如何让IO管理器在我的驱动程序中调用我的AddDevice例程？ [英] How to make IO Manager call my AddDevice routine in my driver?

问题描述

大家好！

我是司机开发的新人。我写了一个通过文件实现虚拟磁盘的驱动器。 DriverEntry例程如下：

 NTSTATUS DriverEntry（PDRIVER_OBJECT drvObject，PUNICODE_STRING usRegPath）
 {
 PKEY_VALUE_PARTIAL_INFORMATION startKeyValue; 
 ULONG版; 
  int  i; 
 
转储（  DriverEntry DRIVER_NAME   DRIVER_VERSION   \ N）; 
 
 memset（& OsVersion， 0 ， sizeof （RTL_OSVERSIONINFOW））; 
 OsVersion.dwOSVersionInfoSize =  sizeof （RTL_OSVERSIONINFOW）; 
 RtlGetVersion（& OsVersion）; 
  //  转储（RtlGetVersion：％d，％d \\\\ n，OsVersion。 dwMajorVersion，OsVersion.dwMinorVersion）;  
  //  如果主驱动程序已经加载转储过滤器已加载 
 如果（NT_SUCCESS（FDDeviceIoControl（NT_ROOT_PREFIX，FD_IOCTL_GET_DRIVER_VERSION，NULL， 0  ，& version， sizeof （版本））））
  return  DumpFilterEntry（（PFILTER_EXTENSION） drvObject，（PFILTER_INITIALIZATION_DATA）usRegPath）; 
 
 FDDriverObject = drvObject; 
 memset（VirtualVolumeDeviceObjects， 0 ， sizeof （VirtualVolumeDeviceObjects））; 
 
  if （NT_SUCCESS（FDReadRegistryKey（usRegPath，L  开始，& startKeyValue）））
 {
  if （startKeyValue-> Type = = REG_DWORD&& *（（uint32 *）startKeyValue-> Data）== SERVICE_BOOT_START）
 {
 LoadBootArguments（）; 
} 
 FDfree（startKeyValue）; 
} 
  else  
 {
转储（ 读取注册表项值失败！\ n）; 
} 
 
 VolumeClassFilterRegistered = IsVolumeClassFilterRegistered（）; 
 ReportBOOL（  VolumeClassFilterRegistered，VolumeClassFilterRegistered）; 
 
  for （i =  0 ; i< = IRP_MJ_MAXIMUM_FUNCTION; ++ i）
 {
 FDDriverObject-> MajorFunction [i] = FDDispatchQueueIRP; 
} 
 FDDriverObject-> DriverExtension-> AddDevice = FileDiskAddDevice; 
 
 drvObject-> DriverUnload = UnloadDriver; 
 
  return  FDCreateRootDeviceObject（FDDriverObject）; 
} 

在上面的代码中，我注册了一个名为FileDiskAddDevice的AddDevice例程。通过DebugPrint输出的消息，我看我的驱动程序可以被系统成功加载。接下来，我想让IO管理器调用我的AddDevice例程。但我不知道该怎么做。我的驱动程序仅用于虚拟设备。没有真正的设备适合它。所以我不能通过拔下插头再添加设备。我希望有人能够善意地告诉我应该做些什么。谢谢！微笑| :)

Hi all!
I am a new guy for driver development. I had written a drive to implement a virtual disk through file. The DriverEntry routine is as below:

NTSTATUS DriverEntry(PDRIVER_OBJECT drvObject, PUNICODE_STRING usRegPath)
{
	PKEY_VALUE_PARTIAL_INFORMATION startKeyValue;
	ULONG version;
	int i;
 
	Dump("DriverEntry " DRIVER_NAME " " DRIVER_VERSION "\n");
 
	memset(&OsVersion, 0, sizeof(RTL_OSVERSIONINFOW));
	OsVersion.dwOSVersionInfoSize = sizeof(RTL_OSVERSIONINFOW);
	RtlGetVersion(&OsVersion);
	//Dump("RtlGetVersion:%d,%d\r\n", OsVersion.dwMajorVersion, OsVersion.dwMinorVersion);
	// Load dump filter if the main driver is already loaded
	if (NT_SUCCESS (FDDeviceIoControl (NT_ROOT_PREFIX, FD_IOCTL_GET_DRIVER_VERSION, NULL, 0, &version, sizeof (version))))
		return DumpFilterEntry ((PFILTER_EXTENSION) drvObject, (PFILTER_INITIALIZATION_DATA) usRegPath);
 
	FDDriverObject = drvObject;
	memset(VirtualVolumeDeviceObjects, 0, sizeof(VirtualVolumeDeviceObjects));
 
	if(NT_SUCCESS(FDReadRegistryKey(usRegPath, L"Start", &startKeyValue)))
	{
		if(startKeyValue->Type == REG_DWORD && *((uint32 *)startKeyValue->Data) == SERVICE_BOOT_START)
		{
			LoadBootArguments();
		}
		FDfree(startKeyValue);
	}
	else
	{
		Dump("Read registry key value failure!\n");
	}
 
	VolumeClassFilterRegistered = IsVolumeClassFilterRegistered();
	ReportBOOL("VolumeClassFilterRegistered", VolumeClassFilterRegistered);
 
	for (i = 0; i <= IRP_MJ_MAXIMUM_FUNCTION; ++i)
	{
		FDDriverObject->MajorFunction[i] = FDDispatchQueueIRP;
	}
	FDDriverObject->DriverExtension->AddDevice = FileDiskAddDevice;
 
	drvObject->DriverUnload = UnloadDriver;
 
	return FDCreateRootDeviceObject(FDDriverObject);
}

In the code above, I had register a AddDevice routine named FileDiskAddDevice. Through the message output by DebugPrint, I look my driver can be loaded successfully by system. Next, I want to make IO manager call my AddDevice routine. But I don't know how to do it. My driver is just for a virtual device. No real device fits it. So I can't add device by unplug and plug again. I hope someone can be kind to tell me what I should do. Thank you! Smile | :)

Be regards!
