9ffcbe2a60 os-posix: Allow 'chroot' via '-run-with' and deprecate the old '-chroot' option
We recently introduced "-run-with" for options that influence the
runtime behavior of QEMU. This option has the big advantage that it
can group related options (so that it is easier for the users to spot
them) and that the options become introspectable via QMP this way.
So let's start moving more switches into this option group, starting
with "-chroot" now.

133789e1bf qga: Add new option --allow-rpcs
The allow-rpcs option accepts a comma-separated list of RPCs to
enable. This option is opposite to --block-rpcs. Using --block-rpcs
and --allow-rpcs at the same time is not allowed.

934676c7b7 ppc/pnv: SMT support for powernv
Set the TIR default value with the SMT thread index, and place some
standard limits on SMT configurations. Now powernv is able to boot
skiboot and Linux with a SMT topology, including booting a KVM guest.

There are several SPRs and other features (e.g., broadcast msgsnd)
that are not implemented, but not used by OPAL or Linux and can be
added incrementally.

71d72ececa 9pfs: deprecate 'proxy' backend
As recent CVE-2023-2861 (fixed by f6b0de53fb) once again showed, the 9p
'proxy' fs driver is in bad shape. Using the 'proxy' backend was already
discouraged for safety reasons before and we recommended to use the
'local' backend (preferably in conjunction with its 'mapped' security
model) instead, but now it is time to officially deprecate the 'proxy'
backend.

62c2b8760b hw/arm/sbsa-ref: use XHCI to replace EHCI
The current sbsa-ref cannot use EHCI controller which is only
able to do 32-bit DMA, since sbsa-ref doesn't have RAM below 4GB.
Hence, this uses XHCI to provide a usb controller with 64-bit
DMA capablity instead of EHCI.

We bump the platform version to 0.3 with this change.  Although the
hardware at the USB controller address changes, the firmware and
Linux can both cope with this -- on an older non-XHCI-aware
firmware/kernel setup the probe routine simply fails and the guest
proceeds without any USB.  (This isn't a loss of functionality,
because the old USB controller never worked in the first place.) So
we can call this a backwards-compatible change and only bump the
minor version.

abf7ba310b docs: Document security implications of debugging
Now that the GDB stub explicitly implements reading host files (note
that it was already possible by changing the emulated code to open and
read those files), concerns may arise that it undermines security.

Document the status quo, which is that the users are already
responsible for securing the GDB connection themselves.

Using QOM correctly is increasingly important to maintaining a modern

  - at least mention properties
  - mention TYPE_OBJECT and TYPE_DEVICE
  - talk about why we have realize/unrealize
  - mention the QOM tree
  - lightly re-arrange the order we mention things

When new dependencies and packages are added to containers, its important to
run CI container generation pipelines on gitlab to make sure that there are no
obvious conflicts between packages that are being added and those that are
already present. Running CI container pipelines will make sure that there are
no such breakages before we commit the change updating the containers. Add a
line in the documentation reminding developers to run the pipeline before
submitting the change. It will also ease the life of the maintainers.

745c42912a vfio/migration: Add support for switchover ack capability
Loading of a VFIO device's data can take a substantial amount of time as
the device may need to allocate resources, prepare internal data
structures, etc. This can increase migration downtime, especially for
VFIO devices with a lot of resources.

To solve this, VFIO migration uAPI defines "initial bytes" as part of
its precopy data stream. Initial bytes can be used in various ways to
improve VFIO migration performance. For example, it can be used to
transfer device metadata to pre-allocate resources in the destination.
However, for this to work we need to make sure that all initial bytes
are sent and loaded in the destination before the source VM is stopped.

Use migration switchover ack capability to make sure a VFIO device's
initial bytes are sent and loaded in the destination before the source
stops the VM and attempts to complete the migration.
This can significantly reduce migration downtime for some devices.

eda7362af9 vfio/migration: Add VFIO migration pre-copy support
Pre-copy support allows the VFIO device data to be transferred while the
VM is running. This helps to accommodate VFIO devices that have a large
amount of data that needs to be transferred, and it can reduce migration
downtime.

Pre-copy support is optional in VFIO migration protocol v2.
Implement pre-copy of VFIO migration protocol v2 and use it for devices
that support it. Full description of it can be found in the following
Linux commit: 4db52602a607 ("vfio: Extend the device migration protocol
with PRE_COPY").

6b90a4cdc0 escc: emulate dip switch language layout settings on SUN keyboard
SUN Type 4, 5 and 5c keyboards have dip switches to choose the language layout
of the keyboard. Solaris makes an ioctl to query the value of the dipswitches
and uses that value to select keyboard layout.  Also the SUN bios like the one
in the file ss5.bin uses this value to support at least some keyboard layouts.
However, the OpenBIOS provided with qemu is hardcoded to always use an US
keyboard layout.

Before this patch, qemu allways gave dip switch value 0x21 (US keyboard),
this patch uses a command line switch like
"-global escc.chnA-sunkbd-layout=de" to select dip switch value. A table is
used to lookup values from arguments like:

-global escc.chnA-sunkbd-layout=fr
-global escc.chnA-sunkbd-layout=es

But the patch also accepts numeric dip switch values directly:

-global escc.chnA-sunkbd-layout=0x2b
-global escc.chnA-sunkbd-layout=43

Both values above are the same and select swedish keyboard as explained in
table 3-15 at
https://docs.oracle.com/cd/E19683-01/806-6642/new-43/index.html

Unless you want to do a full Solaris installation but happen to have
access to a Sun bios file, the easiest way to test that the patch works
is to:

qemu-system-sparc -global escc.chnA-sunkbd-layout=sv -bios /path/to/ss5.bin

If you already happen to have a Solaris installation in a qemu disk image
file you can easily try different keyboard layouts after this patch is
applied.

1ddd2ff9cd gitlab: allow overriding name of the upstream repository
The CI rules have special logic for what happens in upstream. To enable
contributors who modify CI rules to test this logic, however, they need
to be able to override which repo is considered upstream. This
introduces the 'QEMU_CI_UPSTREAM' variable

  git push gitlab <branch> -o ci.variable=QEMU_CI_UPSTREAM=berrange

to make it look as if my namespace is the actual upstream. Namespace in
this context refers to the path fragment in gitlab URLs that is above
the repository. Typically this will be the contributor's gitlab login
name.

d4c7a56539 gitlab: centralize the container tag name
We use a fixed container tag of 'latest' so that contributors' forks
don't end up with an ever growing number of containers as they work
on throwaway feature branches.

This fixed tag causes problems running CI upstream in stable staging
branches, however, because the stable staging branch will publish old
container content that clashes with that needed by primary staging
branch. This makes it impossible to reliably run CI pipelines in
parallel in upstream for different staging branches.

This introduces $QEMU_CI_CONTAINER_TAG global variable as a way to
change which tag container publishing uses. Initially it can be set
by contributors as a git push option if they want to override the
default use of 'latest' eg

  git push gitlab <branch> -o ci.variable=QEMU_CONTAINER_TAG=fish

this is useful if contributors need to run pipelines for different
branches concurrently in their forks.

14180d6221 bswap: Add the ability to store to an unaligned 24 bit field
CXL has 24 bit unaligned fields which need to be stored to.  CXL is
specified as little endian.

Define st24_le_p() and the supporting functions to store such a field
from a 32 bit host native value.

The use of b, w, l, q as the size specifier is limiting.  So "24" was
used for the size part of the function name.

733766cd37 hw/arm: introduce xenpvh machine
Add a new machine xenpvh which creates a IOREQ server to register/connect with
Xen Hypervisor.

Optional: When CONFIG_TPM is enabled, it also creates a tpm-tis-device, adds a
TPM emulator and connects to swtpm running on host machine via chardev socket
and support TPM functionalities for a guest domain.

Extra command line for aarch64 xenpvh QEMU to connect to swtpm:
    -chardev socket,id=chrtpm,path=/tmp/myvtpm2/swtpm-sock \
    -tpmdev emulator,id=tpm0,chardev=chrtpm \
    -machine tpm-base-addr=0x0c000000 \

swtpm implements a TPM software emulator(TPM 1.2 & TPM 2) built on libtpms and
provides access to TPM functionality over socket, chardev and CUSE interface.
Github repo: https://github.com/stefanberger/swtpm
Example for starting swtpm on host machine:
    mkdir /tmp/vtpm2
    swtpm socket --tpmstate dir=/tmp/vtpm2 \
    --ctrl type=unixio,path=/tmp/vtpm2/swtpm-sock &

f65f6ad5a7 aspeed: Introduce a "bmc-console" machine option
Most of the Aspeed machines use the UART5 device for the boot console,
and QEMU connects the first serial Chardev to this SoC device for this
purpose. See routine connect_serial_hds_to_uarts().

Nevertheless, some machines use another boot console, such as the fuji,
and commit 5d63d0c76c ("hw/arm/aspeed: Allow machine to set UART
default") introduced a SoC class attribute 'uart_default' and property
to be able to change the boot console device. It was later changed by
commit d2b3eaefb4 ("aspeed: Refactor UART init for multi-SoC machines").

The "bmc-console" machine option goes a step further and lets the user define
the UART device from the QEMU command line without introducing a new

/dev/ttyS2 under Linux) instead of the default UART5, one would use :

  -M ast2500-evb,bmc-console=uart3

e8e4298fea tests: Use separate virtual environment for avocado
This reverts commits eea2d14117 ("Makefile: remove $(TESTS_PYTHON)",
2023-05-26) and 9c6692db55 ("tests: Use configure-provided pyvenv for
tests", 2023-05-18).

Right now, there is a conflict between wanting a ">=" constraint when
using a distro-provided package and wanting a "==" constraint when
installing Avocado from PyPI; this would provide the best of both worlds
in terms of resiliency for both distros that have required packages and
distros that don't.

The conflict is visible also for meson, where we would like to install
the latest 0.63.x version but also accept a distro 1.1.x version.
But it is worse for avocado, for two reasons:

1) we cannot use an "==" constraint to install avocado if the venv
includes a system avocado.  The distro will package plugins that have
"==" constraints on the version that is included in the distro, and, using
"pip install avocado==88.1" on a venv that includes system packages will
result in this error:

   ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
   avocado-framework-plugin-varianter-yaml-to-mux 98.0 requires avocado-framework==98.0, but you have avocado-framework 88.1 which is incompatible.
   avocado-framework-plugin-result-html 98.0 requires avocado-framework==98.0, but you have avocado-framework 88.1 which is incompatible.
   make[1]: Leaving directory '/home/berrange/src/virt/qemu/build'

2) we cannot use ">=" either if the venv does _not_ include a system
avocado, because that would result in the installation of v101.0 which
is the one we've just reverted.

So the idea is to encode the dependencies as an (acceptable, locked)
tuple, like this hypothetical TOML that would be committed inside
python/ and used by mkvenv.py:

  [meson]
  meson = { minimum = "0.63.0", install = "0.63.3", canary = "meson" }

  [docs]
  # 6.0 drops support for Python 3.7
  sphinx = { minimum = "1.6", install = "<6.0", canary = "sphinx-build" }
  sphinx_rtd_theme = { minimum = "0.5" }

  [avocado]
  avocado-framework = { minimum = "88.1", install = "88.1", canary = "avocado" }

Once this is implemented, it would also be possible to install avocado in
pyvenv/ using "mkvenv.py ensure", thus using the distro package on Fedora
and CentOS Stream (the only distros where it's available).  But until
this is implemented, keep avocado in a separate venv.  There is still the
benefit of using a single python for meson custom_targets and for sphinx.

06831001ac atomics: eliminate mb_read/mb_set
qatomic_mb_read and qatomic_mb_set were the very first atomic primitives
introduced for QEMU; their semantics are unclear and they provide a false
sense of safety.

The last use of qatomic_mb_read() has been removed, so delete it.
qatomic_mb_set() instead can survive as an optimized
qatomic_set()+smp_mb(), similar to Linux's smp_store_mb(), but
rename it to qatomic_set_mb() to match the order of the two
operations.

5cf899e215 qcow2: Explicit mention of padding bytes
Although we already covered the need for padding bytes with our
changes in commit 3ae3fcfa, commit 66fcbca5 (both v5.0.0) added one
byte and relied on the rest of the text for implicitly covering 7
padding bytes.  For consistency with other parts of the header (such
as the header extension format listing padding from n - m, or the
snapshot table entry listing variable padding), we might as well call
out the remaining 7 bytes as padding until such time (as any) as they
gain another meaning.

7e62609353 docs: Document decodetree named field syntax
Document the named field syntax that we want to implement for the
decodetree script.  This allows a field to be defined in terms of
some other field that the instruction pattern has already set, for
example:

   %sz_imm 10:3 sz:3 !function=expand_sz_imm

to allow a function to be passed both an immediate field from the
instruction and also a sz value which might have been specified by
the instruction pattern directly (sz=1, etc) rather than being a
simple field within the instruction.

Note that the restriction on not having the format referring to the
pattern and the pattern referring to the format simultaneously is a
restriction of the decoder generator rather than inherently being a
silly thing to do.

qmp-intro.txt is quite small and provides very little information
that isn't already in the documentation elsewhere.  Fold the example
command lines into qemu-options.hx, and delete the now-unneeded plain
text document.

While we're touching the qemu-options.hx documentation text,
wordsmith it a little bit and improve the rST formatting.

adacc814f5 hw/cxl: Multi-Region CXL Type-3 Devices (Volatile and Persistent)
This commit enables each CXL Type-3 device to contain one volatile
memory region and one persistent region.

Two new properties have been added to cxl-type3 device initialization:
    [volatile-memdev] and [persistent-memdev]

The existing [memdev] property has been deprecated and will default the
memory region to a persistent memory region (although a user may assign
the region to a ram or file backed region). It cannot be used in
combination with the new [persistent-memdev] property.

Partitioning volatile memory from persistent memory is not yet supported.

Volatile memory is mapped at DPA(0x0), while Persistent memory is mapped
at DPA(vmem->size), per CXL Spec 8.2.9.8.2.0 - Get Partition Info.

fe3ab4eb2d docs/devel: update build system docs
configure is only doing compiler and host setup now, so adjust the
relevant documentation.  It is also possible to build emulators with
ninja directly if one is so inclined, so mention that as well.

The Python virtual environment set up is a new major task of configure
as well.  Mention it in the list of produced files, while leaving it
for a future patch to document how it works and how ``mkvenv ensure``
is used.

91608e2a44 docs: Convert u2f.txt to rST
Convert the u2f.txt file to rST, and place it in the right place
in our manual layout. The old text didn't fit very well into our
manual style, so the new version ends up looking like a rewrite,
although some of the original text is preserved:

 * the 'building' section of the old file is removed, since we
   generally assume that users have already built QEMU
 * some rather verbose text has been cut back
 * document the passthrough device first, on the assumption
   that's most likely to be of interest to users
 * cut back on the duplication of text between sections
 * format example command lines etc with rST

As it's a short document it seemed simplest to do this all
in one go rather than try to do a minimal syntactic conversion
and then clean up the wording and layout.

5591b74511 Python: Drop support for Python 3.6
Python 3.6 was EOL 2021-12-31. Newer versions of upstream libraries have
begun dropping support for this version and it is becoming more
cumbersome to support. Avocado-framework and qemu.qmp each have their
own reasons for wanting to drop Python 3.6, but won't until QEMU does.

Versions of Python available in our supported build platforms as of today,
with optional versions available in parentheses:

openSUSE Leap 15.4: 3.6.15 (3.9.10, 3.10.2)
CentOS Stream 8:    3.6.8  (3.8.13, 3.9.16)
CentOS Stream 9:    3.9.13
Fedora 36:          3.10
Fedora 37:          3.11
Debian 11:          3.9.2
Alpine 3.14, 3.15:  3.9.16
Alpine 3.16, 3.17:  3.10.10
Ubuntu 20.04 LTS:   3.8.10
Ubuntu 22.04 LTS:   3.10.4
NetBSD 9.3:         3.9.13*
FreeBSD 12.4:       3.9.16
FreeBSD 13.1:       3.9.16
OpenBSD 7.2:        3.9.16

Note: Our VM tests install 3.9 explicitly for FreeBSD and 3.10 for
NetBSD; the default for "python" or "python3" in FreeBSD is
3.9.16. NetBSD does not appear to have a default meta-package, but
offers several options, the lowest of which is 3.7.15. "python39"
appears to be a pre-requisite to one of the other packages we request in
tests/vm/netbsd. pip, ensurepip and other Python essentials are
currently only available for Python 3.10 for NetBSD.

CentOS and OpenSUSE support parallel installation of multiple Python
interpreters, and binaries in /usr/bin will always use Python 3.6.  However,
the newly introduced support for virtual environments ensures that all build
steps that execute QEMU Python code use a single interpreter.

Since it is safe to under our supported platform policy, bump our
minimum supported version of Python to 3.7.

ed8d95182b meson: Pass -j option to sphinx
Save a bit of build time by passing the number of jobs option to
sphinx.

We cannot use  the -j option from make because  meson does not support
setting build time parameters for custom targets. Use nproc instead or
the equivalent sphinx option "-j  auto", if that is available (version
>=1.7.0).

Also make sure our plugins support parallelism and report it properly
to sphinx. Particularly, implement the merge_domaindata method in
DBusDomain that is used to merge in data from other subprocesses.

obvious conflicts between packages that are being added and those that are
already present. Running CI container pipelines will make sure that there are
no such breakages before we commit the change updating the containers. Add a
line in the documentation reminding developers to run the pipeline before
submitting the change. It will also ease the life of the maintainers.

80bd81cadd util/async-teardown: wire up query-command-line-options
Add new -run-with option with an async-teardown=on|off parameter. It is
visible in the output of query-command-line-options QMP command, so it
can be discovered and used by libvirt.

The option -async-teardown is now redundant, deprecate it.

d6359e150d docs: Remove unused weirdly-named cross-reference targets
In the doc sources, we have a few cross-reference targets with odd
names "pcsys_005fxyz".  These are the legacy of the semi-automated
conversion of the old info docs to rST (the '005f' is because ASCII
0x5f is '_' and the old info link names had underscores in them).

Remove the targets which nothing links to, and rename the two targets
which are used to something a bit more descriptive.

08349786c8 qapi: Relax doc string @name: description indentation rules
The QAPI schema doc comment language provides special syntax for
command and event arguments, struct and union members, alternate
branches, enumeration values, and features: descriptions starting with
"@name:".

By convention, we format them like this:

    # @name: Lorem ipsum dolor sit amet, consectetur adipiscing elit,
    #        sed do eiusmod tempor incididunt ut labore et dolore
    #        magna aliqua.

Okay for names as short as "name", but we have much longer ones.  Their
description gets squeezed against the right margin, like this:

    # @dirty-sync-missed-zero-copy: Number of times dirty RAM synchronization could
    #                               not avoid copying dirty pages. This is between
    #                               0 and @dirty-sync-count * @multifd-channels.
    #                               (since 7.1)

The description text is effectively just 50 characters wide.  Easy
enough to read, but can be cumbersome to write.

The awkward squeeze against the right margin makes people go beyond it,
which produces two undesirables: arguments about style, and descriptions
that are unnecessarily hard to read, like this one:

    # @postcopy-vcpu-blocktime: list of the postcopy blocktime per vCPU.  This is
    #                           only present when the postcopy-blocktime migration capability
    #                           is enabled. (Since 3.0)

We could instead format it like

    # @postcopy-vcpu-blocktime:
    # list of the postcopy blocktime per vCPU.  This is only present
    # when the postcopy-blocktime migration capability is
    # enabled. (Since 3.0)

or, since the commit before previous, like

    # @postcopy-vcpu-blocktime:
    # 	  list of the postcopy blocktime per vCPU.  This is only present
    # 	  when the postcopy-blocktime migration capability is
    # 	  enabled. (Since 3.0)

However, I'd rather have

    # @postcopy-vcpu-blocktime: list of the postcopy blocktime per vCPU.
    #     This is only present when the postcopy-blocktime migration
    #     capability is enabled.  (Since 3.0)

because this is how rST field and option lists work.

To get this, we need to let the first non-blank line after the
"@name:" line determine expected indentation.

This fills up the indentation pitfall mentioned in
docs/devel/qapi-code-gen.rst.  A related pitfall still exists.  Update
the text to show it.

f57e1d05bf sphinx/qapidoc: Do not emit TODO sections into user manuals
QAPI doc comments are for QMP users: they go into the "QEMU QMP
Reference Manual" and the "QEMU Storage Daemon QMP Reference Manual".

The doc comment TODO sections are for somebody else, namely for the
people who can do: developers.  Do not emit them into the user
manuals.

This elides the following TODOs:

* SchemaInfoCommand

  # TODO: @success-response (currently irrelevant, because it's QGA, not QMP)

  This is a note to developers adding introspection to the guest
  agent.  It makes no sense to users.

* @query-hotpluggable-cpus

  # TODO: Better documentation; currently there is none.

  This is a reminder for developers.  It doesn't help users.

* @device_add

  # TODO: This command effectively bypasses QAPI completely due to its
  #       "additional arguments" business.  It shouldn't have been added to
  #       the schema in this form.  It should be qapified properly, or
  #       replaced by a properly qapified command.

  Likewise.

Eliding them is an improvement.

We have two FIXME notes.  These FIXMEs are for QAPI developers.  They
are not useful for QAPI schema developers.  They are marked up as
admonitions, which makes them look important in generated HTML.

Turn them into comments.  QAPI developers will still see them (they
read and write the .rst).  QAPI schema developers may still see
them (if they read the .rst instead of the generated .html), but "this
is just for QAPI developers" should be more obvious.

34c18203d4 qmp: Deprecate 'singlestep' member of StatusInfo
The 'singlestep' member of StatusInfo has never done what the QMP
documentation claims it does.  What it actually reports is whether
TCG is working in "one guest instruction per translation block" mode.

We no longer need this field for the HMP 'info status' command, as
we've moved that information to 'info jit'.  It seems unlikely that
anybody is monitoring the state of this obscure TCG setting via QMP,
especially since QMP provides no means for changing the setting.  So
simply deprecate the field, without providing any replacement.

Until we do eventually delete the member, correct the misstatements
in the QAPI documentation about it.

If we do find that there are users for this, then the most likely way
we would provide replacement access to the information would be to
put the accelerator QOM object at a well-known path such as
/machine/accel, which could then be used with the existing qom-set
and qom-get commands.

e9ccfdd91d hmp: Add 'one-insn-per-tb' command equivalent to 'singlestep'
The 'singlestep' HMP command is confusing, because it doesn't
actually have anything to do with single-stepping the CPU.  What it
does do is force TCG emulation to put one guest instruction in each
TB, which can be useful in some situations.

Create a new HMP command  'one-insn-per-tb', so we can document that
'singlestep' is just a deprecated synonym for it, and eventually
perhaps drop it.

We aren't obliged to do deprecate-and-drop for HMP commands,
but it's easy enough to do so, so we do.

c110102898 qapi: Fix bullet list markup in documentation
Peter Maydell's commit 100cc4fe0f explains:

    rST insists on a blank line before and after a bulleted list [...]
    Add some extra blank lines in the doc comments so they're
    acceptable rST input.

It missed one in qapi/trace.json.

Paolo Bonzini later added another instance in qapi/stats.json,
providing further, if unintended, evidence for his quip that rST is
the Perl of ASCII-based markups.

Both are parsed as ordinary paragraph, resulting in garbled output.

John Snow missed the need for a blank line when converting
docs/devel/qapi-code-gen.txt to rST.

Add the blank lines we need to get the bullet lists recognized as
such.

Kevin Wolf and Lukas Straub added two more, but indented.  Sphinx
recognizes them as (indented) bullet lists.  The indentation looks
slightly off.

Insert a blank line and delete the extra indentation.

Fixes: 100cc4fe0f (qapi: Add blank lines before bulleted lists)
Fixes: 467ef823d8 (qmp: add filtering of statistics by target vCPU)

f1a787b5f4 qapi: @foo should be used to reference, not `foo`
Documentation suggests @foo is merely shorthand for ``foo``.  It's
not, it carries additional meaning: it's a reference to a QAPI schema
name.

Reword the documentation to spell that out.

Fix up the few ``foo`` that should be @foo.

Convert the pci-ids document from plain text to reStructuredText.

I opted to use definition-lists here because rST tables are
super-clunky, and actually formatting these as tables didn't
seem necessary.

de3b3f529d qapi: Require boxed for conditional command and event arguments
The C code generator fails to honor 'if' conditions of command and
event arguments.

For instance, tests/qapi-schema/qapi-schema-test.json has

    { 'event': 'TEST_IF_EVENT',
      'data': { 'foo': 'TestIfStruct',
		'bar': { 'type': ['str'], 'if': 'TEST_IF_EVT_ARG' } },
      'if': { 'all': ['TEST_IF_EVT', 'TEST_IF_STRUCT'] } }

Generated tests/test-qapi-events.h fails to honor the TEST_IF_EVT_ARG
condition:

    #if defined(TEST_IF_EVT) && defined(TEST_IF_STRUCT)
    void qapi_event_send_test_if_event(TestIfStruct *foo, strList *bar);
    #endif /* defined(TEST_IF_EVT) && defined(TEST_IF_STRUCT) */

Only uses so far are in tests/.

We could fix the generator to emit something like

    #if defined(TEST_IF_EVT) && defined(TEST_IF_STRUCT)
    void qapi_event_send_test_if_event(TestIfStruct *foo
    #if defined(TEST_IF_EVT_ARG)
                    , strList *bar
    #endif
                    );
    #endif /* defined(TEST_IF_EVT) && defined(TEST_IF_STRUCT) */

Ugly.  Calls become similarly ugly.  Not worth fixing.

Conditional arguments work fine with 'boxed': true, simply because
complex types with conditional members work fine.  Not worth breaking.

Reject conditional arguments unless boxed.

Move the tests cases covering unboxed conditional arguments out of
tests/qapi-schema/qapi-schema-test.json.  Cover boxed conditional
arguments there instead.

f21e95ee97 docs: vhost-user: Add Xen specific memory mapping support
The current model of memory mapping at the back-end works fine where a
standard call to mmap() (for the respective file descriptor) is enough
before the front-end can start accessing the guest memory.

There are other complex cases though where the back-end needs more
information and simple mmap() isn't enough. For example Xen, a type-1
hypervisor, currently supports memory mapping via two different methods,
foreign-mapping (via /dev/privcmd) and grant-dev (via /dev/gntdev). In
both these cases, the back-end needs to call mmap() and ioctl(), with
extra information like the Xen domain-id of the guest whose memory we
are trying to map.

Add a new protocol feature, 'VHOST_USER_PROTOCOL_F_XEN_MMAP', which lets
the back-end know about the additional memory mapping requirements.
When this feature is negotiated, the front-end will send the additional
information within the memory regions themselves.

17c67f6849 docs: vhost-user: Define memory region separately
The same layout is defined twice, once in "single memory region
description" and then in "memory regions description".

Separate out details of memory region from these two and reuse the same
definition later on.

While at it, also rename "memory regions description" to "multiple
memory regions description", to avoid potential confusion around similar
names. And define single region before multiple ones.

This is just a documentation optimization, the protocol remains the same.

fbd945e783 docs: Add support for TPM devices over I2C bus
This is a documentation change for I2C TPM device support.

Qemu already supports devices attached to ISA and sysbus.
This drop adds support for the I2C bus attached TPM devices.

0f40f7cabe docs/devel/kconfig.rst: Fix incorrect markup
In rST markup syntax, the inline markup (*italics*, **bold** and
``monospaced``) must be separated from the surrending text by
non-word characters, otherwise it is not interpreted as markup.
To force interpretation as markup in the middle of a word,
you need to use a backslash-escaped space (which will not
appear as a space in the output).

Fix a missing backslash-space in this file, which meant that the ``
after "select" was output literally and the monospacing was
incorrectly extended all the way to the end of the next monospaced
word.

dd17143fce target/arm: Implement FEAT_PAN3
FEAT_PAN3 adds an EPAN bit to SCTLR_EL1 and SCTLR_EL2, which allows
the PAN bit to make memory non-privileged-read/write if it is
user-executable as well as if it is user-read/write.

Implement this feature and enable it in the AArch64 'max' CPU.

000eebcfe8 docs: explain effect of smp_read_barrier_depends() on modern architectures
The documentation for smp_read_barrier_depends() does not mention the architectures
for which it is an optimization, for example ARM and PPC.  As a result, it is not
clear to the reader why one would use it.  Relegate Alpha to a footnote together
with other architectures where it is equivalent to smp_rmb().

8635a3a153 Revert "docs/about/deprecated: Deprecate 32-bit arm hosts for system emulation"
This reverts commit 1d0a8eba38.

The commit made the wrong assumption that 64-bit distros are most
common these days on arm devices, but as Liviu Ionescu pointed out,
the recommended OS for the very popular Raspberry Pi boards is still
the 32-bit variant, and thus likely still used by a lot of people:

 https://www.raspberrypi.com/software/operating-systems/

Thus it's likely still a little bit too early to put this host
environment on the deprecation list and we should wait a little
bit longer 'til 64-bit distros are the predominant ones.

364206640c docs/sphinx/kerneldoc.py: Honour --enable-werror
Currently, the kerneldoc Sphinx plugin doesn't honour the
--enable-werror configure option, so its warnings are never fatal.
This is because although we do pass sphinx-build the -W switch, the
warnings from kerneldoc are produced by the scripts/kernel-doc script
directly and don't go through Sphinx's "emit a warning" function.

When --enable-werror is in effect, pass sphinx-build an extra
argument -Dkerneldoc_werror=1.  The kerneldoc plugin can then use
this to determine whether it should be passing the kernel-doc script
-Werror.

We do this because there is no documented mechanism for
a Sphinx plugin to determine whether sphinx-build was
passed -W or not; if one is provided then we can switch to
that at a later date:

Configuring the accelerator should nowadays be done via the "-accel"
command line parameter, and thus via the "[accel]" section in config
files. We also need this change for the upcoming qtests that will
use these config files, since the qtests are already using "-accel"
for setting the "qtest" accelerator and QEMU does not like mixing
"-accel ..." and "-machine accel=...".

1d0a8eba38 docs/about/deprecated: Deprecate 32-bit arm hosts for system emulation
For running QEMU in system emulation mode, the user needs a rather
strong host system, i.e. not only an embedded low-frequency controller.
All recent beefy arm host machines should support 64-bit now, it's
unlikely that anybody is still seriously using QEMU on a 32-bit arm
CPU, so we deprecate the 32-bit arm hosts here to finally save use
some time and precious CI minutes.

96dcf1aaca docs/about/build-platforms: Refine the distro support policy
For long-term distributions that release a new version only very
seldom, we limit the support to five years after the initial release.
Otherwise, we might need to support distros like openSUSE 15 for
up to 7 or even more years in total due to our "two more years
after the next major release" rule, which is just way too much to
handle in a project like QEMU that only has limited human resources.

ff00bed189 qatomic: add smp_mb__before/after_rmw()
On ARM, seqcst loads and stores (which QEMU does not use) are compiled
respectively as LDAR and STLR instructions.  Even though LDAR is
also used for load-acquire operations, it also waits for all STLRs to
leave the store buffer.  Thus, LDAR and STLR alone are load-acquire
and store-release operations, but LDAR also provides store-against-load
ordering as long as the previous store is a STLR.

Compare this to ARMv7, where store-release is DMB+STR and load-acquire
is LDR+DMB, but an additional DMB is needed between store-seqcst and
load-seqcst (e.g. DMB+STR+DMB+LDR+DMB); or with x86, where MOV provides
load-acquire and store-release semantics and the two can be reordered.

Likewise, on ARM sequentially consistent read-modify-write operations only
need to use LDAXR and STLXR respectively for the load and the store, while
on x86 they need to use the stronger LOCK prefix.

In a strange twist of events, however, the _stronger_ semantics
of the ARM instructions can end up causing bugs on ARM, not on x86.
The problems occur when seqcst atomics are mixed with relaxed atomics.

QEMU's atomics try to bridge the Linux API (that most of the developers
are familiar with) and the C11 API, and the two have a substantial
difference:

- in Linux, strongly-ordered atomics such as atomic_add_return() affect
  the global ordering of _all_ memory operations, including for example
  READ_ONCE()/WRITE_ONCE()

- in C11, sequentially consistent atomics (except for seq-cst fences)
  only affect the ordering of sequentially consistent operations.
  In particular, since relaxed loads are done with LDR on ARM, they are
  not ordered against seqcst stores (which are done with STLR).

QEMU implements high-level synchronization primitives with the idea that
the primitives contain the necessary memory barriers, and the callers can
use relaxed atomics (qatomic_read/qatomic_set) or even regular accesses.
This is very much incompatible with the C11 view that seqcst accesses
are only ordered against other seqcst accesses, and requires using seqcst
fences as in the following example:

   qatomic_set(&y, 1);            qatomic_set(&x, 1);
   smp_mb();                      smp_mb();
   ... qatomic_read(&x) ...       ... qatomic_read(&y) ...

When a qatomic_*() read-modify write operation is used instead of one
or both stores, developers that are more familiar with the Linux API may
be tempted to omit the smp_mb(), which will work on x86 but not on ARM.

This nasty difference between Linux and C11 read-modify-write operations
has already caused issues in util/async.c and more are being found.
Provide something similar to Linux smp_mb__before/after_atomic(); this
has the double function of documenting clearly why there is a memory
barrier, and avoiding a double barrier on x86 and s390x systems.

The new macro can already be put to use in qatomic_mb_set().

171080d891 testing: update ubuntu2004 to ubuntu2204
The 22.04 LTS release has been out for almost a year now so its time
to update all the remaining images to the current LTS. We can also
drop some hacks we need for older clang TSAN support.

We will keep the ubuntu2004 container around for those who wish to

Python 3.6 is at end-of-life.  Update the libvirt-ci module to a
version that supports overrides for targets and package mappings;
this way, QEMU can use the newer versions provided by CentOS 8 (Python
3.8) and OpenSUSE 15.3 (Python 3.9).

fa1ce1dda9 docs/devel: update and clarify lcitool instructions
Shorten a bit the description of what libvirt-ci does, the name of the
data files is not relevant at that point.  However, the procedures to add
new build prerequisites are lacking some information, particularly with
respect to regenerating the output test files for lcitool's unit tests.
While at it, also update the paths in the libvirt-ci repository.

1b1be8d3cc meson: stop looking for 'sphinx-build-3'
Once upon a time, "sphinx-build" on certain RPM platforms invoked
specifically a Python 2.x version, while "sphinx-build-3" was a distro
shim for the Python 3.x version.

These days, none of our supported platforms utilize a 2.x version, and
those that still have 'sphinx-build-3' make it a symbolic link to
'sphinx-build'.  Not searching for 'sphinx-build-3' will prefer
pip/venv installed versions of sphinx if they're available.

This adds an extremely convenient ability to test document building
ability in QEMU across multiple versions of Sphinx for the purposes of
compatibility testing.

adf4c9bd2e meson: fix dependency on qemu-keymap
When qemu-keymap is not available on the host, and enable-xkbcommon
is specified, parallel make fails with:

  % make clean
  ...
  % make -j 32
  ...
  FAILED: pc-bios/keymaps/is
  ./qemu-keymap -f pc-bios/keymaps/is -l is
  /bin/sh: ./qemu-keymap: No such file or directory
  ... many similar messages ...

The code always runs find_program, rather than waiting to build
qemu-keymap, because it looks for CONFIG_XKBCOMMON in config_host
rather than config_host_data.  Making serially succeeds, by soft
linking files from pc-bios/keymaps, but that is not the desired
result for enable-xkbcommon.

Examining all occurrences of 'in config_host' for similar bugs shows one
instance in the docs, which is also fixed here.

Fixes: 4113f4cfee ("meson: move xkbcommon to meson")

8d0efbcfa0 docs: build-platforms: refine requirements on Python build dependencies
Historically, the critical dependency for both building and running
QEMU has been the distro packages.  Because QEMU is written in C and C's
package management has been tied to distros (at least if you do not want
to bundle libraries with the binary, otherwise I suppose you could use
something like conda or wrapdb), C dependencies of QEMU would target the
version that is shipped in relatively old but still commonly used distros.

For non-C libraries, however, the situation is different, as these
languages have their own package management tool (cpan, pip, gem, npm,
and so on).  For some of these languages, the amount of dependencies
for even a simple program can easily balloon to the point that many
distros have given up on packaging non-C code.  For this reason, it has
become increasingly normal for developers to download dependencies into
a self-contained local environment, instead of relying on distro packages.

Fortunately, this affects QEMU only at build time, as qemu.git does
not package non-C artifacts such as the qemu.qmp package; but still,
as we make more use of Python, we experience a clash between a support
policy that is written for the C world, and dependencies (both direct
and indirect) that increasingly do not care for the distro versions
and are quick at moving past Python runtime versions that are declared
end-of-life.

For example, Python 3.6 has been EOL'd since December 2021 and Meson 0.62
(released the following March) already dropped support for it.  Yet,
Python 3.6 is the default version of the Python runtime for RHEL/CentOS
8 and SLE 15, respectively the penultimate and the most recent version
of two distros that QEMU would like to support.  (It is also the version
used by Ubuntu 18.04, but QEMU stopped supporting it in April 2022).

There are good reasons to move forward with the deprecation of Python
3.6 in QEMU as well: completing the configure->meson switch (which
requires Meson 0.63), and making the QAPI generator fully typed (which
requires newer versions of not just mypy but also Python, due to PEP563).

Fortunately, these long-term support distros do include newer versions of
the Python runtime.  However, these more recent runtimes only come with
a very small subset of the Python packages that the distro includes.
Because most dependencies are optional tests (avocado, mypy, flake8)
and Meson is bundled with QEMU, the most noticeably missing package is
Sphinx (and the readthedocs theme).  There are four possibilities:

* we change the support policy and stop supporting CentOS 8 and SLE 15;
  not a good idea since CentOS 8 is not an unreasonable distro for us to
  want to continue to support

* we keep supporting Python 3.6 until CentOS 8 and SLE 15 stop being
  supported.  This is a possibility---but we may want to revise the support
  policy anyway because SLE 16 has not even been released, so this would
  mean delaying those desirable reasons for perhaps three years;

* we support Python 3.6 just for building documentation, i.e. we are
  careful not to use Python 3.7+ features in our Sphinx extensions but are
  free to use them elsewhere.  Besides being more complicated to understand
  for developers, this can be quite limiting; parts of the QAPI generator
  run at sphinx-build time, which would exclude one of the areas which
  would benefit from a newer version of the runtime;

* we only support Python 3.7+, which means CentOS 8 CI and users
  have to either install Sphinx from pip or disable documentation.

This proposed update to the support policy chooses the last of these
possibilities.  It does by modifying three aspects of the support
policy:

* it introduces different support periods for *native* vs. *non-native*
  dependencies.  Non-native dependencies are currently Python ones only,
  and for simplicity the policy only mentions Python; however, the concept
  generalizes to other languages with a well-known upstream package
  manager, that users of older distributions can fetch dependencies from;

* it opens up the possibility of taking non-native dependencies from their
  own package index instead of using the version in the distribution.  The
  wording right now is specific to dependencies that are only required at
  build time.  In the future we may have to refine it if, for example, parts
  of QEMU will be written in Rust; in that case, crates would be handled
  in a similar way to submodules and vendored in the release tarballs.

* it mentions specifically that optional build dependencies are excluded
  from the platform policy.  Tools such as mypy don't affect the ability
  to build QEMU and move fast enough that distros cannot standardize on
  a single version of them (for example RHEL9 does not package them at
  all, nor does it run them at rpmbuild time).  In other cases, such as
  cross compilers, we have alternatives.

Right now, non-native dependencies have to be download manually by
running "pip" before "configure".  In the future, it will be desirable
for configure to set up a virtual environment and download them in the
same way that it populates git submodules (but, in this case, without
vendoring them in the release tarballs).

Just like with submodules, this would make things easier for people
that can afford accessing the network in their build environment; the
option to populate the build environment manually would remain for
people whose build machines lack network access.  The change to the
support policy neither requires nor forbids this future change.

2c46bc240a docs: add an introduction to the system docs
Drop the frankly misleading quickstart section for a more rounded
introduction section. This new section gives an overview of the
accelerators as well as a high level introduction to some of the key
features of the emulator. We also expand on a general form for a QEMU
command line with a hopefully not too scary worked example of what
this looks like.

2da9d21360 semihosting: add semihosting section to the docs
The main reason to do this is to document our O_BINARY implementation
decision somewhere. However I've also moved some of the implementation
details out of qemu-options and added links between the two. As a
bonus I've highlighted the scary warnings about host access with the
appropriate RST tags.

90c167a1da docs/about/deprecated: Mark HAXM in QEMU as deprecated
The HAXM project has been retired (see https://github.com/intel/haxm#status),
so we should mark the code in QEMU as deprecated (and finally remove it
unless somebody else picks the project up again - which is quite unlikely
since there are now whpx and hvf on these operating systems, too).

Example of use:

    perf record qemu-x86_64 -perfmap ./a.out
    perf report

or

    perf record -k 1 qemu-x86_64 -jitdump ./a.out

a844873512 mips: Remove support for trap and emulate KVM
This support was limited to the Malta board, drop it.
I do not have a machine that can run VZ KVM, so I am assuming
that it works for -M malta as well.

Strahinja Jankovic
9be8a82c0e {hw/i2c,docs/system/arm}: Allwinner TWI/I2C Emulation
This patch implements Allwinner TWI/I2C controller emulation. Only
master-mode functionality is implemented.

The SPL boot for Cubieboard expects AXP209 PMIC on TWI0/I2C0 bus, so this is
first part enabling the TWI/I2C bus operation.

Since both Allwinner A10 and H3 use the same module, it is added for
both boards.

Docs are also updated for Cubieboard and Orangepi-PC board to indicate
I2C availability.

The file seems to contain perfectly valid rst syntax already, so
rename it to .rst and wire it up in the index.
