[RFC] virtio-mem: paravirtualized memory
...certain types. E.g. if we want to expose PMEM memory region to a guest using a paravirtualized interface (or anything else that can be mapped into guest memory in the form of memory regions), we could use this. The guest->host control queue can be used for tasks that typically cannot be done if moddeling something like this using ordinary ACPI DIMMs (flushing etc). CCing a couple of people that just thought about something like this in the concept of fake DAX.

[RFC] virtio-mem: paravirtualized memory
Hi, this is an idea that is based on Andrea Arcangeli's original idea to host enforce guest access to memory given up using virtio-balloon using userfaultfd in the hypervisor. While looking into the details, I realized that host-enforcing virtio-balloon would result in way too many problems (mainly backwards compatibility) and would also have some conceptual restrictions that I want to avoid.
