The virtio crypto device is a virtual crypto device (ie. hardware
crypto accelerator card). Currently, the virtio crypto device provides
the following crypto services: CIPHER, MAC, HASH, and AEAD.
In this patch, CIPHER, MAC, HASH, AEAD services are introduced.

Add the infrastructure required for the virtio 1.0 "emergency write"
(VIRTIO_CONSOLE_F_EMERG_WRITE) feature. Because we don't touch the
size of the configuration area, guests will not be able to actually
make use of this without further patches.

Some virtual devices (e.g. NVDIMM) use the host memory backend to map
its backend resources to the guest. When those devices are used on Xen,
the mapping has to be managed out of QEMU. In order to reuse other parts
of the implementation of those devices, we introduce a host memory
backend for Xen (
Build and copy NVDIMM namespace devices to guest when QEMU is used as

them and put in SSDT tables.

Xen uses this command to get the backend resource, guest SPA and size of

Overview
This RFC QEMU patch series along with corresponding patch series of
Xen, Linux kernel and ndctl implements vNVDIMM for Xen HVM guests. DSM
(and hence labels) and hotplug are not supported by this patch series
and will be implemented later.
Design and Implementation
==
When memory-backend-xen is used, the label_data pointer can not be got
via memory_region_get_ram_ptr(). We will use other functions to get
label_data once we introduce NVDIMM label support to Xen.
