Xenomai 2 to 3 migration says "RTDM drivers implementing differentiated ioctl() support for both domains should serve all real-time only requests from ioctl_rt(), returning -ENOSYS for any unrecognized request, which will cause the adaptive switch to take place automatically to the ioctl_nrt() handler. The ioctl_nrt() should then implement all requests which may be valid from the regular Linux domain exclusively."

This is a minimal example module for the use of the EtherCAT master realtime
interface with an RTAI thread.
The module expects an RTAI installation. Configure the master sources
specifying --with-rtai-dir to have the right include paths.
Most probably you'll have different EtherCAT slaves present. Try adjusting the
section "process data" in rtai_sample.c to your bus configuration.
There are some features that can be disabled by commenting out the respective
defines at the head of rtai_sample.c.
---
To build the example module, call:
make modules
To run it, load the appropriate RTAI modules and call:
insmod ec_rtai_sample.ko
...and watch the system logs for the outputs.
