126 | Tests to see if this driver supports a given controller. If a child device is provided,\r | |

128 | \r | |
129 | This function checks to see if the driver specified by This supports the device specified by\r | |
130 | ControllerHandle. Drivers will typically use the device path attached to\r | |
131 | ControllerHandle and/or the services from the bus I/O abstraction attached to\r | |
132 | ControllerHandle to determine if the driver supports ControllerHandle. This function\r | |
133 | may be called many times during platform initialization. In order to reduce boot times, the tests\r | |
134 | performed by this function must be very small, and take as little time as possible to execute. This\r | |
135 | function must not change the state of any hardware devices, and this function must be aware that the\r | |
136 | device specified by ControllerHandle may already be managed by the same driver or a\r | |
137 | different driver. This function must match its calls to AllocatePages() with FreePages(),\r | |
138 | AllocatePool() with FreePool(), and OpenProtocol() with CloseProtocol().\r | |
139 | Since ControllerHandle may have been previously started by the same driver, if a protocol is\r | |
140 | already in the opened state, then it must not be closed with CloseProtocol(). This is required\r | |
