WDF - Interrupt

Markus · April 20, 2006, 2:13pm

Hallo!

Currently I try to use an Interrupt (I just want to know if the interrupt
occurs) with WDF. But I’m not sure if the following steps ar enought:

Define BOOLEAN EvtDeviceInterruptIsr(IN WDFINTERRUPT Interrupt, IN ULONG
MessageID);
Register the Interrupt at “EvtDeviceAdd” with:

fdoData = FdoGetData(device);

WDF_INTERRUPT_CONFIG_INIT(&interruptConfig, EvtDeviceInterruptIsr, NULL);

WdfInterruptCreate(device, &interruptConfig, WDF_NO_OBJECT_ATTRIBUTES,
&fdoData->interrupt);

Is this all I must do?

You probably also want to set and implement EvtInterruptEnable and
EvtInterruptDisable so that you can program the hardware to actually
generate interrupts.

Additional question:

Is it possible to simulate an interrupt? (Tool, …)
It’s because the Hardware sends the interrupt very seldom so it’s hard to
test.

No there are not any supported methods. There have been articles
written on how to touch mother board specific registers to get an
interrupt to fire though and I am sure with sufficient pounding on the
io apic, you could get it to fire. Can you get a custom piece of
hardware that can trigger the interrupt more often? That might easier
and more cost effective in the end.
