Re: Adding a new interrupt handler to the IDT

Doh! I should have mentioned that I'm running the 2.6.16 kernel on an IA32 platform.

I have a system which will be creating CPU interrupts via a user-supplied IDT value. I have a kernel module which will handle the interrupt - I just need to hook this code into the interrupt handler mechanism. I cannot find any documentation on how to create an entry in the IDT or to identify the linkage protocol (assuming I can create an IDT entry).

Note: These are NOT IRQs and, therefore, the request_irq() services cannot be used. This would be equivalent to creating a handler for the INT instruction.

Any ideas or pointers would be appreciated.

Thanks - Martin
