WdfInterruptLock rule (kmdf)

The WdfInterruptLock rule specifies that calls to the WdfInterruptAcquireLock method is used in strict alternation with calls to WdfInterruptReleaseLock. Moreover, at the end of any KMDF callback routine, the driver should not hold the framework spin lock object, obtained by a previous call to WdfInterruptAcquireLock.

How to test

At compile time

Run Static Driver Verifier and specify the WdfInterruptLock 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.
