353 | Tests to see if this driver supports a given controller. If a child device is provided,\r | |
354 | it further tests to see if this driver supports creating a handle for the specified child device.\r | |
355 | \r | |
356 | This function checks to see if the driver specified by This supports the device specified by\r | |
357 | ControllerHandle. Drivers will typically use the device path attached to\r | |
358 | ControllerHandle and/or the services from the bus I/O abstraction attached to\r | |
359 | ControllerHandle to determine if the driver supports ControllerHandle. This function\r | |
360 | may be called many times during platform initialization. In order to reduce boot times, the tests\r | |
361 | performed by this function must be very small, and take as little time as possible to execute. This\r | |
362 | function must not change the state of any hardware devices, and this function must be aware that the\r | |
363 | device specified by ControllerHandle may already be managed by the same driver or a\r | |
364 | different driver. This function must match its calls to AllocatePages() with FreePages(),\r | |
365 | AllocatePool() with FreePool(), and OpenProtocol() with CloseProtocol().\r | |
366 | Since ControllerHandle may have been previously started by the same driver, if a protocol is\r | |
367 | already in the opened state, then it must not be closed with CloseProtocol(). This is required\r | |
368 | to guarantee the state of ControllerHandle is not modified by this function.\r | |

370 | @param[in] This A pointer to the EFI_DRIVER_BINDING_PROTOCOL instance.\r | |
371 | @param[in] ControllerHandle The handle of the controller to test. This handle\r | |
372 | must support a protocol interface that supplies\r | |
373 | an I/O abstraction to the driver.\r | |
374 | @param[in] RemainingDevicePath A pointer to the remaining portion of a device path. This\r | |
375 | parameter is ignored by device drivers, and is optional for bus\r | |
376 | drivers. For bus drivers, if this parameter is not NULL, then\r | |
377 | the bus driver must determine if the bus controller specified\r | |

504 | As a result, much of the error checking on the parameters to Start() has been moved into this\r | |
505 | common boot service. It is legal to call Start() from other locations,\r | |
506 | but the following calling restrictions must be followed or the system behavior will not be deterministic.\r | |
507 | 1. ControllerHandle must be a valid EFI_HANDLE.\r | |
508 | 2. If RemainingDevicePath is not NULL, then it must be a pointer to a naturally aligned\r | |
509 | EFI_DEVICE_PATH_PROTOCOL.\r | |
510 | 3. Prior to calling Start(), the Supported() function for the driver specified by This must\r | |
511 | have been called with the same calling parameters, and Supported() must have returned EFI_SUCCESS.\r | |
512 | \r | |
513 | @param[in] This A pointer to the EFI_DRIVER_BINDING_PROTOCOL instance.\r | |
514 | @param[in] ControllerHandle The handle of the controller to start. This handle\r | |
515 | must support a protocol interface that supplies\r | |
516 | an I/O abstraction to the driver.\r | |
517 | @param[in] RemainingDevicePath A pointer to the remaining portion of a device path. This\r | |
518 | parameter is ignored by device drivers, and is optional for bus\r | |
519 | drivers. For a bus driver, if this parameter is NULL, then handles\r | |
520 | for all the children of Controller are created by this driver.\r | |
521 | If this parameter is not NULL and the first Device Path Node is\r | |
522 | not the End of Device Path Node, then only the handle for the\r | |
523 | child device specified by the first Device Path Node of\r | |
524 | RemainingDevicePath is created by this driver.\r | |
525 | If the first Device Path Node of RemainingDevicePath is\r | |
