Also we ought to document the ports in xen-platform-pci's source file, as it's going to start getting messy in there. I'm not sure if the approach taken by the Citrix drivers could be at all useful. Cc'ing Steven Smith in case he has any comments to make. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
