Xenomai is a Free Software project in which engineers from a wide background collaborate to build a robust and resource-efficient real-time core for Linux© following the dual kernel approach, for applications with stringent latency requirements.
-
The current stable release is Xenomai 3.2.1.
We are also paving the way to Xenomai 4, which is going to be based on the next generation real-time core developed by the EVL project, with the intent to preserve the user investment in Xenomai 3.x. To this end, the specification process of a Common Xenomai Platform has started. By this process, we define a set of common features and interfaces future Xenomai releases will share, starting from Xenomai 3.3.

Interrupt pipeline (Dovetail, I-pipe)
The Cobalt real-time core depends on patches to the mainline Linux kernel, which introduce a separate, high-priority execution stage for running out-of-band interrupt handlers immediately upon IRQ receipt, which cannot be delayed by the regular kernel work.
There are two flavors of patches available: Dovetail for kernels starting with 5.10 and I-pipe for older kernels.
Dovetail-enabled kernels are available here: https://source.denx.de/Xenomai/linux-dovetail
Released I-pipe patches can be downloaded from: https://xenomai.org/downloads/ipipe
The current development trees (starting from kernel 4.14) for the I-pipe are available from:
The legacy development tree (up to kernel 4.9) can be reached at this URL.
