I don't think that there are any plans to do this. The main challenge is the testing associated with such a large change. Even if the implementation too a couple of weeks, getting good test coverage would be a nightmare. Perhaps we could build an i86xpv variant of the driver that didn't use inb/outb. We'd have to manage any divergence carefully. _______________________________________________ xen-discuss mailing list [email protected]
