Yes, I'm aware. Thanks. I simply wanted to mention that the same source code
can be compiled and loaded in a uniprocessor successfully. I also understand
that I will have to make some code changes (spinlocks, etc.) to make it run
correctly in smp.
Maybe I'm missing something in the way I'm building my module for smp.
To build it for smp I copied my source code to a system running Linux SMP and
added -D__SMP__ to my CFLAGS in the Makefile. Then I simply used make to build
it. The process builds the module without problems, but insmod complains about
unresolved symbols. What am I missing?
I got the source for the smp kernel from the appropriate rpm. Is there something
special that I need to do in order to "build the module against a matching SMP
kernel configuration" ?
Thanks again,
Juan
