308 Tests to see if this driver supports a given controller. If a child device is provided,\r
309 it further tests to see if this driver supports creating a handle for the specified child device.\r
310\r
311 This function checks to see if the driver specified by This supports the device specified by\r
312 ControllerHandle. Drivers will typically use the device path attached to\r
313 ControllerHandle and/or the services from the bus I/O abstraction attached to\r
314 ControllerHandle to determine if the driver supports ControllerHandle. This function\r
315 may be called many times during platform initialization. In order to reduce boot times, the tests\r
316 performed by this function must be very small, and take as little time as possible to execute. This\r
317 function must not change the state of any hardware devices, and this function must be aware that the\r
318 device specified by ControllerHandle may already be managed by the same driver or a\r
319 different driver. This function must match its calls to AllocatePages() with FreePages(),\r
320 AllocatePool() with FreePool(), and OpenProtocol() with CloseProtocol().\r
321 Because ControllerHandle may have been previously started by the same driver, if a protocol is\r
322 already in the opened state, then it must not be closed with CloseProtocol(). This is required\r
323 to guarantee the state of ControllerHandle is not modified by this function.\r

330 parameter is ignored by device drivers, and is optional for bus\r
331 drivers. For bus drivers, if this parameter is not NULL, then\r
