Absolutly correct! However, if you are running the system on an embedded platform, where the _WHOLE_ system (including priorities) is preconfigured and never touched, starting a irq thread with the right prio from start is a more straightforward method than having to invoke a script that changes it using userspace chrt tool.

No you don't. How does you driver know about what priority is correct wrt all the other running RT tasks on the system? Determining the right priority in a fixed priority scheduling system is a system wide problem, nobody but the administrator can possibly even begin to solve it. There's a reason all RT irq threads are started at 50, its plain impossible to do better. -- To unsubscribe from this list: send the line "unsubscribe linux-rt-users" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html -- To unsubscribe from this list: send the line "unsubscribe linux-rt-users" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
