Irql_Gather_DMA_Function rule (ndis)

  • Article

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 model: NDIS

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.
