I'm a bit confused by this one. The previous patch comment implies it's a preparation for this, but then you add the new irq property to the BusInfo, rather than to the macro that goes into the DeviceInfos. Why does this one go in the bus, rather than the device? > > Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> > Cc: Alexander Graf <agraf@suse.de> > Cc: David Gibson <david@gibson.dropbear.id.au> > Signed-off-by: Alexander Graf <agraf@suse.de> > --- > hw/spapr_vio.c | 8 +++++++- > 1 files changed, 7 insertions(+), 1 deletions(-) > > diff --git a/hw/spapr_vio.c b/hw/spapr_vio.c > index ba2e1c1..0546ccb 100644 > --- a/hw/spapr_vio.c > +++ b/hw/spapr_vio.c > @@ -52,6 +52,10 @@ > static struct BusInfo spapr_vio_bus_info = { > .name = "spapr-vio", > .size = sizeof(VIOsPAPRBus), > + .props = (Property[]) { > + DEFINE_PROP_UINT32("irq", VIOsPAPRDevice, vio_irq_num, 0), \ > + DEFINE_PROP_END_OF_LIST(), > + }, > }; > > VIOsPAPRDevice *spapr_vio_find_by_reg(VIOsPAPRBus *bus, uint32_t reg) > @@ -604,7 +608,9 @@ static int spapr_vio_busdev_init(DeviceState *qdev, DeviceInfo *qinfo) > } > > dev->qdev.id = id; > - dev->vio_irq_num = bus->irq++; > + if (!dev->vio_irq_num) { > + dev->vio_irq_num = bus->irq++; > + } > dev->qirq = spapr_find_qirq(spapr, dev->vio_irq_num); > > rtce_init(dev);

Why does this one go in the bus, rather than the device? Yes, I suppose that the commit message for patch 2 is a bit stale. I put this one in the bus, rather than the device, because the default is common to all devices. Instead, each device type has its own default reg and default dma-window. Paolo
