MiniportOnlyWdmDevice rule (kmdf)

  • Article

The MiniportOnlyWdmDevice rule specifies that WDF drivers should not use IoCreateDevice and IoCreateDeviceSecure functions to create bare WDM device objects. This will cause the computer to crash if someone tries to send an IRP to the WDM device. This is because IRP dispatch entries of the device are set to WDF-specific entries, but the framework hasn’t created a WDF device. However, miniport drivers can use the DDIs because driver dispatch entry points aren’t set for them.

Driver model: KMDF

How to test

At compile time

Run Static Driver Verifier and specify the MiniportOnlyWdmDevice rule.

Use the following steps to run an analysis of your code:
  1. Prepare your code (use role type declarations).
  2. Run Static Driver Verifier.
  3. View and analyze the results.
