Hi Roland,

Thanks. By the way, does the HCA work in this system? Does it work with MSI-X?
I haven't had a chance to do much testing on this. most of the testing that has been done is with gen1. i have compiled gen2 in there at the moment and i see the appropriate ib0, /proc/infiniband, etc. i may be able to do a little testing with this later in the week.
Can you share which motherboard you're using?
it is one that we've built ourselves.
I was curious to see the HyperTransport capabilities in the nForce4 PCIe bridge, specifically to see whether it reports an "MSI Mapping" HT capability.
okay.
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.
okay, no problems.
