At least dom0 parses this info from DSDT, so we can't have the assuption whether
it is used or not, I think. And I also agree to add a new physdev_op to handle
this case, and it should be better way to go.
Based on this idea, I worked out the patch, attached! In this patch, we
introduced a new physdev_op PHYSDEVOP_setup_gsi for each GSI setup, and each
domain can require to map each GSI in this case.
In addition, I believe it is very safe to port the hypervisor patch to xen-3.4-x
tree and keeps pv_ops dom0 running on it, since no logic is changed. BTW, I
also tested apic and non-apic cases, they works fine after applying the patches.
But I don't think you tested PCI front and PCI back.
Mainly these lines worry me (can you inline the patch next time too, please):
+ map_irq.domid = DOMID_SELF; + map_irq.type = MAP_PIRQ_TYPE_GSI; + map_irq.index = gsi; + map_irq.pirq = irq; + rc = HYPERVISOR_physdev_op(PHYSDEVOP_map_pirq, &map_irq);
For PCI passthrough to work, the domid needs to be for the guest domain, while in this case it is set to Dom0.
There is already a method of extracting the domain id for PCI devices passed to the guest. Look in the 'xen_create_msi_irq' function.
