[ofw] Loading Ibbus.sys

I am trying to load ibbus.sys for a physical hardware device, built privately. I am already in testmode to load our HCA host driver which has a test signature. But I understand that, since we don't install drivers from a single package, we cannot use the same test signature for ib stack.

Did you encounter any specific problem using IoRegisterPlugplaynotification  that made you to move to a new registration mechanism via IRP_MN_QUERY_INTERFACE (rdma verbs guid interface) ? 

Thanks very much
Sophia.

Are you trying to install ibbus.sys for a virtual device, or are you installing in response to a PnP enumeration of a physical HW device?

Are you loading a driver you built yourself?  If so, look at the WDK documentation about test signing drivers, including how to put the system into test mode so that test signed drivers will load.
