I do not know if it is what you mean, but when running Xenomai, your
tasks are supposed to suspend sufficiently frequently to leave Linux
tick normally. This means that if you configured CONFIG_HZ=100, your
real-time activity (including kernel-space tasks and user-space tasks in
primary mode) is supposed to take a break at least once every 1/100
second.
