StorPortStartIo rule (storport)

Waits or data allocation must never be performed in the miniport's StartIo routine. The driver fails the rule if it calls StorPortStallExecution or another function that involves time-consuming operations. Since StartIo is synchronized, these calls should mostly be done in BuildIo.

How to test

At compile time

Run Static Driver Verifier and specify the StorPortStartIo 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.
