I don't know if you take that into account. Actually I would suspect that it doesn't. If you look at drivers/char/mem.c, you can see that there's nothing there to set up the IOMMU, so I don't think access to PCI space will work -- a simple remap_pfn_range won't work (sparc64 doesn't even define pgprot_noncached). - R. _______________________________________________ openib-general mailing list [email protected] http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
