Yeah, I always kinda wondered why this wasn't done automatically by pciback. Having pciback do it would mean that even non-BAR aligned devices could be exported after booting and w/out specifying PCI IDs as kernel args. That would be one fewer issue to fix later in the upstreaming effort. -Mike _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
