IrqlDispatch rule (storport)

  • Article

This rule verifies that the following routines are only called at IRQL = DISPATCH_LEVEL.

  • AllocateAdapterChannel

  • FreeAdapterChannel

  • FreeMapRegisters

  • GetScatterGatherList

  • IoAllocateController

  • IoFreeController

  • IoStartNextPacket

  • KeAcquireSpinLockAtDpcLevel

  • KeInsertByKeyDeviceQueue

  • KeInsertDeviceQueue

  • KeReleaseSpinLockFromDpcLevel

  • KeRemoveByKeyDeviceQueue

  • KeRemoveDeviceQueue

  • PutScatterGatherList

Driver model: Storport

How to test

At compile time

Run Static Driver Verifier and specify the IrqlDispatch 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.
