[nvmewin] Windows Driver Community Release worked just once

[Robles, Raymond C]

Hi Nisha,

Thanks for reaching out to the OFA community. Before proceeding, could you please officially subscribe the nvmewin mailing list so that your emails do not need my specific approval? Here is a link on how to subscribe --> http://lists.openfabrics.org/mailman/listinfo/nvmewin

Once subscribed you can resend your email to the email distribution list. In the meantime, please setup a WinDbg debug session for the OFA Windows driver and walk the source code for the create I/O completion queue command. Why did it fail (i.e. SCT and SC values)? 

If your PCIe device is in a bad state, then FindAdapter will not be called. The OFA driver has gone through rigorous testing and works with all known release NVMe devices. Of course, there are always new use cases that could potentially expose bugs. But I would first ensure that your particular failure is not specific to you H/W. Which NVMe device are you using?

Thank you...
Ray

Subject: [nvmewin] Windows Driver Community Release worked just once

Hi,

I have a PCIe NVME card under development that works on Linux. I want to use this card on Win 7 64bit.

I downloaded the NVMe Windows Driver Community Release source code, built and installed it. The very first time the driver loaded, it was able to detect my NVME board and send admin commands. However it Asserted while creating I/O completion queue. After that it has stopped working under Windows (but continues to work under Linux).

I see that when driver loads, DriverEntry() returns 0, but NVMeFindAdapter does not get called. What can I do to fix this issue?

TIA
Nisha Miller
