[Xen-devel] [VTD][PATCH] Support intra-domain shared interrupt

["Han, Weidong" <weidong.han@xxxxxxxxx>]

Inter-domain shared interrupt has been supported by timeout method, but
it still doesn't support intra-domain shared interrupt, that is
assigning multiple devices which share a physical irq to the same
domain. This patch implements intra-domain shared interrupt support. In
addition, this patch maps link to guest device/intx instead of directly
mapping isairq in pt_irq_create_bind_vtd(), because at this point the
isairqs got from pci_link are always 0. 

Note that assigning multiple devices to guests which uses PIC to handle
interrupts may be failed, because different links possibly connect to
same irq.
