I strongly believe in "as simple as possible, but no simpler"...

To coin a phrase... give a newbie some code, they'll be able to code for the exercise, give them some direction, they'll be able to code for life...

comment Is there a good way to poll in a real-time process which is kernel friendly?
Thanks for your input, yes, I understand that run() will block, however the downside of this is that I'm now waiting on an interrupt to pick up the next packet. The poll() approach means I don't need to wait for this - the downside being I'm blocking other kernel level stuff running, it seems evident that an upgrade to the latest kernel is the only way forward...

comment Negatives of running processes with real-time priority?
Yes - this is the main problem that I appear to encounter. Short of reading through the kernel code to determine all the processes that need to have a higher priority, the only option is to starve all others aside from my process and then move anything that requires any form of io to other cores... hmmm...

@ire_and_curses, currently the process runs on it's own isolated core (at least the main processing thread), however the interrupts aren't scheduled on that same core (can't do this as there are several similar processes relying on the same network interface), this is more of a last effort.The APIC frequency is interesting, I've not encountered this before.

I wanted to see if I could get away without writing something for it! :) I guess this will do the trick! Thanks!
