First, no one seems to want a register based solution for tracking
memory changes.  So I feel the point should rather be to prove why is
sticking some migration features in registers and using dma for others
makes sense.  Second I guess we could have a register based interface
for admin commands, no?

I really wish both of you guys started looking for solutions that
satisfy all use-cases instead of just going head to head. Lingshan that
is why I asked you to try and list advantages of the architecture in
Parav's patches. Do you think you could try and address more use-cases?
