Hi!
I'm running Xenomai on Raspberry Pi 3 given by: http://www.cs.ru.nl/lab/xenomai/ and I
have some questions.
Where can I find information on how often the system timer interrupts for scheduling
regarding rt tasks? When using command "dmesg | grep pipe -i" I get :
"[ 0.000000] I-pipe, 19.200 MHz clocksource, wrap in 960767920505705 ms
[ 0.000000] clocksource ipipe_tsc: mask: 0xffffffffffffffff max_cycles: 0x46d987e47,
max_idle_ns: 440795202767 ns
[ 0.000894] Interrupt pipeline (release #9)
[ 0.171104] Switched to clocksource ipipe_tsc"
Is the frequency 19.200MHz how often the scheduler will execute?
Regards,
Gustav Johansson
