So, let me try to understand ... your hardware allows writes from the device to pass other writes from the device? Doesn't that violate the PCI spec? I'm thinking about this (page 43 of PCI 2.3):
Hi Matthew, Yes I believe this behavior on sn2 is 'bending' the PCI spec a bit. The problem is that the NUMA fabric is a routed network in itself so there can be multiple paths between the device and the physical memory it DMAs to/from.
