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

it further tests to see if this driver supports creating a handle for the specified child device.
|
|
|
|
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
|
|
to guarantee the state of ControllerHandle is not modified by this function.
