Subject: Q:Shared IRQ
Date: Mon, 04 Mar 2002 17:48:16 -0600 [thread overview]
Message-ID: <3C8407C0.1000503@keyed-upsoftware.com> (raw)
I have written a driver for a pci board that uses interrupts. I install
the shared handler with a unique dev_id, or at least it should be unique
as it is the address of my driver's internal data struct for that card.
I get not only my interrupts, but also the interrupts of the shared
device, namely the network card. Is this what I should expect? If I
get a notification for the network card, why is the dev_id the same as
what I passed? If I didn't have an interrupt pending bit on my
hardware, how would I distinguish between the interrupts?
TIA
