84f82ddcbb Deprecate KVM support for AArch32
The Linux kernel has dropped support for allowing 32-bit Arm systems
to host KVM guests (kernel commit 541ad0150ca4aa663a2, which just
landed upstream in the 5.7 merge window).  Mark QEMU's support for
this configuration as deprecated, so that we can delete that support
code in 5.2.

e5910d42dd docs: Improve our gdbstub documentation
The documentation of our -s and -gdb options is quite old; in
particular it still claims that it will cause QEMU to stop and wait
for the gdb connection, when this has not been true for some time:
you also need to pass -S if you want to make QEMU not launch the
guest on startup.

Improve the documentation to mention this requirement in the
executable's --help output, the documentation of the -gdb option in
the manual, and in the "GDB usage" chapter.

Includes some minor tweaks to these paragraphs of documentation
since I was editing them anyway (such as dropping the description
of our gdb support as "primitive").

22062e54bb ppc: Officially deprecate the CPU "compat" property
Server class POWER CPUs have a "compat" property, which was obsoleted
by commit 7843c0d60d and replaced by a "max-cpu-compat" property on the
pseries machine type. A hack was introduced so that passing "compat" to
-cpu would still produce the desired effect, for the sake of backward
compatibility : it strips the "compat" option from the CPU properties
and applies internally it to the pseries machine. The accessors of the
"compat" property were updated to do nothing but warn the user about the
deprecated status when doing something like:

$ qemu-system-ppc64 -global POWER9-family-powerpc64-cpu.compat=power9
qemu-system-ppc64: warning: CPU 'compat' property is deprecated and has no
 effect; use max-cpu-compat machine property instead

This was merged during the QEMU 2.10 timeframe, a few weeks before we
formalized our deprecation process. As a consequence, the "compat"
property fell through the cracks and was never listed in the officialy
deprecated features.

We are now eight QEMU versions later, it is largely time to mention it
in qemu-deprecated.texi. Also, since -global XXX-powerpc64-cpu.compat=
has been emitting warnings since QEMU 2.10 and the usual way of setting
CPU properties is with -cpu, completely remove the "compat" property.
Keep the hack so that -cpu XXX,compat= stays functional some more time,
as required by our deprecation process.

The now empty powerpc_servercpu_properties[] list which was introduced
for "compat" and never had any other use is removed on the way. We can
re-add it in the future if the need for a server class POWER CPU specific
property arises again.

3b2c52c017 qemu-cpu-models.rst: Document -noTSX, mds-no, taa-no, and tsx-ctrl
- Add the '-noTSX' variants for CascadeLake and SkyLake.

- Document the three MSR bits: 'mds-no', 'taa-no', and 'tsx-ctrl'

  Two confusing things about 'mds-no' (and the first point applies to
  the other two MSRs too):

  (1) The 'mds-no' bit will _not_ show up in the guest's /proc/cpuinfo.
      Rather it is used to fill in the guest's sysfs:

        /sys/devices/system/cpu/vulnerabilities/mds:Not affected

      Paolo confirmed on IRC as such.

  (2) There are _three_ variants[+] of CascadeLake CPUs, with different
      stepping levels: 5, 6, and 7.  To quote wikichip.org[*]:

        "note that while steppings 6 & 7 are fully mitigated, earlier
        stepping 5 is not protected against MSBDS, MLPDS, nor MDSUM"

      The above is also indicated in the Intel's document[+], as
      indicated by "No" under the three columns of MFBDS, MSBDS, and
      MLPDS.

  I've expressed this in the docs without belabouring the details.

6fe6d6c9a9 docs: Be consistent about capitalization of 'Arm'
The company 'Arm' went through a rebranding some years back
involving a recapitalization from 'ARM' to 'Arm'. As a result
our documentation is a bit inconsistent between the two forms.
It's not worth trying to update everywhere in QEMU, but it's
easy enough to make docs/ consistent.

Note that "ARMv8" and similar architecture names, and
older CPU names like "ARM926" still retain all-caps.

c11a8e890c docs/system: Split target-arm.rst into sub-documents
Currently the documentation for Arm system emulator targets is in a
single target-arm.rst.  This describes only some of the boards and
often in a fairly abbreviated fashion. Restructure it so that each
board has its own documentation file in the docs/system/arm/
subdirectory.

This will hopefully encourage us to write board documentation that
describes the board in detail, rather than a few brief paragraphs
in a single long page. The table of contents should also help users
to find the board they care about faster.

Once the structure is in place we'll be able to move microvm.rst
from the top-level docs/ directory.

All the text from the old page is retained, except for the final
paragraph ("A Linux 2.6 test image is available on the QEMU web site.
More information is available in the QEMU mailing-list archive."),
which is deleted. The git history shows this was originally added
in reference to the integratorcp board (at that time the only
Arm board that was supported), and has subsequently gradually been
further and further separated from the integratorcp documentation
by the insertion of other board documentation sections. It's
extremely out of date and no longer accurate, since AFAICT there
isn't an integratorcp kernel on the website any more; so better
deleted than retained.

5f07c4d60d qapi: Flatten object-add
Mapping object-add to the command line as is doesn't result in nice
syntax because of the nesting introduced with 'props'. This becomes
nicer and more consistent with device_add and netdev_add when we accept
properties for the object on the top level instead.

'props' is still accepted after this patch, but marked as deprecated.

bf87bef091 docs: Split out sections for the manpage into .rst.inc files
Sphinx doesn't have very good facilities for marking chunks
of documentation as "put this in the manpage only". So instead
we move the parts we want to put into both the HTML manuals
and the manpage into their own .rst.inc files, which we can
include from both the main manual rst files and a new toplevel
rst file that will be the skeleton of the qemu.1 manpage.

In this commit, just split out the parts of the documentation
that go in the manpage.

09ce5f2d6b qemu-options.hx: Fix up the autogenerated rST
This commit contains hand-written fixes for some issues with the
autogenerated rST fragments in qemu-options.hx:

 * Sphinx complains about the UTF-8 art table in the documentation of
   the -drive option.  Replace it with a proper rST format table.

 * rST does not like definition list entries with no actual
   definition, but it is possible to work around this by putting a
   single escaped literal space as the definition line.

 * The "-g widthxheight" option documentation suffers particularly
   badly from losing the distinction between italics and fixed-width
   as a result of the auto conversion, so put it back in again.

 * The script missed some places that use the |qemu_system| etc
   macros and need to be marked up as parsed-literal blocks.

 * The script autogenerated an expanded out version of the
   contents of qemu-option-trace.texi; replace it with an
   qemu-option-trace.rst.inc include.

This is sufficient that we can enable inclusion of the
option documentation from invocation.rst.

196afbb094 docs: Roll -prom-env and -g target-specific info into qemu-options.hx
The SPARC and PPC targets currently have a fragment of target-specific
information about the -g and -prom options which would be better placed
as part of the general documentation of those options in qemu-options.hx.
Move the relevant information to those locations.

SPARC also has a bit of text about the -M option which is out of
date and provides no useful information over the generic documentation
of that option, so just delete it.

The motivation here is again to avoid having to awkwardly include
this text into the rST version of the qemu.1 manpage.

44d79a6bd7 docs: Roll semihosting option information into qemu-options.hx
Currently the per-target documentation for those targets that
implement semihosting includes a bit of text that goes into both the

text is redundant with the earlier generic option description of the
semihosting option produced from qemu-options.hx. To avoid having
to create a lot of stub include files to include into the rST
generated qemu.1 manpage, roll target-specific bits of information
into the qemu-options.hx text, so the user doesn't have to look
in two places for this information.

In addition, the following changes were made manually:

- target-i386.rst and target-mips.rst: replace CPU model documentation with
  an include directive

- monitor.rst: replace the command section with a comment

- images.rst: add toctree

- target-arm.rst: Replace use of :math: (which Sphinx complains
  about) with :sup:, and hide it behind |I2C| and |I2C| substitutions.

1bf84a1e2e docs/system: Convert qemu-cpu-models.texi to rST
This doc was originally written by Daniel P. Berrangé
<berrange@redhat.com>, introduced via commit[1]: 2544e9e4aa (docs: add
guidance on configuring CPU models for x86, 2018-06-27).

In this patch:

  - 1-1 conversion of Texinfo to rST, besides a couple of minor
    tweaks that are too trivial to mention.   (Thanks to Stephen
    Finucane on IRC for the suggestion to use rST "definition lists"
    instead of bullets in some places.)

    Further modifications will be done via a separate patch.

  - rST and related infra changes: manual page generation, Makefile
    fixes, clean up references to qemu-cpu-models.texi, update year in
    the copyright notice, etc.

[1] https://git.qemu.org/?p=qemu.git;a=commit;h=2544e9e4aa

As part of the conversion, we use a more generic 'author' attribution
for the manpage than we previously had, as agreed with the original
author Dan Berrange.

Rather than accumulating generally useful rST substitution
definitions in individual rST files, create a defs.rst.inc where we

from qemu-block-drivers.rst.

Add a comment noting a pitfall where putting literal markup in the
definition of |qemu_system| makes it misrender manpage output; this
means the point-of-use must handle the literal markup (which is
almost always done by having it inside a parsed-literal block).

to the user as:
 * a qemu-block-drivers manpage
 * a section of the main qemu-doc HTML documentation

Convert the documentation to rST format, and present it to
the user as:
 * a qemu-block-drivers manpage
 * part of the system/ Sphinx manual

This follows the same pattern we've done for qemu-ga and qemu-nbd.

We have to drop a cross-reference from the documentation of the
-cdrom option back to the qemu-block-drivers documentation, since
they're no longer within the same texinfo document.

As noted in a comment, the manpage output is slightly compromised
due to limitations in Sphinx. In an ideal world, the HTML output
would have the various headings like 'Disk image file formats'
as top-level section headings (which then appear in the overall
system manual's table-of-contents), and it would not have the
section headings which make sense only for the manpage like
'synopsis', 'description', and 'see also'. Unfortunately, the
mechanism Sphinx provides for restricting pieces of documentation
is limited to the point of being flawed: the 'only::' directive
is implemented as a filter that is applied at a very late stage
in the document processing pipeline, rather than as an early
equivalent of an #ifdef. This means that Sphinx's process of
identifying which section heading markup styles are which levels
of heading gets confused if the 'only::' directive contains
section headings which would affect the heading-level of a
later heading. I have opted to prioritise making the HTML format
look better, with the compromise being that in the manpage
the 'Disk image file formats' &c headings are top-level headings
rather than being sub-headings under the traditional 'Description'
top-level section title.
