Why does my build fail with “error: isa_virt_to_bus_is_UNSUPPORTED undeclared”?
Certain drivers (primarily for ISA devices) do not work with Xen due to the restricted memory addresses that the device can access. For most of these drivers we report the error you have seen, in preference to failing weirdly at run time. We aim for Xen to support all modern x86 hardware: this restriction applies only to a few old NICs and disc controllers.
