现在我想添加我的acpi驱动程序中的function。 function是：获取BIOS通知。 我search一些文档，并编写代码
NTSTATUS XxxAddDevice( __in struct _DRIVER_OBJECT *DriverObject, __in struct _DEVICE_OBJECT *PhysicalDeviceObject ) { . . . status = STATUS_SUCCESS; DebugPrint(("AddDevice: %p to %p->%p \n",fdo,fdoData->NextLowerDO,PhysicalDeviceObject)); DebugPrint(("DeviceObject Flag = 0x%08x\n",fdo->Flags)); DebugPrint(("DevicePnPState = %d\n", fdoData->DevicePnPState)); { //PACPI_INTERFACE_STANDARD2 pInterface = // ExAllocatePool(PagedPool, sizeof(ACPI_INTERFACE_STANDARD2)); ACPI_INTERFACE_STANDARD Interfaces = {0}; if (&Interfaces == NULL) { goto FuncEnd; } //RtlFillMemory(pInterface, sizeof(ACPI_INTERFACE_STANDARD2), 0x00); status = GetAcpiInterfaces(fdo, &Interfaces); if (!NT_SUCCESS(status)) { DebugPrint(("GetAcpiInterfaces Failed\n")); } else { DebugPrint(("******GetAcpiInterfaces Succeed\n")); DebugPrint(("******ACPI_INTERFACE_STANDARD2 Version == %d\n", Interfaces.Version)); DebugPrint(("******AcpiInterface.RegisterForDeviceNotifications Address == %x\n", Interfaces.RegisterForDeviceNotifications)); //Interfaces.InterfaceReference(Interfaces.Context); } if (Interfaces.RegisterForDeviceNotifications != NULL) { status = Interfaces.RegisterForDeviceNotifications( Interfaces.Context, ACPIDeviceNotifyHandler, fdoData); if (!NT_SUCCESS(status)) { DebugPrint(("RegisterForDeviceNotifications Failed\n")); } else { DebugPrint(("RegisterForDeviceNotifications Succeed\n")); } } //Free Memory //ExFreePool(pInterface); // PDEVICE_OBJECT target = fdoData->NextLowerDO; // RegisterACPINotifyEvent(target, fdoData); status = STATUS_SUCCESS; } FuncEnd: return status; } NTSTATUS GetAcpiInterfaces( IN PDEVICE_OBJECT Pdo, OUT PACPI_INTERFACE_STANDARD AcpiInterfaces ) { NTSTATUS Status = STATUS_NOT_SUPPORTED; PIRP Irp; PIO_STACK_LOCATION IrpSp; PDEVICE_OBJECT LowerPdo = NULL; KEVENT event; DebugPrint(("Enter GetAcpiInterfaces...\n")); KeInitializeEvent(&event, NotificationEvent, FALSE); // Only need to do this once if (!LowerPdo) { LowerPdo = IoGetAttachedDeviceReference(Pdo); // Allocate an IRP for below Irp = IoAllocateIrp // (LowerPdo->StackSize, FALSE); // Get stack size from // PDO Irp = IoAllocateIrp(LowerPdo->StackSize, FALSE); if (Irp == NULL) { DebugPrint(("IoAllocateIrp Failed...\n")); Status = STATUS_UNSUCCESSFUL; return Status; } IrpSp = IoGetNextIrpStackLocation(Irp); // // Use QUERY_INTERFACE to get the address of the direct- // call ACPI interfaces. // IrpSp->MajorFunction = IRP_MJ_PNP; IrpSp->MinorFunction = IRP_MN_QUERY_INTERFACE; IrpSp->Parameters.QueryInterface.InterfaceType = (LPGUID)&GUID_ACPI_INTERFACE_STANDARD; IrpSp->Parameters.QueryInterface.Version = 1; IrpSp->Parameters.QueryInterface.Size = sizeof(ACPI_INTERFACE_STANDARD); IrpSp->Parameters.QueryInterface.Interface = (PINTERFACE)AcpiInterfaces; IrpSp->Parameters.QueryInterface.InterfaceSpecificData = NULL; IoSetCompletionRoutine(Irp, ACPIDriverSynchronousRequest, &event, TRUE, TRUE, TRUE); DebugPrint(("******Before IoCallDriver.Status == %08X\n", Status)); Status = IoCallDriver(LowerPdo, Irp); DebugPrint(("******IoCallDriver.Status == %08X\n",Status)); //Wait for complete if (Status == STATUS_PENDING) { DebugPrint(("KeWaitForSingleObject QueryInterface...\n")); Status = KeWaitForSingleObject(&event, Executive, KernelMode, FALSE, NULL); DebugPrint(("KeWaitForSingleObject.Status == %08X\n", Status)); DebugPrint(("pNewIrp->IoStatus.Status == %08X\n", Irp->IoStatus.Status)); } //IoFreeIrp(Irp); } return Status; } CompletionRoutine返回STATUS_SUCCESS，但接口仍为空…
Parameters.QueryInterface.Interface不会被填充…有人能帮我吗？ MSDN关于IRP_MN_QUERY_INTERFACE 在这里 input 链接描述在这里 input图像描述
好的，现在我自己回答我的问题。 驱动程序必须安装在\ Driver \ Acpi上，它将工作。 所以请使用dpinst.exe和参数“/ f”
