[Xen-devel] Permissive devices in Xen



Hello,

is there any reason why even permissive devices cannot write some areas in the 
PCI config space?

The PCI_COMMAND is handled in special way so that the device is
enabled/disabled properly, am I right?

Why is PCI_INTERRUPT_LINE read from dev->irq and not from the config space?

Why the PCI address bars are handled in very different way? And it seems that
writing these bars is never committed to the real devices. Why?

Thanks for answers.
