SpinlockRelease rule (kmdf)

  • Article

The SpinlockRelease rule specifies that calls to KeAcquireSpinLock, KeAcquireSpinLockRaiseToDpc, and KeReleaseSpinLock are used in a balanced way within a KMDF callback. At the end of any KMDF callback routine, the driver should not hold the spin lock.

Driver model: KMDF

How to test

At compile time

Run Static Driver Verifier and specify the SpinlockRelease 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.
