1332 | \r | |
f75a7f56 LG |
1333 | This function checks to see if the driver specified by This supports the device specified by\r |
1334 | ControllerHandle. Drivers typically use the device path attached to\r | |
1335 | ControllerHandle and/or the services from the bus I/O abstraction attached to\r | |
1336 | ControllerHandle to determine if the driver supports ControllerHandle. This function\r | |
1337 | may be called many times during platform initialization. In order to reduce boot times, the tests\r | |
1338 | performed by this function must be very small and take as little time as possible to execute. This\r | |
1339 | function must not change the state of any hardware devices, and this function must be aware that the\r | |
1340 | device specified by ControllerHandle may already be managed by the same driver or a\r | |
1341 | different driver. This function must match its calls to AllocatePages() with FreePages(),\r | |
1342 | AllocatePool() with FreePool(), and OpenProtocol() with CloseProtocol().\r | |
1343 | Since ControllerHandle may have been previously started by the same driver, if a protocol is\r | |
1344 | already in the opened state, then it must not be closed with CloseProtocol(). This is required\r | |
6879581d | 1345 | to guarantee the state of ControllerHandle is not modified by this function.\r |
