Interrupt handling adds another layer of complexity. If the PCI controller can signal interrupts (e.g., when data arrives or a transaction completes), the driver must register an Interrupt Service Routine (ISR) using WdfInterruptCreate . The ISR runs at high IRQL (DIRQL), and its job is only to acknowledge the interrupt at the device level and defer any heavy processing to a EvtInterruptDpc (Deferred Procedure Call). Within the DPC routine, the driver can read from the device buffers, copy data to a queue, and signal any waiting user applications via events. In a simple driver, one might avoid interrupts altogether by using polling, but this wastes CPU cycles and is unsuitable for low-latency or high-throughput applications.
