[Xen-devel] What happens when turning off CONFIG_XEN_DISABLE_SERIAL?



This option seems fairly odd, especially because it doesn't only disable access 
to
the serial port in use by Xen (and even that only optionally), but to all 8250 
style
ones. I would want to reach a state where all ports are available to guests
except for the at most one port Xen may use for its console (plus perhaps any
others sharing the IRQ with it, although I can't see how Xen would be able to
properly show their unavailability).
But due to the lack of experience with the xen console code (and also more
generally the Linux one) I can't really judge whether turning off $subject 
config
option will have any ill effect here, while I'm pretty convinced that it would 
help
the situation described above. In particular I wonder whether xc_mode
shouldn't default to XC_OFF in dom0 when that config option is off.

Thanks for any suggestions or hints,
Jan
