Question on PNPD test for NDIS...

Chakradhar_Kommuri · January 7, 2011, 9:00am

Hello Gurus,
The MiniportFilterResourceRequirements states the following:
“NDIS can call MiniportFilterResourceRequirements several times before NDIS
calls the MiniportRemoveDevice function. But NDIS calls
MiniportFilterResourceRequirements only when a device is in the halted
state.”

But when I run the PNPD tests, I see MiniportFilterResourceRequirements
getting called while in other states as well. Am I missing anything?

Appreciate any insight.

Thanks,
Chakri

That is interesting. What state are you in? If you can, show us a snippet of your log file / debug spew that includes recent state changes, along with the call to MiniportFilterResourceRequirements.

I’m sure you know this information already, but I can’t resist showing off my favorite diagram on MSDN: http://msdn.microsoft.com/en-us/library/ff543701.aspx (which is also available in tabular form here: http://msdn.microsoft.com/en-us/library/ff560490.aspx ). Make sure that the “official” definition of Halted state matches up with your expectations.

Thanks for the reply Jeffrey. And sorry for the delay in reply; Friday
evening is not great time to post a query, after all.

My expectation is inline with the state diagram and state table, which is,
it should happen before MiniportInitializeEx happens. That would be after
AddDevice/MiniportHalt and before MiniportInitializeEx. Let me know if I
need to know more about this.

Below is the stack trace and my miniport state listing (some fields are
deliberately but harmlessly edited). This happens during resource PNPD
rebalance tests and my adapter is in running state. Please let me know if
you need more details.
