UMDF Certification

NTDEV
1

I have a driver pair, one KMDF and one UMDF that are both associated with an ACPI device. We have done WHCK testing in the past and have a signed CAT file from MSFT.

We have made changes to the UMDF driver, but not the KMDF driver. Do we have to do WHQL testing again, or since only the UMDF driver changed; is it not required?

This may boil down to an easier question, “Is WHCK testing required for a UMDF driver?”

Thanks…

If any binaries referenced by an INF file change, regardless of whether they are user or kernel mode, a new round of certification testing is in order. Sorry: I suspect that’s not the answer you were hoping for.

Thanks,

I believe if you change the code in the driver package (and if the UMDF and KDMF driver are in one package, installed by one INF, then you’ve done this) you will have to do the WHQL testing again.

Thanks. That is what I thought, but I was being told by others it was not required.
