IopInitializeDeviceInstanceKey调用IoCreateDevice后调用IopMapDeviceObjectToDeviceInstance添加到nt!PpDeviceReferenceTable

BOOLEAN
IopInitializeDeviceInstanceKey(
IN HANDLE KeyHandle,
IN PUNICODE_STRING KeyName,
IN OUT PVOID Context
)
{

//
// Create madeup PDO and device node to represent the root device.
//

status = IoCreateDevice( IoPnpDriverObject,
sizeof(IOPNP_DEVICE_EXTENSION),
NULL,
FILE_DEVICE_CONTROLLER,
FILE_AUTOGENERATED_DEVICE_NAME,
FALSE,
&deviceObject );

if (NT_SUCCESS(status)) {

deviceObject->Flags |= DO_BUS_ENUMERATED_DEVICE;
deviceObject->DeviceObjectExtension->ExtensionFlags |= DOE_START_PENDING;

status = PipAllocateDeviceNode(deviceObject, &deviceNode);
if (status != STATUS_SYSTEM_HIVE_TOO_LARGE && deviceNode) {

。。。。。。

//
// Add an entry into the table to set up a mapping between the DO
// and the instance path.
//

status = IopMapDeviceObjectToDeviceInstance(deviceNode->PhysicalDeviceObject, &deviceNode->InstancePath);
ASSERT(NT_SUCCESS(status));
