Well as was mentioned recently on the list, if you use the nvidia kernel modules, then you really can not expect xenomai/ipipe to work properly, because you can't fix what the binary blob from nvidia does, and it could easily mess up interrupt handling and make the realtime stop being realtime. -- Len Sorensen _______________________________________________ Xenomai mailing list [email protected] http://www.xenomai.org/mailman/listinfo/xenomai
