Hello all,
I would like to write a program that monitors various system
parameters in real time. One of these is counting the number of
interrupts. I would like to implement my own interrupt handler so that
each handler counts the number of interrupt of its respective type.
I have read various guides and tutorials but none of them have
discussed this matter.
The module is intended to be installed on an Intel architecture machine.
Any tips or source code would be graciously accepted.
Regards,
Zvi

ehm
the kernel already keeps this kind of data, see /proc/interrupts
why would you want to collect it *again* ?
(or do you want to generally hook interrupts like some other people want
to hook syscalls?)

You have a good point point - I should have given a better decription
to my problem.
This is an educational project I'm working on and I need to actually
see the contents of the Interrupt Descritor Table so I could load it
into user space and have it displayed in a nice GUI.
