hey，i'm trying to modify KMDOD sample but get some trouble on it.Before DxgkInitializeDisplayOnlyDriver ,i found DxgkDispatchIoRequest,in my opinion, this should be used for IOCTL,so I created the control device and symbolic link in AddDevice,and also registered IRP_MJ_CREATE,IRP_MJ_CLOSE,IRP_MJ_CLEANUP in DriverEntry.But when I use CreateFile to open the symbolic link, it returns error code 1.
I think I can be sure that my code for creating control devices and symbolic links is completely correct (I have some related codes under WDF, but this is my first time to change the code of WDDM).
So, what might cause this error 1 (except for not registering IRP_MJ_CREATE in DriverEntry).
