I want to trigger hardware interrupts as described in the book Linux Device Drivers by connecting pins 9 and 10 with a wire. I tried that but apparently there's no interrupt beeing triggered:
cat /proc/interrupts
:
7: 0 XT-PIC parport0
Now I wonder why's that? Kernel modules are loaded:
parport_pc 26004 0
parport 35239 2 ppdev,parport_pc
In the book it says interrupts have to be enabled, but that's the case when the module is loaded, right?
Any ideas what I could do?
