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. -- Gilles Chanteperdrix. Oh no! Sorry, I mean the real-time tick counter! But if my real-time activity don't take a break during a while (more than 1/100 second), Is it dangerous for my real-time activity?
