Hi all,
I am using irq_desc array in my program to list out
the names of all devices those who registered their
interrupt handler. while loading the module i am
getting "unresolved symbol irq_desc" as an error. i am
using 2.4.24 kernel and this is my code. Can anybody
plz explain me whats the problem.
Deepak,
irq_desc is not EXPORTED symbol ..... so you can not use that in your
module. While loading a module insmod trying to link the unresolved
symbols with only EXPORTED symbols of running kernel. If any of the
symbols used in module is not actually exported by kernel, then insmod
fails to link your module and gives this error.
For loading your module, you need to export irq_desc symbol
explicitely using EXPORT_SYMBOL() macro in your kernel sources, build
the new kernel image and boot your machine from that kernel image,
then try to load your module, it should be loaded properly.

Gaurav
