| I'm running Linux 2.4.18-rmk7 on a system based on ARM EP7312.
I am attempting to write a driver that will use FIQ, but when I insmod that
module calls like claim_fiq, set_fiq_handler, and others described in fiq.c
that should be resolved, are not.
My first question is: what config options should I change to make sure that
FIQ support gets linked into my kernel.
While that is unresolved I decided to go ahead and brute-force my way
through this problem. I am trying to manually re-initialize the FIQHandler
vector (0x1C) to my handler, but I am not able to do that. I tried ioremap
on the vector-table region, etc. Could someone please suggest a way to do
that?
Any sample code or at least a knowledge base where this issue is discussed
are welcome
Thanks.
