f169413c27 hw/mips: Remove the 'r4k' machine
We deprecated the support for the 'r4k' machine for the 5.0 release
(commit d32dc61421), which means that our deprecation policy allows
us to drop it in release 5.2. Remove the code.

To repeat the rationale from the deprecation note:
- this virtual machine has no specification
- the Linux kernel dropped support for it 10 years ago

Users are recommended to use the Malta board instead.

cbad81cef8 nbd: Update qapi to support exporting multiple bitmaps
Since 'block-export-add' is new to 5.2, we can still tweak the
interface; there, allowing 'bitmaps':['str'] is nicer than
'bitmap':'str'.  This wires up the qapi and qemu-nbd changes to permit
passing multiple bitmaps as distinct metadata contexts that the NBD
client may request, but the actual support for more than one will
require a further patch to the server.

Note that there are no changes made to the existing deprecated
'nbd-server-add' command; this required splitting the QAPI type
BlockExportOptionsNbd, which fortunately does not affect QMP
introspection.

526dbbe087 hw/gpio: Add GPIO model for Nuvoton NPCM7xx
The NPCM7xx chips have multiple GPIO controllers that are mostly
identical except for some minor differences like the reset values of
some registers. Each controller controls up to 32 pins.

Each individual pin is modeled as a pair of unnamed GPIOs -- one for
emitting the actual pin state, and one for driving the pin externally.
Like the nRF51 GPIO controller, a gpio level may be negative, which
means the pin is not driven, or floating.

e23e7b1259 hw/arm/npcm7xx: Add EHCI and OHCI controllers
The NPCM730 and NPCM750 chips have a single USB host port shared between
a USB 2.0 EHCI host controller and a USB 1.1 OHCI host controller. This
adds support for both of them.

Testing notes:
  * With -device usb-kbd, qemu will automatically insert a full-speed
    hub, and the keyboard becomes controlled by the OHCI controller.
  * With -device usb-kbd,bus=usb-bus.0,port=1, the keyboard is directly
    attached to the port without any hubs, and the device becomes
    controlled by the EHCI controller since it's high speed capable.
  * With -device usb-kbd,bus=usb-bus.0,port=1,usb_version=1, the
    keyboard is directly attached to the port, but it only advertises
    itself as full-speed capable, so it becomes controlled by the OHCI
    controller.

In all cases, the keyboard device enumerates correctly.

326ccfe240 hw/misc: Add npcm7xx random number generator
The RNG module returns a byte of randomness when the Data Valid bit is
set.

This implementation ignores the prescaler setting, and loads a new value
into RNGD every time RNGCS is read while the RNG is enabled and random
data is available.

A qtest featuring some simple randomness tests is included.

7239c050e8 Remove deprecated -no-kvm option
The option has never been mentioned in our documentation, it's been
deprecated since years, it's marked with QEMU_ARCH_I386 (which does
not make sense anymore since KVM is available on other architectures,
too), it does not do anything by default in upstream QEMU (since TCG
is the default here anyway), and we're spending too much precious time
each year discussing whether it makes sense to keep this option as a
nice suger or not... let's finally put an end on this and remove it.

e1c4269763 block: deprecate the sheepdog block driver
This thread from a little over a year ago:

  http://lists.wpkg.org/pipermail/sheepdog/2019-March/thread.html

states that sheepdog is no longer actively developed. The only mentioned
users are some companies who are said to have it for legacy reasons with
plans to replace it by Ceph. There is talk about cutting out existing
features to turn it into a simple demo of how to write a distributed
block service. There is no evidence of anyone working on that idea:

  https://github.com/sheepdog/sheepdog/commits/master

No real commits to git since Jan 2018, and before then just some minor
technical debt cleanup.

There is essentially no activity on the mailing list aside from
patches to QEMU that get CC'd due to our MAINTAINERS entry.

Fedora packages for sheepdog failed to build from upstream source
because of the more strict linker that no longer merges duplicate
global symbols. Fedora patches it to add the missing "extern"
annotations and presumably other distros do to, but upstream source
remains broken.

There is only basic compile testing, no functional testing of the
driver.

Since there are no build pre-requisites the sheepdog driver is currently
enabled unconditionally. This would result in configure issuing a
deprecation warning by default for all users. Thus the configure default
is changed to disable it, requiring users to pass --enable-sheepdog to
build the driver.

4258c8e221 docs/system/deprecated: Mark the 'moxie' CPU as deprecated
It is currently unclear whether anybody is still using the 'moxie' CPU,
and there are no images for testing available this CPU, so the code has
likely bit-rotten in the course of time. When I asked the maintainer
for information, I did not get a reply within four weeks yet (see
https://lists.gnu.org/archive/html/qemu-devel/2020-08/msg07201.html).
The last Signed-off-by line from Anthony in our repo is from 2013,
so it seems like this code is rather unmaintained. Time to put it onto
the deprecation list to see whether somebody is still interested in this
code or whether we could remove it in a couple of releases.

ef1f5b0a96 docs/system: clarify deprecation schedule
The sentence explaining the deprecation schedule is ambiguous. Make it
clear that a feature deprecated in the Nth release is guaranteed to
remain available in the N+1th release. Removal can occur in the N+2nd
release or later.

As an example of this in action, see commit
25956af3fe ("block: Finish deprecation of
'qemu-img convert -n -o'"). The feature was deprecated in QEMU 4.2.0. It
was present in the 5.0.0 release and removed in the 5.1.0 release.

353a06b425 manual: escape backslashes in "parsed-literal" blocks
According to
<https://docutils.sourceforge.io/docs/ref/rst/directives.html#parsed-literal>,
"inline markup is recognized and there is no protection from parsing.
Backslash-escapes may be necessary to prevent unintended parsing".

The qemu(1) manual page (formatted with Sphinx 2.2.2) has several overlong
lines on my system. A stand-alone backslash at EOL serves as line
continuation in a "parsed-literal" block. Therefore, escape the
backslashes that we want to appear as such in the formatted documentation.

d849800512 Deprecate lm32 port
Deprecate our lm32 target support. Michael Walle (former lm32 maintainer)
suggested that we do this in 2019:
 https://www.mail-archive.com/qemu-devel@nongnu.org/msg605024.html
because the only public user of the architecture is the many-years-dead
milkymist project. (The Linux port to lm32 was never merged upstream.)

In commit 4b4d96c776 (March 2020) we marked it as 'orphan' in
the MAINTAINERS file, but didn't officially deprecate it. Mark it
deprecated now, with the intention of removing it from QEMU in
mid-2021 before the 6.1 release.

   05119217a9bd199c for its 5.9 release (with rationale in the
   cover letter: https://lkml.org/lkml/2020/8/3/232 )
 * there is apparently no upstream toolchain that can create unicore32
   binaries
 * the maintainer doesn't seem to have made any contributions to
   QEMU since the port first landed in 2012
 * nobody else seems to have made changes to the unicore code except
   for generic cleanups either

 * PSRAM is at 0x6000_0000
 * Ethernet is at 0xa000_0000

82bf7ae84c target/arm: Remove KVM support for 32-bit Arm hosts
We deprecated the support for KVM on 32-bit Arm hosts in time
for release 5.0, which means that our deprecation policy allows
us to drop it in release 5.2. Remove the code.

To repeat the rationale from the deprecation note: the Linux
kernel dropped support for 32-bit Arm KVM hosts in 5.7.

Running 32-bit guests on a 64-bit Arm host remains supported.

d9f059aa6c qemu-img: Deprecate use of -b without -F
Creating an image that requires format probing of the backing image is
potentially unsafe (we've had several CVEs over the years based on
probes leaking information to the guest on a subsequent boot, although
these days tools like libvirt are aware of the issue enough to prevent
the worst effects).  For example, if our probing algorithm ever
changes, or if other tools like libvirt determine a different probe
result than we do, then subsequent use of that backing file under a
different format will present corrupted data to the guest.
Fortunately, the worst effects occur only when the backing image is
originally raw, and we at least prevent commit into a probed raw
backing file that would change its probed type.

Still, it is worth starting a deprecation clock so that future
qemu-img can refuse to create backing chains that would rely on
probing, to encourage clients to avoid unsafe practices.  Most
warnings are intentionally emitted from bdrv_img_create() in the block
layer, but qemu-img convert uses bdrv_create() which cannot emit its
own warning without causing spurious warnings on other code paths.  In
the end, all command-line image creation or backing file rewriting now
performs a check.

Furthermore, if we probe a backing file as non-raw, then it is safe to
explicitly record that result (rather than relying on future probes);
only where we probe a raw image do we care about further warnings to
the user when using such an image (for example, commits into a
probed-raw backing file are prevented), to help them improve their
tooling.  But whether or not we make the probe results explicit, we
still warn the user to remind them to upgrade their workflow to supply
-F always.

iotest 114 specifically wants to create an unsafe image for later
amendment rather than defaulting to our new default of recording a
probed format, so it needs an update.  While touching it, expand it to
cover all of the various warnings enabled by this patch.  iotest 301
also shows a change to qcow messages.

bc5ee6da71 qcow2: Deprecate use of qemu-img amend to change backing file
The use of 'qemu-img amend' to change qcow2 backing files is not
tested very well.  In particular, our implementation has a bug where
if a new backing file is provided without a format, then the prior
format is blindly reused, even if this results in data corruption, but
this is not caught by iotests.

There are also situations where amending other options needs access to
the original backing file (for example, on a downgrade to a v2 image,
knowing whether a v3 zero cluster must be allocated or may be left
unallocated depends on knowing whether the backing file already reads
as zero), but the command line does not have a nice way to tell us
both the backing file to use for opening the image as well as the
backing file to install after the operation is complete.

Even if we do allow changing the backing file, it is redundant with
the existing ability to change backing files via 'qemu-img rebase -u'.
It is time to deprecate this support (leaving the existing behavior
intact, even if it is buggy), and at a point in the future, require
the use of only 'qemu-img rebase' for adjusting backing chain
relations, saving 'qemu-img amend' for changes unrelated to the
backing chain.

add8200dd1 block: Error if backing file fails during creation without -u
Back in commit 6e6e55f5 (Jul 2017, v2.10), we tweaked the code to warn
if the backing file could not be opened but the user gave a size,
unless the user also passes the -u option to bypass the open of the
backing file.  As one common reason for failure to open the backing
file is when there is mismatch in the requested backing format in
relation to what the backing file actually contains, we actually want
to open the backing file and ensure that it has the right format in as
many cases as possible.  iotest 301 for qcow demonstrates how
detecting explicit format mismatch is useful to prevent the creation
of an image that would probe differently than the user requested.  Now
is the time to finally turn the warning an error, as promised.

Note that the original warning was added prior to our documentation of
an official deprecation policy (eb22aeca, also Jul 2017), and because
the warning didn't mention the word "deprecated", we never actually
remembered to document it as such.  But the warning has been around
long enough that I don't see prolonging it another two releases.

0f10bf84a9 Deprecate TileGX port
Deprecate our TileGX target support:
 * we have no active maintainer for it
 * it has had essentially no contributions (other than tree-wide cleanups
   and similar) since it was first added
 * the Linux kernel dropped support in 2018, as has glibc

Note the deprecation in the manual, but don't try to print a warning
when QEMU runs -- printing unsuppressable messages is more obtrusive
for linux-user mode than it would be for system-emulation mode, and
it doesn't seem worth trying to invent a new suppressible-error
system for linux-user just for this.

32a354dc6c numa: forbid '-numa node, mem' for 5.1 and newer machine types
Deprecation period is run out and it's a time to flip the switch
introduced by cd5ff8333a.  Disable legacy option for new machine
types (since 5.1) and amend documentation.

'-numa node,memdev' shall be used instead of disabled option
with new machine types.

a1b40bda08 blockdev: Deprecate -drive with bogus interface type
Drives with interface types other than if=none are for onboard
devices.  Unfortunately, any such drives the board doesn't pick up can
still be used with -device, like this:

    $ qemu-system-x86_64 -nodefaults -display none -S -drive if=floppy,id=bogus,unit=7 -device ide-cd,drive=bogus -monitor stdio
    QEMU 5.0.50 monitor - type 'help' for more information
    (qemu) info block
    bogus: [not inserted]
	Attached to:      /machine/peripheral-anon/device[0]
	Removable device: not locked, tray closed
    (qemu) info qtree
    bus: main-system-bus
      type System
      [...]
	    bus: ide.1
	      type IDE
	      dev: ide-cd, id ""
--->		drive = "bogus"
		[...]
		unit = 0 (0x0)
      [...]

This kind of abuse has always worked.  Deprecate it:

    qemu-system-x86_64: -drive if=floppy,id=bogus,unit=7: warning: bogus if=floppy is deprecated, use if=none

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.

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.

Currently the per-target documentation for those targets that
implement semihosting includes a bit of text that goes into both the

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.

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

- images.rst: add toctree

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

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).

acab923dce qemu-block-drivers: Convert to rST
The qemu-block-drivers documentation is currently in
docs/qemu-block-drivers.texi in Texinfo format, which we present
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
