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.

|
|
parameter is ignored by device drivers, and is optional for bus

the bus driver must determine if the bus controller specified

by ControllerHandle and the child controller specified

by RemainingDevicePath are both supported by this

bus driver.
