[Xen-devel] [PATCH] AMD IOMMU: Rework of interrupt remapping

[Wei Wang2 <wei.wang2@xxxxxxx>]

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.
Thanks,
-Wei
