Getting a list of used irqs?

I need to see what IRQs the system is currently using. How do I do this? (sin interrupt does not
reveal anything…)

Also; has anyone used the parallel post’s ACK-pin for asserting interrupts? We are having trouble
getting it to work. This is why I need to check if there is an interrupt collision or not.

We finally got the parallel IRQ working!
However still no listing of attached IRQ-handlers… it would be nice to be able too get this info
from the OS, in the order they were attached…

You can use pci -v to get PCI irq’s and info.

I agree, I miss “sin irq” as well…
