[RTnet-users] ORTE-RTnet-LXRT Questions

[George Doukas]

Hello everybody...

I've been working with RTnet over RTAI/LXRT for sometime and now I'm in a process to integrate ORTE to my work...

Although I've studied the provided ORTE documentation and some portions of the source code there are some issues that are not 100% clear to me and would appreciate if you could help clear them out.

First of all I assume that ORTE (liborte) supports real-time operation over RTnet in userspace through LXRT. Is this true?
If this is actually true then in order to use ORTE from real-time LXRT threads is it required to insmod orte_rt and ortemanager_rt modules kernel or not?

I' asking this because I've allready used orte from within LXRT real-time threads (after calling rt_make_hard_real_time) without having the 2 modules loaded (ortemanager runs as normal process) and this scheme seems to work...
The reason why I followed this scheme is because I could not load ortemanager_rt module... each time I try to insmod ortemanager_rt the system freezes!
I've found an older post about a similar problem and the solution proposed was to pass the parameter rtskb_cache_size=64 when loading rtnet.o. That did not work for me!
Any sugestions?


Thank you in advance!
George.
