Requests That KMDF Does Not Support

Last Updated: 7/30/2016

[Applies to KMDF only]

Kernel-Mode Driver Framework (KMDF) does not support I/O requests that have the following major IRP codes:

When the framework receives such a request, its default action depends on the device object that was the target of the request. For an FDO or PDO, the framework completes the IRP with the status STATUS_INVALID_DEVICE_REQUEST. For a filter DO, the framework passes the IRP to the next lower driver. Although the framework does not support these request types, a KMDF driver can still handle them. For more information, see Handling an IRP that the Framework Does Not Support.
