Yes, it is in a prefetchable BAR. It's the second half of the second
BAR in:
0d:00.0 InfiniBand: Mellanox Technologies Unknown device 634a (rev a0)
Subsystem: Mellanox Technologies Unknown device 634a
Flags: bus master, fast devsel, latency 0, IRQ 16
Memory at fc400000 (64-bit, non-prefetchable) [size=1M]
Memory at d8000000 (64-bit, prefetchable) [size=8M]
Memory at fc3fe000 (64-bit, non-prefetchable) [size=8K]
Capabilities: <access denied>
but I'm not sure what you mean about combining several cards?
