b2d7a7c7e4 target/riscv: Implement privilege mode filtering for cycle/instret
Privilege mode filtering can also be emulated for cycle/instret by
tracking host_ticks/icount during each privilege mode switch. This
patch implements that for both cycle/instret and mhpmcounters. The
first one requires Smcntrpmf while the other one requires Sscofpmf
to be enabled.

The cycle/instret are still computed using host ticks when icount
is not enabled. Otherwise, they are computed using raw icount which
is more accurate in icount mode.

b54a84c15e target/riscv: Add cycle & instret privilege mode filtering support
QEMU only calculates dummy cycles and instructions, so there is no
actual means to stop the icount in QEMU. Hence this patch merely adds
the functionality of accessing the cfg registers, and cause no actual
effects on the counting of cycle and instret counters.

68c05fb530 target/riscv: Combine set_mode and set_virt functions.
Combining riscv_cpu_set_virt_enabled() and riscv_cpu_set_mode()
functions. This is to make complete mode change information
available through a single function.

This allows to easily differentiate between HS->VS, VS->HS
and VS->VS transitions when executing state update codes.
For example: One use-case which inspired this change is
to update mode-specific instruction and cycle counters
which requires information of both prev mode and current
mode.

a60ce58fd9 target/riscv: Support Zama16b extension
Zama16b is the property that misaligned load/stores/atomics within
a naturally aligned 16-byte region are atomic.

According to the specification, Zama16b applies only to AMOs, loads
and stores defined in the base ISAs, and loads and stores of no more
than XLEN bits defined in the F, D, and Q extensions. Thus it should
not apply to zacas or RVC instructions.

For an instruction in that set, if all accessed bytes lie within 16B granule,
the instruction will not raise an exception for reasons of address alignment,
and the instruction will give rise to only one memory operation for the
purposes of RVWMO—i.e., it will execute atomically.

it is more reasonable to directly display its compressed name, because

Zcmop defines eight 16-bit MOP instructions named C.MOP.n, where n is
an odd integer between 1 and 15, inclusive. C.MOP.n is encoded in
the reserved encoding space corresponding to C.LUI xn, 0.

Unlike the MOPs defined in the Zimop extension, the C.MOP.n instructions
are defined to not write any register.

In current implementation, C.MOP.n only has an check function, without any
other more behavior.

18f3a07b20 backends/rng-random: Get rid of qemu_open_old()
For qemu_open_old(), osdep.h said:

> Don't introduce new usage of this function, prefer the following
> qemu_open/qemu_create that take an "Error **errp".

3c5f6114d9 qapi: remove "Example" doc section
Fully eliminate the "Example" sections in QAPI doc blocks now that they
have all been converted to arbitrary rST syntax using the
".. qmp-example::" directive. Update tests to match.

Migrating to the new syntax
---------------------------

The old "Example:" or "Examples:" section syntax is now caught as an
error, but "Example::" is stil permitted as explicit rST syntax for an
un-lexed, generic preformatted text block.

('Example' is not special in this case, any sentence that ends with "::"
will start an indented code block in rST.)

Arbitrary rST for Examples is now possible, but it's strongly
recommended that documentation authors use the ".. qmp-example::"
directive for consistent visual formatting in rendered HTML docs. The
":title:" directive option may be used to add extra information into the
title bar for the example. The ":annotated:" option can be used to write
arbitrary rST instead, with nested "::" blocks applying QMP formatting
where desired.

Other choices available are ".. code-block:: QMP" which will not create
an "Example:" box, or the short-form "::" code-block syntax which will
not apply QMP highlighting when used outside of the qmp-example
directive.

Why?
----

This patch has several benefits:

1. Example sections can now be written more arbitrarily, mixing
   explanatory paragraphs and code blocks however desired.

2. Example sections can now use fully arbitrary rST.

3. All code blocks are now lexed and validated as QMP; increasing
   usability of the docs and ensuring validity of example snippets.

   (To some extent - This patch only gaurantees it lexes correctly, not
   that it's valid under the JSON or QMP grammars. It will catch most
   small mistakes, however.)

4. Each qmp-example can be titled or annotated independently without
   bypassing the QMP lexer/validator.

   (i.e. code blocks are now for *code* only, so we don't have to
   sacrifice exposition for having lexically valid examples.)

NOTE: As with the "Notes" conversion (d461c27973), this patch (and the
      three preceding) may change the rendering order for Examples in
      the current generator. The forthcoming qapidoc rewrite will fix
      this by always generating documentation in source order.

6f07c59fb1 qapi: convert "Example" sections with longer prose
These examples require longer explanations or have explanations that
require markup to look reasonable when rendered and so use the longer
form of the ".. qmp-example::" directive.

By using the :annotated: option, the content in the example block is
assumed *not* to be a code block literal and is instead parsed as normal
rST - with the exception that any code literal blocks after `::` will
assumed to be a QMP code literal block.

Note: There's one title-less conversion in this patch that comes along
for the ride because it's part of a larger "Examples" block that was
better to convert all at once.

See commit-5: "docs/qapidoc: create qmp-example directive", for a
              detailed explanation of this custom directive syntax.

See commit+1: "qapi: remove "Example" doc section" for a detailed

a9eab6e2e6 qapi: convert "Example" sections with titles
When an Example section has a brief explanation, convert it to a
qmp-example:: section using the :title: option.

Rule of thumb: If the title can fit on a single line and requires no rST
markup, it's a good candidate for using the :title: option of
qmp-example.

In this patch, trailing punctuation is removed from the title section
for consistent headline aesthetics. In just one case, specifics of the
example are removed to make the title read better.

See commit-4: "docs/qapidoc: create qmp-example directive", for a
              detailed explanation of this custom directive syntax.

that in a few cases, example sections are split into two or more
separate example blocks. This is only done stylistically to create a
delineation between two or more logically independent examples.

76e375fc3c docs/qapidoc: add QMP highlighting to annotated qmp-example blocks
For any code literal blocks inside of a qmp-example directive, apply and
enforce the QMP lexer/highlighter to those blocks.

This way, you won't need to write:

```
.. qmp-example::
   :annotated:

   Blah blah

   .. code-block:: QMP

      -> { "lorem": "ipsum" }
```

But instead, simply:

```
.. qmp-example::
   :annotated:

   Blah blah::

     -> { "lorem": "ipsum" }
```

Once the directive block is exited, whatever the previous default
highlight language was will be restored; localizing the forced QMP
lexing to exclusively this directive.

Note, if the default language is *already* QMP, this directive will not
generate and restore redundant highlight configuration nodes. We may
well decide that the default language ought to be QMP for any QAPI
reference pages, but this way the directive behaves consistently no
matter where it is used.

547864f9d4 docs/qapidoc: create qmp-example directive
This is a directive that creates a syntactic sugar for creating
"Example" boxes very similar to the ones already used in the bitmaps.rst
document, please see e.g.
https://www.qemu.org/docs/master/interop/bitmaps.html#creation-block-dirty-bitmap-add

In its simplest form, when a custom title is not needed or wanted, and
the example body is *solely* a QMP example:

```
.. qmp-example::

   {body}
```

is syntactic sugar for:

```
.. admonition:: Example:

   .. code-block:: QMP

      {body}
```

When a custom, plaintext title that describes the example is desired,
this form:

```
.. qmp-example::
   :title: Defrobnification

   {body}
```

Is syntactic sugar for:

```
.. admonition:: Example: Defrobnification

   .. code-block:: QMP

      {body}
```

Lastly, when Examples are multi-step processes that require non-QMP
exposition, have lengthy titles, or otherwise involve prose with rST
markup (lists, cross-references, etc), the most complex form:

```
.. qmp-example::
   :annotated:

   This example shows how to use `foo-command`::

     {body}

   For more information, please see `frobnozz`.
```

Is desugared to:

```
.. admonition:: Example:

   This example shows how to use `foo-command`::

     {body}

   For more information, please see `frobnozz`.
```

Note that :annotated: and :title: options can be combined together, if
desired.

The primary benefit here being documentation source consistently using
the same directive for all forms of examples to ensure consistent visual
styling, and ensuring all relevant prose is visually grouped alongside
the code literal block.

Note that as of this commit, the code-block rST syntax "::" does not
apply QMP highlighting; you would need to use ".. code-block:: QMP". The
very next commit changes this behavior to assume all "::" code blocks
within this directive are QMP blocks.
