coherent and consistent are synonyms. It's confusing because there is pci_alloc_consistent(), which is in general just a wrapper for dma_alloc_coherent(). > And moreover, it avoids using swiotlb and bounce buffers, I think.

Yes, but I'm not really willing to make things worse for standard i386 just to make Xen work a little better. - 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
