[Xenomai-core] userspace applications and cache

[Steven Seeger]

If a userspace application running xenomai threads is large (1MB or  
so) then the code can't all live in cache on our puny 16kb instruction  
cache. Does the cache handling occur as needed in the primary domain  
or does it have to wait for Linux to handle it?

Thanks,
Steven

You should use the I-pipe tracer, it will tell you exactly what happens
on your system.
