If your application based on 0.9.1 used to run in user-space, then it
must have been based on the UVM support. This support has been dismissed
since Xenomai v2.3-rc1, because it was a temporary hack allowing
user-space development until all skins have a real user-space interface,
which is now the case.

The services you mention are now only available from the kernel-based
interface, provided by the xeno_vxworks.ko module, because they do not
make sense from a userland perspective.

Userland applications based on the VxWorks API
(/usr/xenomai/lib/libvxworks.so) should not need them at all. If for
some reason they do, then you should consider splitting the application
in two parts, one kernel-based, the other one running in userland. The
point is that dealing with interrupts should most often remain a kernel
business, and this obviously also applies to interposing on the tick timer.

If your application was not based on the UVM, then it must have been
running embodied into a kernel module, in which case the issue is
already solved.

Rehashing what Gilles already told you: until you actually explain _why_
you need such services, nobody will be able to suggest any solution to
your problem, I'm afraid.
