IrqlKeRaiseLower rule (wdm)
The IrqlKeRaiseLower rule specifies that the driver does the following when raising and lowering the IRQL:
When the driver calls KeRaiseIrql, it is executing at an IRQL that is lower than or equal to the value of the NewIrql parameter. The driver calls KeLowerIrql only after calling KeRaiseIrql or KeRaiseIrqlToDpcLevel. This rule permits nested calls to KeRaiseIrql, KeRaiseIrqlToDpcLevel, and KeLowerIrql.
How to test
|At compile time|
Run Static Driver Verifier and specify the IrqlKeRaiseLower rule.Use the following steps to run an analysis of your code:
