Greetings,

I am about to restart dabbling with xenomai on a cblfs x86_64/64-bit machine .  
I have a question. Could one have multiple instances of kernels  
patched/compiled/installed  thus  multiple instances of /lib/modules-xyz  AND 
a single instance of xenomai in userspace  that works with all of them?

Advice would be appreciated.


yours sincerely
lux-integ

The answer to your question is that the ABI is compatible between the
kernel-space and user-space. This means:
- kernel-space and user-space must be from the same branch, say,
kernel-space version 2.5.x with user-space version 2.5.y;
- they must be configured with compatible options, the said options
being dependent on the architectures and being described in the
README.INSTALL document:
http://www.xenomai.org/documentation/xenomai-2.5/README.INSTALL
