Hi,

Could any body explain the native task managment api rt_task_slice &
rt_task_set_mode?
How these are useful, please explain with example?

I tried to set a time slice for a particuler rt task through rt_task_slice
but could not get much.

Thanks in advance,
Manoj

There is no example of how the round-robin mode works. The information
which is not obvious and which you are probably missing is that the
round-robin mode only works if the system timer is set to periodic mode.

To set the system timer to periodic mode, set the configuration option
CONFIG_XENO_OPT_NATIVE_PERIOD to a non null value, or use rt_timer_set_mode.
