Greetings!

I have a question regarding applications running on embedded Linux on
an ML310. Getting things to work under standalone has been fairly easy
with my custom hardware (just a little pulse counter generating
interrupts on each pulse, in Verilog). I want to make a jump to
running this same application (that really just handles the interrupts
and reads the register that holds the counter value) to MontaVista
Linux on one of the PPCs in the V2Pro. The thing is that the BSP is
pretty different for Linux as the OS than standalone, so all the
header files are in different places or not even there.

I've been instructed to cross-compile the application on the host
machine (which I know I can do), but do I have to know how to handle
interrupts under Linux (like, by reading O'Reilly's Linux Device
Drivers) to be able to run this application properly? For example,
xexception_l.h wasn't copied to my project directory, which I needed
for standalone, but I don't know what to replace it with for interrupt
handling under Linux. It seems like doing things for embedded Linux is
a completely different monster. And I'm pretty clueless when it comes
to the inner workings of Linux. Thanks a ton!
