90 | Tests to see if this driver supports a given controller. If a child device is provided, | |
91 | it further tests to see if this driver supports creating a handle for the specified child device. | |
92 | ||
93 | This function checks to see if the driver specified by This supports the device specified by | |
94 | ControllerHandle. Drivers will typically use the device path attached to | |
95 | ControllerHandle and/or the services from the bus I/O abstraction attached to | |
96 | ControllerHandle to determine if the driver supports ControllerHandle. This function | |
97 | may be called many times during platform initialization. In order to reduce boot times, the tests | |
98 | performed by this function must be very small, and take as little time as possible to execute. This | |
99 | function must not change the state of any hardware devices, and this function must be aware that the | |
100 | device specified by ControllerHandle may already be managed by the same driver or a | |
101 | different driver. This function must match its calls to AllocatePages() with FreePages(), | |
102 | AllocatePool() with FreePool(), and OpenProtocol() with CloseProtocol(). | |
103 | Because ControllerHandle may have been previously started by the same driver, if a protocol is | |
104 | already in the opened state, then it must not be closed with CloseProtocol(). This is required | |
105 | to guarantee the state of ControllerHandle is not modified by this function. | |

108 | @param[in] ControllerHandle The handle of the controller to test. This handle | |

112 | parameter is ignored by device drivers, and is optional for bus | |
113 | drivers. For bus drivers, if this parameter is not NULL, then | |
114 | the bus driver must determine if the bus controller specified | |
115 | by ControllerHandle and the child controller specified | |
116 | by RemainingDevicePath are both supported by this | |
