2017-07-05 Thread Cédric Le Goater
This is very similar to the current ICS_SIMPLE model in XICS. We try to reuse the ICS model because the sPAPR machine is tied to the XICSFabric interface and should be using a common framework to switch from one controller model to another: XICS <-> XIVE. The next patch will introduce the MMIO
