Sorry for the inconvenience,
I tried to write this code to report domain changes (or mode switch):
##
#include
#include

#include
RT_TASK task;
void task_body(void *arg)
{
RT_TASK_INFO info;
perfect thank you so much for the explanation

is it possible to have the same thing for tasks instead of threads?

was a way to count the number of times a
domain switch happens.
For example the printf () function causes a domain switch, right?

For example the printf () function causes a domain switch, right?

Hi all,
In my project I'm accessing a device using a linux device driver (via sysfs) .
In order to speedup the control loop I've mmapped the register i need to read.
The question is: If I access a device register using mmap from a xenomai task
am i triggering a domain switch ?

mmaped memory here,
from a xenomai task am i triggering a domain switch ?
No, unless you take a fault doing so, which should not happen if the MMR
is properly mapped/accessed.
BR,
Giuseppe
