My hardware is a PCIExpress card.
I have an Interrupt Spin Lock in use (WdfInterruptAcquireLock()), to sync fifo operations against the ISR.
Now on DeviceManager “Deactivate” the customer gets (sometimes) a Dead Lock, see below.
I assume that the Interrupt Spin Lock is acquired by an asynchronical DPC or WorkerItem, while KMDF/PnP disables the corresponding Interrupt.
Unfortunately I can only debug by kernel dump produced on a remote customer machine.
I’m out of ideas, so some questions:
How to sync WdfInterruptDisable with use of an interruptLevelLock … is it automatically?
What todo in
EvtDeviceD0Exit
EvtDeviceD0ExitPreInterruptsDisabled
EvtInterruptDisable
?
thanks for caring,
Joerg Hoppe
