Hello everyone,
I am writing a RTLinux device driver for a CPCI Waveform digitizer and am
running into some major problems with IRQ conflicts on my system.
My application is time critical so I would like to be able to use
RTLinux's hard IRQ capabilities. However, since I have a large number of
modules (six) on the CPCI bus there seems to always be a conflict between
one of my modules and an IRQ line used by a Linux (non-RT) device. This
creates a problem because my driver cannot service the Linux device's
interrupt and RTLinux won't release the interrupt since my driver has
registered a hard IRQ.
The optimal sollution would to re-assign the IRQ lines so that there is no
conflict. Unfortunately though the BIOS my system is using (AWARD) does
not support this nor do I know of a way to do it in Linux.
Any suggestions would be greatly appreciated.
cheers,
-Dan
