IRQ Sharing

From: Jorge Almeida

Hello to all.

I'm running an application that uses several IO boards in a PCI bus.

My main problem is the virtual IRQ sharing between several boards.
I mean for example:
1 ethernet board IRQ = 169;
1 ADC card IRQ = 169;

I want to get ride of this behaviour, and changing the slot position of each
board is not enought, to get something like (for example):
1 ethernet board IRQ = 169;
1 ADC card IRQ = 170;

Where in the kernel i can see the algorithms for the APIC system where the
virtual IRQs are distributed? Or exist already any patch that permits to
solve my problem?

I'm using kernel 2.6.16.27, in a single machine with Intel pentium IV
processor and chipset ICH4.

Thanks for any reply.
Greetings.
