dd23f9ec51 docs: remove Sphinx 1.x compatibility code
In general, the Use_SSI workaround is no longer needed, and neither is
the pre-1.6 logging shim for kerneldoc.

fe791b7fcc Python: bump minimum sphinx version to 3.4.3
With RHEL 8 support retired (It's been two years since RHEL9 released),
our very oldest build platform version of Sphinx is now 3.4.3; and
keeping backwards compatibility for versions as old as v1.6 when using
domain extensions is a lot of work we don't need to do.

This patch is motivated by my work creating a new QAPI domain, which
unlike the dbus documentation, cannot be allowed to regress by creating
a "dummy" doc when operating under older sphinx versions. Easier is to
raise our minimum version as far as we can push it forwards, reducing my
burden in creating cross-compatibility hacks and patches.

CentOS Stream 9: v3.4.3
OpenSUSE Leap 15.4: EOL
OpenSUSE Leap 15.5: 2.3.1, 4.2.0 and 7.2.6

RHEL9 / CentOS Stream 9 becomes the new defining factor in staying at
Sphinx 3.4.3 due to downstream offline build requirements that force us
to use platform Sphinx instead of newer packages from PyPI.

e389929d19 sphinx/qapidoc: Fix to generate doc for explicit, unboxed arguments
When a command's arguments are specified as an explicit type T,
generated documentation points to the members of T.

Example:

    ##
    # @announce-self:
    #
    # Trigger generation of broadcast RARP frames to update network
    [...]
    ##
    { 'command': 'announce-self', 'boxed': true,
      'data' : 'AnnounceParameters'}

generates

    "announce-self" (Command)
    -------------------------

    Trigger generation of broadcast RARP frames to update network
    [...]

    Arguments
    ~~~~~~~~~

    The members of "AnnounceParameters"

Except when the command takes its arguments unboxed , i.e. it doesn't
have 'boxed': true, we generate *nothing*.  A few commands have a
reference in their doc comment to compensate, but most don't.

Example:

    ##
    # @blockdev-snapshot-sync:
    #
    # Takes a synchronous snapshot of a block device.
    #
    # For the arguments, see the documentation of BlockdevSnapshotSync.
    [...]
    ##
    { 'command': 'blockdev-snapshot-sync',
      'data': 'BlockdevSnapshotSync',
      'allow-preconfig': true }

generates

    "blockdev-snapshot-sync" (Command)
    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    Takes a synchronous snapshot of a block device.

    For the arguments, see the documentation of BlockdevSnapshotSync.
    [...]

Same for event data.

Fix qapidoc.py to generate the reference regardless of boxing.  Delete
now redundant references in the doc comments.

d461c27973 qapi: convert "Note" sections to plain rST
We do not need a dedicated section for notes. By eliminating a specially
parsed section, these notes can be treated as normal rST paragraphs in
the new QMP reference manual, and can be placed and styled much more
flexibly.

Convert all existing "Note" and "Notes" sections to pure rST. As part of
the conversion, capitalize the first letter of each sentence and add
trailing punctuation where appropriate to ensure notes look sensible and
consistent in rendered HTML documentation. Markup is also re-aligned to
the de-facto standard of 3 spaces for directives.

Update docs/devel/qapi-code-gen.rst to reflect the new paradigm, and
update the QAPI parser to prohibit "Note" sections while suggesting a
new syntax. The exact formatting to use is a matter of taste, but a good
candidate is simply:

.. note:: lorem ipsum ...
   ... dolor sit amet ...
   ... consectetur adipiscing elit ...

... but there are other choices, too. The Sphinx readthedocs theme
offers theming for the following forms (capitalization unimportant); all
are adorned with a (!) symbol () in the title bar for rendered HTML
docs.

See
https://sphinx-rtd-theme.readthedocs.io/en/stable/demo/demo.html#admonitions
for examples of each directive/admonition in use.

These are rendered in orange:

.. Attention:: ...
.. Caution:: ...
.. WARNING:: ...

These are rendered in red:

.. DANGER:: ...
.. Error:: ...

These are rendered in green:

.. Hint:: ...
.. Important:: ...
.. Tip:: ...

These are rendered in blue:

.. Note:: ...
.. admonition:: custom title

   admonition body text

This patch uses ".. note::" almost everywhere, with just two "caution"
directives. Several instances of "Notes:" have been converted to
merely ".. note::", or multiple ".. note::" where appropriate.
".. admonition:: notes" is used in a few places where we had an
ordered list of multiple notes that would not make sense as
standalone/separate admonitions.  Two "Note:" following "Example:"
have been turned into ordinary paragraphs within the example.

NOTE: Because qapidoc.py does not attempt to preserve source ordering of
sections, the conversion of Notes from a "tagged section" to an
"untagged section" means that rendering order for some notes *may
change* as a result of this patch. The forthcoming qapidoc.py rewrite
strictly preserves source ordering in the rendered documentation, so
this issue will be rectified in the new generator.

2664f3176a docs/qapidoc: fix nested parsing under untagged sections
Sphinx does not like sections without titles, because it wants to
convert every section into a reference. When there is no title, it
struggles to do this and transforms the tree inproperly.

Depending on the rST used, this may result in an assertion error deep in
the docutils HTMLWriter.

(Observed when using ".. admonition:: Notes" under such a section - When
this is transformed with its own <title> element, Sphinx is fooled into
believing this title belongs to the section and incorrect mutates the
docutils tree, leading to errors during rendering time.)

When parsing an untagged section (free paragraphs), skip making a hollow
section and instead append the parse results to the prior section.

Many Bothans died to bring us this information.

The resulting output changes are basically invisible.

939c639e1d qapi/parser: preserve indentation in QAPIDoc sections
Change get_doc_indented() to preserve indentation on all subsequent text
lines, and create a compatibility dedent() function for qapidoc.py that
removes indentation the same way get_doc_indented() did.

This is being done for the benefit of a new qapidoc generator which
requires that indentation in argument and features sections are
preserved.

Prior to this patch, a section like this:

```
@name: lorem ipsum
   dolor sit amet
     consectetur adipiscing elit
```

would have its body text be parsed into:

```
lorem ipsum
dolor sit amet
  consectetur adipiscing elit
```

We want to preserve the indentation for even the first body line so that
the entire block can be parsed directly as rST. This patch would now
parse that segment into:

```
lorem ipsum
   dolor sit amet
     consectetur adipiscing elit
```

This is helpful for formatting arguments and features as field lists in
rST, where the new generator will format this information as:

```
:arg type name: lorem ipsum
   dolor sit amet
     consectetur apidiscing elit
```

...and can be formed by the simple concatenation of the field list
construct and the body text. The indents help preserve the continuation
of a block-level element, and further allow the use of additional rST
block-level constructs such as code blocks, lists, and other such
markup.

This understandably breaks the existing qapidoc.py; so a new function is
added there to dedent the text for compatibility. Once the new generator
is merged, this function will not be needed any longer and can be
dropped.

I verified this patch changes absolutely nothing by comparing the
md5sums of the QMP ref html pages both before and after the change, so
it's certified inert. QAPI test output has been updated to reflect the
new strategy of preserving indents for rST.

36c6dcc266 docs/qapidoc: delint a tiny portion of the module
In a forthcoming series that adds a new QMP documentation generator, it
will be helpful to have a linting baseline. However, there's no need to
shuffle around the deck chairs too much, because most of this code will
be removed once that new qapidoc generator (the "transmogrifier") is in
place.

To ease my pain: just turn off the black auto-formatter for most, but
not all, of qapidoc.py. This will help ensure that *new* code follows a
coding standard without bothering too much with cleaning up the existing
code.

Code that I intend to keep is still subject to the delinting beam.

4e647fa085 hostmem: add a new memory backend based on POSIX shm_open()
shm_open() creates and opens a new POSIX shared memory object.
A POSIX shared memory object allows creating memory backend with an
associated file descriptor that can be shared with external processes
(e.g. vhost-user).

The new `memory-backend-shm` can be used as an alternative when
`memory-backend-memfd` is not available (Linux only), since shm_open()
should be provided by any POSIX-compliant operating system.

This backend mimics memfd, allocating memory that is practically
anonymous. In theory shm_open() requires a name, but this is allocated
for a short time interval and shm_unlink() is called right after
shm_open(). After that, only fd is shared with external processes
(e.g., vhost-user) as if it were associated with anonymous memory.

In the future we may also allow the user to specify the name to be
passed to shm_open(), but for now we keep the backend simple, mimicking
anonymous memory such as memfd.

4408155ac5 meson: Drop the .fa library suffix
The non-standard .fa library suffix breaks the link source
de-duplication done by Meson so drop it.

The lack of link source de-duplication causes AddressSanitizer to
complain ODR violations, and makes GNU ld abort when combined with
clang's LTO.

Fortunately, the non-standard suffix is not necessary anymore for
two reasons.

First, the non-standard suffix was necessary for fork-fuzzing.
Meson wraps all standard-suffixed libraries with --start-group and
--end-group. This made a fork-fuzz.ld linker script wrapped as well and
broke builds. Commit d2e6f9272d ("fuzz: remove fork-fuzzing
scaffolding") dropped fork-fuzzing so we can now restore the standard
suffix.

Second, the libraries are not even built anymore, because it is
possible to just use the object files directly via extract_all_objects().

The occurences of the suffix were detected and removed by performing
a tree-wide search with 'fa' and .fa (note the quotes and dot).

414b180d42 meson: Pass objects and dependencies to declare_dependency()
We used to request declare_dependency() to link_whole static libraries.
If a static library is a thin archive, GNU ld keeps all object files
referenced by the archive open, and sometimes exceeds the open file limit.

Another problem with link_whole is that suboptimal handling of nested
dependencies.

link_whole by itself does not propagate dependencies. In particular,
gnutls, a dependency of crypto, is not propagated to its users, and we
currently workaround the issue by declaring gnutls as a dependency for
each crypto user.  On the other hand, if you write something like

  libfoo = static_library('foo', 'foo.c', dependencies: gnutls)
  foo = declare_dependency(link_whole: libfoo)

  libbar = static_library('bar', 'bar.c', dependencies: foo)
  bar = declare_dependency(link_whole: libbar, dependencies: foo)
  executable('prog', sources: files('prog.c'), dependencies: [foo, bar])

hoping to propagate the gnutls dependency into bar.c, you'll see a
linking failure for "prog", because the foo.c.o object file is included in
libbar.a and therefore it is linked twice into "prog": once from libfoo.a
and once from libbar.a.  Here Meson does not see the duplication, it
just asks the linker to link all of libfoo.a and libbar.a into "prog".

Instead of using link_whole, extract objects included in static libraries
and pass them to declare_dependency(); and then the dependencies can be
added as well so that they are propagated, because object files on the
linker command line are always deduplicated.

This requires Meson 1.1.0 or later.

e7100972f2 hw/arm/virt: allow creation of a second NonSecure UART
For some use-cases, it is helpful to have more than one UART
available to the guest.  If the second UART slot is not already used
for a TrustZone Secure-World-only UART, create it as a NonSecure UART
only when the user provides a serial backend (e.g.  via a second
-serial command line option).

This avoids problems where existing guest software only expects a
single UART, and gets confused by the second UART in the DTB.  The
major example of this is older EDK2 firmware, which will send the
GRUB bootloader output to UART1 and the guest serial output to UART0.
Users who want to use both UARTs with a guest setup including EDK2
are advised to update to EDK2 release edk2-stable202311 or newer.
(The prebuilt EDK2 blobs QEMU upstream provides are new enough.)
The relevant EDK2 changes are the ones described here:

8d60280e4f migration: Add documentation for fdset with multifd + file
With the last few changes to the fdset infrastructure, we now allow
multifd to use an fdset when migrating to a file. This is useful for
the scenario where the management layer wants to have control over the
migration file.

By receiving the file descriptors directly, QEMU can delegate some
high level operating system operations to the management layer (such
as mandatory access control). The management layer might also want to
add its own headers before the migration stream.

Document the "file:/dev/fdset/#" syntax for the multifd migration with
mapped-ram. The requirements for the fdset mechanism are:

- the fdset must contain two fds that are not duplicates between
  themselves;

- if direct-io is to be used, exactly one of the fds must have the
  O_DIRECT flag set;

- the file must be opened with WRONLY on the migration source side;

- the file must be opened with RDONLY on the migration destination
  side.

1f97715c83 Revert "python: use vendored tomli"
Now that Ubuntu 20.04 is not included anymore, there is no need to ship
it as part of QEMU; Ubuntu 22.04 includes it and Leap users anyway
need to install all the required dependencies from PyPI.

This mostly reverts commit ec77ee7634de123b7c899739711000fd21dab68b,
with just some changes to the wording.

888788dd76 docs: i386: pc: Avoid mentioning limit of maximum vCPUs
Different versions of PC machine support different maximum vCPUs, and
even different features have limits on the maximum number of vCPUs (
For example, if x2apic is not enabled in the TCG case, the maximum of
255 vCPUs are supported).

It is difficult to list the maximum vCPUs under all restrictions. Thus,
to avoid confusion, avoid mentioning specific maximum vCPU number
limitations here.

cc1d2e04d5 docs/devel: update references to centos to non-versioned container
>From the website:

"After May 31, 2024, CentOS Stream 8 will be archived and no further
updates will be provided."

We have updated a few bits but there are still references that need
fixing. Rather than bump I've replaced them with references to the
Debian image so we don't have to bump at the next update.

This broke since eef0bae3a7 (migration: Remove block migration) but
even after that was addressed it still fails to complete. As it will
shortly be EOL lets to remove the runner definition and the related
ansible setup bits.

We still have centos9 docker images build and test.

7b34df4426 i386/sev: Introduce 'sev-snp-guest' object
SEV-SNP support relies on a different set of properties/state than the
existing 'sev-guest' object. This patch introduces the 'sev-snp-guest'
object, which can be used to configure an SEV-SNP guest. For example,
a default-configured SEV-SNP guest with no additional information
passed in for use with attestation:

  -object sev-snp-guest,id=sev0

or a fully-specified SEV-SNP guest where all spec-defined binary
blobs are passed in as base64-encoded strings:

  -object sev-snp-guest,id=sev0, \
    policy=0x30000, \
    init-flags=0, \
    id-block=YWFhYWFhYWFhYWFhYWFhCg==, \
    id-auth=CxHK/OKLkXGn/KpAC7Wl1FSiisWDbGTEKz..., \
    author-key-enabled=on, \
    host-data=LNkCWBRC5CcdGXirbNUV1OrsR28s..., \
    guest-visible-workarounds=AA==, \

See the QAPI schema updates included in this patch for more usage
details.

In some cases these blobs may be up to 4096 characters, but this is
generally well below the default limit for linux hosts where
command-line sizes are defined by the sysconf-configurable ARG_MAX
value, which defaults to 2097152 characters for Ubuntu hosts, for
example.

a271b8d7b2 virtio-blk: remove SCSI passthrough functionality
The legacy SCSI passthrough functionality has never been enabled for
VIRTIO 1.0 and was deprecated more than four years ago.

Get rid of it---almost, because QEMU is advertising it unconditionally
for legacy virtio-blk devices.  Just parse the header and return a
nonzero status.
