One more question about the CLOCK_RTL_SCHED. I just can't find any characteristics about this clock, except it's the clock used by the scheduler for task scheduling. I would like to know a little bit more about it, especially in terms of precision.
Thank you
Sebastien

I'm starting progamming rtlinux and I have questions about the different
clocks that can be used :
- while using the "gethrtime();" instruction, where does the value
returned come from ? the CPU ? an other clock ?
gethrtime() uses the CPU clock.- when I write :
rtl_setclockmode(rtl_getschedclock(),RTL_CLOCK_MODE_ONESHOT)); which
clock is used ? Man-pages say : rtl_getschedclock returns the clock id
of the clock that the realtime scheduler uses on the local CPU, but what
is that clock ?
This is CLOCK_RTL_SCHED.
Michael.
