Folks, We are building a robot, and have been advised to use QNX (www.qnx.com) for that. QNX is a real-time OS that claims POSIX compliance. All nice and well, but I want APT and my familiar Linux environment. I know that there are realtime patches for Linux floating around. So I am wondering if any of you have had experience with any of those patches. Are they reliable and usable, and do they allow my controllers to run in real-time while I can still maintain the box with my Debian knowledge? Lastly: does anyone have a good document covering realtime, what it's needs are, and what it does? I know that realtime means that processes don't get put in a queue but run immediately. How that works with a multi-tasking OS is a bit foggy to me. Moreover, what's the difference between a process on a realtime OS, and one with nice -20?
