Hi,
This series proposes a new solution: helpers that reconfigure existing
ISADevices.
It also contains a resend of a prerequisite patch with updated summary.
As for the remaining issue of enabling/disabling devices I'd like to hear
opinions on whether we should allow hot-plugging of these devices or
whether we should add an enabled/disabled state to a qdev device.
I'd tend to think having a enable/disable state (and a setstate callback
in ISADeviceInfo) is easier to handle, especially wrt the host-side
state of the device (i.e. the chardev).
Reconfiguration can be done this way then:
setstate(0) -> device unregisters irq + ports.
qdev_prop_set_*() -> updates iobase + irqs
setstate(1) -> device registers new irqs + ports.
cheers,
Gerd
