Irql_Gather_DMA_Function rule (ndis)

The Irql_Gather_DMA_Function rule specifies that the NDIS scatter/gather DMA functions must be called at correct IRQL levels.

This rule verifies the following NDIS functions:

NdisMAllocateNetBufferSGList

NdisMAllocateSharedMemoryAsyncEx

NdisMDeregisterScatterGatherDma

NdisMFreeNetBufferSGList

NdisMRegisterScatterGatherDma

Driver modelNDIS

How to test

At compile time

Run Static Driver Verifier and specify the Irql_Gather_DMA_Function 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.

For more information, see Using Static Driver Verifier to Find Defects in Drivers.
