But the directory does not exist, only /proc/xenomai/registry/ exists. What could be the problem? Is a special kernel configuration required or does a special kernel module need to be loaded?

You can check that via smokey's xddp test. If that is not the case, compare configuration and versions of the reference xenomai-images against your setup and share your findings.

They were using Xenomai 2 before and now have switched to Xenomai 3.1. They were using the function rt_pipe_create in Xenomai 2, is there anything different in Xenomai 3? We have set the following kernel configuration für XDDP: CONFIG_XENO_DRIVERS_RTIPC=m CONFIG_XENO_DRIVERS_RTIPC_XDDP=y CONFIG_XENO_DRIVERS_RTIPC_IDDP=y CONFIG_XENO_OPT_IDDP_NRPORT=32 CONFIG_XENO_DRIVERS_RTIPC_BUFP=y CONFIG_XENO_OPT_BUFP_NRPORT=32 Is there anything else needed?

Furthermore, the registry entry is visible as long as you keep the application running (the version you provided deletes it immediately because it shuts down immediately).
