Byte 0: 0x48 (special device)
Byte 1 & 2: must be zero
Byte 3: 0 (dte setting)
Byte 4: 0 (handle)
Byte 5 & 6: IOAPIC devfn (14:0.0)
Do you mean *bus* devfn? devfn is 0.0.
Sorry my bad, I was meaning to write

Probably it shouldn't be a 'typically' device

When interrupt remapping is enabled, add a special IVHD device
(type IOAPIC) -- which is typically PCI device 14:0.0. Linux IOMMU driver
checks for this special device.
