This is the framework for using XIVE in a PowerVM guest. The support
is very similar to the native one in a much simpler form.

Instead of OPAL calls, a set of Hypervisors call are used to configure
the interrupt sources and the event/notification queues of the guest:

   H_INT_GET_SOURCE_INFO
   H_INT_SET_SOURCE_CONFIG
   H_INT_GET_SOURCE_CONFIG
   H_INT_GET_QUEUE_INFO
   H_INT_SET_QUEUE_CONFIG
   H_INT_GET_QUEUE_CONFIG
   H_INT_RESET

Calls that still need to be addressed :

   H_INT_SET_OS_REPORTING_LINE
   H_INT_GET_OS_REPORTING_LINE
   H_INT_ESB
   H_INT_SYNC

So, does this mean there's a PAPR update with the XIVE virtualization
stuff?  Or at least an ACR?  Can we have that available please...

The QEMU patchset has some initial info on the hcalls :
