[ofw] Loading Ibbus.sys

[James Yang]

You can treat ibbus as your driver and put the test signature on it.

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.
