It's possible for both the frontend and backend drivers to declare capabilities that can be discovered and used by their peer (the 'feature-' and 'request-' flags in xenstore). If you have a specific capability in mind then it should be possible to express it with this. > And find some methods to enhance the networking performance on the xVM > Do you have some suggestion? My current performance work is at http://dme.org/solaris/webrev/txcopyop You should use it as a basis for further work, as I'll integrate it into Nevada soon after the Xen 3.3 putback. The immediate things that I planned to do after this are: - scatter gather support, - large send/receive offload support. The latter should help bulk throughput significantly (currently struggling to reach 3Gbit/s). After that the ideas are much more invasive: - add support for using multiple rings and interrupt channels, - implement netchannel2, - ... Did you have any specific ideas in mind? dme. -- David Edmondson, Sun Microsystems, http://dme.org _______________________________________________ xen-discuss mailing list [email protected]
