Correct way of reporting broken device

NTDEV
1

Hello

Assuming a functional device driver can determine that the hardware is broken - what is the correct way of reporting it to the OS?

Ideally, I would like to be able to report it in such a way that the device is removed from the system and that no future I/O-requests are forwarded to the driver.

Thanks in advance!

Regards
Johan

IoInvalidateDeviceState followed by responding with PNP_DEVICE_FAILED
to the subsequent IRP_MN_QUERY_PNP_DEVICE_STATE request. This should
result in an IRP_MN_SURPRISE_REMOVE showing up.
