it may even be the other way round, that nvidia proprietary drivers work better with RTAI than with RT-PREEMPT. With RTAI, the realtime part is really running under it's own kernel in a sense, and doesn't interfere with the rest of the system/kernel that much. It inercepts interrupt requests very early, whereas rt preempt is really intrusive AFAIU. So if you can get the driver shims to compile for a RTAI kernel it might be worth a try. -- Robert Schöftner <[email protected]> _______________________________________________ Emc-developers mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-developers
