Not "play with IOMMU" but use pci_map_single() etc. The PCI address may change but as long as it is in the low 0xffffffffffffffff part of memory we're fine. - Roland _______________________________________________ openib-general mailing list [EMAIL PROTECTED] http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
