Guy, I tried your patches with a bnx2 NIC on SLES10 and they didn't work. The first reason was that you mask off the capabilities bit in the PCI status. If I got rid of this, I could at least get the NIC to configure, but it didn't work and the dropped packets looked to be random garbage, so I don't think it was talking to the device properly. (But I understand almost nothing about PCI device configuration, so I don't know what to look for.) I haven't noticed the merge tree springing into existence into on xenbits, so is there any progress on making into a real feature? It sounds like most of the work needs to be done between you and Intel, but I could certainly help with testing. One thing I am interested in is, with the 1:1 mapping, could we disable the VT page-fault handling? I've found that the page-fault overhead for VT is horrible and would probably affect fork-exec benchmarks significantly.
