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? -George _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
