Thanks. By the way, does the HCA work in this system? Does it work
with MSI-X? Can you share which motherboard you're using?
I was curious to see the HyperTransport capabilities in the nForce4
PCIe bridge, specifically to see whether it reports an "MSI Mapping"
HT capability.
Unfortunately checking this requires a dump of the whole PCI tree, not
just the HCA part. Fortunately I did receive a dump of an nForce4
system and it does show that the bridge has an MSI Mapping cap, which
means that there's hope of using MSI-X on nForce4 systems. However,
the dump was for an unreleased preproduction system so I can't share
it yet.
Thanks,
Roland
