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.

/**

|
Stops a device controller or a bus controller.
|
|
|
|
The Stop() function is designed to be invoked from the EFI boot service DisconnectController().
|
|
As a result, much of the error checking on the parameters to Stop() has been moved
|
|
into this common boot service. It is legal to call Stop() from other locations,
|
|
but the following calling restrictions must be followed, or the system behavior will not be deterministic.
|
|
1. ControllerHandle must be a valid EFI_HANDLE that was used on a previous call to this
|
|
same driver's Start() function.
|
|
2. The first NumberOfChildren handles of ChildHandleBuffer must all be a valid
|
|
EFI_HANDLE. In addition, all of these handles must have been created in this driver's
|
|
Start() function, and the Start() function must have called OpenProtocol() on
|
|
ControllerHandle with an Attribute of EFI_OPEN_PROTOCOL_BY_CHILD_CONTROLLER.
|
|
|
|
@param[in] This A pointer to the EFI_DRIVER_BINDING_PROTOCOL instance.
|
|
@param[in] ControllerHandle A handle to the device being stopped. The handle must
|
|
support a bus specific I/O protocol for the driver
|
|
to use to stop the device.
|
|
@param[in] NumberOfChildren The number of child device handles in ChildHandleBuffer.
|
|
@param[in] ChildHandleBuffer An array of child handles to be freed. May be NULL
|
|
if NumberOfChildren is 0.
|
|
|
|
@retval EFI_SUCCESS The device was stopped.
|
|
@retval EFI_DEVICE_ERROR The device could not be stopped due to a device error.
