Has anyone here used ART-Linux yet? It's a real time Linux version from Japan and what intrigued me was the claim of 10us latency on a Pentium II. If I remember correctly Molnar's RT-Linux patches can't even manage that on current hardware. They even have kernels for Ubuntu 8.04 (but unfortunately not 8.10). http://art-linux.sourceforge.net/ http://www.linuxdevices.com/news/NS5878102799.html ...

http://rt.wiki.kernel.org/index.php/RT_PREEMPT_HOWTO Hi, Although Real Time Linux isn't necessarily new, most solutions use a RTOS kernel which runs the Linux kernel as a low-priority thread and having some intercommunications between it and Linux.

Hi, Let's say I'm developing a control system for a UAV and I've decided to use Linux with RTAI in the vehicle. I have a real-time task which does the actual actuation of the flight surfaces and it controls the hardware (motors) through GPIO pins. The RT task is talking to Linux through a fifo (which Linux processes see as a block device) and Linux has a device driver for a wireless ...
