While the idea of QEMU for this work is attractive it will be a long time before QEMU is in a position to support this development. 

Another approach is to propose a common development platform for p2pmem work using a platform we know is going to work. This an extreme version of the whitelisting approach that was discussed on this thread. We can list a very specific set of hardware (motherboard, PCIe end-points and (possibly) PCIe switch enclosure) that has been shown to work that others can copy for their development purposes.

p2pmem.io perhaps ;-)?
