Given hardware support, just using UC is easy. The largest bit of work would be to add connection liveness detection code to active side. Hopefully not too bad either. > Is there any --other-- part of the stack (eg mthca,cm) that needs to be > enhanced for that? Not a whole lot. We need an API to detect this feature support in HW. There could be a bit of work in mthca to detect HW/FW support for this feature, and enable connecting UC QPs to SRQ. There could be a bit of debugging work in CM in case we hit some bugs with LAP messages (which I plan to use for liveness detection). -- MST _______________________________________________ general mailing list [email protected] http://lists.openfabrics.org/cgi-bin/mailman/listinfo/general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
