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
=========================
The complete design can be found at
https://lists.xenproject.org/archives/html/xen-devel/2016-07/msg01921.html.
All patch series can be found at
Xen: https://github.com/hzzhan9/xen.git nvdimm-rfc-v1
QEMU: https://github.com/hzzhan9/qemu.git xen-nvdimm-rfc-v1
Linux kernel: https://github.com/hzzhan9/nvdimm.git xen-nvdimm-rfc-v1
ndctl: https://github.com/hzzhan9/ndctl.git pfn-xen-rfc-v1
QEMU, as the device model of Xen HVM domU, is responsible to
1) build NVDIMM ACPI tables and namsepace devices, and
2) find proper areas in the guest physical address space to place
vNVDIMM devices. The backend resources of vNVDIMM are managed by
Xen rather than QEMU.
Patch 02 - 05 implement above 1). They implement a mechanism to pass
guest ACPI tables and namespace devices to Xen guests.
Patch 06 - 08 implement above 2). Because the backend resources of
vNVDIMM devices for Xen guest is managed out of QEMU, we introduce a
new host memory backend memory-backend-xen to be used with vNVDIMM
devices. It basically plays as a placeholder, which can fit in the
current pc-dimm code and only gets the guest address ranges of vNVDIMM
devices. The guest address ranges as well as other information of
vNVDIMM devices are passed to Xen via a new QMP command.
Because labels are not supported for Xen guest now, Patch 01 is needed
to avoid dereferencing the NULL pointer to non-existing label data.
How to test
===========
Please refer to the cover letter of Xen patch series
"[RFC XEN PATCH 00/16] Add vNVDIMM support to HVM domains".
Haozhong Zhang (8):
01/ nvdimm: do not initialize label_data if label_size is zero
02/ xen-hvm: add a function to copy ACPI to guest
03/ nvdimm acpi: do not use fw_cfg on Xen
04/ nvdimm acpi: build and copy NFIT to guest on Xen
05/ nvdimm acpi: build and copy NVDIMM namespace devices to guest on Xen
06/ hostmem: add a host memory backend for Xen
07/ xen-hvm: create hotplug memory region for HVM guest
08/ qmp: add a qmp command 'query-nvdimms' to get plugged NVDIMM devices

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.

Is this an particular patch in this series that does that?
You may want to enumerate which one it is.

Build and copy NVDIMM namespace devices to guest when QEMU is used as
the device model of Xen. Only the body of each AML device is built and
copied, Xen hvmloader will build the complete namespace devices from
them and put in SSDT tables.

Build and copy NVDIMM namespace devices to guest when QEMU is used as
the device model of Xen. Only the body of each AML device is built and
copied, Xen hvmloader will build the complete namespace devices from
them and put in SSDT tables.

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 (memory-backend-xen) which plays as a placeholder and
does not map any backend resource. Therefore, those devices when used on
Xen just needs to use the new backend.
Following is an example of the command options of an NVDIMM device using
a file backend on Xen:
-object memory-backend-xen,id=mem1,mem-path=$FILENAME,size=$SIZE
-device nvdimm,id=nvdimm1,memdev=mem1

Needs rebasing - we no longer need SQMP/EQMP sections or callouts to the
initializers, now that commit bd6092e4 has automated the mapping of QAPI
to command registration.

Is this something that can be added to the existing query-memdev or
query-memory-devices command, instead of needing a new command?

Both query-memdev and query-memory-devices do not tell whether a
device is NVDIMM. If adding an optional argument to existing a qmp
command does not break backwards compatibility, I propose to add an
argument "nvdimm" to query-memory-devices which controls whether this
command to return all memory devices or only NVDIMM devices.

query-memory-devices returns a list of MemoryDeviceInfo:
##
# @MemoryDeviceInfo:
#
# Union containing information about a memory device
#
# Since: 2.1
##
{ 'union': 'MemoryDeviceInfo', 'data': {'dimm': 'PCDIMMDeviceInfo'} }
This is a union, designed to be extended for other types of memory
device frontends.
Sadly, it's a "simple" union (I dislike those).
You could add a new member to be used for the NVDIMM case. It would
probably duplicate some or all of PCDIMMDeviceInfo, though.
If it needs all of PCDIMMDeviceInfo, you could make the new member's
type have PCDIMMDeviceInfo as base.
If we can identify information *any* memory device frontend should have,
the appropriate design would be a flat union with common information
common, and type-specific information in union branches. Could
MemoryDeviceInfo be backward-compatibly morphed into such a type?
We also have query-memdev, which is about memory backends.
PCDIMMDeviceInfo member memdev links from the frontend to the backend.
Aside: calling the backends "memdev" and the frontends "memory-devices"
is very bad taste. It's also very traditional for QEMU: we call
everything "device" or maybe "driver".

query-memory-devices returns a list of MemoryDeviceInfo:
##
# @MemoryDeviceInfo:
#
# Union containing information about a memory device
#
# Since: 2.1
##
{ 'union': 'MemoryDeviceInfo', 'data': {'dimm': 'PCDIMMDeviceInfo'} }
This is a union, designed to be extended for other types of memory
device frontends.
Sadly, it's a "simple" union (I dislike those).
You could add a new member to be used for the NVDIMM case. It would
probably duplicate some or all of PCDIMMDeviceInfo, though.
If it needs all of PCDIMMDeviceInfo, you could make the new member's
type have PCDIMMDeviceInfo as base.
If we can identify information *any* memory device frontend should have,
the appropriate design would be a flat union with common information
common, and type-specific information in union branches. Could
MemoryDeviceInfo be backward-compatibly morphed into such a type?
We also have query-memdev, which is about memory backends.
PCDIMMDeviceInfo member memdev links from the frontend to the backend.
Aside: calling the backends "memdev" and the frontends "memory-devices"
is very bad taste. It's also very traditional for QEMU: we call
everything "device" or maybe "driver".

Information so far queried in my patch is just a subset of
PCDIMMDeviceInfo. Additional information (e.g. location of NVDIMM
label area) may be needed in the future, so I would like to add a new
type NVDIMMDeviceInfo with PCDIMMDeviceInfo as base.

Yes, conversion to a flat union is possible without breaking existing
QMP usage. It would look something like this (with anonymous base and
branch classes, which is still one of my pending qapi patches to post):
{ 'enum': 'MemoryDeviceType', 'data': [ 'dimm', 'nvdimm' ] }
{ 'union': 'MemoryDeviceInfo', 'base': { 'type': 'MemoryDeviceType' },
'discriminator': 'type',
'data': { 'dimm': { 'data': 'PCIMMDeviceInfo' },
'nvdimm': 'whatever_type_here' } }
We would still have back-compatible:
{ "type": "dimm", "data": { "addr":..., "size":..., ... } }
for dimm, and for nvdimm, we would have
{ "type": "nvdimm", whatever fields we want here }
whether we want all the fields to be flattened in the nvdimm case, vs.
nested (for back-compat) under a 'data' dict in the 'dimm' case, or
whether we want both uses to be nested under a 'data' dict for
consistency, is a matter of taste.
