IIRC q35 supports memory hotplug natively (picked up in some discussion). Is that correct?
From previous discussion I also understand that q35 supports native hotplug. Sections 5.1 and 5.2 of the spec describe the MCH registers but the native memory hotplug specifics are not yet clear to me. Any pointers from the spec are welcome.
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: http://www.intel.com/design/chipsets/datashts/316966.htm
Is the q35 memory hotplug support supposed to be an shpc-like interface geared towards memory slots instead of pci slots?
I think there is no dedicated pci express downstream port for memory slots, so native plug is not available.
thanks,
