Hello all, I, working on AMD IOMMU interrupt remapping would like to ask some questions on Qemu IOAPIC id.
I currently have a problem in that Linux AMD IOMMU driver expects at least one IOAPIC on the chipset to have ID 0xa0 while Qemu IOAPIC id is always 0. I am faced with two options -Change IOAPIC id so that it always matches what Linux AMD IOMMU driver expects. In this case I am not sure which problems I could encounter with this approach. -Have a way to configure IOAPIC ID based on emulated IOMMU. I prefer the first approach since it's quite simple but would like to hear other opinions regarding this issue. David.
