Peter Maydell bb5ccf225e qapi: Delete all the "foo: dropped in n.n" notes
A handful of QAPI doc comments include lines like
"ppcemb: dropped in 3.1". The doc comment parser will just
put these into whatever the preceding section was; sometimes
that's "Notes", and sometimes it's some random other section,
as with "NetClientDriver" where the "'dump': dropped in 2.12"
line ends up in the "Since:" section.

This tends to render wrongly, more so in the upcoming rST
generator, but sometimes even in the Texinfo, as in the case
of QKeyCode:
   ac_bookmarks
       since 2.10 altgr, altgr_r: dropped in 2.10

Since commit 3264ffced3 (v4.2.0), we have a better place to tell
users about deprecated and deleted functionality --
qemu-deprecated.texi.  These "dropped in" remarks all predate it, and
other feature drops of that vintage are not documented anywhere, so
moving these to qemu-deprecated.texi makes little sense.  Drop them
instead.

Peter Maydell 26ec4e53f2 qapi: Fix indent level on doc comments in json files
The current doc generation doesn't care much about indentation levels,
but we would like to switch to an rST format, and rST does care about
indentation.

Make the doc comments more strongly consistent about indentation
for multiline constructs like:

@arg: description line 1
      description line 2

Returns: line one
         line 2

so that there is always exactly one space after the colon, and
subsequent lines align with the first.

This commit is a purely whitespace change, and it does not alter the
generated .texi files (because the texi generation code strips away
all the extra whitespace).  This does mean that we end up with some
over-length lines.

Note that when the documentation for an argument fits on a single
line like this:

@arg: one line only

then stray extra spaces after the ':' don't affect the rST output, so
I have not attempted to methodically fix them, though the preference
is a single space here too.

Liu Jingqi c412a48d4d numa: Extend CLI to provide memory side cache information
Add -numa hmat-cache option to provide Memory Side Cache Information.
These memory attributes help to build Memory Side Cache Information
Structure(s) in ACPI Heterogeneous Memory Attribute Table (HMAT).
Before using hmat-cache option, enable HMAT with -machine hmat=on.

Tao Xu 244b3f4485 numa: Extend CLI to provide initiator information for numa nodes
In ACPI 6.3 chapter 5.2.27 Heterogeneous Memory Attribute Table (HMAT),
The initiator represents processor which access to memory. And in 5.2.27.3
Memory Proximity Domain Attributes Structure, the attached initiator is
defined as where the memory controller responsible for a memory proximity
domain. With attached initiator information, the topology of heterogeneous
memory can be described. Add new machine property 'hmat' to enable all
HMAT specific options.

Extend CLI of "-numa node" option to indicate the initiator numa node-id.
In the linux kernel, the codes in drivers/acpi/hmat/hmat.c parse and report
the platform's HMAT tables. Before using initiator option, enable HMAT with
-machine hmat=on.

Daniel P. Berrangé 04109957d4 qapi: report the default CPU type for each machine
When user doesn't request any explicit CPU model with libvirt or QEMU,
a machine type specific CPU model is picked. Currently there is no way
to determine what this QEMU built-in default is, so libvirt cannot
report this back to the user in the XML config.

This extends the "query-machines" QMP command so that it reports the
default CPU model typename for each machine.

Igor Mammedov cd5ff8333a machine: show if CLI option '-numa node,mem' is supported in QAPI schema
Legacy '-numa node,mem' option has a number of issues and mgmt often
defaults to it. Unfortunately it's no possible to replace it with
an alternative '-numa memdev' without breaking migration compatibility.
What's possible though is to deprecate it, keeping option working with
old machine types only.

In order to help users to find out if being deprecated CLI option
'-numa node,mem' is still supported by particular machine type, add new
"numa-mem-supported" property to output of query-machines.

"numa-mem-supported" is set to 'true' for machines that currently support
NUMA, but it will be flipped to 'false' later on, once deprecation period
expires and kept 'true' only for old machine types that used to support
the legacy option so it won't break existing configuration that are using
it.
