[Xen-devel] [PATCH] AMD IOMMU: Rework of interrupt remapping
Hi, Attached patch reworks interrupt remapping for following purposes: 1) Parsing IVRS special device entry in order to handle ioapic remapping correctly. 2) Allocating per-device interrupt remapping tables instead of using a global interrupt remapping table. 3) Some system devices like io-apic for north-bridge cannot be discovered during pci device enumeration procedure. To remap interrupt of those devices, device table update is splitted into 2 steps, so that interrupt tables can be bound to device table entry earlier than I/O page tables.
