where an interrupt (irq) can be specified in the configuration file and permission to bind to that interrupt will be given to a driver domain. This functionality could be used when trying to give a legacy device to a driver domain. For example, by specifying the i/o ports and the interrupt of your serial controller, you can use this patch to put a serial port in a driver domain. This was discussed briefly on xen-users in regards to using an external modem in a domU: http://article.gmane.org/gmane.comp.emulators.xen.devel/20573 http://article.gmane.org/gmane.comp.emulators.xen.user/8754 Also adds the ability to specify irqs on the xm command-line when creating a domain (the following examples show a serial port being given to a domU): xm create serial-dd irq=4 ioports=03f8-03ff or in a flat config-file: irq = [4] ioports = ['03f8-03ff'] or in an SXP config file: (device (irq (irq 4))) (device (ioports (from '0x03f8')(to '0x03ff'))) The ioports functionality is already in xen, but this patch also fixes a bug with it that I assume cropped up due to changes in xend since it was submitted ('dev' doesn't exist in iopif.py, returning 'None' seems to be the solution). Also adds some in-line documentation in tools/python/xen/xm/create.py to be more accurate regarding adding pci devices and i/o ports on the command-line.
