Hello! I have seen that the Qemu code contains some nice code for PCI bus emulation. I wonder whether this code could be reused in XEN to fake a PCI bus by running the PCI emulation code in an exception handler in the hypervisor and setting a user domain''s IO privilege level appropriately to have all inb/outb''s intercepted. This could have potential benefits on the build process of user domains which could include the PCI code when built, but that code when probing the PCI bus would only find an empty bus and the probing of the drivers in the kernel would not start. Maybe this code could also be used to support driver domains. Is this a good idea? :-) Stefan _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
