Hi, I have some questions regarding pthread and NATIVE API... I use xenomai 2.4.8 with native API and RTDM services in a linux 2.6.28 lite5200 embedded platform. My application creates several realtime tasks (rt_task) using native api, inside a linux environment with other applications. All worked fine, till I need to create, from any of this rt_task, some nonrealtime tasks to do a long and not priority jobs (parse huge xml files, compress / uncompress them...). To do that, I use pthread_create(), to create a non realtime task with the "default attributes". I expected that this pthread would share the remaining CPU time with the other linux applications. But it seems that this new pthread created has higher priority than any of the other non-RT linux apps. The feeling is that the CPU is shared only between the realtime tasks and this pthread: for instance, one of the other non-RT apps controls the watchdog, and it resets the system some seconds after the pthread is created. If I call pthread_getschedparam inside the pthread I get thread prio = 0, and SCHED_OTHER. I tried using __real_pthread_create as well, and had the same result.
Is correct to use pthread_create to create a new non-RT task from a rt_task? Which are the attributes/priority of that pthread? Does it inherit some of the RT parent "privileges"?
