Port/miniport interface checking

  • Artikel

Port/miniport interface checking enables Driver Verifier to inspect the DDI interface between PortCls.sys and its audio miniport drivers, along with ks.sys and its AVStream miniport drivers. See Rules for AVStream drivers and Rules for audio drivers

Activating this option:

You can activate port/miniport interface checking for one or more drivers by using Driver Verifier Manager or the Verifier.exe command line. For details, see Selecting driver verifier options. You must restart the computer to activate or deactivate the port/miniport interface checking option.

    The feature will be active after the next boot.
