Let's make "MEMHP_MERGE_RESOURCE" consistent with "MHP_NONE", "mhp_t" and
"mhp_flags". As discussed recently [1], "mhp" is our internal
acronym for memory hotplug now.

This backend acts as the counterpart to the Vdmabuf Virtio frontend.
When it receives a new export event from the frontend, it raises an
event to alert the Qemu UI/userspace. Qemu then "imports" this buffer
using the Unique ID.
As part of the import step, a new dmabuf is created on the Host using
This driver "transfers" a dmabuf created on the Guest to the Host.
A common use-case for such a transfer includes sharing the scanout
buffer created by a display server or a compositor running in the
Guest with Qemu UI -- running on the Host.
The "transfer" is accomplished by sharing the PFNs of
After registering with this notifier, other drivers that are dependent
on KVM can get notified whenever a VM is created or destroyed. This
also provides a way for sharing the KVM instance pointer with other
drivers.

The Virtual dmabuf or Virtio based dmabuf (Vdmabuf) driver can be used
to "transfer" a page-backed dmabuf created in the Guest to the Host
without making any copies. This is mostly accomplished by recreating the
dmabuf on the Host using the PFNs and other meta-data shared by the guest.
