpenProtocol() with CloseProtocol().\r
160 Since ControllerHandle may have been previously started by the same driver, if a protocol is\r
161 already in the opened state, then it must not be closed with CloseProtocol(). This is required\r
162 to guarantee the state of ControllerHandle is not modified by this function.\r
163\r
164 @param[in] This A pointer to the EFI_DRIVER_BINDING_PROTOCOL instance.\r
165 @param[in] ControllerHandle The handle of the controller to test. This handle\r
166 must support a protocol interface that supplies\r
167 an I/O abstraction to the driver.\r
168 @param[in] RemainingDevicePath A pointer to the remaining portion of a device path. This\r
169 parameter is ignored by device drivers, and is optional for bus\r
170 drivers. For bus drivers, if this parameter is not NULL, then\r
171 the bus driver must determine if the bus controller specified\r
172 by ControllerHandle and the child controller specified\r
173 by RemainingDevicePath are both supported by this\r
174 bus driver.\r
175\r
176 @retval EFI_SUCCESS The device specified by ControllerHandle and\r
