[Xen-devel] AMD IOMMU intremap tables and IOAPICs

[George Dunlap <George.Dunlap@xxxxxxxxxxxxx>]

Wei,

Quick question:  Am I reading the code correctly, that even with
per-device interrupt remap tables, that GSIs are accounted to the
intremap table of the corresponding IOAPIC, presumably because the
IOMMU sees interrupts generated as GSIs as coming from the IOAPIC?  In
that case, then we need all devices sharing the same IOAPIC must not
have any vector collisions.  Is that correct?
