When dom0 is PVH, and passthrough a device to dumU, xl will use the gsi number of device to do a pirq mapping, see pci_add_dm_done->xc_physdev_map_pirq, but the gsi number is got from file /sys/bus/pci/devices/<sbdf>/irq, that confuses irq and gsi, they are in different space and are not equal, so it will fail when mapping. To solve this issue, to get the real gsi and add a new function xc_physdev_map_pirq_gsi to get a free pirq for gsi. Note: why not use current function xc_physdev_map_pirq, because it doesn't support to allocate a free pirq, what's more, to prevent changing it and affecting its callers, so add xc_physdev_map_pirq_gsi. Besides, PVH dom0 doesn't have PIRQs flag, it doesn't do PHYSDEVOP_map_pirq for each gsi. So grant function callstack pci_add_dm_done->XEN_DOMCTL_irq_permission will fail at function domain_pirq_to_irq. And old hypercall XEN_DOMCTL_irq_permission requires passing in pirq, it is not suitable for PVH dom0 that doesn't have PIRQs to grant irq permission. To solve this issue, use the another hypercall XEN_DOMCTL_gsi_permission to grant the permission of irq( translate from gsi) to dumU when dom0 has no PIRQs.
