SpinLockSafe rule (storport)

  • Makale

This rule verifies that the IoStartNextPacket and IoCompleteRequest routines are not called while holding a spin lock. The rule keeps track of the number of spin locks held at any time, and if that number is not 0 when either routine is called, the driver fails the rule.

Driver model: Storport

How to test

At compile time

Run Static Driver Verifier and specify the SpinLockSafe 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.
