Hi,
I found a problem with rt_task_set_priority function which does not
increase priority of another task.
However it works fine if you increase the priority of another task.
Below is an en example program and its output, and we run this program
on xenomai 3.08.
The problem appears if we run the program on our xenomai image for the
raspberry pi 3,
and is also appears in our virtual box image.
Both images can be found at :
* http://www.cs.ru.nl/lab/xenomai/raspberrypi.html
* http://www.cs.ru.nl/lab/xenomai/virtualbox.html
The easiest way is to run the virtualbox image.
The final question I have: is there an wrong usage of xenomai API in the
example program,
or is this a bug in xenomai?
Something is inconsistent here. Did you also check via
/proc/xenomai/sched/threads if that view is consistent with the result
of inquire? I vaguely recall issues of the latter but I also do not
recall any fix to 3.1, not to speak of anything that was not backported.
BTW, tried 3.1 as well?
