Hello all, ARTI (Adeos-based Real-Time Interface) is the experimental rewrite of the RTAI real-time interface for x86 over the Adeos nanokernel (http://www.freesoftware.fsf.org/adeos/). In other words, this is a replacement for the RTAI/x86 real-time interface module (aka "rtai.c") exclusively using the Adeos services to handle interrupts and exceptions. The API exported by ARTI is meant to be compatible with the original RTAI interface so that existing applications can use it seamlessly.
Basically, most of the internals have been rewritten in order to fully delegate the hardware interrupt control to Adeos. To this end, the new module creates an Adeos domain which has precedence over the Linux kernel into the interrupt pipeline. This way, each and every interrupt is first delivered to the ARTI module which further controls its propagation to Linux when needed. You can currently use ARTI in replacement of the original RTAI interface to run kernel-based applications over the standard UP scheduler. Neither the SMP scheduler nor LXRT are supported at this time. If interested, you can download this work from http://freesoftware.fsf.org/download/xenomai/misc/arti.tar.bz2 This code is in no way for production use. It is an experimental work aimed at fostering ideas and thoughts on both RTAI and Adeos development. More information can be found in the README file shipped with the distro. Regards, Philippe.
