23 | Tests to see if this driver supports a given controller. If a child device is provided,\r | |
24 | it further tests to see if this driver supports creating a handle for the specified child device.\r | |
25 | \r | |
26 | This function checks to see if the driver specified by This supports the device specified by\r | |
27 | ControllerHandle. Drivers will typically use the device path attached to\r | |
28 | ControllerHandle and/or the services from the bus I/O abstraction attached to\r | |
29 | ControllerHandle to determine if the driver supports ControllerHandle. This function\r | |
30 | may be called many times during platform initialization. In order to reduce boot times, the tests\r | |
31 | performed by this function must be very small, and take as little time as possible to execute. This\r | |
32 | function must not change the state of any hardware devices, and this function must be aware that the\r | |
33 | device specified by ControllerHandle may already be managed by the same driver or a\r | |
34 | different driver. This function must match its calls to AllocatePages() with FreePages(),\r | |
35 | AllocatePool() with FreePool(), and OpenProtocol() with CloseProtocol().\r | |
36 | Because ControllerHandle may have been previously started by the same driver, if a protocol is\r | |
37 | already in the opened state, then it must not be closed with CloseProtocol(). This is required\r | |
38 | to guarantee the state of ControllerHandle is not modified by this function.\r | |
39 | \r | |
40 | @param[in] This A pointer to the EFI_DRIVER_BINDING_PROTOCOL instance.\r | |
41 | @param[in] ControllerHandle The handle of the controller to test. This handle\r | |
42 | must support a protocol interface that supplies\r | |
43 | an I/O abstraction to the driver.\r | |
44 | @param[in] RemainingDevicePath A pointer to the remaining portion of a device path. This\r | |
45 | parameter is ignored by device drivers, and is optional for bus\r | |
46 | drivers. For bus drivers, if this parameter is not NULL, then\r | |
47 | the bus driver must determine if the bus controller specified\r | |
48 | by ControllerHandle and the child controller specified\r | |
49 | by RemainingDevicePath are both supported by this\r | |
50 | bus driver.\r | |
