Shared Interrupt programming query

Hello hackers,

I'm a novice device-driver programmer and have some questions about
the shared-interrupt implementation in Linux. My understanding is that the
kernel provides functionality for device drivers to operate on devices
which are sharing an IRQ, but it is the responsibility of the device-driver
itself to determine whether the interrupt is for it's respective device.
This would assume that the device itself provides some mechanism for
verifying it did indeed interrupt. Is this a correct understanding?

thanks,
-bp
