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

This function checks to see if the driver specified by This supports the device specified by

ControllerHandle. Drivers will typically use the device path attached to
|

ControllerHandle and/or the services from the bus I/O abstraction attached to
|

ControllerHandle to determine if the driver supports ControllerHandle. This function

may be called many times during platform initialization. In order to reduce boot times, the tests

performed by this function must be very small, and take as little time as possible to execute. This
|
||||
function must not change the state of any hardware devices, and this function must be aware that the

device specified by ControllerHandle may already be managed by the same driver or a

different driver. This function must match its calls to AllocatePages() with FreePages(),

AllocatePool() with FreePool(), and OpenProtocol() with CloseProtocol().
|

Because ControllerHandle may have been previously started by the same driver, if a protocol is

already in the opened state, then it must not be closed with CloseProtocol(). This is required
