How can I see what IRQ's are in use?

I do not know if it is possible on QNX, but is there a way to see what IRQ’s are in use?

pidin ir. But that software usage and not hardware usage. What I mean is that it will tell you which IRQ have software attached to them. It doesn’t tell you what hardware is connected to what IRQ.

I am using 6.2.0, and do not have option ‘ir’ for pidin.

Then you are out of luck.

if you type pci you can see which irq is used for pci.
