Synchronizing with an MSI Interrupt

Synchronizing with an MSI Interrupt

If a miniport driver's MiniportMessageInterrupt function shares resources, such as network interface card (NIC) registers or state variables, with another MiniportXxx function that runs at a lower IRQL, the other MiniportXxx function must call the NdisMSynchronizeWithInterruptEx function. This call ensures that the miniport driver's MiniportSynchronizeMessageInterrupt function accesses the shared resources in a synchronized and multiprocessor-safe manner.
