IrqlDispatch rule (storport)

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: Prepare your code (use role type declarations). Run Static Driver Verifier. View and analyze the results. For more information, see Using Static Driver Verifier to Find Defects in Drivers.
