KmdfIrql2 rule (kmdf)

  • Article

The KmdfIrql2 rule specifies that a driver calls a framework method at an IRQL that is less than or equal to the maximum IRQL for that method.

This rule is similar to the KmdfIrql rule; however, the KmdfIrql rule is performed on callback functions which have IRQL requirements independent of their related object’s execution level specification.

Driver model: KMDF

How to test

At compile time

Run Static Driver Verifier and specify the KmdfIrql2 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.

For more information, see Using Static Driver Verifier to Find Defects in Drivers.
