"coherent" seems like the wrong name here... really the property being asked for is "flush other in-flight DMAs" or something like that (I don't know precisely what setting the magic bit in the DMA address does on Altix). Also maybe it would make more sense to fold this into the existing direction parameter somehow, so that most of the kernel can stay unchanged (because as far as I know, Altix is the only platform that has this extra quirk of allowing DMAs to pass each other). - R. _______________________________________________ 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
