KMDF Smart Card Reader Windows Universal Driver ApiValidator Error

NTDEV

ApiValidator constantly reports error while porting our WDF KMDF smart card reader driver to window 10 universal driver. The error log is given below

ApiValidation: Warning: API _allmul in ntoskrnl.exe is not a supported universal API. Samplex86.sys calls this API.

Development Environment used is Visual Studio 2015 WDK 1703 (10.0.15063.0)
Did anyone face the same issue with ntoskrnl.exe or smclib.sys ?
How to make smart card drivers to be universal drivers ?

The ntos errors are strange, they should not be reported. The smclib errors are expected, smclib isn’t a universal library. How are you invoking apivalidator?

Dear Dorn,
Thank you for the response. I used ApiValidator from command line.
If -SupportedApiXmlFiles: is set to x64\UniversalDDIs.xml then NTOS errors are reported.
If -SupportedApiXmlFiles: is set to x86\UniversalDDIs.xml then ONLY smclib is reported.

I am currently using Visual Studio 2015 WDK 1703 (10.0.15063.0).

Best Regards
Xavier

The universal apis xml file needs to match the bitness of the file being checked, so the x86 xml must only be used against Samplex86.sys. That leaves the smclib errors which are expected no matter the architecture
