Ping. Could anyone who's familiar with the q35 spec provide some pointers on
native memory hotplug details in the spec? I see pcie hotplug registers but can't
find memory hotplug interface details. If I am not mistaken, the spec is here:

Is the q35 memory hotplug support supposed to be an shpc-like interface geared
towards memory slots instead of pci slots?
