Embedded hardware, desktop, server. This said, Xenomai has a strong focus on embedded systems, and most Xenomai ports nowadays target those platforms.
In Xenomai parlance, the I-pipe and Adeos both refer to the very same code, that makes a Linux kernel able to host a secondary kernel exhibiting real-time properties (e.g. Xenomai), on the same hardware.
This code is a kernel patch applied to a regular Linux kernel, which among other services, guarantees delivery of external interrupts to Xenomai with very low latency.
|You need the I-Pipe only for running Xenomai in a dual kernel configuration, i.e. over the Cobalt core.|
Check there for an I-pipe patch which best fits your kernel.
To understand that, you should first know that Xenomai is some sort of Chameleon RTOS at its core, which can export multiple real-time APIs to applications, all built over the Xenomai nucleus.
A Xenomai API can impersonate an existing traditional RTOS interface such as VxWorks (tm), or provide an original programming interface for some particular purpose, such as RTDM.
Basically, each API makes Xenomai look a different RTOS albeit all of them are based on the same common core. This is the reason why we call an implementation of such API, a Xenomai skin.
Yes, definitely. Debugging a Xenomai application in a dual kernel system is no different from debugging any regular application.
|The only side-effect of using GDB for debugging a Xenomai application is that breakpointing and single-stepping implies a switch to secondary mode (i.e. threads are automatically handed over the Linux kernel as soon as GDB regains control).|
$ cd xenomai-3 $ ./scripts/bootstrap ... configure.ac:93: error: possibly undefined macro: LT_SYS_SYMBOL_USCORE If this token and others are legitimate, please use m4_pattern_allow. See the Autoconf documentation. autoreconf: /usr/bin/autoconf failed with exit status: 1
On Debian-based systems like Ubuntu, you need to install the libltdl-dev package for building Xenomai from sources.
