Sorry for that. The beginning of the thread is archived here: http://lists.xensource.com/archives/html/xen-devel/2007-07/msg00209.html Although, the last two posts are missing. If you like to get bounced whole thread, I can do it. Right now, I have problem in :ib_mthca:mthca_arbel_write_mtt_seg where dma_sync_single is called and swiotlb does not have corresponding mapping. -- Lukáš Hejtmánek _______________________________________________ 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
